A NanoBioengineering Frontier for Next-Generation Optical Devices

Prof. Ardemis Boghossian, Institute of Chemical Sciences and Engineering, School of Basic Sciences, EPFL, Lausanne (CH)

WEEKLY BIOENGINEERING COLLOQUIA SERIES
(sandwiches served)

Abstract:
The vast expansion of available synthetic biology tools has led to explosive developments in the field of materials science. No longer confined to engineering just synthetic materials, the increased accessibility of these tools has pushed the frontier of materials science into the field of engineering biological and even living materials. By coupling the tunability of nanomaterials with the prospect of re-programming living devices, one can re-purpose biology to fulfill needs that are otherwise intractable using traditional engineering approaches.

Optical technologies in particular could benefit from capitalizing on untapped potential in coupling the optical properties of nanomaterials with the specificity and scalability of biological materials. This seminar highlights specific applications in optical sensing and light-harvesting energy technologies that exploit the synergistic coupling of nanobio-hybrid materials. We discuss the development of bio-conjugated single-walled carbon nanotubes (SWCNTs) for near-infrared fluorescence sensing and the application of these nanobioptic sensors for continuous measurements in living cells and organisms. We further explore the development living photovoltaics based on bioengineered, photosynthetic organisms with augmented capabilities.

IMX Seminar Series - Chiral Inorganic Nanostructures

Prof. Nicholas Kotov, University of Michigan USA

Early observation of strong circular dichroism for individual nanoparticles and their assemblies have developed into a rapidly expanding field of chiral inorganic nanostructures. The chiral inorganic nanostructures encompass sophisticated constructs from metals, semiconductors, ceramics, and nanocarbons with multiple chiral geometries with characteristic scales from Ångströms to microns. Such versatility enables their functional engineering over a broad range of physical and chemical properties inspiring multiple technological realizations exemplified by biosensing and optoelectronics.   
This talk will address (1) the origin of the uniquely high values of optical anisotropy; (2) the mechanisms of chirality transfer in inorganic materials; and (3) differences/similarities with chiral supramolecular, liquid crystal, and biological assemblies.  The role of chiral inorganic nanostructures in homochirality of life on Earth will be briefly discussed. An essential role of long-range correlations and a possibility of critical phenomena in chiral nanoassemblies that lead to emergence of exceptionally complex structures will be demonstrated.  
Essential milestones toward utilization of chiral nanoscale assemblies in enantioselective catalysis and metaoptics will be outlined. One of the novel venues for practical realizations of chiral nanoassemblies include photocatalytic C-C coupling in biomimetic chiral supraparticles and CD spectroscopy in terahertz spectral window with chiroplasmonic kirigami composites.

Direct Multipixel Imaging of an exo-Earth with a Solar Gravitational Lens Telescope

Prof. Slava Turyshev, NASA Jet Propulsion Laboratory / CALTECH

According to Einstein’s general theory of relativity, the solar gravity field acts as a lens that may be used focus and greatly amplify light from distant faint sources. Thanks to impressive optical properties of the Solar Gravitational Lens (SGL), in the near future, we could deploy a modest telescope at the focal region of the SGL for direct imaging of a potentially habitable Earth-like exoplanet with a megapixel resolution, not possible with any other astronomical tools. It could also provide high-resolution spectroscopic data to identify a variety of atmospheric biomarkers needed for unambiguous detection of an alien life form.

IGM Colloquium: Exact Model Reduction and Forced Response in High-Degree-of-Freedom Nonlinear Mechanical Systems

Prof. George Haller, Chair in Nonlinear Dynamics, Institute for Mechanical Systems, ETH Zürich

Abstract:
Despite major advances in computational power, mapping out the forced response of large, nonlinear mechanical systems for different forcing frequencies has remained a major challenge. One reason is the small damping in most engineered systems, which leads to exceedingly slow-decaying transients in direct numerical integration. Another reason is that computing periodic response is not a naturally parallelizable procedure; involving more processors tends to increase the computation time. As a consequence, forced response is typically computed after ad hoc reduction procedures are applied to the original mechanical system. In this talk, we describe a recent tool from dynamical systems, spectral submanifold theory, which enables a mathematically exact reduction of nonlinear oscillatory systems to low-dimensional invariant manifolds. With the help of this reduction, previously unimaginable computational speeds can be achieved in computing nonlinear forced response. The approach also enables the detection of detached branches (isolas) of the response curves that remain undetected by classical numerical continuation, yet are critically important for structural health monitoring. We discuss these results on various problems, including analytic, numerical, and experimental construction of spectral submanifolds and forced response curves.

PhD defense open seminar: In vivo diffusion magnetic resonance imaging of the white matter microstructure from dictionaries generated by Monte Carlo simulations: development and validation

Gaetan Rensonnet

Abstract:
Many neurological and psychiatric disorders are closely related to subtle alterations of white matter cells such as axons, i.e., the long cables interconnecting the different areas of gray matter. The ability to predict microstructural properties of those cells in vivo using a non-radiating technique would therefore have far-reaching consequences in neuroscience and in clinical practice. 
In this thesis, a framework was developed for the estimation of the white matter microstructure based on diffusion-weighted magnetic resonance imaging (DW-MRI), a non-invasive imaging modality sensitive to the micrometer-scale displacements of water molecules undergoing diffusion the brain. The proposed approach, dubbed microstructure fingerprinting, relied on numerical Monte Carlo simulations of water diffusion rather than on closed-form mathematical formulas. On a variety of small animal and healthy human subject experiments, it was shown to be more robust and interpretable than traditional models. The flexibility of the proposed method should allow various refinements to be incorporated in the future, ultimately advancing our understanding of the white matter and improving the management of brain disorders.

Shining Light on Metallomembranes - POB seminar

Saranya Pullanchery

This month we will have the pleasure to host Saranya Pullanchery  ,Post-doctoral Researcher in the Laboratory for fundamental BioPhotonics (LBP).

For organizational purposes (if you want to eat pizza!), please confirm your participation using this Doodle.

Hope to see you there,
The team of the EPFL Photonics Chapter
 
Abstract:
Metal ions in our body can form complexes with lipids in the cell membrane. Such interactions are chemically specific. Trace metal ions such as Cu2+ and more abundant ions such as Ca2+ form chemically distinct complexes with negatively charged lipids. We do not yet completely understand the role of such ion-lipid complexes in our body. Understanding the molecular mechanism of ion-lipid complexes is essential toward finding their physiological relevance.
In this talk, I will show how we utilize the interface-selective technique, vibrational sum frequency generation (SFG) spectroscopy to understand molecular level details of ion-lipid interactions. SFG spectroscopy uniquely provides vibrational spectrum of the interface.  We obtain information about surface charge and surface structure from the interfacial spectrum of water. Such details are typically not accessible using bulk spectroscopic techniques.  Combining the information from SFG spectroscopy and fluorescence microscopy, we find key differences in the mode of interaction of Cu2+, Zn2+ and Ca2+ ions with negatively charged lipid membranes.

Talk by Prof. Aram Harrow from MIT on Quantum Algorithms for Machine Learning

Prof. Aram Harrow (MIT)

The EPFL Quantum Computing Association is excited to invite you to the talk of Prof. Aram Harrow from MIT!

Title: Hybrid Classical-Quantum Algorithms for Optimization and Inference
Quantum Computers are known to have strengths in cryptography and quantum simulations, but what about Machine Learning? This would be a valuable application, but there are difficulties: small Quantum Computers must handle large data sets and the existing classical algorithms are already quite sophisticated. To address these challenges, Prof. Harrow will describe how hybrid classical-quantum algorithms can best exploit the strengths of both types of computers. 

