Abstract: An energy storage system is provided. The energy storage system includes a vessel made of a refractory material and containing a phase change material, a thermally insulating cover at least partially surrounding the vessel, an emitter, made of a refractory material, having a first side arranged to be heated by the phase change material and a second side intended to radiate thermal power, at least one photovoltaic cell arranged to receive the thermal power emitted by the second side of the emitter, and electric means for heating the phase change material.

Abstract: The present invention relates to an amine grafted chitosan nanofiber having the formula (I) wherein R1 to R5 are independently selected from linear or branched C1-C20 alkandiyl C6-C24 arenediyl; k and m are independently selected from 1 to 10, wherein, in case that k and/or m are >1, each R4 and R5 group can be independently selected; and l and n are independently selected from 50-3000, a method for the preparation thereof and its use in heavy metal adsorption.

Abstract: A photocatalyst is provided that comprises activated carbon produced from date pits, impregnated with TiO2. The activated carbon can have a porous surface that can attract and trap pollutants flowing in air or water. The photocatalyst can be made by a method that includes preparing activated carbon by calcining date pits to form a precursor material, and then impregnating the precursor material with titanium dioxide.

Abstract: A method is provided for adsorbing organic molecules, pollutants, or both, by contacting the organic molecules, pollutants, or both, with a photocatalyst. The photocatalyst can be made by a method that includes preparing activated carbon by calcining date pits to form a precursor material, and then impregnating the precursor material with titanium dioxide.
