SUMMARY:Injectable Cryogels for Biomedical Applications:  from Tissue Engineering to Immunotherapy
DESCRIPTION:Sidi A. Bencherif\nUniversity of Rouen Normandy\nNortheastern University \n\nAcross cell therapy\, regenerative medicine\, and immunoengineering\, there is a need for advanced three-dimensional (3D) scaffolds that support cells\, modulate their behavior\, and guide tissue regeneration. Injectable biomaterials have become especially attractive\, offering minimally invasive delivery without the risks of open surgery while enabling precise placement within delicate tissues. In this context\, we introduced a breakthrough platform: large\, preformed macroporous cryogels that can be delivered through a standard needle–syringe system while preserving their structure and function [1]. Our 2012 report of the first injectable cryogel capable of passing through a hypodermic needle while maintaining native-like microenvironmental cues sparked widespread interest and helped redefine the design space of soft biomaterials [2]. These sponge-like constructs\, produced through environmentally friendly cryogelation\, exhibit unique features—including elasticity\, interconnected macroporosity\, and shape-memory behavior enabling complete geometric recovery after injection. Over the past decade\, injectable cryogels have emerged as a versatile and customizable class of biomaterials aligned with modern research priorities. They hold great promise for tissue repair\, controlled drug delivery\, cell therapies\, cancer immunotherapy\, and innovative vaccine platforms\, including those developed during the COVID-19 era [3–5]. \nAcknowledgements\nFinancial support from the Chaire d’Excellence de Normandie is gratefully acknowledged.  \nReferences\n[1] L.J.

SUMMARY:Building a minimal nucleus to understand structure and  mechanics of assembly
DESCRIPTION:Alexander Von Appen\nMPI of Molecular Cell Biology and Genetics \n\nThe nucleus\, the largest organelle in human cells\, plays a crucial role in protecting\, organizing\, and regulating our genome. Despite its complexity\, it undergoes remarkable dynamics during cell division: as the cell enters mitosis\, nuclear organization dissolves\, leading to the detachment of the nuclear membrane from chromatin. The nucleoplasm and cytoplasm merge into a single entity\, while the spindle distributes chromosomes to form daughter cells. Following this “open” mitosis\, the entire organelle reassembles within minutes\, prompting the central question: what molecular mechanisms drive nuclear self-assembly? \nI will present our latest efforts to reconstitute nuclear self-assembly processes\, which we study structurally using cryo-electron tomography and mechanically using optical tweezers. Specifically\, I will show how ESCRT proteins assemble to close the nuclear membrane and how DNA is organized at the chromatin–nuclear membrane interface. \n \n  \n  \nAbout speaker\nPhD\, EMBL Heidelberg\, with Martin Beck\, studying the structure of the human nuclear pore complex PostDoc\, UCSF San Francisco\, with Adam Frost\, studying the role of phase separation in ESCRT-mediated nuclear membrane assembly Since 2021\, Research Group Leader at the Max Planck Institute of Molecular Cell Biology and Genetics\, Dresden\, Germany \n \n

SUMMARY:From Molecules to Populations: How Single-Cell Stochasticity Drives Population Heterogeneity in Bacteria
DESCRIPTION:Murat Tuğrul\nHumboldt-Universität zu Berlin \n\nA central challenge in evolutionary biology is predicting how microscopic processes within a cell determine the macroscopic success of a population. While classical population genetics often treats cellular fitness as a scalar parameter\, real biological populations are characterized by profound phenotypic heterogeneity\, even among genetically identical individuals. In this talk\, I will present a multiscale framework that links biophysical mechanisms directly to population-level outcomes and heterogeneity. First\, I will show single-cell microscopy techniques that allow us to collect high-resolution data on physiological states\, gene expression\, and fitness components in bacteria. Integrating mathematical modeling with single-cell experiments\, I will demonstrate how stochastic damage dynamics and asymmetric segregation reshape individual lifespans and emergent population growth. Second\, I will focus on the complex regulatory systems controlling polygenic traits\, specifically the flagellar network. I will show how the biophysical logic of genetic networks generates phenotypic bimodality\, providing a strategic ‘hedge’ that might facilitate evolutionary survival. Finally\, I will argue for a transition toward a mechanistic evolutionary theory where the physics of the cell dictates the logic of adaptation\, offering new insights into global challenges such as antibiotic resistance. \n \n  \nAbout Speaker\nDr. Murat Tuğrul is a biophysicist and theoretical evolutionary biologist studying how stochastic processes at the single-cell level give rise to population-level heterogeneity and evolution. He is currently a Research Fellow in the Molecular Microbiology Lab at Humboldt-Universität zu Berlin\, where he combines mathematical modeling with single-cell data analysis to investigate the regulatory principles of bacterial flagellar systems. Previously\, he led a Marie Skłodowska-Curie project at Freie Universität Berlin focused on bacterial aging and damage accumulation in single cells. He completed his PhD at IST Austria\, developing biophysical and population genetic models of transcriptional evolution. His research integrates theory and experiment to build predictive\, multiscale frameworks for understanding how cellular processes shape fitness and evolution in microbial populations. \n \n

