The Ephraim and Wilma Shaw Roseman Seminar Series presents Professor Omar Farha

Remsen Hall 233

Professor Omar Farha, Northwestern University "Smart and Programmable Crystalline Sponges for Protection From Bench to Market" Abstract: Metal-Organic Frameworks (MOFs) are a class of porous, crystalline materials composed of metal-based nodes and organic ligands that self-assemble into multi-dimensional lattices. In contrast to conventional porous materials such as zeolites and activated carbon, an abundantly diverse set […]

Postponed: Special Seminar Professor Eric Gale

Remsen 233

Massachusetts General Hospital, Harvard University Abstract: In aqueous solution, iron (Fe) can adopt different oxidation states and engage in diverse chemical speciation with discrete complexes exhibiting distinct magnetic properties. We are capitalizing on this rich chemistry to develop magnetic resonance (MR) imaging probes to noninvasively detect, map, and quantify pathologic processes occurring at cell and molecular […]

The Ephraim and Wilma Shaw Roseman Seminar Series presents Professor Alexander Sokolov

Remsen Hall 233

Professor Alexander Sokolov, Ohio State University "Harnessing the Power of Perturbation Theory for Accurate Spectroscopic Simulations of Molecules and Materials" Abstract: Accurate and affordable simulation of how molecules and materials interact with light remains one of the greatest challenges in theoretical chemistry. Modeling photochemical reactions requires quantum mechanical description of the electronic structure in ground […]

The Ephraim and Wilma Shaw Roseman Seminar Series presents Professor William Glover (Virtual)

Remsen Hall 233

Professor William Glover, NYU-ECNU Center for Computational Chemistry at NYU Shanghai "Pushing boundaries: simulations of solvent-supported electronic states" Abstract: Three pillars of theoretical chemistry are quantum mechanics (governing the physics oflight particles, especially electrons), statistical mechanics (providing the connections betweenmicroscopic interactions and macroscopic observables), and chemical dynamics (describing themotions of atoms on potential energy surfaces). […]

Special Seminar

Remsen Hall 233

Professor Melissa Zastrow, University of Houston Illuminating metal ions in the gut microbiota Abstract: Essential metal ions like zinc, copper, and iron have a broad range of signaling, stabilizing, and catalytic functions across all living systems. The gut microbiota typically acquires these metals through the host diet but must be able to adapt to dietary […]

The Ephraim and Wilma Shaw Roseman Seminar Series presents Professor Mohammad Seyedsayamdost

Remsen Hall 233

Professor Mohammad Seyedsayamdost, Princeton University "Natural Product Discovery and Biosynthesis in the Post-genomic Era" Abstract: Microbial natural products have served as a dominant source of pharmaceutical agents and comprise some of our most celebrated cures. Until the turn of the century, they were identified via tedious 'grind-and-find' approaches, increasingly leading to the re-isolation of old […]

The Ephraim and Wilma Shaw Roseman Seminar Series professor Elizabeth Elacqua (Virtual)

Professor Elizabeth Elacqua, PennState University "Merging Organic Synthetic and Polymer Chemistry: Toward Accelerated Catalysis, Sequence Definition, and Architecturally-Diverse Sp3-Enriched Polymers" Abstract: Efforts to develop synthetic methods that achieve robust materials (e.g., sequenced organic electronics, polymerizable renewable feedstocks, and/or sustainable cooperative catalysis) have generated a need to engineer strategies that merge organic synthesis and polymer chemistry to address grand challenges. Our group’s research is inspired by […]

The Ephraim and Wilma Shaw Roseman Seminar Series presents Professor Luisa Whittaker-Brooks

Remsen Hall 233

Professor Luisa Whittaker-Brooks, University of Utah "Chirality-, Ionic-, and Spin- induced electronic transfer in organometal halide semiconductors"  Abstract: Organometal halide semiconductors (OMHS) while highly desirable for a host of applications, present several challenges that remain unresolved, including the ability to control the assembly of the organic and inorganic components and interfaces at the molecular level […]

The Ephraim and Wilma Shaw Roseman Seminar Series presents Professor Justin Caram

Remsen Hall 233

**CANCELLED - RESCHEDULED DATE AND TIME WILL BE ANNOUNCED SOON** Professor Justin Caram, University of California, Los Angeles "Exploring the extremes of excitonic photophysics" Abstract: We investigate the chemical physics that underpins “extreme” excitonic photophysics -- materials with infrared electronic absorption, long-range exciton delocalization/transport, unusually narrow linewidths, and quantum functionality.  In this talk, I will […]

Special Seminar

Remsen Hall 233

Dr. Ellen Matson, University of Rochester Charge Compensation and Transfer in Molecular Metal Oxides ABSTRACT: Atomistic understanding of charge transfer processes at redox active transition metal oxide surfaces are central to the development of large-scale energy storage and conversion technologies. Here, we describe our efforts in bridge the conceptual disconnect between molecular and solid-state cation-coupled […]

The Ephraim and Wilma Shaw Roseman Seminar Series presents Associate Professor Mark Wilson

Associate Professor Mark Wilson, University of Toronto “Advancing nanocrystal-sensitized, triplet-fusion upconversion (photochemistry)” The ability to efficiently up-convert broadband, low-intensity light would be an enabling technology for volumetric 3D printing, background-free biomedical imaging, and sensitizing silicon-based cameras to the short-wave infrared. Our approach uses colloidal quantum dots to absorb low-energy photons and sensitize the spin-triplet excitonic […]

The Ephraim and Wilma Shaw Roseman Seminar Series presents Professor Matthias Heyden

Remsen Hall 233

Professor Matthias Heyden, Arizona State University “Making Sense of the “Jiggling and Wiggling of Atoms” in Molecular Simulations” Vibrational spectroscopies at mid-infrared frequencies provide excellent probes to characterize functional groups and their immediate chemical environment. However, from a thermodynamic and dynamic point of view, only the ground state of these vibrations is significantly populated at […]
