SUMMARY:Shining Light on Solar Cells and Their Material Impacts
DESCRIPTION:Rachel Woods-Robinson\, PhD\, University of Washington Clean Energy Institute\nSponsored by California ACS\n10:30am-Noon\, Online via Zoom\, Free\, Registration required\n\nAbstract: Addressing climate change requires transitioning to renewables such as photovoltaic solar panels\, but one key barrier to this transition is that we need better materials. In this talk\, we’ll start at the sun and then zoom into a solar panel all the way down to the nanoscale\, highlighting materials challenges that scientists face at each length scale to make solar more efficient\, reliable\, and sustainable. We’ll meet the different material components\, such as absorbers and transparent conductors (TCs)\, and I’ll share some of my research into designing new TCs for solar. Next\, we’ll zoom back out to discuss challenges we face beyond the lab in bringing solar to society\, including critical raw materials\, environmental impacts\, and “green sacrifice zones.” Lastly\, I’ll share some insights from my outreach project Cycle for Science and college course Cycle the Rockies. \nAbout the speaker: Rachel Woods-Robinson (she/her) received a B.S. in Physics from UCLA\, and a Ph.D. at U.C. Berkeley and Berkeley Lab designing new crystals for solar energy by combining computational chemistry\, thin film growth\, and device fabrication. Rachel recently started as a Postdoctoral Fellow at University of Washington’s Clean Energy Institute to study environmental and human impacts of such new solar materials. In addition to research goals to curtail climate change\, Rachel aims to support scientists in sharing our work accessibly and engaging collaboratively with our communities\, and loves outdoor adventuring. She co-founded “Cycle for Science\,” in which scientists go on bicycle tours and visit K-12 classes to teach hands-on lessons about sustainability\, and she instructs “Cycle the Rockies” (Wild Rockies Field Institute)\, an immersive month-long course in which undergrads ride bicycles across Montana to learn about local energy and climate impacts.

SUMMARY:Programmable Shape Morphing & Responsiveness of Composite Hydrogels
DESCRIPTION:Prof. Jinhye Bae\, UC San Diego\nDepartment of NanoEngineering & Materials Science and Engineering\nSponsored by the Golden Gate Polymer Forum (GGPF)\n6:00-7:00pm\, Online via Zoom\, Free/$5 Donation\, Registration required\n\nAbstract: The design and fabrication of stimuli-responsive hydrogels and hybrids with reversible shape morphing and tunable actuation speed have been of great interest. In this talk\, I will discuss our recent progress in approaches to integrate functional materials (e.g. graphene oxide\, nanoclay\, etc.) into stimuli-responsive hydrogels (e.g. poly(N-isopropylacrylamide)). These approaches provide insights into how the presence of functional additives and physical interactions between the additives and hydrogel networks can lead to different internal structures\, and thus mechanical properties. Next\, I will describe how we have leveraged these insights to precisely program the 3D shapes and control the swelling-deswelling kinetics by external stimuli\, and tune the mechanical properties. Lastly\, I will also demonstrate how different manufacturing processes can affect the microstructures and properties of hydrogels and their hybrids. Such a systemic approach to stimuli-responsive shape morphing systems of hydrogels and hybrids will allow us to understand their structure-property relationships and utilize these systems for applications ranging from soft robotics to biomedical devices. \nSpeaker background: Jinhye Bae is an Assistant Professor in the Department of NanoEngineering at the University of California\, San Diego. She received her Ph.D. in Polymer Science and Engineering at the University of Massachusetts\, Amherst\, then worked in the School of Engineering and Applied Sciences at Harvard University as a Postdoctoral Fellow. Her research focuses on understanding the structure-property relationship of polymeric materials to program their shape reconfiguration and responsiveness. Her research interests also include the integration of material characteristics into new structural design and fabrication approaches for applications in biomedical devices\, soft robotics\, actuators\, and sensors. She has received several awards including the ACS PMSE Young Investigator Award (2023)\, the AIChE President Young Investigator Award (2021)\, and the ACS PRF Doctoral New Investigator Award (2021)\, She also has been selected as the Emerging Investigator in Nanoscale (2023)\, Soft Matter (2022)\, and Polymer Chemistry (2020).

SUMMARY:SLAC Public Lecture: Faster! Catching up to Electrons on the Move (Hybrid Event)
DESCRIPTION:Sponsored by SLAC National Accelerator Laboratory7:00-8:00pm\, Free\, Registration required to attend in-person (SLAC National Accelerator Laboratory\, Kavli Auditorium\, 2575 Sand Hill Rd\, Menlo Park\, CA 94025) or Watch Live on SLAC National Accelerator Laboratory’s YouTube Channel | Learn more  \nAbstract: Electrons are tiny particles that hold together the atoms in molecules. When sunlight interacts with a molecule\, it first transfers its energy to the electrons.  Then\, as the electrons move\, the molecule changes form\, reshaping itself or even breaking apart.  We do not fully understand how electrons affect the molecules to which they belong because it is very hard to catch them in action.  Electrons move incredibly quickly\, and they behave according to the peculiar laws of quantum mechanics.  But now\, we can follow the motion of electrons using SLAC’s Linac Coherent Light Source\, an accelerator that can make pulses of X-rays that are shorter than one millionth of a billionth of a second.  In this lecture\, I will explain how this one-of-a-kind tool allows us to watch speedy electrons as they move. \n \nAbout the Speaker: Taran Driver is an Associate Staff Scientist at the Linac Coherent Light Source (LCLS) and the Stanford PULSE Institute. He grew up in the United Kingdom\, where he obtained his B.Sc. in physics and philosophy from the University of Nottingham in 2014\, and his Ph.D. in biomolecular structure analysis from Imperial College London in 2019. He came to SLAC in 2019 as a postdoctoral scholar at the Stanford PULSE Institute. His research at SLAC focuses on using the unique ultrashort X-ray pulses made by the LCLS to understand how electrons move within molecules. In his spare time\, he enjoys cycling and playing soccer in the California sunshine. \nSee also: Taran Driver wins 2023 LCLS Young Investigator Award for work on capturing ultrafast electron movements (SLAC News\, October 20\, 2023)
