SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Lior Sepunaru
DESCRIPTION:Flyer: Prof. Lior Sepunaru Flyer \nTitle: From molecular electrocatalysis to electro-assembly \nAbstract: When we think about electrochemistry\, we mostly think about batteries. However\, electrochemistry has been experiencing a renaissance in many other subdisciplines of chemistry in the last few years. In this talk\, I will introduce the concept of nanoelectrochemistry and how it is used for detecting and quantifying freely diffusing species in solution. Together we will learn how this method can help understand catalysis at the nanoscale and how this method can be used for detecting any species\, one at a time\, and by that\, learning about catalysts’ heterogeneity. After that\, I will describe our recent collaborative effort to use electricity as an external trigger to neutralize biomolecules\, altering their secondary structure and assembling them. The concept is similar to what Frankenstein tried to do with his (gentle) monster\, but we do that on a molecular scale. Overall\, the primary motivation is to share with you what electrochemistry offers beyond conventional electrical storage and power devices.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Keith Keitz
DESCRIPTION:Flyer: Prof. Keith Keitz Flyer \nTitle: Expanding Cellular Metabolism through Extracellular Electron Transfer \nAbstract: Qualities exhibited by living systems\, including self-regulation\, self-healing\, morphology control\, and environmental responsiveness\, are highly attractive from a material design perspective. However\, biological materials including biofilms and tissues are generally less robust and more difficult to engineer than synthetic materials. Bridging these seemingly disparate properties could enhance the vast functional space of engineered materials with living characteristics. Paradoxically\, such designs require methods to program genetic and transcriptional responses to control non-biological material properties. Addressing this challenge\, our lab employs techniques from microbiology\, synthetic biology\, and metabolic engineering to control extracellular electron transfer (EET)\, a form of microbial respiration in which extracellular metals and metal oxides are used as terminal electron acceptors. Using the model electroactive bacterium Shewanella oneidensis\, we coopt EET to establish metabolic and genetic control over a variety of redox-driven catalytic reactions. Specifically\, we show that S. oneidensis can activate controlled radical polymerizations to form well-defined synthetic homopolymers\, block copolymers\, and crosslink hydrogels. We also show that EET can control alternative synthetic reactions\, including Cu-catalyzed azide-alkyne cycloaddition. Finally\, we establish that these reactions can be placed under transcriptional control using genetic circuits that regulate the expression of EET-relevant electron transfer proteins. Ultimately\, our efforts demonstrate how the chemical reaction space available to bacteria can be expanded using EET and how this novel form of bacterial respiration can endow synthetic materials with the properties of living systems.

SUMMARY:Physical Chemistry Seminar 228: Prineha Narang
DESCRIPTION:Narang Flyer \nPredicting Electron Hydrodynamics and Signatures of Unconventional Transport \nAbstract: The re-invigorated field of electron hydrodynamics in quantum matter has recently garnered considerable scientific interest\, both due to its technological promise of designing near dissipation-less nanoelectronics\, as well as its fundamental importance as an experimental probe of strong electron-electron interactions. Investigating the capacity to which observations of electron hydrodynamic flows can inform the nature of electron-electron interactions is particularly important and timely with the advent of spatially-resolved transport measurements which\, having demonstrated the hallmark spatial signature of electron hydrodynamic channel flow\, must now turn their attention to studying more spatially-complex geometries\, enabling the observation of intricate fluid phenomena such as vortices. Recently we have explored the effects of crystal symmetry on electron fluid behaviors starting from the most general viscosity tensors in two and three dimensions\, constrained only by crystal symmetry and thermodynamics. In our work we demonstrate the anomalous landscape for electron hydrodynamics in systems beyond graphene\, highlighting that previously-thought exotic fluid phenomena can exist in both two-dimensional and anisotropic three-dimensional materials with or without breaking time-reversal symmetry. In this context\, the first part of my talk will discuss our recent predictions of hydrodynamics beyond graphene\, especially the role of phonons in hydrodynamics in Weyl semimetals. We identify phonon-mediated electron-electron interactions\, computed with techniques developed in the group that I will discuss in this talk\, as critical in a microscopic understanding of hydrodynamics. The second part of my talk will introduce a new theoretical and computational transport framework from our group\, the SpaRTaNS (Spatially Resolved Transport of Nonequilibrium Species) framework. I will discuss applications of this method in nonequilibrium electron and phonon transport in quantum matter. Time permitting\, building on our recent work in magnetic Weyl semimetals\, I will discuss possible approaches to understand and realize axion physics in condensed-matter systems.

