SUMMARY:Special Bio-Inorganic Chemistry Seminar
DESCRIPTION:“Tuning the Reactivity Landscape of Metalloenzymes: From Active Site Modifications to Long-range Dynamic Effects” \nAbstract: Metalloenzymes rely on transition metals within the protein scaffold to perform a wide variety of molecular transformations in biology. Synthetic models of metalloenzyme intermediates\, inspired by the enzyme active site and its secondary coordination sphere\, have provided systems for studying bond-forming/breaking events in well-controlled environments. However\, recent evidence has suggested that the dynamic nature of proteins is intimately linked to enzyme function and activity\, implying a reactivity landscape that is not only dependent on the ground state thermodynamics of the active site\, but also on the long-range protein motions that orient the active site for optimum catalysis. The first part of this presentation will focus on the synthesis and reactivity of high-valent metal-oxo and metal-hydroxo corroles and corrolazines as models for reactive intermediates in Cytochrome P450. The role of electronic structure\, peripheral ligand sterics\, and Lewis acid effects on oxygen atom transfer and hydroxyl radical rebound reactivities were evaluated in the context of how the active site microenvironment tunes the reactivity of heme enzymes. The second part of the presentation will focus on our current efforts on characterizing activity-related protein motions in the non-heme enzyme soybean lipoxygenase (SLO-1). SLO-1 utilizes a well-defined hydrogen tunneling mechanism that is intrinsically dependent on the motions of the protein scaffold. Collectively\, the findings from these research efforts have led to several fundamental insights regarding how reactivity is tuned from the active site and beyond\, providing a possible blueprint for the design of efficient catalysts for biological and industrial applications.

SUMMARY:Harnessing Conformational Dynamics to Engineer New Enzymes: Prof. Lynn Kamerlin\, Uppsala University
DESCRIPTION:Harnessing Conformational Dynamics to Engineer New Enzymes\nUnderstanding how new enzyme functions evolve\, either on existing scaffolds\, or completely de novo on previously non-catalytic scaffolds\, is of great interest both from a fundamental biochemistry perspective\, and from a biotechnological perspective. Several hypotheses have been put forward to rationalize enzyme evolution\, one of which is that their conformational dynamics plays an important role in facilitating the emergence of new enzyme functions.[1-3] My team and I have invested substantial research effort into understanding enzyme multifunctionality in catalytically promiscuous enzymes\,[4-7] as well as the structure-function-dynamics relationships shaping the evolution of new enzyme functions\, in both natural and engineered active sites.[8-12] In this talk\, I will discuss recent progress in this area\, and illustrate how we have engineered conformational dynamics to generate a a de novo active site capable of catalyzing a non-natural reaction\,[9] and then subsequently enhanced this activity using a simple computational approach\, reaching catalytic efficiency comparable to that of naturally occurring enzymes.[13]   \n[1] James & Tawfik\, Trends Biochem.

SUMMARY:Chem 218 Student Exit Seminar: Victoria Basile
DESCRIPTION:“Nanostructured Nickel-Rich Cathode Materials for High-Capacity and Fast-Charging Lithium-Ion Batteries” \nABSTRACT: Fast-charging lithium-ion batteries are desired for use in personal electronics and electric vehicles\, potentially allowing systems to charge devices in minutes rather than hours. Fast-charging can be achieved by nanostructuring battery materials\, which decreases lithium-ion diffusion lengths and can suppress slow\, rate-limiting phase transitions. This method of nanostructuring battery materials to enhance fast-charging performance has been shown in many anode materials. However\, lithium-ion batteries are usually limited by the capacity of their cathodes (< 200 mAh/g). Unfortunately\, fewer fast-charging cathode materials have been identified\, and those that have been suffer from capacity loss upon nanostructuring. Here\, we studied the nickel-rich cathode material LiNi0.80Co0.15Al0.05O2 (NCA)\, which has high-capacity and shows solid-solution behavior without a phase transitions in bulk materials. Because phase transitions do not limit intercalation kinetics in bulk NCA\, materials only need to be nanostructured to decrease lithium-ion diffusion lengths to the point that solid-state diffusion is not rate limiting. Here we demonstrated the use of polymer templating\, combined with sol-gel synthesis\, to produce nanoporous NCA with medium and small particle sizes. We can then study the effect of size on the material’s electrochemical properties. Interestingly\, we found that NCA materials with medium particle sizes perform best at fast rates. Their performance is better than that of bulk materials because of their decreased lithium-ion diffusion lengths\, which allows for fast-charging. NCA materials with medium sized particles also out-perform materials with small particles\, however\, and this is because nickel-rich materials are highly air-sensitive\, and the smaller particles have higher surface areas\, leading to more undesirable reactions with air that produce insulating surface layers that can hinder lithium-ion diffusion at fast rates. These results indicate that the smallest particle sizes are not always optimal and that a balance exists between lithium-ion diffusion distances and surface reactivity for nickel-rich cathode materials.

