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 ...
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 ...
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 ...
