SUMMARY:Chem 218 Student Exit Seminar: Michael LeClaire
DESCRIPTION:“Biophysical Characterization of Cancer-Derived Cells and Extracellular Vesicles” \nABSTRACT: Extracellular vesicles (EVs) are a class of lipid bilayer enclosed particles secreted by most mammalian cells\, and are found ubiquitously in body fluids such as plasma and cerebrospinal fluid. EVs contain molecular signatures of their secreting host cells\, and are involved in long-range intercellular communication and transfer of biomolecular cargo. There is significant potential for EVs to be used as biomarkers for specific cancers\, and their involvement in long-range intercellular communication holds promise for their use as targeted drug delivery vehicles. However\, EVs’ nanoscale size and heterogeneity (30-1000 nm) and the choice of isolation methods confound the structural\, biophysical\, and surface biochemical analysis of single vesicles. Here\, we focus on the characterization of single small extracellular vesicle (sEV) (40-160 nm) structural-mechanical properties by atomic force microscopy (AFM) and other methods. We examined the impact of isolation methods on the biophysical heterogeneity of single sEVs\, including their nanoscale morphology and the presence of co-isolates. We also investigated the structural-mechanical properties of breast cancer cell line-derived sEVs and their secreting cells\, finding that breast-cancer derived sEVs reflect the biomechanical signature of the cancer cells that secrete them\, and identify similar trends in patient plasma derived EV like particles. Finally\, we demonstrated the applicability of AFM-based single sEV analysis as an efficient tool to quantify the abundance\, structure\, and biomechanical properties of sEVs from limited volume patient cerebrospinal fluid. Overall\, this work advances the understanding of single sEV structural-mechanical properties and provides a framework to assess sEV quality and purity.

SUMMARY:Chem 278 Prof. Duan Research Group Seminar
DESCRIPTION:“Ultrathin Wavy Nanowires as Highly Efficient Anode Electrocatalysts for Fuel Cell Application” \nAbstract: Direct alcohol fuel cells (DAFCs) are of tremendous interests for their higher volumetric energy density\, safer storage\, transport\, and lower cost vs. hydrogen. However\, the anode alcohol oxidation reactions are less kinetically favorable and require noble metal based electrocatalysts\, which are costly and limits the widespread adoption. Therefore\, an important challenge is to develop highly efficient electrocatalysts with high mass activity (MA) to lower the required amount of noble metal and the overall cost. Ultrathin wavy nanowires represent a class of attractive electrocatalysts with high specific surface area\, rich catalytic hotspots and excellent charge transport. In this talk\, I will discuss my effort in the design\, synthesis and characterizations of the ultrathin Rh wavy nanowires and ultrathin alloy Pt3Ag wavy nanowires as highly effective electrocatalysts for the alcohol oxidation reactions\, by considering the most fundamental design criteria to simultaneously improve the specific activity (SA) and the electrochemical active surface area (ECSA). In addition\, I will briefly discuss my ongoing effort to extend this system to Rh/Ni(OH)2 wavy nanowires and high entropy alloy wavy nanowires for the oxidation reactions of alcohols and hydrazine.

SUMMARY:Chemical Synthesis and Study of Noncanonical Membrane Lipids
DESCRIPTION:Lipid membranes are universal features of living systems\, constituting inner and outer barriers of a biological construct and maintaining non-equilibrium states necessary for life. Evolution has produced a fascinating array of lipid structures that dictate the function of biological membranes\, and organisms devote considerable energy to the synthesis and maintenance of such compositions. Our group has been studying some of the most exotic lipids observed to date\, representing a radical departure from the canonical hydrocarbons that dominate almost all prokaryotic and eukaryotic membranes. While minute amounts have been obtainable from natural sources for structural characterization\, pure quantities of such lipids for function-related studies have not. Our work has established strategies for accessing different classes of noncanonical membrane lipids. Success in this vein has resulted in controllable access to single enantiomers of amphiphilic molecules with routes that are flexible enough to allow for the additional production of non-natural analogues.

