SUMMARY:Chemical Vapor Deposition Techniques for Design & Synthesis of Polymer Nanomaterials
DESCRIPTION:Prof. Rong Yang\, Chemical & Biomolecular Engineering\, Cornell University \nSponsored by the Golden Gate Polymer Forum\, GGPF\n5PM Pacific time\, Online via Zoom\, Registration required (Registration deadline: Sept. 6th @ 1pm)\n\nAbstract\nPolymers are some of the most prevalent materials in the modern age. While they have been predominantly synthesized in solution and processed into a variety of macroscopic sizes and shapes\, the need for programmability in microscopic morphology has challenged traditional synthesis approaches. Recent advances in vacuum-based synthesis technologies\, such as initiated Chemical Vapor Deposition (iCVD) and Condensed Droplet Polymerization (CDP)\, have enabled a new mode of control over material properties during polymerization. Distinct from prior research that has placed a strong emphasis on the design of monomer molecular structure and controlled polymerization\, the all-dry synthesis methods enable manipulation of the molecular interactions\, such as nanoscale dewetting\, molecular complexation\, and long-range molecular ordering\, to achieve programmable nanoscale structures. In this talk\, we will use three examples to illustrate the underlying principles and potential benefits of this distinct synthesis paradigm: (i) leveraging nanoscale dewetting of nonpolar liquids to create polymeric nanodomes with spatiotemporal resolution on the nanoscale; (ii) enabling vapor-phase molecular complexation during polymerization to achieve an unprecedented range of molecular weight\, mechanical properties\, and film morphology; and (iii) templating continuous polymerization via structured liquids. Taken together\, these advances in manipulating the physicochemical interactions during polymerization are poised to open up a new dimension in the design and synthesis of programmable polymeric materials\, benefiting numerous existing and future technologies\, ranging from membrane separation to drug delivery. \nSpeaker Background\nDr. Rong Yang is an Assistant Professor at the R.F. Smith School of Chemical and Biomolecular Engineering at Cornell University and a Faculty Fellow at the Cornell Atkinson Center for Sustainability. She received her B.S. in Chemical Engineering in 2009 from Tsinghua University in Beijing\, her M.S. in Chemical Engineering Practice from MIT in 2012\, and her Ph.D. in Chemical Engineering from MIT in 2014. From 2014-2016\, she was a postdoctoral fellow at Boston Children’s Hospital and Harvard Medical School\, where she later became an Assistant Professor before joining Cornell in 2019. Her research lies at the intersection of material science and biomedical engineering\, with a focus on all-dry polymer synthesis techniques\, functional nano- or living materials with controlled morphology and reactivity\, and their application in drug delivery\, infectious disease treatment\, and environmental sustainability. Her work has been recognized by the NIH Pathway to Independence Award\, the NSF CAREER Award\, the ACS PMSE Young Investigator Award\, and the Intel® Rising Star Faculty Award\, among others. \n

SUMMARY:The Physics and Chemistry of the Atomic Nucleus
DESCRIPTION:Heather Crawford\, PhD\, Lawrence Berkeley National Laboratory (LBNL)\nSponsored by California ACS Section\n10:30am-Noon\, Online via Zoom\, Free\, Registration required\n\nAbstract\nThe atomic nucleus truly sits at the intersection of chemistry and physics – over the decades both scientific fields have laid claim to these uniquely mysterious quantum systems. I will talk in this presentation about the current state-of-the-art in nuclear science\, including the new Facility for Rare Isotope Beams\, which is opening a new era for studies of the nucleus. I’ll also discuss what we are learning each day to advance our understanding of nuclei across the Segre chart\, and through these studies\, our knowledge of the origin of the elements and isotopes we find on Earth and across the cosmos. \nAbout The Speaker\nHeather Crawford received her B.Sc. in Chemistry from Simon Fraser University\, in Burnaby\, British Columbia\, Canada.  She earned her Ph.D. in nuclear chemistry from Michigan State University\, working with Prof. Paul Mantica and studying the beta-decay properties of neutron-rich isotopes of Ca\, Sc and Ti at the National Superconducting Cyclotron Laboratory.  She then worked as a postdoctoral researcher in the nuclear structure group at Lawrence Berkeley National Laboratory (LBNL)\, before moving to an Assistant Professor of Physics position at Ohio University in Athens\, OH.  Heather then returned to LBNL as a career-track and now career staff scientist in the nuclear structure group.  She is a researcher into the structure of very neutron-rich exotic nuclei and served for 5 years as the chair of the Facility for Rare Isotope Beams (FRIB) Users executive committee\, representing a user’s group of 1400+ scientists. \nRSVP here!\nZoom link to be shared with attendees the day of the event. \nPlease register before Thursday\, September 14\, 2023\, 12 noon. Your email address is needed to send the Zoom link\, which will be shared with attendees on or before the day of the event via Brown Paper Tickets. \nPlease visit the CalACS website www.calacs.org to register for this meeting or use Brown Paper Tickets. \nThe event is FREE and open to the community.
