All-temperature barocaloric effects at pressure-induced phase transitions [PDF]
Nature CommunicationsCaloric effects, which underpin one solution to solid-state refrigeration technologies, usually occur in the vicinity of solid-state phase transitions with a limited refrigeration temperature span. Here, we introduce and realize an unprecedented concept ‒

Low pressure reversibly driving colossal barocaloric effect in two-dimensional vdW alkylammonium halides [PDF]
Nature CommunicationsPlastic crystals as barocaloric materials exhibit the large entropy change rivalling freon, however, the limited pressure-sensitivity and large hysteresis of phase transition hinder the colossal barocaloric effect accomplished reversibly at low pressure.