SUMMARY:Highly Crystalline Organic Mixed Ionic-Electronic Conductors for Microfiber-Based Bioelectronic Interfaces and Energy Storage Devices
DESCRIPTION:Myung-Han Yoon\nGwangju Institute of Science and Technology \n\nIn this research\, we report highly crystalline organic mixed ionic-electronic conductors (OMIECs) designed to overcome the inherent trade-off between electrical/electrochemical performance and long-term aqueous stability. First\, by introducing a sulfuric acid treatment\, we successfully crystallized poly(3\,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) films. These films exhibit excellent electrical\, electrochemical\, and optical properties\, alongside robust long-term stability and high biocompatibility for primary cultured cardiomyocytes and neurons over several weeks. Consequently\, they were successfully employed in high-performance multi-electrode arrays (MEAs) to record and stimulate the electrophysiological activities of primary cardiomyocytes and chicken retinal tissues. Furthermore\, we developed the fabrication of crystalline PEDOT:PSS microfibers and a unique self-fusion process to create single-strand wearable electrochemical transistors and 3D microfibrillar network-based bioelectronic interfaces. Finally\, we demonstrated fiber-type energy storage devices by implementing carbon nanotube (CNT) yarn/PEDOT:PSS core-shell fibers. \n \n  \n1. Kim\, S.-M.\, et al.

SUMMARY:From sound fields to functions through the design of acoustic operators for microscale particle control
DESCRIPTION:Carlos A. Dorao\nNorwegian University of Science and Technology \n\nManipulating micro- and nanoscale particles is fundamentally challenging because\, at small scales\, conventional forces behave very differently. Particles are dominated by viscous drag\, Brownian motion\, and surface forces\, making them difficult to control precisely without physical contact or chemical labeling. Traditional mechanical or optical methods can be invasive\, complex\, or difficult to scale\, especially when dealing with delicate biological samples or large numbers of particles. This is where acoustic manipulation offers a compelling alternative. Sound waves can generate contactless\, gentle\, and tunable forces inside fluids\, enabling us to design acoustic operators that perform tasks such as patterning\, concentration\, mixing\, and lysis. By structuring the acoustic field in space and time\, we can create programmable operations that act on particles across a wide range of sizes. \n \n  \nAbout Speaker\nProfessor Carlos A. Dorao is a professor at the Department of Energy and Process Engineering at the Norwegian University of Science and Technology (NTNU). He holds an engineering degree in Nuclear Engineering from the Balseiro Institute (Argentina) and a PhD in Chemical Engineering from NTNU. His research focuses on the development of acoustic operators for the manipulation of micro- and nanoscale particles using sound waves as well as on fundamental thermohydraulics with an emphasis on identifying dominant heat transfer mechanisms in two-phase flow systems and understanding how flow oscillations influence these mechanisms. \n

SUMMARY:Quantum Dots: Fundamentals to Quantum Networks
DESCRIPTION:Yusuf Karlı\nUniversity of Cambridge \n\nQuantum networks promise fundamentally new ways to communicate and process information by harnessing the laws of quantum mechanics. Semiconductor quantum dots offer a practical and scalable platform for realizing many of the key components required for such networks. Because quantum dots confine charge carriers in all three spatial dimensions\, they exhibit discrete\, atom-like energy levels that enable precise control over light–matter interactions. \nThis talk introduces the basic physics of quantum dots and explains how their optical properties enable the on-demand generation of single photons and entangled photon pairs. It then explores how interactions between confined spin states and emitted photons create spin–photon entanglement\, providing a direct interface for quantum networking\, and highlights how these capabilities position quantum dots as promising building blocks for quantum networks\, with applications ranging from secure communication to distributed quantum information processing. \n \n  \nAbout Speaker\nYusuf Karli completed his PhD at the University of Innsbruck in 2024 with Gregor Weihs\, working on single and entangled photon generation from quantum dots. His PhD work was awarded IQOQI Thesis Prize by the Austrian Academy of Sciences. He then joined Mete Atatüre’s group at the University of Cambridge\, where he works on quantum memory and quantum network applications using quantum dots. Since October 2025\, he has been elected as Fellow and Director of Studies Natural Sciences at Emmanuel College\, University of Cambridge. \n \n

