(2011-08-08)A superconducting microwave cavity has been designed to test advanced materials for use in the accelerating structures contained within linear colliders. The electromagnetic design of this cavity produces surface magnetic ...
-
(2009-06-02)The chemisorption and electrochemical hydrogenation of hydroquinone (H2Q) at polycrystalline (pc) Pd, well-ordered Pd(100), and Pd-modified Au(hkl) electrodes were studied using a combination of ultra-high vacuum (UHV) ...
-
(2016-10-14)Layer-by-layer deposition has provided a framework in which coatings with a variety of functionality can be deposited from aqueous solutions in ambient conditions. Despite the many advantages of layer-by-layer assembly, ...
-
(2016-12-15)Scratch behavior on polymeric films was investigated. The effect of film orientation and architecture on scratch resistance was determined. Film orientation was obtained by uniaxial stretching and its architecture was ...

Improvement in the Mechanical Properties of B-Staged Carbon Nanotube/Epoxy Based Thin Film Systems (2011-01-11)Polymeric systems have been the subject of tremendous interest to the aerospace industry due to their high strength per weight ratio but have not seen the use projected due to their poor compression after impact strength, ...
-
(2012-07-16)A pair of studies investigating the deposition and surface chemical properties of ultrathin metal films were pursued: (i) Pt-Co alloys on Mo(110); and (ii) Pd on Pt(111). Experimental measurement was based on a combination ...
-
(2022-06-03)MXenes are a class of two-dimensional nanomaterials which have drawn interest in a wide variety of fields (e.g., energy storage, sensing, catalysis, separation, etc.). While there are hundreds of possible MXene compositions, ...
-
(2012-07-16)Thin layers with high barrier to oxygen and other gases are a key component to many packaging applications, such as flexible electronics, food, and pharmaceuticals. Vapor deposited thin films provide significant gas barrier, ...
-
(2018-05-04)This thesis presents three investigations into the responsive physical and thermal properties of polyelectrolyte layer-by-layer assemblies. The first study focuses on hydrogen bonded, layer-by-layer assembled films and ...
-
(2016-11-08)For hydrogenated amorphous silicon (a-Si:H) thin film PIN diodes fabricated using plasma-enhanced chemical vapor deposition, the effects of the n^+ layer deposition power, the existence of an aluminum reflector layer, and ...
-
(2011-05-05)Two-phase (La0.7Sr0.3MnO3)0.5:(CeO2)0.5 (LSMO:CeO2) heteroepitaxial nanocomposite films were grown on SrTiO3 (STO) (001) by pulsed laser deposition. XRD and TEM results show that LSMO:CeO2 films epitaxially grow on STO as ...
-
(2011-08-08)The thermal conductivity of PMMA films with thicknesses from 5 to 50 nanometers and layered over a treated silicon substrate is explored numerically by the application of the reverse non-equilibrium molecular dynamics ...
-
(2017-08-01)The present work is dedicated to addressing nanotribological issues of ultra-thin (sub-10 nm) films at contacting interfaces. In devices such as micro-electro-mechanical systems (MEMS), thin films are deposited for specific ...
-
(2023-07-10)Reactive intermediates invoked in the functionalization of strong C-H bonds are difficult to characterize. The high energy required to break C-H bonds often means the lifetime of the intermediates is fleeting due to ...
-
(2014-05-07)The PECVD intrinsic, n^(+), and p^(+) a-Si:H thin film deposition processes have been studied by the optical emission spectroscope to monitor the plasma phase chemistry. Process parameters, such as the plasma power, ...
-
(Texas A&M University, 2005-11-01)This dissertation is focused on understanding heterogeneous metal catalysts supported on oxides using a model catalyst system of SiO2 thin film supported metal nano-clusters. The primary technique applied to this study is ...
-
(2014-08-13)Magnetic shape memory alloys are a class of shape memory alloys, and therefore exhibit a thermoelastic martensite phase transformation between symmetric and asymmetric crystalline states induced by appropriate temperature ...
-
(2012-07-16)Transparent electrodes made from metal oxides suffer from poor flexibility and durability. Highly transparent and electrically conductive thin films based on carbon nanotubes (CNTs) were assembled as a potential indium tin ...
