Spring 2022
Enhancing our understanding of the local structure and dynamics for different components within a biological system is key to unraveling their overall function. Nuclear magnetic resonance (NMR) spectroscopy has become an unparalleled technique for exploring both the structure and dynamics within...

Climate and air quality impacts of boreal wildfires — new analytical approaches for the investigation of light absorption and atmospheric reactivity of wildfire particulate matter
DownloadSpring 2022
Wildfire smoke emissions contain substantial amounts of light-absorbing aerosols that can affect the radiation and cloud processes, resulting in climate impacts on regional and even global scales. The radiative impact of these light-absorbing aerosols is largely contributed by brown carbon (BrC),...

Exploration of Microscopic Structure and Dynamics in Halide Perovskite and Perovskite−Inspired Materials with Solid-State NMR Spectroscopy
DownloadSpring 2022
The work presented in this thesis describes the synthesis, structure, and optical properties of three different classes of halide-based perovskite materials, namely, metal halide perovskites of ABX3 type, halide double perovskites of A2B'B"X6 type, and “vacancy-ordered perovskites” of A2BX6 type...

Investigation of banglenes as neurotrophic agents and development of a new fluorescent protein- based FRET pair
DownloadFall 2022
This thesis describes efforts towards understanding the neurotrophic activity of banglenes and the development of a new fluorescent protein-based FRET pair. Neurotrophic small molecule natural products are functional analogs of signaling proteins called neurotrophins, which cause a pro-growth,...

Binding Topologies of Amino Acid Binary Systems by Infrared Multiphoton Dissociation (IRMPD) Spectroscopy
DownloadSpring 2022
Studies of amino acids are essential because they are one of the building blocks of larger biomolecules, and it is crucial for us to understand how they interact with each other to fulfill all these various biological functions in our daily life. One interesting and noticeable fact from previous...

Developing strategies for improving our understanding of the air quality impacts of dust heterogeneous chemistry
DownloadSpring 2022
Dust is one of the leading contributors to particulate matter (PM) in the atmosphere and can be natural (i.e., mineral dust) and anthropogenic (i.e., road and industrial dust) in origin. Natural and anthropogenic dusts provide a reactive surface for the chemical transformation of pollutant gases,...

Fall 2022
Peptides can elicit a whole host of beneficial physiological effects. The market for peptide-based therapeutics is rapidly expanding due to their extreme specificity and low toxicity. Conversely, they often possess poor bioavailability, stability, pharmacokinetics and cell permeability, limiting...

High Resolution Rotational Spectroscopic Studies of the Dynamics and Conformations of Dispersion and Hydrogen Bonded Molecular Complexes
DownloadFall 2022
High resolution rotational spectra of non-covalently bonded molecular clusters produced in a supersonic jet expansion can provide detailed and rich information about their structure-energy relationship and dynamical behaviors. In this thesis, several non-covalently bonded molecular clusters which...

Archipelago Model Compound Synthesis by Rhodium-catalyzed Annulations of Island-tethered Alkynes with Aromatic Substrates
DownloadFall 2022
Asphaltenes are the most complex constituents in bitumen. They are distinguished from other components in bitumen by high density, high viscosity and a strong tendency to form aggregates in solutions. Asphaltene aggregates may precipitate as a result of small environmental changes, which is...

Conformations of, and Non-covalent Interactions in, binary fluoroalcohol∙∙∙1,4-dioxane aggregates: Rotational Spectroscopic and DFT studies
DownloadFall 2022
Conformations of, and non-covalent interactions in, binary aggregates of 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) and 1-phenyl-2,2,2-trilfuoroethanol (PhTFE) with 1,4-dioxane were investigated. These fluoroalcohols and 1,4-dioxane are common solvents for organic reactions. Rotational spectra of...
