(2009-05-15)The objective of this research was to investigate the retention of arsenate (iAsV), arsenite (iAsIII), monomethyl arsenate (MMAsV) and dimethyl arsenate (DMAsV) by calcite and assess the impact of dissolved Ca2+, Mg2+, ...
-
(2012-07-16)This dissertation is written in two parts. The first pertains to polycarbonate and polyester synthesis using relatively benign processes. The synthesis of polycarbonates from the coupling of CO2 and epoxides catalyzed ...
-
(2009-05-15)Hydrogenation and dehydrogenation on Pd- and Pt- catalysts are encountered in many industrial hydrocarbon processes. The present work considers the development of catalysts and their kinetic modeling along a general and ...
-
(2011-10-21)Natural and synthetic estrogens are some of the most potent hormones detected in the environment. Agriculture fields often release higher concentrations of natural estrogens to the environment, but wastewater treatment ...
-
(Texas A&M University, 2006-08-16)Sedimentary basins can contain close to 20% by volume pore fluids that are commonly classified as brines. These fluids can become undersaturated with respect to calcite as a result of processes such as migration, dispersive ...
-
(2009-05-15)Despite a number of kinetic and spectroscopic studies, the chemical mechanisms of amine oxidation by flavoenzymes remain widely debated. The mechanisms of by Nmethyltryptophan oxidase (MTOX) and tryptophan 2-monooxygenase ...
-
(2011-02-22)Cerebral vasospasm following subarachnoid hemorrhage has high morbidity and mortality. Mathematical modeling of the progression of the condition provides insight to improve clinical treatment of patients post subarachnoid ...
-
(2022-01-18)Nature is inherently homochiral. L-DNA and L-RNA, the enantiomeric forms of native D-DNA and D-RNA respectively, do not occur naturally and are virtually bioorthogonal. Compared to common chemical modifications, L-DNA/RNA ...
-
(2009-05-15)Our ability to understand and predict the fate and transport of contaminants in natural systems is vital if we are to be successful in protecting our water resources. One important aspect of understanding chemical fate and ...

Exploration of the Interplay Between Allosteric Interactions of Phosphofructokinase From Rat Liver (2018-01-17)The key metabolic enzyme phosphofructokinase (PFK) catalyzes the phosphorylation of fructose-6-phosphate (Fru-6-P) by MgATP in the first committed step of glycolysis. PFK’s phosphorylation activity is tightly regulated by ...
-
(2023-05-01)Lithium-ion batteries (LIBs) are widely used energy storage devices in portable electronics and electric vehicles because of their high specific energy and high efficiency. However, constituent metals of LIBs such as ...

Kinetics and dynamics study on the allosteric pathway of phosphofructokinase from Escherichia coli (Texas A&M University, 2008-10-10)Phosphofructokinase from Escherichia coli (EcPFK) is allosterically regulated by MgADP and phosphoenolpyruvate (PEP), which act to activate or inhibit, respectively, by changing the substrate (Fru-6-P) affinity of the ...
-
(Texas A&M University, 2006-08-16)Acrylamide is considered a carcinogen in animals and a possible carcinogen in humans. It has been found in starch rich foods cooked at high temperatures. Vacuum frying (10 Torr) was studied as a possible alternative to ...
-
(2016-04-08)Dry reforming of methane is one of the few chemical reactions which can effectively convert carbon dioxide (CO2), a major green-house gas, into a valuable chemical precursor, syngas (a mixture of CO and H2), that can be ...
-
(2011-08-08)Unconventional nanofabrication techniques; both those which have been newly developed and those under development, had brought inexpensive, facile, yet high quality means to fabricate nanostructures that have feature sizes ...
-
(2014-08-22)When operating aberrantly, enzymes contribute to the mechanisms of many different diseases, and as such, have proven to be promising targets for the discovery of new drugs. Proteases catalyze the hydrolysis of peptide bonds ...
-
(Texas A&M University, 2004-11-15)Immobilization and detoxification of chromium in the vadose zone is made possible by the existence of an effective reductant, SO2, that exists in a gaseous form at room temperature. Experimental studies were designed to ...
-
(2012-07-16)This thesis seeks to investigate the adsorption capabilities of activated carbon and carbon nanotubes. The adsorption of methanol on both of these substances was tested for their application in a solar based refrigeration ...
-
(2012-07-16)The estimation of gas hydrate volume in closed systems such as pipelines during shut-in time has a great industrial importance. A method is presented to estimate the volume of formed or decomposed gas hydrate in closed ...
