SUMMARY:Polyelectrolyte Complex Scaffoldings for Wet Adhesives and 3D Bioprinting Inks
DESCRIPTION:Prof. Samanvaya Srivastava\, UCLA Chemical & Biomolecular Engineering\nSponsored by Golden Gate Polymer Forum (GGPF)\n6:00-7:00 pm\, Online\, Free\, Registration required by 1:00 pm on January 15th\n\n“Photocrosslinkable precursors (small molecules or polymers) undergo rapid crosslinking upon photoirradiation\, forming covalently crosslinked hydrogels. The spatiotemporally controlled crosslinking\, which can be achieved in situ\, encourages the utility of photocrosslinked hydrogels in biomedicine as bioadhesives\, bioprinting inks\, and extracellular matrix mimics. However\, the low viscosity of the precursor solutions results in handling difficulties owing to unwanted flows and dilution\, and compromises the strength of the photocrosslinked hydrogels. In this talk\, I will introduce oppositely charged triblock polyelectrolytes as additives for precursor solutions that transform the precursor solution into a self-assembled polyelectrolyte complex (PEC) hydrogel with enhanced shear strength and viscosity\, providing interim protection against precursor dilution and mitigating secondary flows. The PEC network also augments the properties of the photocrosslinked hydrogels. Crosslinking of the precursors upon photoirradiation results in the formation of interpenetrating polymer network hydrogels with both PEC and covalently-linked networks that exhibit shear moduli exceeding the linear combination of the moduli of the constituent networks and overcome the tensile strength–extensibility tradeoff that restricts the performance of covalently-linked hydrogels. The reinforcement approach will be shown to be broadly compatible with photocrosslinkable precursors\, not require any modification of the precursors\, and introduce minimal processing steps\, paving the way for broader translation of photocrosslinkable materials for biomedical applications. \nSpeaker Background \n\nSamanvaya is an Associate Professor of Chemical and Biomolecular Engineering at UCLA. He completed his undergraduate and master’s degrees from IIT Kanpur and his Ph.D. from Cornell University\, all in Chemical Engineering. At IIT Kanpur\, he worked with Prof. Ashutosh Sharma on instabilities in thin films. At Cornell\, he worked with Prof. Lynden Archer on the structure and properties of polymer nanocomposites and nanoparticle dispersions. After his Ph.D.\, Samanvaya pursued postdoctoral research on polyelectrolyte solutions and complexes with Prof. Matthew Tirrell at The University of Chicago. Samanvaya’s current research interests are in investigating the influence of diverse intermolecular interactions on material structure and properties\, with a broader aim to combine this fundamental understanding with molecular engineering and self-assembly processes to improve materials design. He has published over 50 research articles and has received several awards\, including the Austin Hooey Graduate Research Excellence Recognition Award at Cornell University\, the RSC Researcher Mobility Grant\, the AIChE 35 under 35 award\, the NSF CAREER Award\, and the ACS PMSE Young Investigator Award.” \nLab website: https://www.srivastava-lab.net/

SUMMARY:Investigating Plant Terpenoid Metabolism and Bioproduct Applications
DESCRIPTION:Prof. Philipp Zerbe\, UC Davis\nSponsored by California ACS Local Section\n11:30 am-2:00 pm\, Hybrid Event: In-person $20 for lunch reservation ($10 students) at North Berkeley Senior Center\, 1901 Hearst Ave\, Berkeley. Online free\, Learn more and register | Download flyer\n\n“Join us on Sunday\, January 19\, 2025 for a buffet lunch\, networking\, and a chance to explore the exotic chemistry of plants.  Professor Philipp Zerbe will present new results from his laboratory at UC Davis\, including their studies of the scent compounds from the Wollemi Pine (shown above).  This ancient species dates to the era of the dinosaurs\, and was thought to be extinct until its discovery in the remote mountains of New South Wales\, Australia in 1994.  Its survival in the wild is threatened\, and the UCB Botanical Garden is one of many centers working to preserve the species.  