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 authors have presented a literature review on computational and experimental studies on the thermal conductivity of nanostructure enhanced phase change materials (nePCMs). It was found that a wide range of nanostructures have been investigated, from carbon nanostructures and carbon nanotubes to metal and metal oxide nanoparticles. The carbon nanostructures and nanotubes were found to generally enhance the thermal conductivity of the PCMs by a greater amount than metal or ...
Octane solutions containing metal salts were irradiated with 350 nm photons using oleoyl sarcosine as a particle stabilizer and benzophenone as a particle sensitizer to produce suspensions of nanometer-sized metal particles. The goal of this study was to prepare nanofluids with enhanced thermal conductivity in comparison to pure octane. It was found that the thermal conductivities were enhanced by the production of the nanofluids, with a 10 % enhancement being observed at 50oC....
The effects of incorporating phase change materials (PCMs) into concrete on the potential service lives of bridges were investigated. It was determined that PCMs could potentially be used in the future to reduce the effects of freeze-thaw cycles on bridges, but more work needed to be done to improve the strength of concretes containing PCMs before this could be applied. It was determined that increasing the latent heat of fusion ...
