Superprism phenomenon in photonic crystals: Guiding the path of light
Photonic crystals can be thought of as 'optical analogues' to electronic semiconductors, and have been widely studied for their periodically-varying indexes of refraction. This allows for controlling the propagation of ...
Regular Arrays of QDs by Solution Processing
Hydrophilic silicon and germanium quantum dots were synthesized by a "bottom-up" method utilizing micelles to control particle size. Liquid phase deposition of silica on these quantum dots was successful with and without ...
Investigating mechanical and physical properties of nanostructures
In the first part of the dissertation, mechanical properties of bundles of carbon nanotubes are investigated. Earlier experiments showed that these tubes are tightly packed in the bundles, proving that they are strongly ...
Reshaping the metallic surface of a gold nanoshell
Two methods for the controlled reshaping of metal nanoparticles have been investigated: pulsed laser induced reshaping and surfactant-mediated restructuring. The laser induced shape changes of gold nanoshells have been ...
Nanoparticle assemblies and interactions
Silica nanoparticles coated with functionalized organosilane molecules are used as substrates for the formation of assemblies of gold nanoparticles. In an assembly of nanoparticles, the optical response of each nanoparticle ...
Thermophysical property measurements at high temperatures for liquid metal alloys and gadolinium oxide-doped uranium dioxide samples
New techniques for obtaining various thermophysical properties, i.e., densities and incremental enthalpies of selected materials at high temperatures have been developed with emphasis on the utilization of levitation ...