About the speaker: Aram Harrow is an Associate Professor of Physics in the Massachusetts Institute of Technology's Center for Theoretical Physics. Harrow works in quantum information science and quantum computing. Together with Avinatan Hassidim and Seth Lloyd, he designed a quantum algorithm for linear systems of equations (the HHL algorithm), which in some cases exhibits an exponential advantage over the best classical algorithms. The algorithm has wide application in quantum machine learning. He is a steering committee member of Quantum Information Processing (QIP), the largest annual conference in the field of quantum computing. Harrow is a co-administrator of SciRate, a free and open access scientific collaboration network. He also co-runs a blog, The Quantum Pontiff. His collaborators include Peter Shor and Charles H. Bennett.

Education, research, and technology transfer in open source software: new possibilities for universities

Prof. Carlos Maltzahn

Abstract
The efficiency and speed of large communities that drive open source software projects such as Linux are hard to beat by individual companies. The robustness of these projects creates high valuations for companies who learned how to leverage these projects (e.g. IBM acquiring Red hat for $34-billion). But in universities we are just beginning to discover the new possibilities of open source software in education, research, and technology transfer. In education, open source software can be studied in class rooms and students can learn how to productively interact with open source software communities. Communities have developed tools which allow for fast orchestration and deployment of complex software systems in classrooms and can serve as a new kind of media for deep understanding. In research, open source software is commonly used to implement prototypes, run experiments and analyze data. But open source software can encompass entire experiments that, using orchestration and deployment tools, can be replicated by researchers and students alike. In technology transfer, promising software research prototypes can be made highly usable and useful by industry/university cooperative research centers that provide opportunities and funding for building developer communities for those prototypes.

In this talk I will present two examples of those new possibilities: first I will give an overview of the Center for Research in Open Source Software (cross.ucsc.edu) which I founded four years ago within UC Santa Cruz. CROSS successfully introduced an industry-sponsored research and incubator program currently funding four research fellows and three incubator fellows. In the second example, I will provide a closer look at one of the incubator projects which is providing programmable storage for databases and file systems (SkyhookDM) and how it relates to one of the research projects on “eusocial storage devices” that can act collectively.

Nanoparticles: from their production to their commercial application

Dr. Michaël ROSSIER
Avantama AG, Stäfa (Zurich), Switzerland

ChE-606 - Highlights in Energy Research seminar series
Nanoparticles and their composite materials have attracted considerable interest during the last decades because of their optical, catalytic, mechanical and electrical properties, resulting in a wide range of applications. Avantama uses flame spray pyrolysis to produce its high quality powder, allowing the synthesis of precise and homogenous nanoparticles with virtually limitless chemical compositions. Furthermore, flame spray pyrolysis allows the rapid development of new materials and has proven its scalability up to the multi-ton scale.
To overcome the difficult usage of dry nanopowder in industrial processes, Avantama has developed a large know-how in formulation engineering. The formulation engineering is one of our core competencies, enabling us to help our customers to overcome tomorrow’s innovation challenges. The fine tuning of the formulation properties opens the door to the deposition of nanoparticles by roll-to-roll printing and thus allows the use of nanoparticles in applications requiring an efficient deposition method over a large area, as needed in printed electronics. Avantama formulations allow the coating of thin layers, for example such as the ones used in the production of organic photovoltaic devices.
In addition to creating nanoparticles by flame spray synthesis, we at Avantama also developed a novel approach to synthesizing Perovskite quantum dots on an industrial scale. Our proprietary production process yields the most efficient quantum dots at industrial scale.

The seminar can also be followed remotely by joining the online Cisco WebEx meeting (connection possible 15 minutes before the talk).

Terminal Antenna Design for Future Wireless

Buon Kiong Lau received the B.E. degree (with honors) from the University of Western Australia, Perth, Australia, and the Ph.D. degree from the Curtin University of Technology, Perth, Australia, in 1998 and 2003, respectively, both in electrical engineering. During 2000 to 2001, he was a Research Engineer with Ericsson Research, Kista, Sweden. From 2003 to 2004, he was a Guest Research Fellow at the Department of Signal Processing, Blekinge Institute of Technology, Sweden. Since 2004, he has been with the Department of Electrical and Information Technology, Lund University, where he is now a Professor in the Communications Group. He also holds a Senior Researcher appointment with the Swedish Research Council since 2010. He has been a Visiting Researcher with the Department of Applied Mathematics, Hong Kong Polytechnic University, China; the Laboratory for Information and Decision Systems, Massachusetts Institute of Technology, Cambridge, MA, USA; and the Takada Laboratory, Tokyo Institute of Technology, Japan.   Dr Lau's primary research interests are in various aspects of multiple antenna systems, particularly the interplay between antennas, propagation channels, and signal processing. He has co-authored 34 journal papers (17 in IEEE Transactions on Antennas and Propagation), 5 book chapters, over 100 conference papers and 3 patents/patent applications.   Dr. Lau has been an Associate Editor, a Senior Associate Editor and a Track Editor for the IEEE Transactions on Antennas and Propagation, for which he was also a Guest Editor of the “Special Issue on MIMO Technology” (2012) and the Lead Guest Editor of the “Special Issue on Theory and Applications of Characteristic Modes” (2016). In addition, he was the Lead Guest Editor of the “Special Cluster on Terminal Antenna Systems for 4G and Beyond” (2013) for the IEEE Antennas and Wireless Propagation Letters.   From 2007 to 2010, he was the Co-Chair of Subworking Group 2.2 on “Compact Antenna Systems for Terminals” within EU COST Action 2100. He has also served as a Swedish National Delegate and the Chair of Subworking Group 1.1 on “Antenna System Aspects” within COST IC1004 between 2001 and 2015. From 2012-2015, he was the elected Regional Delegate of European Association on Antennas and Propagation (EurAAP) for Region 6. He is also a member of the Education Committee within the IEEE Antennas and Propagation Society (AP-S), where he had been the Coordinator for the annual IEEE AP-S Student Design Contest during 2013-2015.   In 2015, Dr. Lau received an award from IEEE Transactions on Antennas and Propagation for exceptional performance as an Associate Editor (one of 3 awarded among 46 Associate Editors). His co-authored papers have received several Best Paper Awards, including two CST University Publication Awards in 2010 and 2013.  

Massive MIMO, full-dimension (FD) MIMO, millimeter-wave and small cells are some popular candidates for the 5th generation (5G) wireless communication systems. However, as much as these technologies present exciting new challenges for antenna design, the conventional design framework is expected to remain, partly due to the current emphasis on non-antenna issues. Conventionally, terminal antennas are designed based on simple, and often unrealistic criteria, including an emphasis on antenna performance in free space. Moreover, the need for compact multi-antenna implementation makes it even more challenging to deliver efficient antenna designs. Though poor antenna performance in reality is largely overlooked for different reasons, future wireless systems with high performance requirements will greatly benefit from a more comprehensive antenna design paradigm.
This lecture starts by giving an overview of conventional terminal antenna design and comment on its limitations. An outline  of the current trends in terminal antenna design for 4G systems is given. Then, a new antenna design paradigm that has the potential to dramatically improve 5G performance is introduced. In particular, the paradigm takes into account the interactions of the antenna system with its nearfield and farfield surroundings and provides a powerful framework to optimize these interactions. Finally, some practical techniques to take advantage of this design paradigm, where each technique offers promising performance gains over the state-of-the-art, are provided.

