This proposal aims to investigate and compare the dynamics of CO2 when confined in a nanoporous Vycor (SiO2) matrix. The field of fluids in confined geometries is currently of... -
The dynamics of the calcium-ammonia-graphite decomposition with hydrogen
Graphite intercalation compounds (GICs) have potential as hydrogen storage materials, from direct physisorption of H2 or as a high surface area nanostructured host for metal... -
Phonon Density of States in Nanocrystalline YAG:Cr
Here we propose to measure the phonon density of states in nanocrystalline samples of YAG:Cr. Our parallel luminscence measurements have revealed dramatic changes in the phonon... -
Phonon confinement effects in Si-nanowires
Nanowires can be used for devices based on thermoelectrics and to convert the heat into electrical current. The material design challenge here is to create the materials where... -