SUMMARY:Chem 278: Prof. Sen Zhang
DESCRIPTION:“Atomically Precise Nanocrystal Surfaces and Interfaces for Electrocatalysis” \nCatalysis at surfaces and interfaces where there exists bi- or multi-component cooperation has been identified as crucial for many processes related to energy and environmental applications. In this talk\, I will highlight such cooperative catalysis can be synthetically controlled at the surface and interface of atomically precise nanocrystals\, and can play critical roles in maximizing the benefit of oxygen-mediated energy conversion reactions: oxygen reduction reaction (ORR) for fuel cells and oxygen evolution reaction (OER) for water electrolyzer. The first example is M-Pt (M=non-precious metals) core-shell nanocrystals within which desirable/undesirable interfaces between non-precious metal M core and precious metal Pt shell were identified by theoretical calculations and were experimentally balanced by nanocrystal synthesis. The optimized core-shell nanocrystals exhibited favorable interfacial interaction through properly coupled electronic and strain effects\, leading to an enhanced electrocatalytic efficiency towards oxygen reduction reaction (ORR). In the second example\, we modulated the interaction of single-site Co\, Fe\, Ni catalytic centers and inorganic coordination environments in the surface of nanocrystals for electrochemical oxygen evolution reaction (OER). The seamless integration of controlled synthesis of nanocrystals\, operando structural/catalytic characterization\, and advanced theoretical calculation for oxygen electrocatalyst development will be discussed\, which will also be extended to other electrocatalytic processes (e.g. CO2 reduction and biomass-derived molecule upgrading).

SUMMARY:Modulating the conformation and function of disease-relevant RNA with small molecules
DESCRIPTION:Abstract: Small molecules offer a unique opportunity to target structural and regulatory elements in therapeutically relevant RNAs\, but understanding functional selectivity has been a recurrent challenge in small molecule:RNA recognition.  In particular\, RNAs tend to be more dynamic and offer less chemical functionality than proteins\, and biologically active ligands must compete with the highly abundant and highly structured RNA of the ribosome. Indeed\, the first small molecule drug targeting RNA other than the ribosome was just approved by the US FDA in August of 2020. Our recent survey of the literature revealed little more than one hundred reported chemical probes that target non-ribosomal RNA in biological systems. \nAs part of our efforts to improve small molecule targeting strategies and gain fundamental insights into small molecule:RNA recognition\, we have analyzed patterns in both RNA-biased small molecule chemical space and RNA topological space privileged for differentiation. We have applied these principles to functionally modulate conformations of 3’-triple helix of the long noncoding RNA MALAT1 as well as an enterovirus (EV71) IRES structure\, the latter in collaboration with the labs of Blanton Tolbert (Case Western Reserve University) and Gary Brewer and Mei-Ling Li (Rutgers Robert Wood Johnson Medical School). We have recently translated our success in developing an RNA-targeted antiviral for EV71 to targeting regulatory RNA in SARS-CoV-2.

SUMMARY:Mechanism-guided discovery of photocontrolled materials and reactions
DESCRIPTION:Abstract: The Kalow lab interrogates and exploits the relationship between molecular reactivity and macroscopic properties to discover polymeric materials relevant to human health and sustainability. We approach “reactivity-property” relationships bidirectionally: in reactivity-directed materials discovery\, we use synthesis and physical organic chemistry to tune reactions occurring within polymer networks. In polymer networks composed of reversible covalent bonds\, we translate changes in reactivity into macroscopic responses\, ranging from repair in self-healing elastomers to photocontrolled stiffness in adaptable hydrogels. In properties-directed reaction discovery\, we design photochemical reaction mechanisms that target desirable photophysical properties. Based on this principle\, we have discovered a catalyst-free photopolymerization to produce n-type π-conjugated polymers\, and a selective photoinduced cross-coupling of polyhalogenated dyes. Across these projects\, light provides precise\, tunable\, and noninvasive spatiotemporal control over molecular reactivity.

SUMMARY:Synthetic polypeptide-based materials for biological applications
DESCRIPTION:Abstract: As more attention is focused on biomaterials for medical applications\, synthetic polypeptides offer a useful approach towards designing novel biomimetic materials. Polypeptides are inherently biodegradable and biocompatible\, and offer wide-ranging properties seen in living systems. The peptide backbone is enzymatically degradable while their side chain functionality can be modified to create an array of stimuli-responsive materials. Here\, I will present work on unnatural amino acids incorporated into synthetic polypeptides to design new biomaterials\, including vesicles\, hydrogels\, and coacervates. Synthesis of these materials are modular and can be processed into an assortment of self-assembled macromolecular structures through secondary structure and self-assembly\, relevant for stem cell therapies\, gene and protein therapeutics\, and imaging guides\, among many other biomedical applications.