Some Recent Advances and Perspectives in Catastrophe Risk Engineering for Multiple Natural Hazards

Dr Carmine Galasso, Associate Professor of Catastrophe Risk Engineering in the University College London (UCL), UK

Abstract:
Probabilistic catastrophe (CAT) risk models are becoming increasingly popular tools for estimating potential loss due to natural hazards, including earthquakes, windstorms, and floods. Such models incorporate detailed databases and scientific understanding of the highly complex physical phenomena of natural hazards and engineering expertise about how infrastructure, buildings, and their contents respond to those hazards.
This talk will present some recent advances in CAT modelling for earthquake and wind, namely: 1) the use of physics-based and stochastic ground-motion simulations for seismic hazard and risk modelling; 2) the development of a real-time CAT modelling framework for designing engineering applications of earthquake early warning; 3) the development of computational tools (e.g., advanced simulations, machine-learning techniques) for modelling risk to offshore wind energy; 4) the proposal of a probabilistic framework to assess wind-seismic interaction in typical structural details (i.e., connections) of tall steel buildings.
The talk will finally introduce and discuss some perspectives in CAT modelling for cascading and multiple hazards at different spatial scales (from a single asset to portfolio of buildings), with special focus on developing countries. In fact, developing countries are disproportionately affected by natural hazards and lack in coping capacities. CAT modelling for developing countries presents specific challenges in terms of quantity and quality of the available input data. Specifically, this talk will present some highlights of a number of current UCL projects on multi-hazard risk and resilience assessment of community-based infrastructure (e.g., schools, hospitals, heritage assets) in the Philippines, Indonesia, and China.

ViTest - A rapid field-based diagnostic tool to detect grapevine diseases

2019 Igem team

ViTest is a fast point-of-care nucleic acid test to differentiate between two grapevine diseases: Flavescence Dorée and Bois Noir. Flavescence Dorée is infectious and needs to be quarantined quickly while Bois Noir is not. 

We start by extracting DNA from infected plant material using a microneedle patch. We then amplify the sequences corresponding to grapevine (endogenous control) and the diseases (if they are present). This step is performed using Recombinase Polymerase Amplification, an isothermal nucleic acid amplification method. The created amplicons are transcribed into mRNA and bind to a toehold sensor, thus activating a reporter gene.

Once this gene is translated, it produces catechol 2,3 dioxygenase which reacts with catechol and creates a colorimetric feedback. Both the transcription of the amplicons and the translation of the reporter gene are done in our homemade OnePot PURE cell-free system.

Abstract: Integrated  circuits are omnipresent. We not only use mobile phones, personal computers but we are surrounded by systems whose operation 
highly depends on advances sensors, processing systems, controllers etc.  such as  home appliances, cars, smart cards, smart energy systems, bio-medical  equipement, smart offices, transportation systems and many others. 
There are more and more new applications appearing in the picture with enormous data flows to deal with and process for our advantage.
One of these application areas is Artificial Intelligence (AI) and specifically Deep Learning in various domains of applications.
For these new envisaged applications we will need electronic systems with much improved, maybe 1000 times,  performance in terms of power consumption, speed of operation and reliability. Data transfer bottleneck, power consumption and scalability become major obstacles to be overcome.
As the sizing of transistors in current technologies comes to the atomic distance limitations further development becomes possible by either 
introduction of new disruptive technologies or changing in geometric arrangements and architectures of the elements and building blocks.
Some limitations in microcircuit constructions can be avoided by putting whole building blocks and sub-circuits in stacks. Such an approach allows for more efficient space usage at the same time allowing circuit footprint reduction. New routing solutions offer very significant wire-length reductions thus reducing power dissipations and signal delays.  
3D integration looks as a fantastic  area of development, however, there are many new challenges and problems to be solved for the next 
generation of nano systems. 3D integration offers also unprecedented opportunities by allowing blocks fabricated in heterogeneous
 technologies to be integrated in one chip. This allows for stacking and integration of microprocessors, memories, RF circuitry, sensors, 
batteries and hyper-capacitors, energy harvesting blocks,  biological and chemical sensors and many new types of building blocks in one chip. 
However innovation is needed for new developments.  AI acceleration requires still better solutions!
In this lecture we will present the state of-the-art and an outlook with commentaries what kind of new solutions might be needed.

IMX Seminar Series - Solutions of anionic 2D materials and phosphorene nanoribbons

Prof. Chris Howard, University College London UK

I will focus on recent work [1, 2, 3] in which we demonstrate that a range of ion-intercalated layered materials can spontaneously dissolve in polar solvents to form ionic solutions of 2D materials. The thermodynamically-driven dissolution is benign, advantageously maintains the morphology of the starting materials and can achieve solutions containing exclusively individualised monolayers. The charge on the anionic nanosheet solutes is reversible, enables targeted deposition over large areas via electroplating and can initiate novel self-assembly upon drying [1].
Surprisingly, applying this method to crystals of black phosphorus results in nanoribbons rather than 2D nanosheets [2]. Despite the motivation of over 100 publications predicting that phosphorene nanoribbons (PNRs) would have extraordinary properties, until our work, no one had made PNRs, and there was no obvious way of applying established routes for forming graphene nanoribbons to phosphorene. The PNRs we produce have typical widths of 4-50 nm, predominantly single-layer thickness, lengths up to 75 μm. The PNRs are atomically-flat single crystals, aligned exclusively in the zigzag crystallographic orientation with remarkably uniform widths along their entire lengths, and are extremely flexible. Our work thus enables the search for predicted exotic states in PNRs including spin density waves, tunable magnetism and topological states, and testing in applications where PNRs are predicted to give transformative advantages, ranging from fast-charging batteries, to flexible thermoelectric devices and nanoelectronics.

IGM Colloquium: The role of added mass and circulatory forces in unsteady incompressible flows

Prof. Holger Babinsky, Engineering Department, University of Cambridge

Abstract:
Unsteady effects occur in many natural and technical flows, for example flapping wings or air vehicle gust encounters. If the accelerations are large the resulting unsteady forces can be quite considerable, a fact that is exploited by insects and small birds to generate additional lift at low Reynolds numbers. However, the exact physical mechanisms underlying the generation of unsteady force continue to challenge our understanding of such flows. One approach to improve our insight is to identify the dominant effects and describe these with low-order force models. An often-made classification is to group forces into circulatory (e.g. vortex lift or bound circulation) and non-circulatory (added-mass).
 
Although the concept of added mass has been around for more than a century and is superficially simple, its details continue to confound and confuse. In this talk I will re-visit the definition of added mass and propose a different interpretation. Using a series of simple, canonical, experiments and PIV I will show how the contributions made by different physical force mechanisms can be identified experimentally and thus clarify some open questions about this concept.

"Leader Emergence in Nascent Venture Teams: The Critical Roles of Individual Emotion Regulation and Team Emotions"

Résumé

This study advances a theory of how different aspects of emotion regulation influence individual leader emergence in the intensely emotional context of nascent venture teams. Despite the growing amount of research on the role of leadership in the entrepreneurial process, the emergence of leaders in nascent venture teams has rarely been explored. Drawing on theories and research on leadership emergence and emotion regulation, we argue that the two aspects of emotion regulation (i.e., reappraisal and suppression) exert opposite effects on the degree to which nascent venture team members come to perceive an individual as a leader. We also theorize that team emotions arising from affective events moderate the relationship between reappraisal and leader emergence in such teams. Data from 103 nascent venture teams without prior leaders show a negative relationship between individuals’ trait disposition to suppress emotions and their emergence as leaders, and a positive relationship between their trait disposition to reappraise emotions and their emergence as leaders. Moreover, we find that negative team emotions magnify the positive association between reappraisal and leader emergence, while positive team emotions mitigate it.
We discuss the implications of our findings for the literature on entrepreneurial leadership, entrepreneurial emotions, and leadership in general.

