(Texas A&M University. Libraries, 1993)Alkylation of isobutane with butene is an important industrial process for producing high-octane gasoline. Current industrial alkylations use either H2SO4 or HF as a catalyst. Compared to the liquid catalyst, the use of a ...
-
(Texas A&M University. Libraries, 1987)The results of this research indicate that [M⁺O⁻] centers (M = Group IA ions) in Group IA/Group IIA oxides are responsible for the catalytic production of CH₃[superscript dot] radicals from CH₄ through hydrogen atom ...

(Texas A&M University. Libraries, 1990)With dioxygen-saturated (1 atm, 2.1 mM) dimethyl sulfoxide solutions that contain aniline (1-15 mM), the addition of excess hydroxide ion (10:1 HO-/PhNH2) yields approximately two superoxide ions (O2-), one azobenzene, and ...

(2017-07-24)Exhaust from vehicles is one of the leading contributors of particulate matter (PM) in the atmosphere. PM has been shown to be carcinogenic and to pose a significant risk to human health. Therefore, continuously stricter ...
-
(Texas A&M University. Libraries, 1992)The synthetic utilities of enzymes as catalysts for asymmetric synthesis have been explored in several aspects. Fructose-1,6-diphosphate aldolase from rabbit muscle and E. coli, rhamnulose-1-phosphate aldolase and ...
-
(Texas A&M University. Libraries, 1986)In the past five years, the search for alternative sources of petrochemical feedstocks has turned attention toward non-conventional sources of chemical carbon other than carbon monoxide. A renewed interest in the chemistry ...
-
(Texas A&M University. Libraries, 1993)This dissertation discusses the use of Lewis acids to activate and catalyze cyclization and addition reactions of aminyl radicals generated from N-hydroxypyridine-2-thione carbamates to unsaturated systems under very mild ...
-
(Texas A&M University. Libraries, 1993)Nickel complexes in sulfur-rich environments have been prepared to determine those factors which stabilize organonickel species and permit access to low valent nickel. Nickel tetrathiolate complexes were initially used as ...
-
(Texas A&M University. Libraries, 1988)The gas-phase and the catalytic oxidative dehydrogenation of ethane were studied. Lithium-promoted magnesium oxide was investigated as the catalyst. In the gas-phase oxidation study a perfectly mixed tubular reactor was ...
-
(Texas A&M University. Libraries, 1982)The selective oxidation of methanol to formaldehyde over molybdenum-containing catalysts, such as silica-supported molybdenum oxide and unsupported molybdenum oxides, was studied. This dissertation describes (1) the role ...
-
(Texas A&M University. Libraries, 1991)The formation of the amorphous phase of the Ti-Al alloy system has been carried out by co-condensation, the physical vapor deposition of the two metals, onto substrates at both ambient and liquid nitrogen temperatures. The ...

(2014-07-25)This dissertation presents the results from density functional theory (DFT) calculations on three major projects I have been working on over the past several years. The first system is focused on the structure and reactivity ...
-
(Texas A&M University. Libraries, 1993)A new, general method for the preparation of 5-aminoalkyl-furan-2(5H)-ones has been developed, and the details of the reaction have been studied. 5-Aminoalkylfuran-2(5H)-ones, which contain two chiral centers, were synthesized ...
-
(Texas A&M University. Libraries, 1992)The structure, composition and electrochemical reactivity of iodine adsorbed from aqueous iodide solutions onto Pd(111) and Pd(100) single-crystal electrodes have been investigated. Characterization of the I/Pd system ...
-
(Texas A&M University. Libraries, 1988)The intermetallic compounds of the Brewer-Engel type represent a unique case in novel heterogeneous catalyst systems. The components of these alloys are known to have altered electronic structures described as sharing of ...
