Elastocaloric, barocaloric and magnetocaloric effects in spin crossover polymer composite films [PDF]
Giant barocaloric effects were recently reported for spin-crossover materials. The volume change in these materials suggests that the transition can be influenced by uniaxial stress, and give rise to giant elastocaloric properties.

Barocaloric effect on graphene. [PDF]
AbstractWe describe how mechanical strain is able to control the flow of heat on a graphene sheet, since this material can either absorb or expel heat from/to a thermal reservoir, depending on the strain energy. In a similar fashion as the magneto- and electro-caloric effects, the present case considers the fact that a mechanical strain produces a ...

Giant barocaloric effects in formamidinium iodide [PDF]
Barocaloric effect is the thermal response of materials to the external pressures, which provides a promising alternative to the current vapor-compression refrigeration. The effect has been widely observed in a variety of materials. Here, we report giant

Thermal batteries based on inverse barocaloric effects. [PDF]
To harvest and reuse low-temperature waste heat, we propose and realize an emergent concept—barocaloric thermal batteries based on the large inverse barocaloric effect of ammonium thiocyanate (NH 4 SCN). Thermal charging is initialized upon pressurization through an order-to-disorder phase transition, and the ...

Giant barocaloric effect in commercial polyurethane
Barocaloric effect in polymers is barely recognized and limited to a few reports in the literature. This effect consists of a thermal response of the material when a hydrostatic pressure is applied, allowing its application in the field of solid-state ...

Ultrasensitive barocaloric material for room-temperature solid-state refrigeration [PDF]
A small driving pressure is desirable for practical application of barocaloric materials. Here, the authors demonstrate a sensitive barocaloric effect in NH4I due to strong reorientation-vibration coupling.

Low pressure reversibly driving colossal barocaloric effect in two-dimensional vdW alkylammonium halides [PDF]
Plastic 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.

All-temperature barocaloric effects at pressure-induced phase transitions [PDF]
Caloric 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 ‒
