Insights on local chemical structure of chalcogenide photovoltaic materials using solid state NMR spectroscopy
DownloadSpring 2023
Quaternary chalcogenides with the formula I2-II-IV-VI4 have emerged as promising candidates for photovoltaic materials, but many details about their structures remain poorly understood. This thesis describes the synthesis, structure determination, and optical properties of the sulfides Cu2MTtS4...

Chiral Transition Metal Complexes under Resonance: Mechanism of a New Form of Chiral Raman Spectroscopy
DownloadFall 2023
My PhD thesis primarily focuses on exploring chiroptical events and signatures of chiral transition metal complexes when they are under (near) resonance conditions. To achieve this goal, multiple chiroptical spectroscopic techniques were utilized, aided by theoretical calculations. These...

Development of Chemical Isotope Labeling Liquid Chromatography Mass Spectrometry on Quadrupole-Orbitrap Mass Spectrometers for Metabolome Analysis
DownloadFall 2023
Chemical isotope labeling liquid chromatography-mass spectrometry (CIL LC-MS) is a powerful technique in metabolomics, offering extensive coverage of the metabolome. This method involves dividing metabolites into sub-groups based on their functional groups and subjecting them to specific labeling...