SUMMARY:Houk-Jung Organic Colloquium 247: Yiming Wang
DESCRIPTION:Wang Flyer \nCationic Late Transition Metal Complexes for Selective α-C–H Functionalization \nAbstract: We describe the discovery and development of catalytic α-C–H functionalization reactions of simple unsaturated hydrocarbons\, including alkynes\, alkenes\, and allenes\, using cationic cyclopentadienyliron(II) dicarbonyl complexes. These complexes enable the development of a new mode of catalytic C–H functionalization in which metal coordination to a π-bond facilitates the deprotonation of a neighboring C–H bond. The implementation of this strategy resulted in mild\, functional group tolerant\, and regioselective transformations for the coupling of unsaturated hydrocarbons with aldehydes\, iminiums\, and other readily available or easily accessed carbon electrophiles. Investigations into the reaction mechanism and the discovery and optimization of new ligand systems are discussed.  Extensions of this approach to other transition metal catalysts for stereoselective transformations are also described.

SUMMARY:Physical Chemistry Seminar 228: Lea Nienhaus
DESCRIPTION:Neinhaus Flyer \nPhoton Transformers: Effect of Material Dimensionality on Photon Upconversion \nAbstract: Triplet generation at a hybrid inorganic/organic semiconductor interface is a very promising approach to increase the (photo-)excited state recombination lifetime\, and thus\, can facilitate energy harvesting. One of the possible applications for the generated spin-triplet excitons is photon upconversion. Photon upconversion describes the process of shortening the wavelength of the light emitted upon irradiation\, resulting in a net gain in photon energy. To comply with energy conservation laws\, triplet-triplet annihilation upconversion occurs by combining two or more low energy photons. Since direct optical excitation of triplet states is ‘spin-forbidden’\, so-called sensitizers are required to indirectly populate the triplet state by energy or charge transfer. Triplet sensitizers span a broad range of material classes including metal-organic complexes\, nanomaterials\, and bulk perovskite films. Understanding the fundamental energy transfer mechanism is crucial for the advancement of optoelectronic devices based on this process. \nThe exact triplet sensitization mechanism varies depending on several factors including: (i) the absolute alignments of the sensitizer and acceptor energy levels. (ii) The exciton binding energy in the sensitizer\, resulting in excited states in form of excitons or free carriers. (iii) Energetic polydispersity of a sample\, which varies the energetic driving force for triplet transfer. Here\, I will present the current understanding of the triplet sensitization mechanism based on sensitizer materials with different dimensionalities ranging from 0D-3D and highlight the differences of each upconversion system.