SUMMARY:Electrospun Nanofibers and Advanced Materials for Energy Storage and Conversion
DESCRIPTION:Begüm Yarar Kaplan\nSabancı University Nanotechnology Research and\nApplication Center (SUNUM)\, Turkey\nPadova University\, Italy \n\nElectrospinning is a highly versatile and powerful technique for producing nanostructured materials\, particularly suited to energy storage and conversion applications [1]. It enables the fabrication of nanofibrous electrodes and membranes with exceptionally high surface area\, uniformly distributed ionically conductive phases\, and finely tunable porosity. These features collectively enhance mass transport\, ionic conductivity\, mechanical/thermal/chemical stability\, and catalytically active sites in devices such as fuel cells\, electrolyzers and batteries. Beyond their performance advantages\, electrospun architectures are simple\, scalable\, and cost-effective to manufacture\, making them ideal candidates for next-generation energy materials. \nIn this presentation\, next-generation polymer electrolyte membranes will first be introduced\, including composite/hybrid\, layered\, and bipolar membrane designs engineered for high-performance fuel cells and electrolyzers. These advanced membranes\, fabricated through electrospinning\, exhibit controlled swelling\, enhanced ionic conductivity\, improved mechanical robustness\, and superior overall device performance [2]. The second part of the talk will focus on novel strategies for developing highly active\, durable\, and economically viable electrocatalysts and electrodes. This section will cover both platinum-group-metal (PGM) and PGM-free electrocatalysts incorporated into electrospun nanofiber-based electrodes tailored specifically for fuel cells and electrolyzers [3\,4]. In the final part of the talk\, recent research in electrospun nanofiber-based electrodes and interlayers for Li-ion batteries will be discussed\, in which their porous\, high-surface-area networks enhance electrolyte interactions\, increase void volume to facilitate more efficient Li+ transport\, and improve charge-transfer kinetics [5]. \n \n[1] Cho\, Y.\, Baek\, J.

SUMMARY:Engineering light to hop or walk through photonic nanostructures: Fundamental puzzles to sustainable industrial applications
DESCRIPTION:Willem L. Vos\nUniversity of Twente \n\nThe study of the propagation of light through complex composite materials – e.g.\, paint\, foam\, bio-logical tissue – is a topic that has become a field of its own [Nov2012\, Car2021]. This may seem surprising: if a material is so opaque that it scrambles images\, how can one see through? If a laser beam is scram¬bled\, how does optical interference survive? The answer is in essence that interferences survive even millions of scattering events\, observable as speckle or enhanced back scattering. Know-how of light scattering serves to address challenges in high-tech industry – from lighting\, CMOS metrology\, to atmospheric sensing – for sustainable technology\, see Fig. 1 [FFSO].\n \nFigure 1. Schematic illustrating how the joint engineering of broadband light waves by nanostructure and wavefront shaping optimizes light on a target\, for sustainable high-tech appli¬cations. \nThree complementary tools are crucial to control light interference in complex materials: nanostructure\, shape (freeform)\, wavefront shaping. (1) Much progress is made to realize nanostructures: periodic [Goo2023]\, cav¬ity superlattices [Adh2024]\, or chiral [Ota2019]. The chal-lenge to get calibrated densities is met by using in situ X-ray imaging. Since X-ray methods are non-destructive\, devices are available for further study or integration [Sch2024]. (2) External sample shape\, long neglected\, is remarkably crucial\, as known in industry\, and now also in wavefront shaping [Rat2023a]. (3) Wavefronts shaped with SLMs offer many control parameters to meet a desi¬red goal like a highly optimized focus (Fig. 1). This is used to send light deep into a forbidden gap [Upp2021]\, or do secure optical communication [Rat2023b]. A new topic is mutual scattering where extinction (shadow) is control¬led to make objects more transparent or darker\, or sense particle displacement in opaque materials [Rat2024\, Tru2022]. \nFinally\, even the transport of light intensity without interference – at the basis of most scattering optics – still holds puzzles\, notably when well-known models like diffusion break down [Akd2024]. \n  \n[Akd2024] O.

