SUMMARY:Photonics Initiative Seminar: Arthur D. Yaghjian
DESCRIPTION:Dr. Arthur D. Yaghjian (Electromagnetics Research) \nRobust Field-Based Antenna Quality Factor\nAbstract – New field-based quality factors Q(ω) are derived for antennas with known fields produced by an input current. These Q(ω) are remarkably robust because they equal the input-impedance bandwidth quality factor QZ(ω) when the input impedance is available. Like QZ(ω)\, the field-based Q(ω) is independent of the choice of origin of the antenna fields and is impervious to extra lengths of transmission lines and surplus reactances. These robust field-based quality factors are used to derive new lower bounds on the quality factors (upper bounds on the bandwidths) of spherical-mode antennas that improve upon the previous Chu/(Collin-Rothschild) lower bounds for spherical modes. \nBio –  Dr. Arthur D. Yaghjian received the B.S.\, M.S.\, and Ph.D. degrees in electrical engineering from Brown University in 1964\, 1966\, and 1969\, and an Honorary Doctorate from the Technical University of Denmark in 2020. After teaching for a year\, he joined the research staff of the National Institute of Standards and Technology (NIST)\, Boulder\, CO in 1971 and transferred in 1983 to the Air Force Research Laboratories\, Bedford\, MA until 1996 when he became an independent researcher. His early research at NIST helped pioneer the development of probe-corrected near-field antenna measurements for accurately characterizing modern antennas in both the frequency and time domains. More recently\, he has extended the spherical-wave near-field antenna theory to the rigorous analysis of the partially coherent fields radiated by the sun and other stars. His research in electromagnetic theory has led to the fundamental determination of electromagnetic fields in spatially dispersive as well as temporally dispersive natural materials and metamaterials. He has derived the definitive microscopic and macroscopic force and energy expressions for both diamagnetic and paramagnetic media. He has contributed significantly to the determination and fundamental understanding of the classical equations of motion of accelerated charged particles. In the area of high-frequency diffraction\, he and Robert Shore obtained convenient robust expressions for incremental length diffraction coefficients that are currently used to predict bistatic scattering and reflector antenna performance in commercial high-frequency computer codes. His work with Steven Best on the fundamental characterization of antennas\, including the determination of the upper bounds on the bandwidth of complex antennas\, has had a major impact on the research and development of modern electrically small antennas. He holds the patent on supergain electrically small antennas. He is an IEEE Life Fellow and has been an IEEE-APS Distinguished Lecturer. He has received the IEEE Electromagnetics award\, the IEEE-APS Distinguished Achievement award\, four IEEE Schelkunoff prize paper awards\, and has written two well-referenced books\, one co-authored with Thorkild Hansen. \nThis is an in-person seminar.  If you opt to join via zoom use meeting ID 595 955 6744 Passcode 842444

SUMMARY:Interdisciplinary Seminar Series featuring Associate Professor Dr. Xi Chen
DESCRIPTION:EvapoFlex: Water-responsive Materials for Evaporation Energy Harvesting \nMany important physiological functions of living organisms (e.g.\, plant seed dispersal\, bacterial spore activation) rely on water-responsive (WR) materials that mechanically deform in response to changes in relative humidity. Recently\, biological WR materials have been shown to generate significantly higher energy actuation compared to all known animal muscles and mechanical actuators. These materials have enabled the development of evaporation energy harvesting generators that operate autonomously when placed at a suitable air-water vapor interface. Theoretical and physical studies suggest that these devices are highly scalable and could produce power densities comparable to current solar and wind farms\, while mitigating the intermittency issue that is often experienced by these renewable energy sources. \nTo transform the field of WR materials and their associated evaporation energy harvesting techniques\, we employ a convergent and deeply interdisciplinary approach. We term this overall effort EvapoFlex. We expect that EvapoFlex will establish a comprehensive framework to harness the ubiquitous and untapped energy embodied within natural and industrial evaporative water sources for actuation\, renewable energy conversion\, and environmental protection. We see our energy production system as highly unorthodox yet promising\, and admittedly a high-risk/high-reward enterprise. If successful\, EvapoFlex will lead to a previously unrecognized clean energy resource of water evaporation with power production potential comparable to that of current solar and wind farms\, but at a much lower economic and resource cost\, few intermittency issues\, and with a high potential for public acceptance.

SUMMARY:Seminar in Biochemistry\, Biophysics\, and Biodesign: Stephen D. Fried\, Assistant Professor Department of Chemistry
DESCRIPTION:Abstract: Recent advances in artificial intelligence have addressed a long-standing question in protein biophysics: What is the relationship between a protein’s primary sequence and its native three-dimensional structure? On the other hand\, the process by biosynthesis or following their denaturation is perilous\, complex\, and much less predictable. Many proteins misfold\, a process which can sometimes be reverted (but not always) through chaperones\, and is moreover associated with a wide range of ailments\, particularly neurodegenerative diseases. My lab became interested in delineating which (kinds of) proteins are capable of refolding into their native conformations spontaneously versus which ones require chaperone assistance. To do so\, we developed limited proteolysis mass spectrometry (LiP-MS) methods\, a structural proteomic approach that can interrogate protein conformation and misfolding on the proteome scale. These experiments provide a holistic view of what properties facilitate refoldability and have highlighted an important and unexpected role for intrinsically disordered regions. In this talk\, I want to emphasize that despite great strides in AI-based tools\, there are still many surprises for this field. For instance\, we have recently discovered a case of a protein whose misfolded form is even more kinetically stable than its native form. We also have documented a case of a protein whose folding is obstructed (rather than promoted) by the chaperone\, Trigger Factor. Though it remains to be seen how widespread these “unusual” cases are\, these results highlight the importance of us continuing to think deeply about protein folding with the spirit of curiosity and exploration\, and showcases the power of emerging proteome-wide experimental approaches. \n  \nPlease use this link to access Zoom. \nMeeting ID: 914 4825 7859\nPasscode: asrc+ccny