SUMMARY:Chem 263 Seminars in Chemical Biology: Prof. Mireille Kamariza
DESCRIPTION:Towards Tuberculosis control: A Trehalose-based Detection System for live Mycobacterium tuberculosis\nTuberculosis (TB) is second only to COVID-19 as the most lethal cause of death from a single infectious agent. Current primary methods for diagnosing TB infection present significant limitations such as lengthy time-to-result for phenotypic tests\, the need for a priori knowledge of Mycobacterium tuberculosis (Mtb) resistance mutations\, and prohibitive cost for molecular tests. Here\, we present fluorogenic solvatochomic trehalose probes that enables rapid detection of live Mtb. In particular\, we designed a 4-N\,N-dimethylamino-1\,8-naphthalimide–conjugated trehalose (DMN-Tre) probe that undergoes >700-fold increase in fluorescence intensity when transitioned from aqueous to hydrophobic environments. This enhancement occurs upon metabolic conversion of DMN-Tre to trehalose monomycolate and incorporation into the mycomembrane of Actinobacteria. DMN-Tre labeling enabled the rapid\, no-wash visualization of mycobacterial and corynebacterial species without nonspecific labeling of Gram-positive or Gram-negative bacteria. DMN-Tre labeling was detected within minutes and was inhibited by heat killing of mycobacteria. Furthermore\, DMN-Tre labeling was reduced by treatment with TB drugs\, unlike the clinically used auramine stain. Lastly\, DMN-Tre labeled Mtb in TB-positive human sputum samples comparably to auramine staining\, suggesting that this operationally simple method may be deployable for TB diagnosis.\nTuesday\, April 25\, 2023 | 4:00pm

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Haotian Wang
DESCRIPTION:Flyer: Dr. Haotian Wang Flyer \nTitle: Electrochemical Approaches to Decarbonizing Fuels and Chemicals \nAbstract: Electrochemical conversion of atmospheric molecules (CO2\, O2\, H2O\, N2) into fuels and chemicals represents a green and alternative route compared to traditional manufacturing approaches. However\, its practice is currently challenged at two systematic levels: the lack of active\, selective\, and stable electrocatalysts for efficient and reliable chemical bond transformations\, and the lack of novel catalytic reactors for practical reaction rates and efficient product separation. In this talk\, using CO2 reduction to gas and liquid products and O2 reduction to hydrogen peroxide as representative reactions\, I will introduce the rational design of both catalytic materials and reactors towards practical electrochemical manufacturing of fuels and chemicals.

DESCRIPTION:Bragg Flyer \nStructure-tuned Exciton Dynamics in Peptide and Electrolyte-scaffolded Molecular Assemblies \nAbstract: Electrostatic interactions and hydrogen bonding present means for driving supramolecular assembly of organic chromophores in aqueous environments and controlling the microstructures of resultant assemblies for light-harvesting applications.  We present our recent studies of the microstructure-dependence of exciton migration and electron transfer in two classes of supramolecular assemblies:  1) complexes of conjugated polyelectrolytes with electrolytic small-molecule electron acceptors; 2) assemblies of peptide-functionalized perylene diimide.  For the former\, we have determined that acceptor:donor stoichiometry and compatible head-group separations in donors and acceptors can be used to control the dominant exciton coupling of a polythiophene donor\, with significant impacts on potential for long-range charge separation and recombination.  For the later\, we demonstrate control of energy transfer by using peptide interactions to control exchange interactions of neighboring sites and thereby tune the exciton diffusion constant along molecular stacks.  We discuss potential uses of peptide-driven assembly to control inter-chromophore interactions.