Two-Dimensional Colloidal Quantum Wells for Future Photonic Sources

Prof. Chih-Jen SHIH
Department of Chemistry and Applied Biosciences
ETH Zurich

ChE-606 - Highlights in Energy Research seminar series
Miniaturized photonic sources based on semiconducting two-dimensional (2D) materials offer new technological opportunities beyond the modern III-V platforms. For example, the quantum-confined 2D electronic structure aligns the exciton transition dipole moment, directing emission perpendicular to the surface which gives rise to high-efficiency quantum optics and electroluminescent devices. It requires scalable materials and processes to create the decoupled multi-quantum-well (MQW) superlattices, in which individual 2D material layers are isolated by atomically thin quantum barriers (QBs). My research group developed synthetic routes to obtain monodispersed, quantum-confined colloidal quantum wells (CQWs) of lead halide perovskites with precise thickness control, yielding different emission colors without altering the chemical composition. We successfully developed the protocols fabricating the thin-film MQW superlattices out of these materials. Unexpectedly, an enhancement of PLQY with respect to colloidal dispersions was observed, and individual QWs can be decoupled with unprecedentedly ultrathin QBs that screen interlayer interactions within the range of 6.5 Å. These unique phenomena were investigated in order to uncover the underlying physical mechanisms. The photonic sources demonstrated here have narrowband emission together with high quantum yield, directionality, and wavelength tunability, which are highly desirable for many near-field and far-field applications such as nanoantennas and light-emitting diodes.

The seminar can also be followed remotely by joining the online Cisco WebEx meeting (connection possible 15 minutes before the talk).

Enabling Continuous Learning through Synaptic Plasticity in Hardware

Tushar Krishna, Assistant Professor in the School of Electrical and Computer Engineering at Georgia Tech.

Ever since modern computers were invented, the dream of creating artificial intelligence (AI) has captivated humanity. We are fortunate to live in an era when, thanks to deep learning (DL), computer programs have paralleled, and in many cases even surpassed human level accuracy in tasks like visual perception and speech synthesis. However, we are still far away from realizing general-purpose AI. The problem lies in the fact that the development of supervised learning based DL solutions today is mostly open loop.  A typical DL model is created by hand-tuning the deep neural network (DNN) topology by a team of experts over multiple iterations, followed by training over petabytes of labeled data. Once trained, the DNN provides high accuracy for the task at hand; if the task changes, however, the DNN model needs to be re-designed and re-trained before it can be deployed. A general-purpose AI system, in contrast, needs to have the ability to constantly interact with the environment and learn by adding and removing connections within the DNN autonomously, just like our brain does. This is known as synaptic plasticity.

In this talk, we will present our research efforts towards enabling general-purpose AI leveraging plasticity in both the algorithm and hardware. First, we will present GeneSys (MICRO 2018), a HW-SW prototype of a closed loop learning system for continuously evolving the structure and weights of a DNN for the task at hand using genetic algorithms, providing 100-10000x higher performance and energy-efficiency over state-of-the-art embedded and desktop CPU and GPU systems. Next, we will present a DNN accelerator substrate called MAERI (ASPLOS 2018), built using light-weight, non-blocking, reconfigurable interconnects, that supports efficient mapping of regular and irregular DNNs with arbitrary dataflows, providing ~100% utilization of all compute units, resulting in 3X speedup and energy-efficiency over our prior work Eyeriss (ISSCC 2016). Finally, time permitting, we will describe our research in enabling rapid design-space exploration and prototyping of hardware accelerators using our dataflow DSL + cost-model called MAESTRO (MICRO 2019).

Abstract: Whereas human tissues and organs are mostly soft, wet and bioactive; machines are commonly hard, dry and biologically inert. Merging humans, machines and their intelligence is of imminent importance in addressing grand societal challenges in health, sustainability, security, education and joy of living. However, interfacing humans and machines is extremely challenging due to their fundamentally contradictory properties. At MIT Zhao Lab, we exploit soft materials technology to form long-term, high-efficacy, multi-modal interfaces and convergence between humans and machines.  In this talk, I will first discuss the mechanics to design extreme properties including tough, resilient, adhesive, strong, fatigue-resistant and conductive for hydrogels, which are ideal material candidates for human-machine interfaces. Then I will discuss a set of soft materials technology platforms, including i). bioadhesives for instant strong adhesion of diverse wet dynamic tissues and machines; ii). bioelectronics for long-term multi-modal neural interfaces; iii). biorobots for teleoperated and autonomous navigations and operations in previously inaccessible lesions such as in cerebral and coronary arteries. I will conclude the talk with a perspective on future human-machine convergence enabled by soft materials technology.

Defining mitochondrial protein function through systems biochemistry

David J. Pagliarini 1, 2         (1, Morgridge Institute for Research, Madison, WI 53715, USA - 2, Department of Biochemistry, University of Wisconsin–Madison, Madison, WI 53706, USA)

Despite their position as the iconic powerhouses of cellular biology, many aspects of mitochondria remain remarkably obscure—a fact that contributes to our poor ability to address mitochondrial dysfunction therapeutically. Such dysfunction contributes to a vast array of human diseases through distinct means. For instance, aberrant mitochondrial biogenesis can fail to properly set cellular mitochondrial content; dysregulated signaling processes can fail to calibrate mitochondrial activity to changing cellular needs; and malfunctioning proteins can render core bioenergetic processes ineffectual. A major bottleneck to understanding—and ultimately addressing—these processes is that the proteins driving them are often undefined. Concurrently, the functions of hundreds of mitochondrial proteins that may fulfill these roles are not known, or at best are poorly understood. The high-level goal of my research program is to help achieve a more complete, systems-level understanding of mitochondrial biology by systematically establishing the functions of orphan mitochondrial proteins and their roles within disease-related processes. We do so by first devising multi-dimensional analyses designed to make new connections between these proteins and established pathways and processes. We then employ mechanistic and structural approaches to define the functions of select proteins at biochemical depth. This ‘systems biochemistry’ strategy is helping us address three outstanding biological questions: Which orphan mitochondrial proteins fulfill the missing steps in classic mitochondrial processes, including the biosynthesis of coenzyme Q and other aspects of respiratory chain function? What proteins assist in the orchestrated assembly of lipids, metabolites, and proteins (from two genomes) to ensure proper mitochondrial biogenesis? And, which resident signaling proteins direct the post-translational regulation of mitochondrial activities? In answering these questions, we aim to help transform the mitochondrial proteome from a component list into a metabolic circuitry of connected functions, and to elucidate the biochemical underpinnings of mitochondrial dysfunction in human disease.

