Intergranular Water and Permeability of the Lake Vostok Accretion Ice, Eastern Antarctica: Author: Jepsen, Steven Michael; Date: 2005-12-15; Program: Engineering; Abstract: The relative importance of nonhydrostatic stress and lattice-rejected impurities on the phase equilibrium of intergranular liquid water in the Vostok accretion ice, Eastern Antarctica, was examined in this study. In addition, experiments were conducted to examine the influence of intergranular water in ice on the permeability of a Light Non-Aqueous Phase Liquid (LNAPL) hydrocarbon. Sub-grain scale stresses in the Vostok accretion ice were simulated with anisotropic elastic and elastocreep finite element (FE) models and compared to X-ray dislocation topographs. The phase equilibrium conditions ...; Download File | View full details

Size Dependence of the Magnetic Properties of Cobalt Oxide Nanoparticles Mineralized in Protein Cages: Author: Resnick, Damon Aaron; Date: 2005-12-15; Program: Physics; Abstract: A major question in the physics of magnetic nanoparticles is how the size affects the magnetic properties in magnetic nanoparticle systems. In particular, the magnetic properties can be affected by finite-size effects or surface effects. It is this author's belief that surface effects and not finite-size effects play the dominate role. This study is a specific example of how to try to answer this question by looking at different sizes of Co₃O₄ nanoparticles. In order to answer this question as well as better understand this system, different antiferromagnetic Co₃Oâ...; Download File | View full details