SUMMARY:Special Seminar: Research in Chemical Education and STEM Pedagogy: Mr. Song Wang
DESCRIPTION:Flyer: Mr. Song Wang Flyer \nTitle: A post-structural analysis of student learning with an augmented reality molecular visualization tool in an undergraduate chemistry course \nAbstract: External representations provide an important space of learning and medium for communicating about molecular structure and function in the chemical sciences. As affordable visualization tools continue to advance\, there has been increasing interest to utilize novel technologies\, such as augmented reality (AR)\, in the development of new molecular visualization tools. However\, existing research on these visual-spatial learning tools often assumes the meaning of external representations as inherent and focuses primarily on student performance and competence\, with less attention towards how external representations take on situated meaning and potential inequity in how students participate in classroom activities that involve molecular visualization tools. In this talk\, I will describe a post-structural approach to investigate student learning with external representations that aims to address the representational practices through which external representations become increasingly meaningful and the fluid and multifaceted situations of (in)equity in an AR-mediated biochemistry group learning activity. The analysis centers around BioChemAR\, a mobile application that utilizes AR technology to create protein models for student learning. Data sources include audio and video recordings of undergraduate biochemistry students engaging with AR protein models in classroom and interview settings. Pairing qualitative analysis with quantitative metrics\, I will present a complex and nuanced story of how students learn with new forms of external representations that utilize AR technology. Findings highlight how external representations become increasingly meaningful through the (re)configuration of the material\, discursive\, and semiotic aspects of representational practices in chemistry and provide unique ways of conceptualizing equity and inequity in chemistry learning settings.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Konstantin Bukhryakov
DESCRIPTION:Flyer: Prof. Konstantin Bukhryakov Flyer \nTitle: Vanadium Alkylidenes for Olefin Metathesis \nAbstract: Olefin metathesis is a widely used synthetic method for the synthesis of chemicals employed in daily life\, including plastics\, household chemicals\, agrochemicals\, and high-grade fuels\, including biofuels from renewable\, sustainable feedstock. The current production of fine and commodity chemicals involving olefin metathesis exclusively relies on catalysts based on second- and third-row transition metals\, such as Mo\, Ru\, W\, and Re. The use of Earth-abundant first-row metal\, such as V\, will have a broad impact on society by providing less expensive and greener alternatives for existing methods. This\, in turn\, will make essential chemicals more accessible to consumers and decrease the human environmental footprint. Sustainability\, low cost\, and environmental preservation are essential but not the only driving force of our research. Thus\, V-based catalysts can offer a unique reactivity compared to second-and third-row counterparts. In my talk\, I will give an overview of our recent progress in developing V catalysts for olefin metathesis.

SUMMARY:Houk-Jung Organic Colloquium 247: Hung-Wen Liu
DESCRIPTION:Liu Flyer \nAtypical Reactions in the Biosynthesis of Herbicidins \nAbstract: Herbicidins are adenosine-derived nucleoside antibiotics with an unusual tricyclic core structure. Deletion of the genes responsible for formation of the tricyclic skeleton in Streptomyces sp. L-9-10 reveals the in vivo importance of Her4\, Her5 and Her6 during the early stages of herbicidin biosynthesis. In vitro characterization of Her4 and Her5 demonstrates their involvement in an initial\, two stage C–C coupling reaction that results in net C5′-glycosylation of ADP/ATP by UDP/TDP-glucuronic acid. Biochemical analyses and intermediate trapping experiments imply a non-canonical mechanism of C-glycosylation reminiscent of NAD-dependent S-adenosylhomocysteine hydrolase. Structural characterization of the isolated metabolites suggested possible reactions catalyzed by Her6 and Her7\, and subsequent biochemical experiments confirmed the functions of Her6 and Her7 as the C3’ epimerase and C8’ reductase\, respectively. An overall herbicidin biosynthetic pathway is thus established based on these observations.

