Abstract:
Particles comprising a core and a shell at least partially surrounding the core, wherein the core comprises a transition metal dichalcogenide and the shell comprises a transition metal oxide are disclosed. The particles can possess enhanced absorption of light in the visible and UVB/UVA spectrum, without inhibiting their inherent oxidative properties significantly. The particles inserted into a SODIS platform can possess equal or greater photocatalytic properties compared to the current TiO2 SODIS method.

Abstract:
Storage systems based on latent heat storage have high-energy storage density, which reduces the footprint of the system and the cost. However, phase change materials (PCMs), such as NaNO3, NaCl, KNO3, have very low thermal conductivities. To enhave the storage of PCMs, macroencapsulation of PCMs was performed using a metal oxide, such as SiO2 or a graphene-SiO2, over polyimide-coated or nickel-embedded, polyimide-coated pellets The macro encapsulation provides a self-supporting structure, enhances the heat transfer rate, and provides a cost effective and reliable solution for thermal energy storage for use in solar thermal power plants. NaNO3 was selected for thermal storage in a temperature range of 300° C. to 500° C. The PCM was encapsulated in a metal oxide cell using self-assembly reactions, hydrolysis, and simultaneous chemical oxidation at various temperatures.
Abstract:
In one embodiment, a method for forming a conducting film includes depositing a base layer of a conducting polymer on a substrate, the polymer forming only a weak bond with the substrate, depositing a top layer of a conducting material on the base layer, applying adhesive tape to the top layer, and peeling the tape off of the substrate, removing the top layer along with the tape.