He held a prestigious Fellowship from the Carnegie Institution for Science (USA) where he discovered a novel class of “van der Waals compounds” at very high pressures in the Geophysical Laboratory (Nature 1992).\nHe then became one of the first to study photonic crystals at optical frequencies\, niftily combining colloid physics and synchrotron X-ray methods. His team developed powerful “inverse opal” photonic crystals\, reported in an influential Science paper (~2400 Google citations). Since 2002 Vos is professor of Complex Photonic Systems (COPS) at the University of Twente. His team demonstrated the first ever control of spontaneous emission of light with photonic crystals (Nature 2004)\, and with a complete 3D photonic band gap (PRL 2011).\nHis COPS team pioneered optical wavefront shaping\, a revolution in optics to “unscatter” scattered light\, leading to novel applications in imaging\, microscopy\, and optical communication using opaque materials. Vos leads major multi-million-euro-consortia that closely collaborate with major high-tech industries and SMEs (with 30 BEUR annual turnover)\, to solve practical high-tech problems with advanced nanophotonics.\nVos was elected Fellow of the APS and of Optica (formerly: OSA)\, and awarded the Snellius medal and the Descartes-Huygens prize by the French Académie des Sciences. He has been guest professor at leading institutions (LPMMC\, CNRS\, Grenoble\, and Langevin Institute\, ESPCI\, PSL\, Paris). His papers are on average cited >40x. Willem Vos takes much pride in his students who have become faculty members at leading institutes\, or pursue careers in major industries as well as in non-profit organizations. \n  \n \n

SUMMARY:Engineering Tissues Layer by Layer: 3D Bioprinting with Bioinspired Nanomaterials
DESCRIPTION:Ahmad Rashad Elsebahy\n1- Center of Translational Oral Research\, Department of Clinical Dentistry\,\nUniversity of Bergen\, Norway.\n2- Bioengineering Graduate Program\, University of Notre Dame\,\nNotre Dame\, Indiana\, United States.\n3- Terasaki Institute for Biomedical Innovation\, Los Angeles\,\nCalifornia\, United States. \n\nDespite significant advances in science and technology\, we are still unable to fully overcome simple medical conditions like tooth cavities and bone fractures\, not to mention more serious diseases. To achieve true healing\, there is a growing need to shift the current medical paradigm toward regenerative strategies that can restore both the structure and function of native tissues. However\, living tissues are inherently sophisticated structures\, composed of multiple cell types embedded within multiscale\, multi-material composites precisely organized in layers to perform specific biological and mechanical functions. These natural matrices range from the nanoscale\, where molecules self-assemble into functional architectures\, all the way to centimeter-scale tissues\, as seen in human bones or plant structures like trees. Bones and trees have remarkable structural and molecular similarities. At the nanoscale\, the helical arrangement of collagen fibrils in bone closely resembles the arrangement of cellulose fibers in wood. Both structures are optimized to withstand mechanical stress. This structural-functional complexity presents both a challenge and blueprint for developing advanced tissue engineering strategies. Achieving such structural and functional fidelity requires advanced fabrication technologies\, such as 3D bioprinting\, which enables the accurate positioning of bioinks composed of diverse cells\, biomaterials\, and biologics in layer-by-layer architectures that closely recapitulate the native tissue environment. \nThis lecture will highlight some of my previous work on the integration of extrusion-based bioprinting with bioinspired nanomaterials\, specifically cellulose nanofibers and nanohydroxyapatite\, to fabricate scaffolds that replicate the architecture of both compact and spongy bone tissues. Following comprehensive in vitro and in vivo biocompatibility studies\, nanocellulose with varied surface chemistries was employed to fine-tune nanostructured\, multi-material inks derived from a diverse library of biopolymers\, including gelatin\, gelatin methacryloyl\, alginate\, fibrin\, polyesters\, and polycarbonates. In formulations where human mesenchymal stromal/stem cells were incorporated into hydrogel precursors and printed to mimic bone extracellular matrix\, nanocellulose imparted exceptional shear-thinning properties\, effectively overcoming the rheological limitations associated with nanoceramic printing. To address the mechanical weakness of printed hydrogels and better emulate the load-bearing nature of compact bone\, a modified 3D printing strategy using thermoplastic polymers with bone-inspired designs was employed. These thermoplastic scaffolds were further coated with nanocellulose or magnesium-doped nanohydroxyapatite to enhance cellular integration and biological performance. \nFinally\, the lecture will discuss opportunities to integrate 3D printing technologies for tissue engineering and personalized medicine into UNAM’s research and entrepreneurial initiatives\, with the aim of advancing these innovations toward clinical application and achieving meaningful real-world impact. \n  \nAbout speaker\nDr. Ahmad Rashad Elsebahy is a dentist and tissue engineering researcher dedicated to bridging clinical needs with cutting-edge regenerative medicine. He is currently a Senior Researcher at the University of Bergen’s Tissue Engineering Group in Norway\, and also holds research affiliations with the Terasaki Institute for Biomedical Innovation (USA) and the University of Notre Dame’s Bioengineering Program (USA). Dr. Ahmad Rashad is a graduate of Alexandria University’s School of Dentistry in Egypt. He practiced dentistry for six years\, including a year-long residency in oral surgery\, before transitioning to tissue engineering research. His career has spanned three continents\, beginning with a Master’s in Biomaterials Science between Alexandria and Lehigh (USA) Universities\, where he engineered nanoporous bioactive glass scaffolds. In Japan at Nagasaki Dental School\, he developed regenerative dental nanomaterials\, followed by a PhD at the University of Bergen (Norway) focusing on 3D bioprinting stem cells in nanocellulose hydrogels. During his postdoc in Norway\, he established the group’s biofabrication platform\, secured over €4 million in grants\, co-founded Bergen’s first clinical startup for 3D-printed bone implants\, and patented several novel bone tissue engineering scaffolds. At the Terasaki Institute and Notre Dame\, his research expanded into personalized medicine\, shear-thinning nanomaterials\, biosensors\, microfluidics\, bioethics\, and stem cell–based bioprinted scaffolds for diabetic wound healing using cell-derived exosomes. With 40+ publications\, mentorship of 6 PhD and 3 Master’s students\, and co-founding a MedTech startup\, Dr. Ahmad Rashad exemplifies the fusion of clinical insight\, bioengineering innovation\, and translational vision to advance the future of regenerative therapies \n \n  \n

