SUMMARY:Frontier Fridays: Putting Sustainable Chemistry to Work in Manufacturing
DESCRIPTION:Prof. Mark Mascal\, University of California at Davis; Prof. Ryan Lively\, Georgia Institute of Technology\nSponsored by ACS Webinars\, ACS Committee on Science\, and ACS Office of Sustainable Development\nAugusts 11\, 10-11:30am\, Online via Zoom\, Free\, Registration required\n\nBuilding a more sustainable future requires research innovations\, but equally important is translating that research into technical solutions for industrial manufacturers where it can have a practical impact. “Frontier Fridays” returns to explore the science that will revolutionize the future of the human race. \nMark Mascal at the University of California Davis (a 2022 EPA Green Chemistry Challenge Award winner) will describe his work with Origin Materials\, Inc. in developing and implementing a novel technology to replace chemicals commonly made from petroleum with products derived from forestry\, agricultural and municipal wastes. This technology could change the environmental impact of the plastics industry\, among others\, by supplying chemical feedstocks that are both net zero-carbon and recyclable. \nModern chemical manufacturing depends upon purification via chemical separations and most industrial separations are achieved with energy-intensive\, thermally driven processes (e.g.\, distillation) that account for 10-15% of global energy usage. Dr. Ryan P. Lively at Georgia Tech will describe how his research team and collaborators developed the first polymeric membranes for crude oil fractionation\, an extremely complex hydrocarbon separation process that is vital to the production of modern fuels and chemicals. This new approach could drastically reduce the energy needed for industrial separations. \nThis ACS Webinar is moderated by Adelina Voutchkova\, Director for Sustainable Development at ACS\, and is co-produced with the ACS Committee on Science and the ACS Office of Sustainable Development as part of the 2022 Frontier Fridays series. \n\n\n\n\n\nWhat You Will Learn\n\nHow biomass waste is being used to make plastics that are net zero-carbon and recyclable\nHow innovative new materials can dramatically reduce energy use for industrial separations processes\nHow innovative scientists are working with industry to put these new discoveries to work for society

SUMMARY:Extreme Mechanics of Soft Functional Materials
DESCRIPTION:Prof. Lihua Jin\, Mechanical and Aerospace Engineering\, University of California\, Los Angeles\nSponsored by the Golden Gate Polymer Forum\nAugust 16\, 6-7pm\, Online via Zoom\, Free/$5 Donation\, Registration required (Deadline Aug. 15@1pm)\n\nSoft robotics and stretchable electronics are transforming the fields of robotics and biomedical devices\, in that they are capable of sustaining large deformation and interacting safely with fragile objects and human beings. Soft functional materials\, as the building blocks of soft robotics and stretchable electronics\, are typically subjected to extreme mechanical conditions\, such as large deformation\, cyclic loading\, and fracture. In this seminar\, I will present our recent progress in modeling and charactering extreme mechanics of soft functional materials. Liquid crystal elastomers (LCEs) are special polymers combining cross-linked elastomers with rod-like liquid crystal mesogens\, aligning in a certain direction\, called the director. Combining theory and experiments\, we show that the directors of a LCE can reorient with stress in a highly rate-dependent manner. We further investigate the coupling between stress and director fields at a crack tip\, and observe significant and highly inhomogeneous director rotation\, resulting in crack-tip stress and strain distributions of LCEs distinct from those of regular elastomers. Stretchable carbon nanotube electrodes are used in various stretchable electronic devices. When deformed\, they show characteristic resistance–strain hysteresis. We use coarse-grained molecular simulations together with experiments to unravel the microstructural origin of the resistance–strain hysteresis. Finally\, we study fracture of thin conducting/semiconducting films. We have developed a new testing methodology to measure the fracture energy of free-standing ultrathin films. We further demonstrate that the fracture strain of a thin film is not an intrinsic material property\, but can be significantly augmented by tuning interfacial properties. \nSpeaker Background & Research Interests: \n\nLihua Jin is an assistant professor in the Department of Mechanical and Aerospace Engineering at the University of California\, Los Angeles (UCLA). Before joining UCLA in 2016\, she was a postdoctoral scholar at Stanford University. In 2014\, she obtained her PhD degree in Engineering Sciences from Harvard University. Prior to that\, she earned her Bachelor’s and Master’s degrees from Fudan University in 2006 and 2009. Jin’s group conducts research on mechanics of soft materials\, stimuli-responsive materials\, instability and fracture\, soft robotics\, and biomechanics. Lihua was the winner of Haythornthwaite Research Initiative Grant from American Society of Mechanical Engineers in 2016\, Extreme Mechanics Letters Young Investigator Award in 2018\, Hellman Fellowship in 2019\, UCLA Faculty Career Development Award in 2020\, and NSF CAREER Award in 2021.

