Breathing effect mof
WebAs the gas is liberated again, the MOF shrinks back to its original form and absorbs heat, which could be used to refrigerate its surroundings. This phenomenon, dubbed breathing-caloric effect, adds to a family of effects where external stimuli – such as mechanical forces and electromagnetic fields – induce cooling.
