The research in this dissertation describes a simple electrochemical approach for fabricating nanoscale (metal/metal) or molecular (metal/polymer or self assembled monolayer (SAM)/metal) junctions. The fabrication involves metal deposition on one...
This thesis describes 1) the kinetics of vapor phase place exchange reactions on films of gold monolayer protected clusters (Au MPCs) to alter the functionality of the Au MPCs, 2) applications of the reaction for altering chemiresistive sensing...
Most of the structures in submillimeter-scale engineering are created from thin films, making them essentially two-dimensional (2D). Significant work has been done to fabricate 3D structures using self-folding, a deterministic form of...
A process for fabricating PMOS transistors and test devices has been developed for educational purposes as part of a microfabrication undergraduate/graduate laboratory course at the University of Louisville. This is to help students from multiple...
Protective coatings; Microelectromechanical systems
PARYLENE (poly-para-xylylene) is mostly used as a conformal protective polymer pin-hole free coating material to uniformly protect any component configuration on diverse substrates. This thesis describes in detail how the unique properties of...
Microhotplates for metal oxide gas sensors are fabricated using platinum microheaters and tested. Power consumption is monitored and temperature distributions are observed using infrared microscopy. Temperature line traces are extracted from the...
In this work, micro fabrication techniques are explored not only to simplify the production of complex lab on-a-chip devices (LOC), but also micro fabrication will be utilized to create intelligent design features that will enhance an...
The discovery of carbon nanotubes and subsequently graphene has led to an interest in carbon materials as sensing elements due to their unique properties. Graphene is a 2-dimensional material that has a large surface area that can be exposed to...
This dissertation demonstrates an elegant method, known as 'micro-origami' or strain architecture to design and fabricate three-dimensional MEMS structures which are assembled using actuation of a metal-oxide bilayer with conventional planar...
The purpose of this research is to understand how the process parameters surrounding the Direct Metal Deposition (DMD) process affect the properties of the deposition. The powder used in this research is pre-alloyed titanium powder (Ti-6Al-4V),...
No current microfabrication technique exists for producing room-temperature, high-precision, point-to-point polymer nanofibers in three dimensions. Producing rounded structures in a third dimension is particularly difficult to accomplish with...
Assessing the functionality of the endothelium can provide insight into the initiation and formation of arterial diseases. One of the most important functions of the endothelial layer is its permeability. The integrity of the cell monolayer and its...
Age-related macular degeneration (ARMD) and retinitis pigmentosa (RP) are the two leading causes of blindness in the world today. Despite enormous efforts and advances in clinical treatment of eye diseases, there is no established method or cure of...
Integrated circuits--Design and construction; Integrated circuits industry--Technological innovations
Lithographic processes for printing device structures on integrated circuits plays a major role in the semiconductor industry. This project aims at designing and fabricating a programmable mask for a direct write lithography system which can...
The Knudsen pump works on the principle of thermal transpiration. As a result of requiring a thermal gradient, channel hydraulic diameter smaller than the mean free path of the gas being pumped, and having no moving parts, the Knudsen pump features...
Understanding of the band structure of the new nano materials is essential to have a deeper insight into their optical and electrical properties. Along with the existing techniques used for characterization of nano-materials, it is also important...
Hematite synthesized by low pressure oxygen plasma has been shown previously to exhibit promising characteristics as a photo-anode for a photoelectrochemical water splitting cell. It is cheap, stable and has a 2.1 eV bandgap and exhibits a...
Fast food restaurants--Employees--Job satisfaction; Fast food restaurants--Employees--Social conditions; Fast food restaurants--Employees--Economic conditions; Labor turnover
This study (N = 935) examined the relationships of demographic characteristics, organizational justice (including the three areas: distributive, procedural, and interactional), and organizational socialization with the dependent variable of intent...
Energy independence requires that the nation reduce its dependence on foreign oil imports. This can be achieved through electrification of transportation vehicles if proper battery technology can be developed. In addition, the renewable energy...