SUMMARY:Smart Self-assembly for Sustainable Nanophotonics and Optoelectronics
DESCRIPTION:Talha Erdem\nAbdullah Gül University \n\nReducing the greenhouse gas emissions have already been accepted as the straightforward way to limit the environmental effects of the global warming. Toward this aim\, significant efforts have been put forward in the field of photonics as well. For example\, solar energy became a significant source of energy and light-emitting diodes promising a lower energy consumption became the main devices used lighting applications. However\, the widespread use of these technologies has a cost: the dependence on rare earth elements. As part of the efforts to eliminate this dependence\, our group works on the utilization of colloidal nanoparticles to produce nanophotonic structures and optoelectronic devices using controllable self-assembly methods\, i.e.\, smart self-assembly. \nIn this talk\, we will first discuss our work where we tailored the electrostatic self-assembly of colloidal quantum dots on 2D surfaces using light [1]. Owing to the local heating due to laser irradiation\, the quantum dots gain enough kinetic energy such that they can escape the electrostatic attraction. This approach allowed us to produce patterns having 100s of micrometers by a few centimeters. Next\, we will present the opportunities that the light-assisted local heating offers for DNA-driven self-assembly. Within this framework\, we will first explain our results on tailoring the optical transmission of the self-assembled networks made of DNA-functionalized gold nanoparticles [2]. Subsequently\, we will continue with the control of 2D self-assembly of DNA-functionalized quantum dots as part of our efforts towards developing novel fabrication technologies [3]. We will then talk about our novel photodetector application made of the DNA-functionalized metal and semiconductor nanoparticles. Owing to DNA-DNA interaction\, these photodetectors exhibit a negative responsivity [4]. Next\, we will present our work in which we explored how to customise the optical polarization of magnetic and self-assembled quantum dot supraparticles [5]. We report on our efforts to produce CdSe/ZnS quantum dots\, iron oxide nanoparticles\, and silver nanoparticle supraparticles. We then demonstrate the magnetic field-dependent optical polarization control of the quantum dot-iron oxide supraparticle network. Finally\, we will present the formation of translucent photonic crystals of latex nanoparticles [6]. These particles form 3D photonic crystals when they are concentrated. Their reflection colors can be easily tailored by changing the final concentration of the material as controlling the concentration enables controlling the distance between the particles forming the photonic crystal. \nReferences\n[1] Akrema et al.\, J.

SUMMARY:Optimizing the information content of coherent light
DESCRIPTION:Allard P. Mosk\nUtrecht University \n\nRandom scattering of light\, which takes place in paper\, paint and biological tissue is an obstacle to imaging and focusing of light and thus hampers many applications. At the same time scattering is a phenomenon of basic physical interest and its relation to the information content of light is subtle [1] and in many cases focusing and imaging are still possible [2]. Here we show shaped light fields that are relevant to imaging and measurements in scattering environments. Firstly\, we present maximum information states\, which are light states that carry a maximum amount of information about a given observable\, enabling the most precise measurements that are possible given a coherent input beam [3]. Conversely\, scattering invariant modes are the least sensitive modes to the presence of a scattering sample and they retain the same output profile whether propagated through a scattering material or through air\, as visualized in Fig. 1. We demonstrate these states experimentally and show numerically their relevance to imaging and metrology inside scattering media [4]. \n \nReferences:\n1. A. P. Mosk\, A. Lagendijk\, G.

