Investigation of thermophysical properties of ternary nitrate based phase change material induced with mxene as novel class of nanocomposites

Concentrated Solar Power (CSP) technology has been identified as an alternate renewable and clean energy source. Thermal energy storage (TES) system which is vastly used in this technology requires good thermophysical properties for an optimum usage of the technology. Molten salt, an inorganic salt...
