Mejia Mejia, Andres Fernando Fernando (2013-07-25)Many materials and biological systems in nature are suspensions composed of disks, such as clay, asphaltenes, and red blood cells. Despite their natural abundance and wide industrial application, disks are least studied ...
-
Li, Chiuping (Texas A&M University. Libraries, 1988)Precipitated iron catalysts were characterized using temperature-programmed methods, isothermal reduction, and X-ray photoelectron spectroscopy to study the influence of copper and potassium promoters on reduction behavior ...
-
Niederhoffer, Eric Car (Texas A&M University. Libraries, 1983)Autoxidation of cobalt dioxygen complexes containing 2,2'-bipyridine, 1,10-phenanthroline, and 2,2':6',2''-terpyridine in aqueous solution results in the production of simple cobalt(III) chelates and hydrogen peroxide. At ...

Cain, Amanda Ashley (2014-12-09)Halogen-additives are cost effective flame retardants (FRs) that scavenge H• and OH• radicals in the gas phase, but are under significant scrutiny due to the toxic smoke they release and their potential to leach out into ...
-
Day, Gary Allen (Texas A&M University. Libraries, 1980)The heats of K^+ - H^+ exchange have been measured calorimetrically on three samples of zirconium phosphate of widely differing crystallinity. The more crystalline exchangers both exhibit exothermic reaction over the full ...
-
Holder, Kevin Michael (2016-09-26)Layer-by-layer (LbL) assembly is a simple technique capable of building multifunctional thin films on a variety of surfaces from dilute aqueous solutions. LbL coatings on polyurethane foam have been successful in reducing ...
-
Thorstad, Melissa (2013-05-23)In 1996, scientists discovered a connection between the gene for the human protein frataxin (FXN) and the neurodegenerative disease Friedreich’s ataxia (FRDA). Decreased FXN levels result in a variety of aberrant phenotypes ...
-
Perry, Houston Phillipp (2012-02-14)The primary goal of the work described in this dissertation was the incorporation of functionality into metal phosphonates. This was done in one of several ways. The first involved using phosphonate ligands that had ...
-
Haile, Merid Minasse (2016-10-14)Layer-by-layer deposition has provided a framework in which coatings with a variety of functionality can be deposited from aqueous solutions in ambient conditions. Despite the many advantages of layer-by-layer assembly, ...
-
Mukherjee, Atashi (2014-05-30)The chemical characterization of nanomaterials in the realm of drug delivery and surface modification is on the current frontiers of analytical chemistry. A drug delivery vehicle must be able to carry therapeutic cargo and ...
-
Yakovenko, Andrey A. (2013-04-18)Synthesis of polycrystalline, vs. single-crystalline porous materials, such as metal-organic frameworks (MOFs), is usually beneficial due to shorter synthetic time and higher yields. However, the structural characterization ...
-
Feng, Dawei (2015-08-12)Metal-organic frameworks (MOFs) are a class of newly emerged porous materials. As inorganic-organic hybrid materials, MOFs exhibit many features such as crystalline structures, high surface areas, large porosities, and ...

Ayi, Ayi A.; Kinnibrugh, Tiffany L.; Clearfield, Abraham (Frontiers in Chemistry, 2014)
-
Gonzalez-Martin, Anuncia (Texas A&M University. Libraries, 1993)The presence of surface states at the p-type semiconductor/solution interface was examined by the use of three independent techniques: Scanning Tunneling Microscope (STM), Sub Band-Gap Photocurrent (SBGP) Spectroscopy, and ...
-
Wang, Guanqun (2012-07-16)Self-oscillating reactions have been widely observed and studied since the last century because they exhibit unique behaviors different from the traditional chemical reactions. Self-oscillating systems, such as the ...
-
Fewox, Christopher Sean (Texas A&M University, 2008-10-10)One model system for the investigation of selectivity in inorganic ion exchangers is a group of synthetic analogues of the mineral umbite. Hydrothermally synthesized trisilicates with the general form A2BSi3O9.H2O, where ...
