Synthesis, characterization and magnetic property studies of copper-based phosphate and silicate compounds containing nanosize transition metal oxide frameworks
The search for novel compounds with nanosize transition metal oxide frameworks is important for the study and understanding of materials with interesting and important magnetic and electronic properties. These low-dimensional ...
A theoretical study of the effects of an external electric field on adsorbate-surface systems
We have used the density functional ab initio method to conduct investigations on the effects of an applied electric field on the chemisorption bonds of adsorbate-surface systems, and on the reactivity of a gas phase ...
Magnetic and chemical effects in x-ray resonant exchange scattering in rare earths and transition metal compounds
The increased availability of synchrotron x-ray sources has facilitated the development of new diffraction techniques based on x-ray resonant exchange scattering (XRES). Resonant electric dipole (E1) and quadrupole (E2) ...
Band evolution and shell structure in large clusters: Aluminum(3-60)anion, copper(1-1113)anion, silver(1-58)anion, and gold(1-223)anion
Photoelectron spectroscopy of negatively, charged clusters of aluminum, copper, silver, and gold reveals electronic shell structure and electron energy band development. Photodetachment experiments on Au$\sb6\sp-$ also ...
Bose-Einstein condensation of lithium
Bose-Einstein condensation (BEC) in ultra-cold magnetically-trapped $\sp7$Li vapor was experimentally observed and quantitative measurements of condensate number were made. Compared to other BEC experiments, lithium is ...
Adiabatic thermal changes in dielectrics at low temperatures
The problem set up as the objective of the present thesis is the detection and measurement of adiabatic thermal changes in barium titanate ceramic at low temperatures. Concurrent with this is the problem of devising ...
The cooling of a surface, due to photoelectric emission
The cooling of a surface when thermionic electrons are emitted has been measured by Richardson and others. The results obtained for tungsten and other metals are consistent with recent determinations of the work functions ...

Scattering of antiplane surface waves by an embedded crack in a layered elastic solid
The scattering of an incident antiplane surface wave (Love-wave) by an embedded crack normal to the free surface in a layered half-space is investigated in this study. The crack is first assumed to be entirely contained ...
