Molten selenium, silver, cadmium, and tin were used to prepare a-Se, and a-Se98M2 (M = Ag, Cd, and Sn) alloys in order to determine the thermo-physical properties of these materials using the transient plane source technique. In order for these alloys to be used in industrial applications such as phase change optical storage, photo electrochemical solar cells, and holographic recording systems, among others, their thermal transport properties needed to be ...

Disodium hydrogenphosphate dodecahydrate was investigated for its thermophysical properties and the effects that temperature had on these properties. The goal of this work was to determine if this material was a suitable phase change material for use in supercooled thermal energy storage. It was found that this hydrate could efficiently exchange energy between itself and heat sources, it could reduce heat loss from energy storage systems, and it could store ...

The transient plane source technique was used to simultaneously measure the thermal conductivity, thermal diffusivity, and specific heat of a concrete sample to determine how these properties change when exposed to high temperature. The sample was heated and the properties were measured at 20, 90, 110, 200, 500, and 600oC. At this point, the sample was allowed to cool, and measurements were once again taken at 500, 200, and 20 oC. It was found that after exposure to ...

The thermal transport properties of Ti1.1CrMn powder were determined. This metal hydride shows promise for use in hydrogen storage applications due to its excellent cold-start properties. The thermal conductivity, thermal diffusivity, and specific heat of oxidized and activated powder samples of this metal hydride were determined using the transient plane source technique in a high pressure vessel. It was found that the effective thermal conductivity of the samples showed ...

The thermal properties of synthetic gas hydrate-bearing sediment samples were determined by the transient plane source method. The samples were made up of sand, water, gas, and methane hydrates, and these samples were supercooled to minimize the effects of the heat of fusion of methane hydrate on the thermal conductivity measurements. The thermal conductivity was found to increase with increasing methane hydrate saturation for saturations from 0-0.3. Thermophysical models were ...