SUMMARY:Photonics Initiative Seminar: Weidong Zhou
DESCRIPTION:Dr. Weidong Zhou\, Photonics Center\, University of Texas at Arlington (UTA) \nScaling towards high-power single-mode PCSELs and PCSEL Arrays\n(Photonic Crystal Surface-Emitting Lasers)  \nAbstract \nWhen it was first invented 60 years ago\, the laser was described as “A solution looking for a problem”. Few predicted that lasers would ultimately support multi-trillion-dollar photonics-enabled markets today. Based on the Fano resonances in photonic crystal cavities and transfer printing heterogeneous integration platform\, we have been working on next-generation semiconductor photonic crystal lasers and related heterogeneously integrated nanophotonic and optoelectronic devices for chip-scale integrated system applications. In this talk\, I will first describe how hybrid and monolithic photonic crystal lasers can address the grand challenges of energy-efficient on-chip lasers\, followed by presentations on scaling challenges in photonic crystal surface-emitting lasers (PCSELs) with high-power\, high brightness\, and high speed. In the second part\, I will discuss heterogeneously integrated photonic crystal optoelectronic devices based on the micro transfer printing process\, including high-speed photonic crystal spatial light modulators and monolayer graphene total absorption in critically coupled photonic crystal cavities and designs toward high speed reconfigurable intelligent surfaces. \nWeidong Zhou is a Distinguished University Professor and Janet and Mike Greene Professor at the University of Texas at Arlington (UTA). He obtained BS and ME degrees from Tsinghua University\, China\, and a Ph.D. degree from University of Michigan\, Ann Arbor. After graduation\, he spent three years at CIENA Corporation working on optical transceiver modules and subsystems for optical communication systems. Prof. Zhou and his group have made significant contributions to semiconductor heterogeneously integrated photonic crystal membrane photonics\, especially photonic crystal lasers\, modulators\, and sensors\, for integrated silicon photonics and flexible optoelectronics. He has published over 400 journal papers and conference presentations\, including many papers published in high-impact journals such as Nature Photonics\, Nature Communications\, Nature Biomedical Engineering\, etc. He has also delivered over 100 invited conference talks. Dr. Zhou is a fellow of SPIE\, a fellow of Optica\, a senior member of IEEE\, and a member of APS and AAAS. He is the Director of UTA Photonics Center. \nThis is an in-person seminar.

SUMMARY:Photonics Initiative Seminar: Danial Motlagh
DESCRIPTION:Dr. Danial Motlagh\,  Xanadu \nTitle: A Renaissance in Materials Discovery \nAbstract – Quantum computers have the potential to transform materials discovery for next-generation technologies from a slow and expensive trial and error process into a fast\, cost-effective\, simulation-driven endeavour. In this talk\, I’ll share our vision for a quantum-accelerated materials discovery pipeline and the regimes we believe quantum computers can have the greatest impact in solving real-world problems. I’ll walk through our recent progress toward that goal by introducing our newly developed suite of quantum algorithms for studying functional properties of photoactive materials and our efforts in connecting them to real-world energy applications. \nBio – Danial Motlagh entered the field of quantum computing during his computer science studies at the University of Toronto. Ever since\, he’s been dabbling in all things quantum\, utilizing his expertise in algorithms to develop novel and more efficient quantum algorithms. \nDanial Motlagh started at Xanadu (www.xanadu.ai) two year ago as an intern and now he is the Lead Quantum Algorithm Scientist. \nThis is an in-person seminar.

SUMMARY:Seminar in Biochemistry\, Biophysics\, and Biodesign: Benjamin Schuster\, Assistant Professor Department of Chemistry and Biochemical Engineering
DESCRIPTION:Negative noodles\, and positive ones too: Biophysics and bioengineering of intrinsically disordered proteins \nIntrinsically disordered proteins (IDPs) do not fold into a fixed three-dimensional structure\, yet they play important roles in biology. For instance\, many IDPs phase separate into biomolecular condensates that function as membrane-less organelles in cells. If IDPs are somewhat like a cooked noodle\, then condensates are roughly akin to a ball of cooked spaghetti\, or perhaps pasta primavera. In this talk\, I will describe three recent studies from my lab and collaborators\, relating to the biophysics and bioengineering of these “noodles.” I will begin by discussing engineered IDPs (including highly charged sequences) that have provided new insights into the molecular grammar of protein phase separation. Second\, I will present biophysical insights into the role of protein condensation in the SARS-CoV-2 viral lifecycle\, focusing on how phosphorylation within a cationic disordered\nregion toggles the material state and function of nucleocapsid protein condensates. Third\, I will demonstrate how nanoparticle surface engineering allowed us to achieve controlled and orthogonal partitioning of large particles into IDP condensates. Together\, these vignettes help link IDP sequence\, phase behavior\, rheology\, and function\, with implications for condensate biology and therapeutic targeting of condensates in disease.