SUMMARY:Physical Chemistry Seminar 228: Raphaele Clement
DESCRIPTION:Prof. Clement Flyer \nLinking Synthesis\, Composition\, and Performance in Li-ion and Na-ion Battery Materials Using Magnetic Resonance Tools \nAbstract: Batteries have transformed our daily lives and hold the key to a low carbon future. Yet\, current Li-ion chemistries are approaching their theoretical performance limit. Remarkably\, we continue to rely on a limited subset of Li-ion battery materials –– most commercial cathodes derive from LiCoO2 developed in 1980 –– that cannot meet our ever-growing need for energy storage. The development of more sustainable\, energy dense\, and/or safer batteries hinges on designing new cathode chemistries and crystal structures that depart from the traditional layered transition metal oxides\, as well as non flammable solid electrolytes. \nIn this talk\, I will present our recent work combining solid-state NMR\, first principles simulations\, and other advanced tools to relate synthesis\, structure\, and properties in various classes of battery materials. For example\, our work on Li-ion rocksalt oxyfluoride cathodes emphasizes the importance of 7Li/19F solid-state NMR to determine the true composition of such systems and establish robust materials design rules\, and introduces a new\, rapid and energy-efficient synthesis procedure to obtain those materials. Our work on Li- and Na-ion conducting rocksalt halide electrolytes reveals their high propensity for polymorphism and for the formation of planar defects\, with resulting structural and ion conduction properties that can be modulated by changing the synthesis conditions.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Quentin Michaudel
DESCRIPTION:Flyer: Prof. Quentin Michaudel Flyer \nTitle: Modern Organic Reactions for Precise (Macro)molecular Synthesis \nAbstract: Progress in healthcare\, clean energy\, and sustainable materials is driven by the synthesis of molecules of ever-increasing complexity. Research in the Michaudel group centers on the invention of polymerization methods that allow for precise control over macromolecular architecture (i.e.\, monomer composition\, molecular weight distribution\, stereochemistry) as a means to tailor the properties\, function\, and recyclability of soft materials. In parallel\, my group develops approaches to the functionalization of fine chemicals\, including bioactive and drug-like molecules. Our projects are grounded in fundamental mechanistic considerations with an aim to develop synthetic tools applicable to small organic compounds and macromolecules alike. This presentation will cover our recent work in SuFEx click reactions\, stereoselective olefin metathesis\, and heterocyclic aryne chemistry.

SUMMARY:Special Seminar: Research in Chemical Education and STEM Pedagogy: Dr. Jennifer Casey
DESCRIPTION:Flyer: Dr. Jennifer Casey Flyer \nTitle: Implementing Effective and Inclusive Group Work in the STEM Classroom \nAbstract: Students learn more and earn higher grades in student-centered\, collaborative instruction than in lecture-based instruction. Research also suggests that group work may improve equity in course outcomes. Given the many documented benefits of collaborative learning\, instructors have good reason to integrate group work into their classrooms\, however\, incorporating this form of active learning in large classroom settings can be difficult. Additionally\, a critical aspect is being overlooked – is incorporating group work enough\, or are specific aspects of implementation required in order to achieve a desired outcome? While the literature contains many recommendations for high-impact practices\, my work focuses on investigating which features are critical for obtaining an intended outcome\, as well as determining who truly benefits from these interventions. In this seminar\, we will specifically focus on the impact of group work on student engagement in remote chemistry classrooms\, as well as the effect group work has on student sense of belonging across multiple STEM disciplines. The picture that emerges is one that underscores the importance of having thoughtful and deliberate integration of group work into a course – preliminary data suggests having students simply work in groups is insufficient to see improved student outcomes. Depending on the overall goal an instructor is hoping to achieve\, they may need to focus on different elements of supportive group work. Furthermore\, it is important that we confirm whether the practices we are using are having the desired impact given the effort required to implement structured group work\, especially in high-enrollment courses.

SUMMARY:Jeffrey I. Zink Inorganic Chemistry Seminar Series: Jerome Robinson
DESCRIPTION:Flyer: Prof. Jerome Robinson Flyer \nTitle: Catalyst RE-Design: Dynamic\, Reactive\, and Selective Systems for Oxygenated (Co)Polymer Synthesis \nAbstract: Polymer waste has quickly become one of our society’s largest looming environmental concerns\, where an estimated 4.9 GTons of polymer waste currently exist in the environment. Central to addressing this challenge is the generation of polymers with robust materials properties that also embed or encode end-of-use. Oxygenated (co)polymers such as polyhydroxyalkanoates (PHAs) are naturally occurring and fully bioresorbable polymers with promising properties\, yet their efficient and cost-effective stereospecific synthesis remains challenging. In this talk\, I will share some of our group’s recent advances in catalyst development for the synthesis of oxygenated (co)polymers. Specifically\, we’ll discuss new catalyst design strategies which fully leverage the unique properties of the rare-earth elements (group III and the lanthanides) to generate systems which are highly dynamic\, reactive\, and selective.
