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 […]

Dr. Ellen Matson

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 […]

Mark Wilson

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 […]

Matthias Heyden

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 […]
