Thermal Stability of Supported Gold Nanoparticles
(2011)
Nanoparticle gold is of interest for a wide array of applications including catalysis, gas sensing, and light absorption for color filters and optical switches. Many of these applications are dependent upon the particles ...
SIMULATION STUDIES AND FABRICATION OF MICROTRAPS WITH LONG ASPECT RATIO TO STORE HIGH DENSITY OF POSITRONS
(2015)
Conventionally, non-neutral antimatter is stored using a Penning-Malmberg trap, a single tube with aspect ratios being of the order of less than 10:1. Parallel microtubes with aspect ratios of 1000:1 have the potential to ...
Electrical and Optoelectronic Properties of Two-Dimensional Materials
(2016)
Electrical and optoelectronic properties of bulk semiconductor materials have been extensively explored in last century. However, when reduced to one-dimensional and two-dimensional, many semiconductors start to show unique ...
Persistant Photoconductivity of Strontium Titanate
(2016)
Strontium titanate (SrTiO$_3$) is a transparent conducting oxide with a range of interesting properties, including a large, temperature-dependent dielectric constant and superconductivity at low temperatures. It has a wide ...
Pressure-Induced Phase Transitions of Indium Selenide
(2016)
In2Se3 has potential as a phase-change material for memory applications. Understand- ing its phase diagram is important to achieve controlled switching between phases. Pressure-dependent phase transitions of In2Se3 bulk ...
EFFECT OF SILICON, TANTALUM AND TUNGSTEN DOPING AND POLARIZATION ON BIOACTIVITY OF HYDROXYAPATITE
(2012)
Hydroxyapatite (HAp) ceramics has important applications as bone graft because of the structural and compositional similarities with bone tissue. However, inferior osteogenic capacity to bone and poor mechanical properties ...
ENABLING HIGH SPEED FRICTION STIR WELDING OF ALUMINUM TAILOR WELDED BLANKS
(2015)
Current welding technologies for production of aluminum tailor-welded blanks (TWBs) are utilized in low-volume and niche applications, and have yet to be scaled for the high-volume vehicle market. This study targeted further ...
Compliant Material for MEMS Contacts and Interconnects
(2012)
This dissertation focuses on deformation in metallic materials which are possible choices for flexible electrical contacts. A contact for a micro mechanical switch has been fabricated using electroplated gallium (Ga) on ...
SPECTROELECTROCHEMICAL PHOTOLUMINESCENCE SPECTROSCOPY AND IMAGING OF REACTIVE SURFACE DEFECTS IN TITANIUM DIOXIDE NANOPARTICLES
(2016)
Titanium dioxide (TiO2) nanoparticles have shown promise as a low-cost and effective material for a wide range of applications including batteries, photovoltaics, and photocatalysis. To optimize TiO2 nanoparticles in these ...
