In adsorption cooling systems, molecules of vapor refrigerant (the guest) are adsorbed in the nanopores of a solid material (the host). Motkuri and his collaborators have studied how changing the geometry of the nanopores (pore engineering) and the speed of host-guest chemical interactions affect the cooling capacity and energy efficiency of adsorption cooling systems.