Polymeric modules for synthetic biology

Prof. Katharina Landfester 

Since many years, there is a quest for minimal cells in the field of synthetic biology, potentially allowing a maximum of efficien­cy in biotechnological processes. Although the so-called “protocells” are usually referred to in all papers that attempt a cumulative definition of Synthetic Biology, research in this area has been largely under-represented. The aim of the Landfester lab is to develop vesicular structures, i.e. protocells, based on block copolymer self-assembly and engulfed nanocontainers with incorporated functions, such as energy production and the control of transport properties through nanomembranes. They have designed and developed nanocapsules that act as cell-like compartments and can be loaded with enzymes for synthetic biology and chemistry. In addition, self-assembly of well-defined diblock copolymers has been used to generate polymersomes and hybrid liposomes/polymersomes. Both strategies allow the compartimentalization on the nano- or microscale and conducting enzymatic or chemical reactions in the confinement of the polymersomes/ nanocarriers. New block copolymers and permeable nanocarriers have been synthesized and optimized. With these protocols, the Landfester lab established an enzymatic reaction cascade within droplet-based compartments. These compartments can act as cell-like functions to regenerate NAD. For these tasks, novel conductive polymer nanoparticles have been developed which will be included into the protocells for the NAD regeneration by light. Also enzyme-complexes are assembled that will fulfill these requirements.

Katharina Landfester received her doctoral degree in Physical Chemistry after working in 1995 at the Max Planck Institute for Polymer Research (MPIP). After a postdoctoral stay at the Lehigh University (Bethlehem, PA), she worked at the Max Planck Institute of Colloids and Interfaces in Potsdam (Germany) leading the mini-emulsion group. From 2003 to 2008, she was full professor at the University of Ulm. At the MPIP, she started her activities in the field of biomedical applications in cooperation with several medical groups working on the interaction of nanoparticles with different cell compartments, the labelling of cells and the delivery of substances to specific sides. She joined the Max Planck Society in 2008 as one of the directors of the MPIP. She was awarded the Reimund Stadler prize of the German Chemical Society and the prize of the Dr. Hermann Schnell Foundation, followed by the Bruno Werdelmann Lecturer in 2012 and the Bayer Lecturer in 2014. Her research focusses on creating functional colloids for new material and biomaterial applications. She has published more than 650 papers in international journals, 30 reviews and holds more than 50 patents.

IGM Colloquium: Some new directions in particle flow modeling

Prof. Ken Kamrin, Department of Mechanical Engineering, Massachusetts Institute of Technology (MIT)

Abstract:
This talk discusses developments in continuum modeling and hybridized discrete-continuum modeling for fluid-saturated and dry granular flows.  First we discuss a methodology for simulating "simple" continuum models for dry grains, focusing on a recent frictional plasticity model and a meshfree simulation approach using the Material Point Method (MPM).This approach on its own is shown sufficient to describe a number of granular intrusion problems.

However, due to its simplicity such a model cannot always be trusted to capture general flows accurately, nor represent particle-scale phenomena such as clogging, bouncing, and ballistic motion. To address this we propose a discrete-continuum hybrid approach, where an "oracle" algorithm dynamically partitions the domain into continuum MPM regions, where continuum modeling is safe, and discrete element regions where necessary. The domains overlap along transition zones, where a Lagrangian dynamics mass-splitting coupling principle enforces agreement between the two simulation states. Enrichment and homogenization operations allow the partitions to evolve over time. This approach accurately and efficiently simulates scenarios that previously required an entirely discrete treatment.

Finally, we discuss a technique for submerged granular flow problems, which treats the granular phase and the fluid phase as two separate, yet coupled continuum models. Using mixture theory, bouyancy and drag forces couple the Navier-Stokes behavior of the fluid phase to a dilatant, rate-sensitive granular flow model.  We run this mixture formulation using two coupled MPM simulations, one for the fluid phase and one for the granular phase, which solves for all continuum variables in all phases.  This methodology is shown able to replicate experimental results for saturated granular flows over a range of conditions and dilutions, and can be extended to account for more obscure effects, such as those giving rise to shear-thickening suspensions.

Tech Apero – Smart Fibers for Wearable Sensors and Drug Delivery

René Rossi (Empa), Fabien Sorin (EPFL), Alexander Schaetz (Syngenta) and Siegfried Winkelbeiner (Schoeller)

Fibers and textiles are the only materials perennially in constant contact with our bodies. With the Internet of Things, clothes have become intelligent materials able to support the wearer, for instance as devices for medical assistance. Through consortia involving the major textile companies in Switzerland and academic research sponsored by the CCMX, new insights into fiber science are leading to the development of advanced technologies that allow wearable textiles to sense, monitor and respond to physiological or environmental changes.

Over the course of this Technology Apéro, the scientists leading the CCMX project, René Rossi and Fabien Sorin, will present novel fiber technologies based on electrospinning and thermal drawing, for on demand drug delivery and monitoring of specific metabolites. Moreover, Schoeller and Syngenta will present R&D developments, giving us an insight into the future of commercial textiles.

This event will be a perfect opportunity for you to discuss with industrial leaders and academics at the forefront of fiber research and development. The informal aperitif, offered after the talks, is an occasion to meet the speakers and explore opportunities for collaboration. Please join us!

Quantitative Time-Resolved Dissection of Gene Expression and Cell Identity

Prof. David Suter, Institute of Bioengineering, EPFL (CH)

Abstract:
The genome contains the building plan of living organisms and largely determines their phenotype. Within complex multicellular animals, the differential activity of a common set of genes allows generating a large diversity of cell types. However, the activity of individual genes displays large temporal fluctuations, and mechanisms of gene regulation are disrupted when cells enter into mitosis. How these perturbations impact the control of cell identity is not understood.
My laboratory develops new approaches to dissect gene expression and cell fate decisions in a quantitative and time-resolved manner. I will first describe our quantifications of transcription factor-DNA interactions, the memory of gene activity through cell generations, and the coordination of protein synthesis and degradation in single living cells. I will then discuss how temporal fluctuations of transcription factor levels and their activity across the cell cycle impact self-renewal and differentiation of embryonic stem cells. Our work illustrates how quantitative time-resolved analysis of gene expression allows deepening our understanding of cell identity control.

Short bio:
David Suter obtained his MD/PhD at the University of Geneva on stem cell biology, followed by a first postdoctoral training with Ueli Schibler focusing on single cell monitoring of transcription.

Brainhack Global Geneva 2019

Three speakers during the event

Are you interested in collaborating on innovative brain-related projects during Brainhack at Campus Biotech in Geneva?

Brainhack is a 2 ½ day hackathon on brain technologies, mostly brain imaging but not only. It will take place on November Friday 8th and Saturday 9th, with a presentation of all the projects and a get together the day before on Thursday 7th at 5pm (cf full program here). 

To participate, you don’t need to know anything specific about the brain, just to bring yours! We welcome anyone from coders to doctors. Projects we just started collecting range from machine learning to identify brain states, via generating music from MRI signals, to developing a multiplayer game reading brain signals.

Contrarily to traditional hackathons during which teams compete, brainhacks are collaborative: all teams work on different projects and we’ll have more than a half-dozen for you to choose from. Project proposals just started being collected so right now you could attend the event in two ways:
  • as a participant to have fun on any project you’ll see presented during the pitches on Thursday: to do this please register here

EE Distinguished Speakers Seminar: Towards a power electronics based power systems

Antonello Monti received his M.Sc degree (summa cum laude) and his PhD in Electrical Engineering from Politecnico di Milano, Italy in 1989 and 1994 respectively.  He started his career in Ansaldo Industria and then moved in 1995 to Politecnico di Milano as Assistant Professor.  In 2000 he joined the Department of Electrical Engineering of the University of South Carolina (USA) as Associate and then Full Professor.  Since 2008 he is the director of the Institute for Automation of Complex Power System within the E.ON Energy Research Center at RWTH Aachen University. Dr. Monti is author or co-author of more than 300 peer-reviewed papers published in international Journals and in the proceedings of International conferences. He is a Senior Member of IEEE, Associate Editor of the IEEE System Journal, Associate Editor of IEEE Electrification Magazine, Member of the Editorial Board of the Elsevier Journal SEGAN and member of the founding board of the Springer Journal “Energy Informatics”. Dr. Monti is the recipient of the 2017 IEEE Innovation in Societal Infrastructure Award

Abstract: The energy transformation is bringing more and more power electronics into the power system. As result, we are moving from a classical electromechanical system to a fully electronic driven system. This change is significantly affecting the dynamics of the power system but also opening completely new opportunities. The presentation will discuss challenges and opportunities opened by this transformation. The main conclusion is that it is more an opportunity than a problem even if a lot of research is still needed to reach the definition of a full concept of automation for future power systems. At the same time, thanks to the experience earned in several projects, interesting options are emerging showing how the future power electronics-based power system could be actually more reliable than the classical power system.