SUMMARY:Chem 278: Prof. Michael T. Yeung
DESCRIPTION:“Metallic and Covalent Bonding in Materials: Role in Properties\, Structure\, and Stability” \n Abstract: The search for new ultraincompressible\, superhard materials has been performed largely through trial and error. Despite the difficulties in synthesizing such materials\, interest in this field has blossomed with recent experimental and theoretical results. Such progress has led to the development of superhard metal borides\, ultraincompressible nitrides\, and strong carbides. By studying the origin of strength from previously discovered ultraincompressible\, hard materials\, we hope to gain new insight into this rapidly growing field. In particular\, we propose a focus on bonding and microstructure to understand why some materials are ultraincompressible and superhard.

SUMMARY:Lessons from molecular evolution: from origin of life to phage-based nanomaterials
DESCRIPTION:Abstract: \nMolecular evolution is a walk over a fitness landscape\, in which populations explore sequence space through mutation and ‘climb’ up fitness peaks. The topography of the fitness landscape governs potential pathways for evolution and determines whether fitness can be optimized by natural selection. We are making exhaustive maps of fitness landscapes for catalytic RNA (ribozymes) by combining in vitro selection with a massively parallel kinetic assay using high-throughput sequencing. In addition\, we take advantage of the ongoing natural selection of phages in order to engineer phage-based nanomaterials for detection and killing of pathogenic bacteria. These nanomaterials combine evolutionarily optimized attachment strategies of phages with the controllable nature of nanomaterials to circumvent some obstacles to phage therapy.

SUMMARY:Chem 218: First Principles Many-Body Theory and Quantum Dynamics for Materials Prediction - Prof. Yuan Ping\, UCSC
DESCRIPTION:First Principles Many-Body Theory and Quantum Dynamics for Materials Prediction  \nMaterials prediction is the ultimate solution for ending blind experimental search within an expansive material parameter space. First-principles theory entirely based on quantum mechanics without prior input parameters is the perfect tool for new material design. In order to predict exotic quantum materials and out-of-equilibrium processes\, many-body physics and quantum kinetic theory are needed to bridge with first-principles methods. \nIn this talk\, I will discuss the past development on theory and numerical codes of solving the Bethe-Salpeter equation without explicit empty states\, for accurate prediction of optical excitation and exciton recombination. I will show the recent developments on radiative and phonon-assisted nonradiative exciton recombination in two-dimensional materials and spin defects.  Next\, I will show our recent method development on real-time quantum dynamics with coupled spins\, electrons\, photons and phonons based on first-principles density-matrix approach. This method will offer new and unbiased insights for spin relaxation and decoherence in general systems\,  and determine design rules for new quantum materials with ideal physical properties for spintronics and quantum information science.

SUMMARY:Chem 278: Dr. Evan Doud
DESCRIPTION:“Beyond Traditional Superatom Ligands and Cores” \n Abstract: As technological development continues to advance at a rapid pace\, there is an increasing need for next-generation materials. There are several fundamental challenges associated with developing these novel materials\, including understanding the nature of the electronic contacts and tuning the specific properties of a material. In the context of novel ligands and core compositions of superatoms\, this talk will first describe how Near Edge X-ray Absorption Fine Structure (NEXAFS) and X-ray Photoelectron Spectroscopy (XPS) coupled with Density Functional Theory (DFT) calculations were used to determine the geometry and structure of N-heterocyclic carbenes (NHCs) on a Au(111) surface. Followed by a demonstration of how a novel in situ reduction technique was used to probe the conductance of NHCs on the single molecule level using the Scanning Tunneling Microscopy – Break Junction (STM-BJ) technique. Finally\, the synthesis of nickel phosphinidene superatoms from the uncommon organocyclophosphine precursor will be discussed

SUMMARY:Interfacial Chemistry of Colloidal Nanocrystals to Direct Energy Conversion: Prof. Brandi Cossairt\, University of Washington
DESCRIPTION:Interfacial Chemistry of Colloidal Nanocrystals to Direct Energy Conversion \nWe are interested in developing colloidal nanocrystals for wide-ranging applications in energy interconversion. Our approach leverages the extraordinary properties of nanoscale systems and applies design principles of molecular inorganic chemistry. This talk will focus on two key research themes. First\, we will explore how interfacial chemistry can be used to control the photophysics and emissive properties of colloidal semiconductor nanocrystals. Second\, we will explore interfacial chemistry concepts to control the inner-sphere reactivity of colloidal electrocatalysts for multi-proton\, multi-electron transformations. Ligand etching\, ligand exchange\, and covalent functionalization will be presented as complementary methods to alter electrocatalytic interfaces by tuning the activity\, selectivity\, and bulk interfacial properties. Ultimately\, we are viewing nanocrystal interfaces as platforms for coordination chemistry that will direct function.

