Structure-function relationships in dendrimer-encapsulated metal nanoparticles
(Texas A&M University, 2006-04-12)
The synthesis, characterization and structure-function
relationships of mono- and bimetallic dendrimerencapsulated
nanoparticles (DENs) are described. Control
over the factors influencing the structure of bimetallic
DENs ...
Development of environmental and oceanographic real-time assessment system for the near-shore environment
(Texas A&M University, 2006-08-16)
The coupling of real-time measurements and numerical models will be important
in overcoming the challenges in environmental and oceanographic assessments in
surface waters. Continuous monitoring will take advantage of ...
Mechanism for the hydrolysis of organophosphates and investigations into the stereoselective hydrolysis of organophosphorus Esters by Phosphotriesterase.
(Texas A&M University, 2006-04-12)
Phosphotriesterase (PTE) is a zinc metalloenzyme that catalyzes the hydrolysis of organophosphorus compounds. Metal ion roles during binding and catalysis are probed by comparing the kinetic properties of Zn/Zn, Cd/Cd, ...
N2s2 chelating agents as cys-x-cys biomimics for fe(no) and fe(no)2 complexes
(Texas A&M University, 2006-08-16)
Nitric oxide plays an important role in many biological functions. A metallo derivative in biological systems is a protein-bound dinitrosyl iron complex (DNIC), which results from iron-sulfur cluster degradation in the ...
Phase selectively soluble polymers for homogeneously supported catalysts
(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 ...
Thermal runaway reaction hazard and decomposition mechanism of the hydroxylamine system
(Texas A&M University, 2006-10-30)
Chemical reactivity hazards have posed a significant challenge for industries that
manufacture, store, and handle reactive chemicals. Without proper management and
control of reactivity, numerous incidents have caused ...
Studies on taxadiene synthase
(Texas A&M University, 2006-08-16)
Taxadiene synthase catalyzes the formation of taxadiene from GGPP, the universal building block of diterpenes. The cyclization of GGPP to taxadiene is generally thought to proceed through a series of monocyclic and bicyclic ...
Direct measurements of ensemble particle and surface interactions on homogeneous and patterned substrates
(Texas A&M University, 2006-08-16)
In this dissertation, we describe a novel method that we call Diffusing Colloidal
Probe Microscopy (DCPM), which integrates Total Internal Reflection Microscopy
(TIRM) and Video Microscopy (VM) methods to monitor three ...
Accounting scandals and stigma by association via director interlocks
(Texas A&M University, 2006-10-30)
This dissertation examines the phenomenon of stigma by association between firms in the context of corporate accounting scandals. I draw from the social psychology literature to develop a theoretical framework that supports ...
On the periphery of the periphery: household archaeology at Hacienda Tabi, Yucatan, Mexico
(Texas A&M University, 2006-10-30)
The archaeological remains at Hacienda Tabi provide an opportunity to study the
effects of large-scale societal changes on the lives of the Maya who worked on the
hacienda. The households, represented by the ruins of the ...
