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: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.

Vos\, Phys. Rev.

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:Repurposing Biomaterials and Its Applications
DESCRIPTION:Hojae Bae\nKonkuk University\, Seoul\, Korea \n\nRepurposing Biomaterials and Its Applications \nIn recent years\, numerous studies have been conducted on cultured meat; however\, the production of large-sized cultured meat continues to present a challenge. In this regard\, 3D bioprinting emerges as a promising approach for generating large cell aggregates to facilitate cultured meat production. Utilizing digital light processing-based (DLP) printing\, a hydrogel scaffold is created at the centimeter scale\, offering high printing accuracy and the ability to construct complex geometric structures. Successful fabrication of scaffolds incorporating living cells and large microchannels has been achieved. Notably\, the cooked cultured meat retains its original size and shape even after being cut\, with overall dimensions measuring 3.43 cm x 5.53 cm x 0.96 cm. This study demonstrates the proof-of-concept for utilizing bioinks in the production of 3D cultured meat. Nevertheless\, due to substantial disparities between the objectives of muscle tissue engineering for biomedical purposes and food applications\, conventional strategies may prove unfeasible or socially unacceptable. Consequently\, the pursuit of non-animal materials to foster muscle cell proliferation and alignment\, without resorting to potentially toxic chemical modifications\, represents an ongoing challenge. To address this\, recent studies focusing on culturing and aligning muscle cells solely through plant-based materials will be presented as a potential solution for cultured meat production. \n  \n \nFigure 1.

SUMMARY:The Sound of Music at the Nanoscale – Exploring the Nanoscale World with NEMS Resonators Based on Low Dimensional Nanomaterials
DESCRIPTION:Zenghui Wang\nUniversity of Electronic Science and Technology of China \n\nThe Sound of Music at the Nanoscale – Exploring the Nanoscale World with NEMS Resonators Based on Low Dimensional Nanomaterials \nThe advent of low-dimensional nanostructures has enabled a plethora of new devices and systems. Among them\, nanoelectromechanical systems (NEMS) offers the unique capability of coupling the exquisite material properties found in these atomically-defined nanostructures with their mechanical degree of freedom\, opening new opportunities for exploring exotic phenomena at the nanoscale.

SUMMARY:Effect of surface charged groups on colloidal\, optical properties and cellular uptake of inorganic nanoparticles
DESCRIPTION:Mikhail Artemyev\nBelarusian State University \n\nEffect of surface charged groups on colloidal\, optical properties and cellular uptake of inorganic nanoparticles \nSurface charged groups play enormous role in colloidal stabilization of inorganic nanoparticles in aqueous solutions. They also govern such important characteristics\, as electrophoretic mobility\, ability to electrostatic interaction with different objects from solid surfaces to biomolecules. Here\, I present our recent results on how to introduce different types of charged groups in the surface shell of semiconductor and metal nanoparticles\, how the sign and the magnitude of the surface charge and the type of groups affect colloidal stability of nanoparticles in aqueous media. Surprisingly\, the surface charge affects not only their electrophoretic mobility\, but indirectly their hydrodynamic size measured by DLS. Both strong negative and positive surface charge is capable to quench the photoluminescence of semiconductor quantum dots and cause a spectral shift of plasmon resonances in silver nanoparticles. Moreover\, various types of cells demonstrate selective uptake of colloidal quantum dots with specific surface charge. All of that demonstrates practical perspectives for utilization of charged plasmonic and semiconductor nanoparticles as the optical nano-sensors and markers. \n  \n  \nAbout Speaker\nGraduated chemistry department of BSU in 1985.

SUMMARY:Probing leaky and guided exciton-polaritons in resonant planar structures
DESCRIPTION:Anton Samusev\nITMO University \n\nPlanar periodic structures such as metasurfaces and photonic crystal slabs strongly coupled to an exciton resonance attract particular attention since they provide vast opportunities for on-demand engineering of the dispersion of guided and leaky polariton resonances. In this regard\, experimental characterization and control of the over modes’ dispersion is of great importance. In this talk\, I will show both what new physical phenomena appear in such systems and how these effects can be directly observed in the experiment. \nIn the first part of the talk\, I will show an experimental approach allowing to retrieve the real [1\, 2] or even full complex [3] dispersion of both leaky and evanescent waves in arbitrary planar structures. The method is based on back focal plane microspectroscopy combined with a solid immersion lens (SIL) separated from the sample by a precisely controlled nanoscale air gap (Otto geometry). Varying the gap allows for extracting both real and imaginary parts of the wavenumber of surface waves propagating in an arbitrary in-plane direction. \nIn the second part of the talk\, I will switch gears to another implication of dispersion engineering in planar structures – the possibility of realization of strong light-matter coupling regime with excitons in transition metal dichalcogenides [4\, 5] and perovskites [6]. I will highlight the nonlinear [4\, 6] and topological [5] properties of exciton polaritons in such systems enabled by finely tuned custom designs of the photonic band structure. \nFinally\, we will discuss how to directly observe and analyze guided exciton-polaritons in planar waveguides either made of a perovskite or based on high-index dielectric slab integrated with transition metal dichalcogenide monolayer. I will show how direct variation of radiative losses via changing the SIL-sample distance in such systems allows for the control of Rabi splitting\, and extraction of exciton-photon coupling strength along with the intrinsic properties of excitons in the sample under study. \nReferences\n1.