SUMMARY:Writing the rules for targeting dynamic proteins
DESCRIPTION:Abstract: Transcriptional coactivators and their partner transcription factors have been labeled as intrinsically disordered\, fuzzy\, and undruggable. We propose that the identification of conserved mechanisms of engagement between coactivators and their cognate activators should provide general principles for small-molecule modulator discovery. Towards that end\, biophysical characterization of the structurally divergent coactivator Med25 reveals that it forms short-lived and dynamic complexes with three different transcriptional activators and that conformational shifts are mediated by a flexible substructure of two dynamical helices and flanking loops. Analogous substructures are found across eukaryotic coactivators. Further\, targeting one of the flexible structures with a small molecule modulates Med25-activator complexes. Thus\, the two conclusions of the work are actionable for the discovery of small-molecule modulators of this functionally important protein class.

DESCRIPTION:“Thermodynamic and Mechanistic Studies of C02Reduction Catalysts” \n Abstract: The increase in global energy demands\, coupled with growing environmental concerns\, necessitates the development of viable technologies to store solar energy. Towards this end\, my group is focused on developing efficient catalysts that convert CO2 to CO\, methanol or formic acid. My talk will first describe our mechanistic studies on known CO2 hydrogenation catalysts\, whereby mechanistic insight is gleaned through thermochemical studies\, and allows for tuning the product selectivity. We also have uncovered a unique mechanism for CO2 hydrogenation\, whereby CO2 must first bind to the ligand before subsequent reduction occurs. I will then discuss how we have used the same thermochemical approach to study the mechanism of electrocatalytic CO2 reduction in a combined carbon capture & reduction system. Finally\, I will present a novel ligand scaffold that\, when put on Co\, allows for both the hydrogenation of CO2 to formate and the electrochemical reduction of CO2 to formate; this is unique in that no H2 is produced electrocatalytically. The collective work underscores the importance of the effective hydricity as a parameter of interest and in using thermochemical parameters to rationalize and uncover alternative mechanisms. The studies presented are contextualized in developing an understanding of how to rationally design energy-efficient CO2 reduction catalysts.

SUMMARY:Development of New Chemical Platforms for Polymer Synthesis
DESCRIPTION:Abstract: Synthetic polymers have permeated nearly every facet of modern life. From the ubiquity of polyolefins to recent advancements in 3-D printing\, organic materials continue to shape the world around us. While tremendous accomplishments have been made with relatively few polymer families\, the future requires the development of materials with increased control over structure to produce systems that can respond to programmed inputs\, as well as the exploration of entirely new polymer compositions. Our group takes a chemistry-focused approach to address these challenges through the strategic application of organic methodologies to design new monomer families and reagents for precision polymer synthesis. This presentation will specifically highlight (1) the utility of enyne chemistry to impart degradability and expedite functionalization of metathesis-derived materials and (2) the development of a new class of living polymerization that is enabled by the unusual reactivity profiles of twisted amide molecules.

SUMMARY:Chem 218: Prof. Vanessa Wood
DESCRIPTION:“Structure and Surfaces at the Nanoscale” \n Abstract: Liquid-phase and wet-processing techniques offer tremendous opportunities for low-cost manufacturing and enable the concept of large-scale nanotechnology. Today\, these approaches have facilitated the massive upscaling of lithium ion battery technology and promise to play a future role in a wide variety of electronic\, photonic\, and electrochemical systems. Materials and devices made from these approaches often exhibit hierarchical structures and have complex interfaces that are key to their performance. In this talk\, I will describe the importance of understanding structure-performance relationships to achieve the full potential of solution processed systems.  \nTo characterize structure and structural dynamics in these complex\, multiscale materials\, we leverage a wide variety of techniques including electron microscopies\, x-ray imaging\, diffraction\, and scattering\, neutron scattering and imaging\, and muon spectroscopy. Combining information from characterization with simulation and experiment\, we use our findings to understand the origins of performance limitations and develop design guidelines to systematically improve material and devices.  \nMy talk will present several examples\, including the role of nanocrystal surfaces in determining their emission linewidths\, carrier cooling\, and charge transport\, and the role of nanoscale structure and surface chemistry on electrolyte infilling in lithium ion batteries and lithium transport. I will address the experimental and computational challenges associated with studying these systems and emphasize ways machine learning techniques and systematic leveraging of size control the nanoscale can be used to overcome these challenges.

SUMMARY:Combining Theory and Experiment to Develop Selective Three-Component Fe-Catalyzed Radical Cascade/Cross-Couplings
DESCRIPTION:Abstract: Despite advances in high-throughput screening methods leading to a surge in the discovery of catalytic reactions\, our knowledge of the molecular-level interactions in the rate- and selectivity-determining steps of catalytic reactions\, especially those involving highly unstable and reactive open-shell intermediates\, is rudimentary. These knowledge gaps prevent control\, suppression or enhancement\, of competing reaction channels that can drive development of unprecedented catalytic reactions. In this talk\, I will focus on our use of high-level quantum mechanical calculations\, rigorously calibrated against experimental data\, to interrogate the mechanisms and to guide the development of new catalysts and reagents for currently sluggish or unselective reactions. In particular\, I will focus on our use of combined experimental and computational tools to understand and develop new (asymmetric) three-component iron-catalyzed radical cascade/cross-coupling reactions.