IMX Seminar Series - Cellulose Nanofibrils: from Single Particle Structure to Multiscale Material Assembly

Dr Gustav Nystrom, EMPA Switzerland

The increasing global population and improved living standards demand a more efficient use of available resources and energy, and it is therefore critical to improve the use of sustainable resources without sacrificing the quality of materials and products. Cellulose nanofibrils from wood represents an important class of sustainable biocolloids with great promise for use in high performance nanomaterials due to their high specific strength and stiffness, chemical resilience and self-organizing behavior. Optimal use of nanocellulose in new materials, however, requires control of both the individual particle structure as well as how the particles are assembled over several length scales. Our fundamental work in this area is dedicated to an understanding of the single particle structure and properties, and how this structural knowledge can be used to understand and predict the controlled formation of higher order structures that ultimately lead to materials with optimized functionality. We use high-resolution microscopy to elucidate the physical properties of nanocellulose particles, follow their liquid crystal assembly in the light microscope, use physical scaling arguments to understand the different phases that are formed and combine this knowledge with external structuring techniques to form functional nanocellulose materials. In this overview presentation, I will describe our multiscale research approach specifically highlighting the nanoscale features of the cellulose nanofibrils and also give examples of how these particles can be used to produce functional materials in the form of gels, foams and 3D printed materials with integrated functionalities.
Bio: Gustav Nyström received his PhD in Engineering Physics from Uppsala University in 2012. Following postdoctoral work at KTH Royal Institute of Technology (Stockholm) with Lars Wågberg and Lars Berglund in the Wallenberg Wood Science Center and at ETH Zurich with Raffaele Mezzenga, he is since 2018 head of the Cellulose & Wood Materials laboratory at Empa and a Lecturer at ETH Zurich. He was the recipient of the Gunnar Sundblad Research Foundation’s Skills Development Prize (2014) and is a Swiss National Science Foundation Ambizione Fellow (2016). His research focuses on the interactions between polymers, nanoparticles, and colloids from renewable resources with the aim of finding energy efficient routes to build high performance materials contributing to a sustainable future.

IMX Seminar Series - Enhanced sampling of atomistic processes during structural phase transformations

Dr Jutta Rogal, Ruhr University Bochum Germany

Obtaining atomistic insight into the fundamental processes during structural phase transformations and their dynamical evolution up to experimental timescales remains one of the great challenges in materials modelling. In particular, if the mechanisms of the phase transformations are governed by so-called rare events, the timescales of interest will reach far beyond the applicability of regular molecular dynamics simulations. In addition to the timescale problem the simulations provide a vast amount of data within the high-dimensional phase space. A meaningful physical interpretation of these data requires the projection into a low-dimensional space and the identification of suitable reaction coordinates.

In this presentation, I will give an overview of our recent progress in the application of advanced atomistic simulation techniques to capture the dynamical behaviour during phase transformations over a large range of timescales. One of the key results is the analysis of nucleation and growth mechanisms during solidification in metals that can be extracted from transition path sampling simulations. By applying a likelihood maximisation scheme the quality of different reaction coordinates is evaluated which enables us to identify the most important order parameters that characterise the atomistic processes during the initial stages of nucleation and growth.
A second example is the analysis of phase boundary migration during solid-solid transformations in metals between two different crystal structures with semi-coherent interfaces. The transformation proceeds via a collective displacement of atoms in the interface region. The associated effective energy barrier that determines the mobility of the phase boundary results from the characteristic features of the complex energy landscape that the system explores during the transformation.

Bio: Jutta Rogal received her PhD from the Freie Universität Berlin in 2006, carrying out her PhD work on electronic structure calculations for surface catalysis at the Fritz Haber-Institute of the Max Planck Society. For her PhD thesis she was awarded the Otto Hahn Medal of the Max Planck Society and the Ernst-Reuter Preis of the Freie Universität Berlin. In 2007 Dr. Rogal moved to the University of Amsterdam as a postdoctoral researcher to develop methodological extensions to the transition path sampling approach. Since 2009 she is a research group leader at Interdisciplinary Centre for Advanced Materials Simulations (ICAMS) at the Ruhr University Bochum.  Her group focusses on the development and application of advanced atomistic simulation technique to capture the dynamical behaviour of materials on extended timescales.  This includes the investigation of phenomena related to phase transformations such as diffusion, nucleation, and growth. In 2016 Dr. Rogal was awarded a Feodor Lynen Research Fellowship of the Alexander von Humboldt Foundation which she spent at New York University in 2017/18 working on enhanced sampling techniques for high dimensional energy landscapes.

CESS Seminar - Recruiting structural optimization to the seismic design process

Dr. Oren Lavan, Associate Professor, Technion Israel Institute of Technology

Abstract:
Over the past three decades, there has been a significant shift in the approach to structural design under dynamic loadings. Many new technologies associated with passive energy dissipation and control have been introduced and have reached a considerable level of maturity. Furthermore, the concept of performance-based design and financial loss considerations have gained prominence. While all of this represents a major step forward, as a consequence, the design process itself has become increasingly complex.
The aim of this talk is to discuss the potential role of structural optimization in the seismic design process. This will be done while presenting ongoing research in which the presenter has been involved. The research is focused on various optimal design methodologies using various types of energy dissipation devices. Particular attention is given to the importance of a meaningful optimization problem formulation, the value expected from utilizing optimization, the importance of tailoring an appropriate optimization algorithm for a given problem, and the potential of using optimization in practical design.

Bio:
Dr. Oren Lavan is an Associate Professor in the Faculty of Civil and Environmental Engineering at the Technion – Israel Institute of Technology. He received his Ph.D. in Civil Engineering from the Technion in 2006, and was a Visiting Research Scientist (2005-2007) at the Department of Civil, Structural and Environmental Engineering, University at Buffalo – The State University of New York.

Shedding Light on Ciliary cAMP Signaling

Prof. Dagmar Wachten, University of Bonn (D)

WEEKLY BIOENGINEERING COLLOQUIA SERIES
(sandwiches served)

Abstract:
Primary cilia are cellular antennae, orchestrating signal transduction in most mammalian cells. Cilia dysfunction leads to the development of severe human diseases, collectively termed ciliopathies. However, the underlying molecular mechanisms are ill-defined. Cilia constitute a unique subcellular compartment. A diffusion barrier and the ciliary transport machinery maintain a protein composition that is distinct from the cell body. Although cAMP signaling components are enriched in the cilium, the role of ciliary cAMP signaling remains enigmatic. We have developed approaches that allows to specifically analyze cAMP signaling in motile and non-motile cilia using optogenetics and, thereby, shed light on ciliary signaling.

