Atomic Jump Frequencies in Intermetallic Compounds Studied Using Perturbed Angular Correlation of Gamma Rays
Atomic jump frequencies were determined in a variety of intermetallic compounds through analysis of nuclear relaxation of spectra measured using the nuclear hyperfine technique, perturbed angular correlation (PAC) of gamma ...
EXCIMER LASER INTERACTION WITH ZINC OXIDE
When single crystal ZnO is exposed to 193-nm laser photons in vacuum at fluences below 100 mJ/cm
Experimental investigations of a proposed chromophore correlation model of self healing of Disperse Orange 11 doped in Poly (methyl methacrylate)
We studied photodegradation and recovery of amplified spontaneous emission (ASE) in Disperse Orange 11 dye doped in Poly(methyl methacrylate)(PMMA) as a function of dye concentration and sample temperature. A simple ...
Localized Chemistry of 99Tc in Simulated Low Activity Waste Glass
A priority of the United States Department of Energy (DOE) is to dispose of the nuclear waste accumulated in the underground tanks at the Hanford Nuclear Reservation in Richland, WA. Incorporation and stabilization of ...
Spectroscopic and Microscopic Investigations of Phthalocyanine Aggregates on Au(111)
Self-assembled organic π systems are of interest because of their potential applications in light harvesting and electron transfer. Phthalocyanines (Pc) demonstrate desirable photonic and electronic properties, thus making ...
ATOMISTIC SIMULATION STUDY OF THE EFFECTS OF POINT DEFECTS ON THE INCEPTION OF PLASTIC DEFORMATION IN METALS
Atomistic simulations have been used to study the effect of various types of point defects on the mechanical response of FCC single crystals in nanoindentation and uniaxial tests. To study the effect of spatial distribution ...
FABRICATION AND CHARACTERIZATION OF MULTIFUNCTIONAL POLYETHERIMIDE/CARBON NANOFILLER COMPOSITES
Polyetherimide (PEI) is a high-performance thermoplastic, showing great potential in many important applications including airplanes and electronics, due to its excellent mechanical and thermal properties. At the same time, ...
POLY(3-HYDROXYBUTYRATE-CO-3-HYDROXYVALERATE) - CELLULOSE NANOWHISKERS COMPOSITES BY SOLUTION CASTING
In this research, renewable biobased nanocomposites based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and cellulose nanowhiskers were prepared by solution casting. Nanocomposite structure and property investigations ...
Hydrogen and related defects in oxide semiconductors
Oxide semiconductors are an interesting class of materials which occur in a variety of crystal structures and exhibit diverse electronic and optical properties. This thesis is primarily focused on investigating defects in ...
MULTISCALE MODELLING AND SIMULATION OF DEFORMATION AND STRENGTH OF NANOSCALE METALLIC MULTILAYER SYSTEMS
The objective of this research is to investigate the deformation behaviors of two types of NMMs at lower length scales: 1) One dimensional Cu-Ni, Au-Ni nanowires with coherent interfaces and 2) Two dimensional Cu-Nb ...