Major results in this field were the first observation of photoassociation of hydrogen and of the Feshbach resonance in lithium\, and the original proposal for observation of negative-temperature states in atomic gases. In 2003 he entered the field of optics in complex media\, where he developed methods to control diffusive light. In 2007 his team demonstrated the first focusing of light through strongly scattering media. The wavefornt shaping method at the basis of this work has been used in many new imaging and focusing modalities worldwide. In 2012 the team demonstrated fluorescence imaging through scattering media using speckle correlations\, a method quickly picked up by other groups worldwide. His present research interests include imaging and industrial metrology using scattered light\, and innovations to reduce the impact of the climate crisis. \n  \n  \n \n  \n  \n\n  \n

SUMMARY:Stochastic Resetting of Diffusive Particles: From Single-Particle Dynamics to Many-Body Phenomena
DESCRIPTION:Gregory Schehr\nSorbonne University \n\nStochastic processes under resetting have garnered increasing attention in recent years. One of the simplest examples involves a diffusive particle whose position is randomly reset to a fixed point\, such as its initial position\, at a constant rate r. Even this basic system reveals fascinating phenomena: (i) the system reaches a nontrivial nonequilibrium stationary state\, and (ii) the mean time for the particle to reach a target becomes finite\, with an optimal resetting rate r that minimizes the search time. \nAfter introducing these intriguing features\, I will extend the discussion to a one-dimensional gas of N independent Brownian particles\, all of which are reset simultaneously to the origin at a constant rate r. Despite the absence of direct interactions between the particles\, I will demonstrate that strong correlations emerge in the stationary state at long times\, purely driven by the dynamics of resetting itself. \n  \nAbout speaker\nI earned my PhD in Theoretical Physics from École Normale Supérieure in 2003\, followed by a postdoc at the University of Saarland\, Germany. In 2006\, I joined CNRS and became a Research Director at Sorbonne Université in 2019. Since 2023\, I have also been a Professeur Chargé de Cours at École Polytechnique. My research focuses on statistical mechanics\, including non-equilibrium dynamics\, random matrices\, disordered systems or extreme value statistics. I received the CNRS Bronze Medal in 2010 and the Aniuta Winter-Klein Prize from the Academy of Sciences in 2022. \n  \n \n  \n\n  \n

SUMMARY:Acoustofluidics for ultrafast mixing and personalised drug delivery
DESCRIPTION:Tuncay Alan\nMonash University \n\nAcoustofluidics for ultrafast mixing and personalised drug delivery \nAt the Dynamic Micro Devices Laboratory\, we study the interaction between nonlinear micro/nanoscale resonators and fluid media\, developing acoustically actuated microsystems. This seminar will present recent advances in these technologies\, with applications in chemical synthesis\, drug delivery\, and liquid atomization\, and their potential impact in healthcare. \nThe first part of my talk will focus on ultrafast\, high-throughput microfluidic mixers capable of high precision synthesis of nanomaterials. These mixers can homogenize solutions in under milliseconds\, at flow rates approaching 10 ml/min. Such rapid mixing enables precise control over the size and composition of the end products\, (ranging from organic nanodrugs to perovskites used in optoelectronics) achieved solely through mechanical processes without altering reaction conditions. \nThe second part will introduce a liquid atomization technology\, PALM\, and discuss how it can be used for targeted respiratory drug delivery. With its unique design and responsive operation\, PALM can precisely dial the size and dose of the aerosolised drug based on the disease\, lung capacity and breathing cycle of the patient\, using a portable easy to use device offering effective personalised treatment which is not possible with any other device. Unlike its competitors\, PALM can also control the strength and duration of the pressure waves during aerosolization and preserving the therapeutic agents. \n \n  \n\nKonuşmacı hakkında\nTuncay Alan is an Associate Professor in the Department of Mechanical and Aerospace Engineering at Monash University in Melbourne\, Australia. He received his BSc in Civil Engineering from Middle East Technical University\, and his PhD from Cornell University in Ithaca\, New York. Before joining Monash\, he completed postdoctoral research at Delft University of Technology in the Netherlands and University College London in the UK. He has also held positions as a Visiting Scientist at the Paul Scherrer Institute in 2015 and as a Guest Professor at ETH Zurich in 2023. \n  \n \n  \n\n  \n

