-
(Texas A&M University. Libraries, 1993)The utilization of carbon dioxide as a C1 source for the production of organic substrates presents a great challenge to researchers. One such process would be the carboxylation of hydrocarbons to afford carboxylic acids. ...
-
(2012-02-14)Density functional theory is used to study the physico-chemical effects of two metallic thin films separated by distances in a range of 4-10 amperes. In this condition, the electrons from the metallic thin film surfaces ...
-
(Texas A&M University. Libraries, 1983)The oxidation of 2,6-di-t-butylphenol by molecular oxygen in catalyzed by the (mu)-peroxo dicobalt(III) complexes formed by the ligands tetraethylenepentamine (tetren), 1,4,10,13-tetraaza-7-oxa-tridecane (taotd), ...
-
(Texas A&M University, 2006-10-30)Soluble polymer supports that could be used in thermomorphic and latent biphasic systems have been prepared and analyzed for their potential application as supports for facilitated synthesis and catalysis. Phase selective ...
-
(Texas A&M University, 2005-08-29)This dissertation focuses on bridging the pressure and complexity gap between heterogeneous catalysis and surface science by introducing new instrumental tools that can operate under catalytically relevant conditions (i.e. ...

(Texas A&M University. Libraries, 1986)The cis-M(CO)4 (13CO)PR3 [double harpoon] trans-M(CO)4(13CO)PR3 CM = Cr, R = Et; M = W, R = OMe, Me, Et, i-Pr) isomerization reactions have been studied kinetically in cyclohexane-d12 by 13C NMR spectroscopy. These ...
-
(2021-03-24)In recent years, the Bergbreiter group has investigated the use of polyisobutylene (PIB) as a selective phase anchor for catalysts and dyes into a nonpolar or alkane solvent phase. The selectivity of these polymeric supports ...

(2012-11-05)Zeolites are crystalline inorganic solids that are industrially used for adsorption, ion exchange and catalysis. As catalysts, they have been particularly successful in the hydrocarbon processing industry due to their ...
-
(Texas A&M University. Libraries, 1985)Olefins represent the starting point in the formation of the majority of the petrochemical products. The components can be polymerized, copolymerized, and selectively oxidized to a large number of useful products. As crude ...
-
(Texas A&M University. Libraries, 1986)The oxidation behavior of an alloy system with unique electronic properties and the challenge to prepare a planar model for the very active oxidation catalyst, Hopcalite, were attacked. Surface segregation phenomena of ...
-
(Texas A&M University. Libraries, 1986)Both cross-linked polystyrene and linear ethylene oligomers were investigated as supports for reagents and catalysts. Use of either of these polymers as supports, reagents or catalysts had certain advantages. Selection of ...
-
(Texas A&M University. Libraries, 1986)Ethylene oligomers having diphenylphosphine, diaryl and triaryl phosphite functional groups were used as supports for hydrogenation, hydroformylation and diene cyclooligomerization catalysts. An advantage of these ethylene ...
-
(2009-05-15)As devices and new technologies continue to shrink, nanocrystalline multi-metal compounds are becoming increasingly important for high efficiency and multifunctionality. However, synthetic methods to make desirable ...
-
(2016-08-22)The principal directions of this thesis involve (1) the synthesis and characterization of tetraphosphine linkers with rigid tetraphenylelement cores and derivatives thereof, (2) the study of the tetraphosphines and their ...
-
(Texas A&M University. Libraries, 1987)The group 6 anionic transition metal hydrides, HM(CO)4L- (M = Cr, W; L = CO, P(OMe)3 were found to be convenient reagents in organic and organometallic synthesis. These reagents offer the advantages of high selectivity, ...
