LC-MS/MS method development for quantitative analysis of cyanogenic glycosides in elderberry and lipid peroxidation products in mice
(University of Missouri--Columbia, 2021)
Cyanogenic glycosides (CNGs) are naturally occurring plant molecules (nitrogenous plant secondary metabolites) which consist of an aglycone and a sugar moiety. Hydrogen cyanide (HCN) is released from these compounds following ...
Design and synthesis of group 8 transition metal complexes for C-C bond forming valorization of carbon dioxide
(University of Missouri--Columbia, 2023)
The abundancy of carbon dioxide (CO2) in Earth's atmosphere combined with its inexpensive cost and low toxicity has made CO2 upconversion to value added products an area of intense interest in catalysis research. While a ...
Mixed quantum-classical simulations of intersystem crossing in the exit channel and vibrational adaptive sampling configuration interaction
(University of Missouri--Columbia, 2022)
A computational study using mixed quantum-classical surface hopping simulations was performed for the reaction of O(3P) with dimethylamine and trimethylamine. These reactions produce an OH radical and while the OH radical ...
Advancing Uranium(III) reductive chemistry through hetroleptic metallocene aryloxide ligand frameworks
