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 ...
Fundamental Studies towards Transistion Metal Catalysis and Application of Chromium Salen Complexes for the Synthesis of Polymers
(2010-07-14)
?The body of this work spans both fundamental organometallic chemistry and the
application of previously studied catalyst systems to produce new polymeric materials.
The cone angle of triphenylphosphite was estimated ...
DEVELOPMENT AND MECHANISTIC STUDIES OF THE CHROMIUM TETRAMETHYLTETRAAZAANNULENE CATALYST SYSTEM FOR THE COPOLYMERIZATION OF CARBON DIOXIDE AND EPOXIDES
(2010-07-14)
A prominent goal of scientists is to develop products and processes to meet the
ever-growing needs of society. Today's needs include products that are economical,
specialized, and made through processes with minimal impact ...
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 ...
