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),...
This research was performed to establish the feasibility of using Direct Metal Deposition (DMD) technology to deposit nickel powder to a nickel substrate. The substrate is electrodeposited pure nickel, and the material to be deposited is Metco...
Coal-fired power plants--Environmental aspects--United States; Mercury wastes--Environmental aspects--United States
This dissertation tests whether or not mercury emissions from electric power plants are not a significant contributor to mercury measurements in rainfall and argues that the current United States (U.S.) Environmental Protection Agency (EPA)...
This dissertation describes (1) size-dependent electrochemical oxidation/stripping of gold and silver nanoparticles (NPs), (2) alloying of copper with gold nanoparticles at underpotential deposition potentials, (3) electrochemical characterization...
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 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...

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...
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...
Heart--Hypertrophy; Hydrogen sulfide--Therapeutic use
Background: Although matrix metalloproteinase (MMPs) and tissue inhibitor of metalloproteinase (TIMPs) play a vital role in tumor angiogenesis and TIMP-3 causes apoptosis, their role in cardiac angiogenesis is unknown. Interestingly, a disruption...
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...
Understanding the nucleation and early stage growth of crystals from the vapor phase is important for realizing large-area single-crystal quality films, controlled synthesis of nanocrystals, and the possible discovery of new phases of materials....
Lead Zirconate Titanate (PZT), known for its ferroelectric properties, is widely used in micro-electromechanical (MEMS) and nano-electromechanical (NEMS) devices. PZT is a ceramic material that is most commonly found in its sol gel form, which...
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...
Freshwater zooplankton; Global warming; Nitrogen--Environmental aspects
Aquatic ecosystems face major transformations as humans increasingly alter their environment by introducing exotic species and changing the temperature regime and nutrient availability of freshwater systems. The impacts of such alterations of...
