Zhou, Min (Texas A&M University, 2005-02-17)Isolated from marine sponges, many bromopyrrole alkaloids have become natural products of intense scientific interest. The oroidin-derived class of dimeric bromopyrrole alkaloids that include ageliferin, bromoageliferin, ...
-
Blanda, Michael T. (Texas A&M University. Libraries, 1989)A family of synthetic host molecules have been prepared, ranging in structural complexity from spiro-annelated monocycles 16 to symmetric bicycles 12 and ditopic tricycles 14. The neutral host molecules contain either two ...
-
Morris, Kay A. (2011-10-21)Natural products continue to inspire synthetic chemists to develop novel methodologies to provide efficient and expedient syntheses of the target molecules. Haterumalide NA aroused our interest and prompted development of ...
-
Hatfield, Susan Elizabeth (2009-05-15)Triazine chemistry has many applications from industrial usage, such as melamine resins, to academic interests in dendritic structures which may one day come to fruition as pharmaceutically applicable molecules. Organic ...

Bergbreiter, David E.; Zhou, Yuefen; Mariagnanam, Vimala M. (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1998-07-21)Present invention provides a new class of polymeric materials having utility in the formation of self assembled polymer layers on a pretreated metallic substrate. The polymeric materials are copolymers and terpolymers of ...

Vazquez, Mariela (2022-12-13)Understanding of structure-function relationships is of vital importance to produce optimum materials for progression in the microelectronics and tribological fields. This dissertation focuses on the fundamental studies ...
-
Allen, Ainsley Larue (2012-07-16)Poly(N-isopropylacrylamide) (PNIPAM), a temperature responsive polymer, undergoes a phase change at a lower critical solution temperature (LCST) in aqueous solutions. For PNIPAM this temperature is 32 °C in water. Below ...
-
Gonzalez, Sergio Omar (Texas A&M University, 2005-02-17)Most new fields in chemistry usually began as a curiosity by the researchers, followed by an intrinsic interest in basic biological, physical and chemical properties of reactions, interactions, structural features, and ...
-
Mintzer, Meredith Ann (2011-02-22)The interest in using gene therapy to target a variety of both inherited and acquired diseases has intensified over the last two decades. Because free DNA is easily degraded by serum nucleases in the bloodstream, the ...
-
Grill, Joseph Michael (2009-06-02)A review of metal-mediated epoxidation is given. Jacobsen's catalyst and the Sharpless asymmetric epoxidation catalyst are discussed. The origins of enantioselectivity are explained using stereochemical models. Several new ...
-
Li, Chunmei (Texas A&M University, 2004-09-30)Soluble polymers as supports are gaining more attention now. Developing new polymers, new reagents and catalysts, new separation systems are thus of great interest as these sorts of materials' applications in synthesis and ...
-
Lynch, Thomas . (Texas A&M University. Libraries, 1981)Lithium di-n-butyl(tri-n-butylphosphine)argentate(I) (2) and other organoargentate(I) complexes have been prepared and their mechanism of thermal decomposition studied. Chemical characterization of 2 by reaction first with ...
-
Ilg, Andrea Diane (2009-05-15)Today, there is a great need for polymers made from biorenewable resources due to the increasing price and diminishing supplies of petroleum and the overabundance of plastic waste in landfills. Polyoxymethylene can be ...
-
Smith, Jon Kirk (Texas A&M University. Libraries, 1986)The regioselectivity in the deprotonation of ketimines was examined. The studies examined the effect of the base, the deprotonation temperature and the nitrogen substituent on the formation of azaallyllithium reagents from ...
-
Pederson, Richard Lawrence (Texas A&M University. Libraries, 1990)Several aspects of the use of enzymes in organic synthesis have been explored. Fructose-1,6-diphosphate aldolase (FDP aldolase) is available commercially and has been cloned and overexpressed in E. coli. Both aldolases ...
-
Christian, Chad F. (2009-05-15)Unfortunately, chemists can never experimentally unravel a full reaction pathway. Even our ability to define key aspects of mechanisms, such as short-lived intermediates and the even more ephemeral transition states, is ...
-
Lazar, Simone T. (2020-03-04)Polymeric materials are widely used in every day applications, despite being highly flammable. In an effort to decrease the flammability of these materials, environmentally-benign nanocoatings have been deposited on common ...
