Reactivity of Oxide Surfaces and Metal-Oxide Interfaces: Effects of Water Vapor Pressure on Ultrathin Aluminum Oxide Films, and Studies of Platinum Growth Modes on Ultrathin Oxide Films and Their Effects on Adhesion
… (>10-9 Torr) and (2) characterization of Pt growth modes on ultrathin Ta silicate and silicon dioxide films and the effects of growth modes on adhesion of a Cu overlayer. These studies were conducted with X-ray photoelectron spectroscopy (XPS). Ni3Al(110) was oxidized (10-6 Torr O2, 800K) …

Electromechanical response of textured ferroelectric PZT thin film stacks
… layers serve as seeding (TiO2), buffer (SiO2), and conducting (Pt) layers with substantial thickness and stiffness compared to the main PZT layer. As a result, quantitative understanding of the mechanical behavior of each layer is required in order to extract the electromechanical …

Developing an energy efficient steam reforming process to produce hydrogen from sulfur-containing fuels
… sulfur-containing transportation fuel. A Rh-Pt/SiO2-ZrO2 catalyst has demonstrated good activity for the E85 steam reforming reaction. An industrial steam reforming process is often run less efficiently, with more water and at higher temperatures, in order to prevent catalyst deactivation. …

Role of adsorption in catalysis: applications of NMR relaxometry
… in this thesis focuses on the effects that adsorption processes on catalytic surfaces pose in controlling key steps that can affect and control reaction pathways. To that, the development of Nuclear Magnetic Resonance (NMR) relaxometry methods and the comparison with traditional catalytic was …
