This thesis proposes a new Maximum Power Point Tracking (MPPT) algorithm employed in Wind Energy Conversion Systems (WECS). One of the major issues discussed in the literature concerning HCS is its inefficiency in detecting the peak power when...
III-nitrides (InN, GaN, AlN) are some of the most promising materials for making blue light emitting diodes (LED), blue laser diodes (LD) and high power, high temperature field effect transistors (FET). Current techniques produce GaN films with...
Microfabricated planar solar cells with an active solar collection area of 0.04cm2 were fabricated on n-type silicon wafers to test the viability of sputtered amorphous thin film photovoltaics for potential use in amorphous multijunction cells or...
More than 50% of the total energy produced is typically rejected in the form of waste heat from various processes. The grand challenge is that most of this waste heat is released at temperatures much lower than 1000 C, which makes it difficult to...
Electroactive polymers (EAPs), including conducting polymers (CPs) such as polyaniline (PAn), and hydrogels are exciting areas of research in disciplines such as biomedical engineering, with the goal of creating low-cost, lightweight, non-toxic...

This dissertation describes new procedures for synthesizing and purifying Au and Au/Ag nanoplates directly on surfaces as well as controlled binding of proteins to their surface. It also describes fundamental changes in the optical properties of Au...
In this dissertation, standardized methods for measuring electron emission (EE) from nanostructured materials are established. Design of an emitter array platform, synthesis and nanomanipulation of different types of are successfully conducted....
Draw A Secret password systems have recently come into vogue, primarily in the role of protecting a user’s cellular smart phone from external infiltration in lieu of a password. However, these password systems are only enabled for single touch...
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...
In the electronic and microfabrication industry, die separation is one of the most critical steps in producing an undamaged, stand-alone micro-scale device. For silicon based devices, it is the predominant step governing resistance to die failure...

Hydrophilic and conductive characteristics in polymers are mutually exclusive of each other. Hydrophilic polymer properties allow absorption of water up to several magnitudes above their dry weight. However, due to their molecular structure, they...
In this thesis self-assembled growth of Ag2Ga nano-needles on batch fabricated
micro-grippers are reported. The room temperature growth of Ag2Ga nano-needles have
been recently developed as stylus for Atomic Force Microscopy (AFM). Integration...
Background: Light cured composite resin can be time consuming for bonding orthodontic brackets. A new Blue light diode laser may reduce curing times for composite resins. Hypothesis: The laser will achieve similar bond strengths in half the time...
Nanomaterials have many intriguing applications in biology and medicine. Unique properties such as enhanced electrical properties, increased chemical reactivity and resistance to degradation, novel optical properties and comparable size to that of...
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...
Iron oxide, Fe2O3, is a promising material for water splitting reaction using solar
energy due to its stability and optimal bandgap of 2 eV. Even the recent efforts, however,
using Fe2O3 thin film materials reported low efficiencies due to poor...
