Tracking Excited State Proton Transfer and Inhibition with Ultrafast Raman and Transient Absorption Spectroscopy

Creator:: Oscar, Breland G.
Abstract:: In this dissertation, excited state proton transfer (ESPT) and its inhibition in solution and protein environments are revealed using both femtosecond transient absorption (fs-TA) spectroscopy and femtosecond stimulated Raman spectroscopy (FSRS). Using a tunable Raman pump to enhance transient vibrational features of the photoacidic chromophore HPTS in methanol and methanol...

Enzymatic studies of the prenatal chick, with special reference to the multibple forms of liver soluble NADP-linked isocitric dehydrogenase

Creator:: Cheung, Geoffrey Peter
Abstract:: Levels of activity of glucose-6-phosphate- , 6-phosphogluconate- , and isocitric- dehydrogenase were measured in the soluble and particulate fractions of heart, brain and liver at several ages throughout the development of the chick embryo. Compared to isocitric dehydrogenase, levels of glucosesphosphate- , and 6-phosphogluconate- dehydrogenase are generally low. This suggests...

Synthesis of polybenzimidazoles containing arylene sulfone and ether linkages

Creator:: Cook, Diana Lynn
Abstract:: Polybenzimidazoles were synthesized from 3,3'-diaminobenzidine (DAB) and dicarboxylic acids. The polymerizations using the dicarboxylic acid monomers were carried out in polyphosphoric acid (PPA) and phosphorus pentoxide/methansulfonic acid (PPMA) which acted as the solvent and condensing agent. The resulting polybenzimidazoles had inherent viscosities in the range of 0.12 to 0.84 dL/g....

The Total Kinetic Energy Release in the Fast Neutron-induced Fission of ²³²Th

Creator:: King, Jonathan W.
Abstract:: The post-emission total kinetic energy release (TKE) in the neutron induced fission of ²³²Th was measured (using white spectrum neutrons from LANSCE) for neutron energies from En = 3 to 91 MeV. In this energy range the average post-neutron total kinetic energy release decreases from 162.3 ± 0.3 at En...

Studies on advanced intermediates in the biosynthesis of streptonigrin

Creator:: Erickson, W. Randal
Abstract:: Early studies on the biosynthesis of the quinoline quinone portion of streptonigrin, 1, had suggested the intermediacy of novel aromatic amino acids. In order to test this hypothesis, a series of compounds was synthesized and tested for potential incorporation. [4-¹⁵N] 4-Aminoanthranilic acid, 4 5 a , [4-² H] 7-aminoquinaldinic acid,...

Tuning Functional Properties of Pyrochlore and Related Oxides via Cation and Anion Substitutions

Creator:: Giampaoli, Gabriella C. S.
Abstract:: Inorganic structures play an important role in materials due to their versatility and diversity. A complete understanding of the structure of a material is vital to enhance the creation of new materials that fill voids in research. The rational design of these compounds is driven by the exploitation of structure-property...

Capturing Molecular Movies of Organic and Organometallic Systems in Solution by Ultrafast Spectroscopy

Creator:: Boulanger, Sean A.
Abstract:: Ultrafast spectroscopy can exploit the structure-function relationship of chemical- and biological-based systems. More specifically, femtosecond stimulated Raman spectroscopy (FSRS) provides ground- and excited-state vibrational information with simultaneously high spectral (spatial) and temporal resolutions. The electronic counterpart, femtosecond transient absorption (fs-TA), complements FSRS data analysis as part of a comprehensive approach...

New chemistry for electrochemical energy storage applications

Creator:: Wang, Xingfeng
Abstract:: Electrochemical capacitors and batteries are two major electrochemical energy storage technologies, which have been investigated extensively to meet the rapidly-growing demand for higher energy, higher power, lower cost and enhanced safety in the past few decades. With the charge storage mechanism of electrostatic charge adsorption desorption via electrical double layers,...

Revealing Ultrafast Dynamics and Functional Basis of Potential Biomedical Tools from Calcium Sensing to Optogenetics

Creator:: Tachibana, Sean R.
Abstract:: Photoactivated biomedical tools like fluorescent biosensors and optogenetic proteins have increased in popularity due to the precision targeting and activation used for in vivo applications. In nature, the initially discovered parent proteins exhibit properties such as fluorescence quantum yield (FQY), fluorescence color, and photoswitching dynamics that are unfavorable in mammalian...