SUMMARY:Nonlinear dynamics and chaos in multimode semiconductor lasers
DESCRIPTION:Stefan Bittner\nUniversity of Lorraine \n\nNonlinear dynamics and chaos in multimode semiconductor lasers \nNonlinear dynamics and deterministic chaos are ubiquitous in nature and appear in a large variety of physical\, chemical and biological systems. Due to their strong nonlinearities\, lasers exhibit a very wide range of different dynamics and are ideal testbeds for studying chaotic dynamics. Interest in laser dynamics has been renewed due to emerging applications of ultrafast chaotic dynamics like chaos cryptography\, physical random number generation\, sensing applications like chaotic LIDAR or information processing and reservoir computing [1]. Semiconductor lasers are ideal for realizing chaos-based applications thanks to their ultrafast dynamics\, compact size and low energy consumption. \nIn the first part of the talk\, we present the experimental investigation of a free-running broad-area VCSEL (vertical cavity surface emitting laser) [2]. We observe mode competition between lasing modes with different spatial patterns and polarizations. Time-domain measurements of the laser emission show irregular fluctuations\, and we use methods from time-series analysis to confirm that the VCSEL exhibits chaotic dynamics in certain parameter regimes. Such lasers with intrinsic chaotic dynamics are promising candidates for applications like chaos cryptography. \nIn the second part of the talk\, the detailed investigation of an edge-emitting broad-area laser is presented [3]. Time-domain heterodyning measurements enable us to obtain the spectrum of the laser with ultra-high resolution. In addition to the expected transverse modes of order 1 to 8\, we find that multiplets of 1st and 2nd order transverse modes are created by the nonlinear dynamics. We demonstrate that the modes in these multiplets are phase-locked\, which is unexpected for a broad-area laser without external perturbation or control. The coexistence of synchronized (phase-locked) modes and unsynchronized ones is similar to so-called chimera states found in networks of coupled oscillators [4] which also exhibit partial synchronization and are found in various physical\, chemical and biological systems. \n\nHigh resolution spatio-spectral image of a broad-area semiconductor laser pumped high above threshold. The frequencies and the spatial profiles of transverse modes of order 1 to 8 are revealed. \n[1] Sciamanna & Shore\, “Physics and applications of laser diode chaos”\, Nature Photonics 9\, 151 (2015)\n[2] Bittner & Sciamanna\, “Complex nonlinear dynamics of polarization and transverse modes in a broad-area VCSEL”\, APL Phot. 7\, 126108 (2022)\n[3] Bittner & Sciamanna\, “Spontaneous phase locking in a broad-area semiconductor laser”\, arXiv:2405.07268 (2024)\n[4] Abrams & Strogatz\, “Chimera States for Coupled Oscillators”\, Phys.

SUMMARY:Design meets evolution: Theory and practice
DESCRIPTION:Víctor de Lorenzo\nThe Spanish National Research Council (CSIC) \n\nDesign meets evolution: Theory and practice\n \nThe prevailing view of biological evolution is not unlike bricolage/pastiche/tinkering—in sharp contrast with rational engineering. Yet\, different paths often lead to solutions that coincide or converge whether they emerge from naturally-occurring evolution or rationally designed. Such a conjunction—often presented as a mere anecdote— in fact reveals the ability of biological systems to physically explore solution spaces and gravitate towards information-rich attractors\, which can be found through different routes. This scenario evokes one of heterotic computing\, a non-conventional type of data processing in which the solution to a problem is not delivered through numerical calculations but through its embodiment in a material object. Once left to undergo a physical process the object manages a large number of parameters for reaching a multi objective optimum. The course of information is thus a physical flow and the outcome is a physical currency. The consequences of this notion for bioengineering are remarkable\, as it enables solutions to multi-objective optimization challenges not yet amenable to all-rational approaches. The ensuing technical question is how to bring about hyper-diversification not only of genomic sequences but also environmental parameters for securing the desired performance of a given synthetic device. This issue will be illustrated with a number of practical cases where naturally-occurring or artificially enhanced variability was key to find ideal outcomes to otherwise intractable design hitches of interest for industrial and environmental biotechnology. \nAl-ramahi et al.

After his PhD at the CSIC Institute of Enzymology (1983)\, he worked at the Pasteur Institute (1984)\, the University of California at Berkeley (1985-1987)\, the University of Geneva (1988) and the Federal Center for Biotechnology in Braunschweig until 1991\, the year in which he joined the CSIC in Madrid. He specializes in Molecular Biology and Biotechnology of soil microorganisms (particularly Pseudomonas putida) as agents for the decontamination of sites damaged by industrial waste. At present\, his work explores the interface between Synthetic Biology and Environmental Biotechnology\, including global-scale bioremediation interventions for counteracting climate change. In 2001 this work received the National Award Rey Jaime I for Environmental Protection. In June 2008 he was honored with the GSK International Award of the American Society for Microbiology\, and in October of the same year he was granted a Grand Prix of the French Academy of Sciences. He is a member of the EMBO (European Molecular Biology Organization) and the American and European Academies of Microbiology\, and he has co-chaired with Anne Glover the President’s Science and Technology Council of the EC during the Barroso Administration.