Professor Zerbe is working with researchers at the Botanical Garden to study the unique chemistry of this mysterious plant. \nLunch Reservations (12:00 PM) – Please Click Here\nIf you can’t join us in-person\, you can still join us online! \nRegister for the Zoom Meeting at 1:00 PM – Click Here\nWe look forward to seeing you on January 19th! \nDownload the event flier HERE. \nAbstract\nPlants are nature’s master chemists; they deploy complex networks of specialized metabolites to interact with other organisms and adapt to their environment. Among these metabolites\, terpenoids encompass the largest class with critical functions in plant development\, chemical ecology and stress adaptation. Terpenoid chemical diversity also offers a rich source for bioproducts\, including flavors\, fragrances\, pharmaceuticals and more. A deeper understanding of the mechanisms underlying the diversity of plant terpenoid metabolism can offer innovative avenues toward agricultural and other industrial applications. Toward this vision\, the Zerbe Lab integrates functional genomics\, metabolomics and various protein biochemical and genetic appraoches to investigate the biosynthesis and physiological function of terpenoids in food\, bioenergy\, and medicinal plants. We will discuss the discovery of common and species-specific terpenoid pathways across different plant species that provide new insights into the evolutionary divergence of terpenoid metabolism\, its role in plant-environment interactions\, and how this knowledge can be applied toward crop improvement and bioproduct engineering. \nAbout the Speaker\nPhilipp Zerbe is a Professor at the Department of Plant Biology\, University of California at Davis. His research group focuses on the discovery and engineering of specialized terpenoid metabolism in food\, bioenergy and medicinal plants. For his research\, Dr. Zerbe received the 2015 Arthur Neish Young Investigator Award\, a 2016/17 Hellman Fellowship\, and 2018 Elsevier Young Investigator Award. Prior to his position at UC Davis\, Dr. Zerbe received his PhD from the Ruhr-University Bochum\, Germany (2007) with emphasis on structure-function studies plant hormone metabolism\, followed by positions as a Postdoctoral Fellow and Research Associate at the University of British Columbia (Vancouver\, Canada) where he focused his research on the discovery of terpenoid metabolism with relevance for bioproducts and stress tolerance in food crops and forest trees.”

SUMMARY:Microbes Mining Minerals: A New Route to Plant Cultivation
DESCRIPTION:Dr. Jocelyn Richardson\nSponsored by SLAC National Accelerator Laboratory\n7:00-8:00 pm\, Hybrid Event\, Free\, Learn more and Register\n\n\n\n\n\nRegister to watch in person in the Kavli Auditorium\, or watch the lecture live on our YouTube page.  \n“Plants supply us with food\, clothing\, medicines\, fuels\, and other necessities of life.  For their growth\, plants need essential minerals from the soil. These nutrients can be provided by fertilizers\, but over-fertilization can damage the environment. Is there another way? Many of the nutrients plants need to grow already exist in soil\, but they are locked up within soil minerals and inaccessible to plants. However\, there is a world of microbes within the soil that are capable of ‘mining’ critical nutrients from soil minerals to provide nutrients for themselves and can also transfer these nutrients to plants. Studying the interactions between soil minerals\, microbes and plant roots is difficult because soil is complex\, messy\, and opaque. But now it is possible\, using X-rays\, to observe the processes by which soil microbes extract\, absorb\, and transfer nutrients. In this lecture\, I will describe our studies of fungal networks extracting nutrients from soil and bacteria that assist plant growth\, preventing the build-up of harmful chemicals. This research is providing fresh insights into nourishing the growth of plants. \n\n\n\n\nAbout Jocelyn Richardson\nJocelyn Richardson grew up in Edinburgh\, Scotland\, and earned her undergraduate degree in geology from the University of St. Andrews. In 2014\, she crossed the Atlantic to begin her graduate studies in Earth and planetary sciences at Washington University in St. Louis. Some of her graduate research was conducted at X-ray synchrotrons at the national laboratories\, sparking her interest in the exciting science that these facilities could provide. After obtaining her Ph.D. in 2019\, she began a postdoctoral fellowship at SLAC\, at the Stanford Synchrotron Radiation Lightsource (SSRL)\, where she helped researchers access advanced tools for their biological studies. Jocelyn is now an Associate Staff Scientist at SSRL\, using these tools for studies at the interface of biology\, geology\, and environmental science that aim to improve our understanding of Earth’s life-support systems.”