IMX Seminar Series - Amyloid Fibrils: Once Pathological Agents, Today Building Blocks for the Future

Prof. Raffaele Mezzenga,ETH Zurich Switzerland

Protein fibrils are protein aggregates, which can be generated from food-grade proteins by unfolding and hydrolysis. The resulting protein fibrils can be used in a broad context of applications. At length scales above the well-established atomistic fingerprint of amyloid fibrils, these colloidal aggregates exhibit mesoscopic properties comparable to those of natural polyelectrolytes, yet with persistence lengths several orders of magnitude beyond the Debye length. This intrinsic rigidity, together with their chiral, polar and charged nature, provides these systems with some unique physical behavior. In this talk I will discuss our current understanding on the mesoscopic properties of amyloid fibrils at the single molecule level, the implication of their semiflexible nature on their liquid crystalline properties, and I will illustrate how this information prove useful in understanding their collective behavior in bulk and when adsorbed at liquid interfaces. By the careful exploitation of the physical properties of amyloid fibrils, the design of advanced materials with unprecedented physical properties become possible, and I will give a few examples on how these systems can ideally suit the design not only of complex food systems, but also of biosensors and biomaterials, catalytic and water purification membranes.

Bio: Raffaele Mezzenga received his PhD from EPFL Lausanne in 2001 and spent 2001-2002 as a postdoctoral scientist at University of California, Santa Barbara, working on the self-assembly of polymer colloids. In 2003 he moved to the Nestlé Research Center in Lausanne as research scientist, working on the self-assembly of surfactants, natural amphiphiles and lyotropic liquid crystals. In 2005 he was hired as Associate Professor in the Physics Department of the University of Fribourg, and he then joined ETH Zurich on 2009 as Full Professor. His research focuses on the fundamental understanding of self-assembly processes in polymers, lyotropic liquid crystals, food and biological colloidal systems. Prof. Mezzenga has been recipient of several national and international distinctions such as the 2011 AOCS Young Scientist Research Award, the 2013 Dillon Medal and the 2017 Fellowship of the American Physical Society, the Biomacromolecules/Macromolecules 2013 Young Investigator Award of the American Chemical Society, the 2004 Swiss Science National Foundation Professorship Award and the 2019 Spark Award for the most innovative 2019 ETH invention.

IGM Colloquium: Nano-optics gets practical

Prof. Romain Guidant, Institute of Photonic Sciences (ICFO)

Abstract:
Twenty years of extensive research in the field of nanooptics have enabled us to considerably advance light control on the nanometer scale. Beyond the original peak of inflated expectation, the assets of nanooptics over other technologies became clearer along with its limitations. More recently, the field has entered into the slope of enlightenment in which its actual contribution to both basic research and novel technologies has been better identified. In this talk, following a general introduction on the main assets of nano-optics, we will review different aspects of our research where nano-optical resonators are used as an enabling technology that can benefit a wide range of scientific disciplines, all the way from reconfigurable planar optics to biomedicine.
The first part of the talk focuses on our recent efforts towards reconfigurable metasurfaces. Our approach relies on dynamically controlling the refractive index in the close vicinity of a silicon metalens by means of a resistor embedded in a thermo-optical polymer. We demonstrate precise and continuous tuneability of the focal length, and achieve focal length variations larger than the Rayleigh length for voltage as low as 10V and time-response in the 10ms range. We also demonstrate that by solving the inverse problem, we are able to deterministically achieve any desired phase front. In the second part of the talk, we discuss the use of both dielectric and metallic nanoresonators in the context of biosensing and lab-on-a-chip technology. The sensors are integrated into a state-of-the-art PDMS microfluidic environment and their surface functionalized to achieve specific detection of the targeted biomarkers. We directly compare the performance of gold and silicon nanosensors and discuss their respective advantages. Finally, we discuss our latest advances in the field of thermoplasmonics, presenting two new application in additive manufacturing (3D printing) and disinfection of surgical implants.
 
Bio:
I received a PhD in Physics (2002) from the University of Dijon, in France. Right after defending my thesis, I joined ICFO as a postdoctoral researcher. This was the year of its creation and I was lucky enough to get actively involved into the early developments of the Institute. In 2006, I was appointed junior Professor (tenure-track) and group leader of the Plasmon NanoOptics group at ICFO. In 2009, I became tenure Professor both at ICFO and ICREA. While my core expertise is in fundamental nano-optics, I am very much interested in multidisciplinary research, interfacing physics with other disciplines of science, as well as in technology transfer. I am recipient of 4 ERC grants (StG2010, PoC2011, PoC2015 and CoG2015) and several international and national prizes (Fresnel2009, City of BCN2010, ICO2012, CAT2014, BS2017).

IMX Seminar Series - Microsonics for communication and sensors

Prof. Paul Muralt, EPFL Switzerland

Microsonics has emerged as field in microsystems technology dealing with ultrasonic applications. Considering that typical sound velocities in solids are ranging from 4’000 to 10’000 m/s we conclude that a wavelength of a micrometer corresponds to frequencies of 4 to 10 GHz. This means that mechanical resonators with micrometer dimensions resonate in the lower GHz frequency range, the same range as the transmission bands of mobile telecommunication (between 0.4 and 3 GHz). Of course, we need a link between wireless transmission based on electromagnetic waves, and the ultrasonic waves in microsonic devices. The required transformation is provided by piezoelectric materials, either as single crystal or as thin film. Modern mobile communication owes its existence indeed to piezoelectric materials, because only electromechanical resonances in selected piezoelectrics yield high enough quality factors within reasonably small dimensions.
This talk focuses on piezoelectric thin film resonators, which in the simplest configuration are just thickness mode vibrators. We note again that a typical thin film thickness fits well the required half-wavelength thickness for communication bands in the lower GHz frequency bands. Microsonics developed in parallel to mainstream MEMS technology, focusing on integrating piezoelectric films, and improving dimensional precision. There are of course very high requirements as to the quality and stability of such films. The best material found so far is AlN, having a correct size of piezoelectric coupling, a large mechanical quality factor, and also a good thermal conductivity, which is important for filters in the transmit line to support the power in the sending mode. With the discovery of the extraordinary increase of piezoelectricity when alloying non-piezoelectric ScN into AlN by a Japanese group, the field got a new thrill. The larger piezoelectric coupling allows for larger communication bands, satisfying better the ever-increasing need for higher bit rates.  Moreover, other types of resonators having inherently lower coupling factors than the simple devices exploiting longitudinal bulk waves become now also interesting.
The talk will address some growth and microstructural issues in Al(1-x)ScxN thin films. The piezoelectric wurtzite phase is in fact a metastable phase, and its growth in a polarly oriented microstructure at relatively low temperatures (300 °C) is a typical achievement of sputter deposition. Nevertheless, there is a certain risk to obtain misaligned grains that are thought to be caused by secondary nucleation of ScN rich, nanometer sized rocksalt within grain boundaries at the surface of the growing wurtzite film. On the acoustic side we shall speak about a breakthrough in Lamb wave devices, for which a larger quality factor was achieved when having the wave-carrying plate not freely supported, but isolated by an acoustic Bragg mirror structure. Finally, another novel device is presented, a 3D machined micro transducer that couples bulk waves generated in periodic pillars into a surface wave that is travelling away on the substrate surface. When combined with a reflector grid at some distance, the wave comes back into the transducer and is detected as echo. Knowing the temperature coefficient of the surface wave, the travelling time reveals the temperature of the device. A wireless coupling between transducer and an antenna enables then a wireless temperature readout up to 600 °C in experiment, with prospects to reach 800 °C.

