Excited state molecular structural evolution and chemical reactivity studied by femtosecond stimulated Raman spectroscopy

Creator:: Han, Fangyuan
Abstract:: In this dissertation, my research work on excited state dynamics of small organic molecules in solutions is presented. Using femtosecond stimulated Raman spectroscopy (FSRS) as the main experimental tool, the excited state hydrogen-bonding dynamics (ESHBD) of Coumarin 102, a common laser dye molecule, in ethanol solution is examined with <150...

Organic Crystalline Solids : Investigating their Capability, Storage Mechanism and Structural Evolution in Dual-Ion Batteries

Creator:: Rodríguez Pérez, Ismael A.
Abstract:: Widespread installation of renewable energy sources, such as wind and solar, has been delayed by the lack of suitable stationary energy storage solutions. Current large-scale technologies, such as pumped hydro and compressed air, are geographically restricted. This is where electrochemical energy storage - batteries or hybrid capacitors can play a...

Tracking Photoinduced Primary Events with Femtosecond Stimulated Raman Spectroscopy and Calculations

Creator:: Wang, Yanli
Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is a powerful ultrafast technique which can track photoinduced excited state structural events on femtosecond (fs) to picosecond (ps) timescales. In addition to high temporal and spectral resolutions, FSRS provides a broad spectral window from ca. 100—2000 cm-1 for detection, enabling the direct mapping of...

Preparation and Properties of Porous Carbon Materials

Creator:: Xing, Zhenyu
Abstract:: Porous carbon is indispensable in modern technology applications. It is used for energy storage, gas separation, water purification, catalyst support, and chromatography. The diversity of its applications stems from its unique properties, including high specific surface area, tunable pore volume, and chemical stability. Specifically, the large surface area provides high...

Sorption by detached organic films and its relation to filiform corrosion

Creator:: Kennedy, George Hunt
Abstract:: The rate of interaction of carbon dioxide with eight detached organic films commonly used as coatings for metal surfaces was examined. The films studied were lacquers of several different formulations including oleoresinous, phenolic, vinyl, alkyd, epoxy, and hydrocarbon types. The sorption was measured on a McBain type gravimetric adsorption balance...

Total Synthesis of Goniomitine : Development of Aminal and α-Amino Radicals in the Synthesis of Nitrogen-Rich Natural Products

Creator:: Vellucci, Jessica K.
Abstract:: Aminal radical intermediates were generated by the method of radical translocation and reacted in C-C bond forming reactions with electronically deficient alkenes (Schiedler et al. Org. Lett. 2012, 14, 6092). Aminal radical intermediates can participate in inter- and intra-molecular reactions using both Bu3SnH and (TMS)₃SiH as hydride donors. Carbon–carbon bonds...

Bioprospecting the Chemical Diversity of Plant-associated Fungi

Creator:: González-Montiel, Gisela Abigail
Abstract:: Fungi have long been used for discovery of new chemical scaffolds. In the clinical setting, the fungal natural products penicillin, statins, and cyclosporine have revolutionized medicine to treat diseases and infections. In the environment, fungal natural products have been used as herbicides, fungicides, and insecticides to protect crops, livestock, and...

Gene Expression, Structure Elucidation, and Bioactivity of Aspergillus Natural Products

Creator:: Neuhaus, George F.
Abstract:: The study of natural products (NPs) and their application has shaped humanity. Starting with the idea of using plants as medicine, it has now grown into the science of purifying and identifying organic molecules from nature to study their inherent biological activities. Understanding the molecular structures of NPs is the...
