Abstract We utilized nanoporous mayenite (12CaO·7Al2O3), a cost-effective material, in the hydride state (H−) to explore the possibility of its use for hydrogen storage and transportation. Hydrogen desorption occurs by a simple reaction of mayenit

The mole fraction distributions of CaO and SiO2 under a temperature gradient in a CaSiO3 melt were calculated by molecular dynamics. The temperatures at the cold and hot ends of the gradient were 1800 and 2200 K, respectively, in the simulation. We u
