"Enhanced Water Adsorption Capacity in Fullerene-Pillared Porous Graphene"

Researchers from Chiba University in Japan have developed fullerene-pillared porous graphene (FPPG), a carbon composite with highly designable and controllable pore structures. FPPG with a 25 ± 8% fullerene filling ratio exhibited the largest water vapor adsorption capacity at 40% relative humidity, due to the production of large uniform nanopores. This novel material has potential applications in gas and liquid purification and concentration processes, which could significantly improve energy efficiency and reduce costs.

Subglacial Dehydration of Crystal Hydrate.

Researchers have discovered a porous organic crystal that can adsorb water into 1-nm-wide channels at more than 55% relative humidity, with the water uptake/release being chromogenic. The nanoconfined water is in a state of flux above −70 °C, thus allowing low-temperature dehydration to occur. This discovery unlocks opportunities for designing materials that capture/release water over a range of temperatures that extend well below the freezing point of bulk water.