IGM Colloquium: Buffering by buckling: New wrinkles on Gauss’ Pizza Theorem

Prof. Dominic Vella, Mathematical Institute, University of Oxford

Abstract:
The deformations of thin elastic objects are familiar from everyday life, from a piece of paper or clothes crumpling, to vibrations of bridges and other structures. A guiding principle of such deformations is that the material chooses to bend, rather than change its length, whenever possible. I will describe some of the consequences of this desire to avoid stretching and Gauss’ Remarkable Theorem, which include everyday examples like the geometrical rigidification of pizza slices by curving the crust. However, I will show that these consequences can be subverted by buckling instabilities such as wrinkling. Finally, I will talk about how fast these deformations happen.

Hydrogel-based Electronics: Ultracompliant electrodes for neural interfaces and beyond

Prof Christopher J Bettinger, Carnegie Mellon University, USA.

Implantable neural interfaces underpin many technologies that rely on recording and stimulating neuronal activity from organs in the central and peripheral nervous systems. Reliable and stable chronic recording from excitable tissues using implantable multielectrode arrays has been elusive to date due, in part, to host tissue interactions that contribute to device failure. Local tissue damage and device failure is worsened by the mechanical mismatch between materials used to fabricated rigid silicon-based microfabricated multielectrode arrays (EMEA ~ 100 GPa) and tissues in the nervous system (EPNS ~ 10 kPa). Hydrogel-based electronics could reduce the mechanical mismatch across the tissue-device interface and enhance performance. Here we present materials and companion fabrication strategies to create ultracompliant electronic devices for use in peripheral nerve interfaces. Integrated strategies for polymer synthesis, processing, and microfabrication are described. Details regarding the in vitro and in vivo performance of these devices will also be presented.

IMX Seminar Series - Ultimately sensitive organic bioelectronic transistor sensors

Prof. Luisa Torsi, University of Bari Italy

Organic bioelectronic sensors are gaining momentum as they can combine high performance sensing level with flexible large-area processable materials. This opens to potentially highly performing biomarkers sensing systems for point-of-care health monitoring at low-cost. Prominent to detect biochemical recognition events are the Electrolyte-Gated Organic Field-Effect Transistors that have been recently shown capable of label-free single-molecule detections, even in blood serum.
Indeed, Label-free single-molecule detection has been achieved so far by funneling a large number of analyte molecules into a sequence of single-binding events with few recognition elements host on nanometric transducers. Such approaches are inherently unable to sense a cue in a bulk milieu. Conceptualizing cells’ ability to sense at the physical limit by means of a transducing interface comprising highly-packed recognition elements, a millimetric sized electrolyte-gated field-effect-transistor is used to detect a single molecule. To this end, the gate is bio-functionalized with a self-assembled-monolayer of trillions of capturing antibodies, endowed with a hydrogen-bonding network enabling cooperative-interactions. The selective and label-free single-molecule detection is strikingly demonstrated in diluted saliva while few tens of antigens are assayed in whole serum. The suggested sensing mechanism triggered by the affinity binding event, involves a work-function change that is assumed to propagate in the gating-field through the electrostatic hydrogen-bonding network. The proposed immunoassay platform is general and can revolutionize the current approach to protein detection.

Non-invasive brain stimulation and neurofeedback: from basic research to decoding motor intentions

Prof. Nici Wenderoth, ETH Zurich, CH.

Operant conditioning based on neurofeedback is increasingly used in both basic research and neurorehabilitation. Electroencephalography (EEG) is likely the most popular non-invasive modality for neurofeedback in humans, but applications are challenged by a low signal-to-noise ratio and poor anatomical and functional specificity. Here I will present an alternative approach where we apply transcranial magnetic stimulation (TMS) in a non-invasive neurofeedback context. I will show (i) that healthy participants can learn to volitionally up- or down-regulate the state of their motor system and elucidate which neurophysiological mechanisms mediate this effect; (ii) how this approach can be extended to decoding intended finger and hand movements; and (iii) that TMS neurofeedback training is feasible in stroke patients. 

Bio. Professor Nici Wenderoth is full professor for Neural Control of Movement in the Department for Health Sciences and Technology at ETH Zurich, Switzerland. Her main research focus is on human systems neuroscience. Additionally, she actively pursues translational research in animal models and clinical applications. She is currently Director of the Institute of Human Movement Sciences and Sport, Director of the interdisciplinary Future Health Technologies research programme at the Singapore-ETH Campus and President of the Betty and David Koetser Foundation for Brain Research.

Development of a Cortical Visual Neuroprosthesis for the blind

Prof. Eduardo Fernandez, University Miguel Hernandez and CIBER BBN, SP.

Cortical prostheses are a subgroup of visual neuroprostheses capable of evoking visual percepts in profoundly blind people through direct electrical stimulation of the occipital cortex. This approach may be the only treatment available for blindness caused by glaucoma, end-stage retinal degenerations, optic atrophy or trauma to the retina and/or optic nerves. However, there are still a relevant number of open questions and more experiments should be done to achieve the clinical goals envisioned by this new technology.
We are now facing the challenge of creating a cortical visual neuroprosthesis, based on intracortical microelectrodes, which could allow to provide a limited but useful visual sense to profoundly blind.  We will introduce preliminary results of electrical stimulation of human visual areas and review some of the principles and difficulties related to the development of a cortical visual neuroprosthesis for the blind using intracortical microelectrodes. We will emphasize the need of customize the visual prosthetic device for the needs of each patient and the role of neural plasticity in order to achieve the desired results. Finally, we will discuss some of the exciting opportunities and challenges that lie in this intersection of neuroscience research, biomedical engineering, neuro-opthalmology and neurosurgery.

Bio. Dr. Fernandez received a M.D. degree from the University of Alicante (1986) and a Ph.D. in Neuroscience with honors in 1990. He is currently Professor and Chairman of the Department of Histology and Anatomy of the University Miguel Hernández (Spain), Director of the Neural Engineering Group of the Centro de Investigación Biomédica en Red (CIBER) in the subject area of Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN, Spain), and Adjunct Professor at John Moran Eye Center (University of Utah, USA). He is a qualified MD who combines biomedicine (molecular and cellular biology, biochemistry, anatomy, physiology and regenerative medicine) with the physical sciences and engineering to develop innovative solutions to the problems raised by interfacing the human nervous system. In the latest years he has been coordinating several National and International projects to demonstrate the feasibility of a visual neuroprosthesis, interfaced with the occipital cortex, as a means through which a limited but useful sense of vision could be restored to profoundly blind. Furthermore, he is also working on brain plasticity and brain reorganization in severe vision loss.

Non-invasive neural inferfacing with high-information transfer with the human spinal cord

Dario Farina, Professor and Chair in Neurorehabilitation Engineering, Imperial College London, UK.

Alpha motor neurons receive synaptic input that they convert into the ultimate neural code of movement -- the neural drive to muscles. The study of the behaviour of motor neurons provides a window into the neural processing of movement. Recently, the interfacing (bioelectrodes) and processing methods for identifying the output of motor neuron pools from interference electromyogram (EMG) signals have been advanced substantially. In the past decade, these methods have indeed allowed the monitoring of the behaviour of tens to hundreds of motor neurons concurrently, with minimally invasive or non-invasive methods. This new population analysis has opened new perspectives in the study of neural control of movement. The talk will overview the technology for motor neuron interfacing as well as the potential of motor neuron recording technology for man-machine interfacing. Examples of closed-loop neural interfacing based on non-invasive decoding of spinal motor neuron behaviour will be discussed in relation to assistive and rehabilitation devices.