SUMMARY:Synthesis in a Boron World
DESCRIPTION:Abstract: Nature has evolved highly sophisticated machinery for organic synthesis\, many of which resemble molecular assembly-line processes. So far chemists have been able to apply this type of approach in the synthesis of peptides and oligonucleotides but in these reactions\, simple amide (C‒N) or phosphate (P‒O) bonds are created. It is much more difficult to make C‒C bonds but this is central to the discipline of organic synthesis. This difficulty is why organic synthesis is challenging and why robust\, iterative or automated methodologies have not yet emerged. \nHere\, we describe the application of iterative homologation of boronic esters using chiral lithiated carbamates and chloromethyllithium enabling us to grow carbon chains with control over both relative and absolute stereochemistry. Applications of this strategy to the synthesis of natural products will be demonstrated. In addition\, the methodology is used to answer fundamental questions about nature and the specific role of methyl substituents in carbon chains. By understanding their role\, I will show that molecules can be created with linear or helical conformations or hybrids of the two. \nFinally\, I will show new triggers for 1\,2-metalate rearrangements of boronate complexes using strain release as an additional driving force and we use this chemistry to make functionalized cyclobutanes and azetidines.

SUMMARY:OCDS Seminar: Prof. Rodney D. Priestley
DESCRIPTION:“Molecular Dynamics and Glass Formation of Nanoscopically Confined Polymer” \nMany technological advances are driven by the ongoing emergence of nanostructured polymers as the critical component to enable innovation. Yet\, from a materials design perspective\, we cannot presume that the bulk properties of polymers define their behavior when physically confined to nanoscale dimensions. This is\, in fact\, not true\, as there is now convincing evidence that the nanoscale properties of polymers\, including the glass transition temperature\, can be profoundly different from the bulk. Here\, I discuss two overarching questions in the field: 1) What are the molecular dynamics at the free surface of polymer glasses? and 2) How can we overcome the effect of confinement on the reduction in the glass transition temperature? Regarding the first question\, we introduce a time-resolved nano-creep experiment to probe the dynamics at the surface of polymer glasses. We reveal a new mode of molecular dynamic at the surface: pseudoentanglements. This phenomenon causes unentangled chains to exhibit surface mechanical response and dynamics that are characteristic of entangled polymers. For entangled chains\, the phenomenon prolongs and stiffens the entangled response. In both cases\, the breadth of the entangled response grows on cooling\, leading to a breakdown of time-temperature-superposition at the surface. Counterintuitively\, this new mode of slow surface dynamics emerges precisely because surface dynamics are accelerated relative to the bulk. Concerning the latter question\, we demonstrate that ultrathin polymer films with an ultradense brush morphology – defined with respect to approaching the maximum theoretical value of crystalline chain packing – exhibits a significant enhancement in thermal stability\, as manifested by an exceptionally high Tg and low expansivity. For instance\, a 5 nm thick polystyrene brush film exhibits a ~ 75 K increment in Tg and ~ 90 % reduction in expansivity compared to a spin-cast film of comparable thickness. Our results establish how the film morphology can overcome confinement and interfacial effects in controlling material properties\, and how this can be achieved by the dense packing and molecular ordering in the amorphous state of the ultradense brushes prepared by surface-initiated atom transfer radical polymerization in combination with a self-assembled monolayer of initiators.

SUMMARY:Synthetic biology approaches to study and exploit RNA regulation
DESCRIPTION:Abstract: RNA transcribed from the genome in the nucleus bears little resemblance to the RNA polymer it will ultimately become in the cytoplasm where it is translated into protein. Well-known processes such as capping\, splicing and polyadenylation\, as well as the recently discovered and ever-expanding list of diverse chemical modifications and editing\, significantly alter the properties and fates of a given RNA during the course of its lifetime. These alterations regulate critical aspects of RNA function such as stability\, transport\, protein binding\, and translation. Especially in mammalian systems\, these post-transcriptional gene expression regulatory processes are often a key determinant of genetic information flow. Moreover\, from an engineering and therapeutic perspective these RNA regulatory processes represent new ways to control or retune gene expression at the RNA level\, if they can be harnessed. I will present several technologies our group has developed to measure the chemical composition and localization of RNAs\, and to measure and control protein-RNA interactions with an eye toward therapeutic development.
