Heterogeneous Catalysis by Gold: The Effect of Oxide Support, External Conditions, and the Metal/Oxide Interface.
(2009)
Bulk Au is inert. However, when dispersed as small particles on an oxide support its chemistry changes dramatically, and can become active in many catalytic reactions. This unprecedented change in Au chemistry is still not ...
Hydrogen Spillover and Adsorption on Nanoporous Carbon-Based Materials for Storage Applications.
(2009)
Interest in hydrogen as an alternative fuel has grown recently due, in part, to increasing global energy demands and environmental concerns. A challenge for commercialization of hydrogen fuel cells is storage of an adequate ...
Bimetallic Silver Catalysts for the Reformate-Assisted Selective Catalytic Reduction of NOx.
(2011)
The objective in this dissertation was to investigate a strategy to improve the low- temperature performance of Ag/Al2O3 for hydrocarbon selective catalytic reduction
of NOx. Two approaches were studied. The first approach ...
Surface Characterization of Oxides Synthesized by Successive Ionic Layer Deposition.
(2010)
Successive ionic layer deposition (SILD) is an aqueous technique for depositing thin oxide films on a surface in a layer-by-layer fashion through a series of chemical reactions. This dissertation examines empirical aspects ...
Brownian Dynamics Simulation of Dilute Polymer Chains.
(2008)
Local motion of polymers is extremely important while studying the behavior of single strand DNA in DNA unzipping and replication, understanding rheological properties of polymers in confined in narrow gaps for head-disk ...
Nanostructured Electrocatalysts for Triglyceride Hydrogenation.
(2011)
An electrochemical process for the reduction of organic compounds could have a
number of advantages over thermochemical reduction, including enhanced separation
between reactants and products, lower operating temperatures ...
Dendron Avidity Platforms with Orthogonal Focal Point Coupling Site.
(2010)
This thesis explores the design and synthesis of bifunctional or modular platforms from poly(amidoamine) (PAMAM) dendrons. PAMAM dendrons with an orthogonal focal point are evaluated, testing several click chemistry ...
Universal Scaling of Linear and Nonlinear Rheological Properties of Semidilute and Concentrated Polymer Solutions.
(2008)
This dissertation examines the universal rheological behavior of linear polymers in solution. The universality of the dependence of zero-shear viscosity on concentration for both flexible and semiflexible polymers in good ...
Carbide and Nitride Based Catalysts for Synthesis Gas Conversion.
(2011)
The production of fuels and chemicals from syngas (H2 and CO) plays a critical role in our economy and will play an even greater role in the future as we transition from petroleum-derived products to biomass-derived products. ...
Microdroplet-Enabled Co-Cultivation and Characterization of Microbial Communities.
(2012)
The majority of existing microbial species, in particular bacteria living in synergistic
communities, have not been cultured in the laboratory. One important reason
behind this unculturability" is that conventional laboratory ...
