Elastocaloric, barocaloric and magnetocaloric effects in spin crossover polymer composite films [PDF]

open access: yesNature Communications
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.

Colossal and reversible barocaloric effect in liquid-solid-transition materials n-alkanes [PDF]

open access: yesNature Communications, 2022
Barocaloric effect, previously reported in solid-solid phase transition materials, offers a green alternative to current cooling technology. Here the authors report colossal BCE in n-alkanes associated with liquid–solid transition.

Barocaloric effect on graphene. [PDF]

open access: yesSci Rep, 2017
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]

open access: yesAPL Materials, 2022
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]

open access: yesSci Adv, 2023
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

open access: yesPolymer Testing, 2021
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]

open access: yesNature Communications, 2022
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]

open access: yesNature Communications
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]

open access: yesNature Communications
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 ‒
