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 ...
Phase selectively soluble polymer supports to facilitate homogeneous catalysis
(2009-05-15)
Soluble polymers that have phase selective solubility are useful in synthesis
because they simplify purification and separation. Such selectively soluble polymers
simplify catalyst, reagent, and product recovery and enable ...
Studies of the relationship of protein structure to regulation and catalysis in tyrosine hydroxylase
(Texas A&M University, 2007-09-17)
Tyrosine hydroxylase (TyrH) catalyzes the rate-limiting step in the synthesis of the catecholamine neurotransmitters dopamine, epinephrine, and norepinephrine. Phosphorylation of Ser40 of rat TyrH activates the enzyme by ...
Surface spectroscopic characterization of oxide thin films and bimetallic model catalysts
(2009-05-15)
Oxide thin films and bimetallic model catalysts have been studied using metastable
impact electron spectroscopy (MIES), ultraviolet photoelectron spectroscopy (UPS), low
energy ion scattering spectroscopy (LEISS), X – ray ...
Designing phase selective soluble polymers for applications in organic chemistry
(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 ...
Theoretical studies of transition metal surfaces as electrocatalysts for oxygen electroreduction
(Texas A&M University, 2007-09-17)
In the last few years the quest towards a hydrogen based economy has intensified
interest for effective and less expensive catalysts for fuel cell applications. Due to its
slow kinetics, alternative catalysts for the oxygen ...
N-heterocyclic carbene catalysis: expansion of
(2009-05-15)
Asymmetric hydrogenation as a general route to polypropionates has been
explored for allylic alcohols, acids, and derivatives, which has led to the generation of
2,4-dimethylated hexane derivatives. Quantitative yields in ...
Dendrimer-encapsulated metal nanoparticles: synthesis, characterization, and applications to catalysis
(Texas A&M University, 2004-09-30)
The research in this dissertation examines the chemistry and applications of dendrimers in homogeneous catalysis. We examined interactions between dendrimers and charged probe molecules, prepared dendrimer-encapsulated ...
Mechanisms of transition-metal catalyzed additions to olefins
(Texas A&M University, 2005-08-29)
Transition metal catalyzed reactions have an important place in synthetic chemistry, but the
mechanistic details for many of these reactions remain undetermined. Through a combination of
experimentally determined 13C kinetic ...
Supramolecules with dimolybdenum or chiral dirhodium units
(Texas A&M University, 2007-04-25)
This dissertation concerns the syntheses and characterization of supramolecules with quadruply bonded Mo2 4+ units, Mo2(DAniF)3
+ (DAniF = N,N'-di-p-anisylformamidinate) or cis-
Mo2(DAniF)2 2+, and chiral organometallic ...