SUMMARY:Polymeric Membranes - in gas- and liquid-phase separation
DESCRIPTION:Volkan Filiz\nHelmholtz-Zentrum Hereon \n\n  \nPolymeric Membranes – in gas- and liquid-phase separations \nThe main research focus at the Institute of Membrane Research at the Helmholtz-Zentrum Hereon is the development of membranes for liquid and gas phase separation. Water shortages\, climate change and energy transition: separation of substances plays a vital role in these challenges. We help provide solutions to these global problems at the Institute of Membrane Research by developing innovative membranes and membrane processes. This involves a holistic\, interdisciplinary approach: it includes developing new materials\, processing these materials into membranes as well as constructing pilot plants in which these systems are made ready for implementation.. \nSpecifically\, the synthesis and characterization of tailor-made polymers for membrane applications is in the foreground\, while the use of state of the art methods for fabrication of membranes with outstanding separation performances (e.g.\, in separation of CO2 in gas streams\, or protein separation in liquid phase) is the challenge that our Institute deals with. The focus of the talk will be polymers of intrinsic microporosity. \n  \nAbout Speaker\nVolkan Filiz is currently the head of the Department “Microporous Polymers” at the Helmholtz-Zentrum Hereon in the Institute of Membrane Research under the supervision of Prof. Volker Abetz. He has earned his B.S. and M.S. degrees in chemistry at the University of Hamburg\, Germany and received in 2009 from the Institute of Physical Chemistry his Ph.D. in chemistry under the supervision of Prof. Stephan Förster. The research topic was polymersomes for drug delivery and targeting. His research interests now include the synthesis of new monomers and tailor-made polymers for membrane applications in gas- and liquid-phase separation. \nHe is currently also involved in teaching at the University of Hamburg and is registered for habilitation at the University of Kiel. \n  \n \n  \n\n  \n

SUMMARY:Thermal Drawing Of Low-Dimensional Material-Integrated Triboelectric Fibers For Healthcare Applications
DESCRIPTION:Thermal Drawing Of Low-Dimensional Material-Integrated Triboelectric Fibers For Healthcare Applications \nMSc Thesis Defense \nMd Sazid Bin Sadeque\nAdvisor – Mustafa Ordu \nAbstract: The potential of flexible wearable devices and sensors to revolutionize healthcare lies in their ability to facilitate real-time monitoring. However\, many of these wearable sensors are extensive energy consumers\, and the requirement of bulky energy storage devices significantly hampers their acceptability. Currently available sensing devices mostly employ film-based devices\, which lack breathability\, reducing their applicability in widespread healthcare applications. Triboelectric nanogenerators (TENGs) are environmentally sustainable devices that convert mechanical and biomechanical energy into electrical output through the synergetic processes of triboelectrification and electrostatic induction. These devices effectively harvest low-frequency mechanical and biomechanical energy and enable self-powered sensing. TENG performance can be enhanced by incorporating low dimensional materials with high specific surface area into flexible ferroelectric polymers. Ferroelectric polyvinylidene fluoride (PVDF) and its copolymers are particularly advantageous due to their high dielectric constant and abundant highly electronegative fluorine ions. Various low dimensional materials can interact with the polar groups of PVDF and reorient them to conform to electroactive phases. Moreover\, they can also form micro-capacitors and modulate the surface properties of nanocomposite. In this thesis\, we aim to prepare a triboelectric nanogenerator integrated textile fiber with self-energy generating ability and breathability as textiles. We employed the thermal drawing process as a fabrication platform for preparing continuous triboelectric fibers. Graphene nanoplatelet (GNP) and Molybdenum disulfide (MoS2) are added to the PVDF matrix to improve triboelectric properties. β phases of thermally drawn nanocomposite fibers demonstrate significant improvement and were increases to 37.6%\, 39.5%\, and 43.3% for 1\, 3\, 5% GNP integration. For the case of MoS2\, β phase increases to 47.5% for 3 wt% MoS2; however\, β phase decreases beyond 3 wt%. The nanocomposite TENG fibers demonstrate improved triboelectric properties. The fibers show superior sensitivity\, flexibility and durability\, enabling their applications in critical healthcare applications. \nKeywords: Triboelectric nanogenerator\, thermal drawing\, wearable sensors\, respiration monitoring\, blinking monitoring.
