This talk will review two highly practical X-ray techniques for thin film characterization: grazing-incidence X-ray diffraction (GIXRD) and X-ray reflectivity (XRR) on […]

Seminar Abstract: Cannabis sativa is a widely distributed plant with a lengthy history of attention by humanity. Despite this long-standing interest and the accompanying extensive use and consumption plus a substantial scholarly study, the broad and detailed chemistry of the plant and its chemical components are incompletely understood even by many of its modern practitioners. […]

Lithium salts have remained the gold standard pharmacological treatment for bipolar disorder for over seventy years, yet the mechanistic basis of their therapeutic action is unknown. A central barrier to mechanistic investigation is the absence of chemical tools capable of delivering Li+ with spatial and temporal precision — current dosing is systemic, providing no means […]

Seminar Abstract: To address the plastics waste crisis, significant efforts have been directed towards the design and/or use of inherently recyclable polymers with competitive properties. However, industrial adoption of these materials remains challenging due to their expense and practicality. For this reason, in addition to the necessary mitigation of current plastic pollution, it is important […]

Seminar Abstract: Frustrated Radical Pairs (FRPs) are an emerging strategy for harnessing controlled single-electron reactivity via sterically or electronically mismatched donor-acceptor pairs. Unlike traditional two-electron Frustrated Lewis Pairs (FLPs), FRPs generate open-shell intermediates under mild, metal-free conditions. This creates new opportunities for selective bond formation. However, their use in carbon functionalization remains largely underexplored. This […]

Seminar Abstract: Amines are among the most prevalent functional group encountered in biologically active molecules and synthetic chemistry. Traditionally treated as synthetic end points, amines have recently emerged as valuable alkyl radical precursors. Central to these transformations is activation of the nitrogen center to reduce the Csp3–N bond dissociation energy. One activation strategy involves the […]

Seminar Abstract: Organosulfonium salts have recently seen an increase in utility as a handle towards a wide variety of powerful synthetic transformations. This is highlighted by the reactivity of thianthrenium salts and derivatives across transition-metal (TM) catalysis, photochemistry, electrochemistry, and radical polar crossover (RPC) reactions. Aryl sulfonium salt synthesis (e.g., thianthrenium and phenothiazinium species) has […]

Seminar Abstract: Ternary copper chalcogenide semiconductors can offer promising optoelectronic properties, but their performance is often hampered by crystallographic defects that are difficult to identify with standard laboratory characterization. This seminar explores the relationship between synthetic pathways and atomic-scale disorder in two ternary copper selenide materials, Cu3PSe4 and Cu2SiSe3. We first look at the structural […]

Seminar Abstract: Machine learning (ML) models have emerged as powerful tools for scientific discovery. Leveraging modern computing hardware allows for the generation of large data sets which can be used to train accurate, generalizable models to predict the physico-chemical behavior of molecular systems. However, the predictive power of such models is bounded by how chemical […]