SUMMARY:An Evolutionary Mystery: Mirror Asymmetry in Life and in Space (Rebroadcast)
DESCRIPTION:Brett McGuire\, National Radio Astronomy Observatory; and Ryan Fortenberry\, University of Mississippi\nSponsored by ACS Webinars and ACS Astrochemistry Subdivision\nAugust 18\, 11am-Noon PT\, Online via Zoom\, Free\, Registration required\n\nMost molecules used by life exist in two forms that are mirror images of each other. One of the great unanswered questions in our evolutionary history is why all life on Earth\, and their critical biological molecules like amino acids and proteins\, use only one “hand” of these forms. Sugars are exclusively right-handed\, amino acids are left-handed\, and even DNA coils into right-handed helices. What clues can we glean from molecules in space to discover the possible interstellar origins of this “homochirality?” \nJoin Astrochemist Brett McGuire of currently the McGuire Group at MIT to find out how chemists are using state-of-the-art tools to peer into the center of our galaxy for the answers! \n\n\n\n\n\n\nWhat You Will Learn\n\nWhat is the impact of homochirality on biology and chemical evolution\nWhat are the potential origins of homochirality and what are the challenges in studying possible interstellar origins\nWhat was the first detection of a chiral interstellar molecule and what are the challenges associated with measuring a potential chiral excess in space\n\n\n\n\n\n\n\nWebinar Details\n\nThursday\, August 18\, 2022 @ 2–3pm ET\nFree to Register with ACS ID\nSlides will be available to download on the day of the webinar

SUMMARY:How We Study Molecules in Space: Finding and Analyzing Cosmic Carbon
DESCRIPTION:Prof. Brett A. McGuire\, Massachusetts Institute of Technology; and Prof. Kyle Crabtree\, UC Davis\nSponsored by ACS Webinars and ACS Astrochemistry Subdivision\nAugust 31\, 11am-12:15pm PT\, Online via Zoom\, Free\, Registration required\nSlides will be available to download on the day of the webinar\n\nPolycyclic Aromatic Hydrocarbons (PAHs) are a large reservoir of reactive carbon in the interstellar medium that play a significant role in star and planet formation. These molecules have been observed both in our galaxy and numerous others by NASA telescopes and can even be found on Earth in engine exhaust and the char on a grilled hamburger. But what is the relationship between interstellar PAHs and those found on our planet\, and what can that tell us about the makeup of the universe? \nAstrochemist Brett McGuire of the Massachusetts Institute of Technology led the GOTHAM research collaboration that in 2021 became the first scientists to identify individual molecules of PAHs via radio observations of the Taurus molecular cloud. This breakthrough will enable astrochemists to investigate the detailed chemical pathways for the formation and destruction of these complex molecules\, which until now have only been observed en masse. Register now to discover how we study molecules in space\, why PAHs are important to both interstellar chemistry and understanding the origins of life on Earth\, and what are the current efforts to understand the chemistry of PAHs in the wake of the GOTHAM collaboration’s discovery. \nThis ACS Webinar is moderated by Kyle Crabtree of the University of California\, Davis and is co-produced by the ACS Astrochemistry Subdivision. \n\n\n\n\n\n\nWhat You Will Learn\n\nHow we study molecules in space\, including detections of PAH molecules via their rotational transitions using Green Bank Telescope observations of the Taurus Molecular Cloud (TMC-1) from the GOTHAM collaboration\nWhy Polycyclic Aromatic Hydrocarbons (PAHs) are important to interstellar chemistry\nMethods for studying the chemistry of PAHs from Earth\, including astrochemical models and laboratory spectroscopy
