Hydrogen gas has been successfully produced from sewage sludge by supercritical water gasification. Therefore, whether toxic compounds are synthesized in the supercritical water gasification of sewage sludge should be clarified because of the complex pollutants in sludge. In the current study,...

The utilization of paraffin in the latent thermal energy storage (LTES) system for solar energy storage is hampered by its low thermal conductivity. Paraffin/nickel foam and paraffin/copper foam composite phase change materials (PCMs) were prepared using a vacuum impregnation method in the...

Eutectic molten salt can be used as the latent thermal energy storage (LTES) medium in solar energy applications. In the present study, eutectic salt (50wt% NaNO3, 50wt% KNO3) with a melting temperature of about 220°C was employed as the PCM for the middle-temperature solar energy application,...
