Simultaneous impregnation and microencapsulation of CaCl using silica gel and methyl cellulose for thermal energy storage applications.

Thermal energy storage utilizing the adsorption of moisture from air is a promising energy storage technology due to its high energy density and minimum heat losses. Salt hydrates and salt hydrate composites, such as calcium chloride (CaCl) and CaCl-based composites, have shown favourable energy storage properties in this area of research. However, these materials have shown issues with stability due to swelling and deliquescence.

Triggered Nanoexplosions of Pd Hollow Spheres.

Gas filled Pd nanocontainers can serve as model nanochambers for reaction and phase equilibria studies. In the current study, palladium hollow spheres (PdHS) filled with oxygen are brought in intimate contact with hydrogen filled PdHS at room temperature (with internal pressure in both the spheres at 20 bar). The molecular hydrogen gets chemisorbed in the Pd shell and further diffuses into the oxygen filled sphere.
