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

Nature 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 Barocaloric Effects at Triple‐Phase Points

ENERGY & ENVIRONMENTAL MATERIALS
Barocaloric effect underlies a promising emission‐free and highly efficient cooling technology. The current wisdom to design barocaloric materials is to find materials undergoing a temperature‐induced phase transition with huge latent heats and then to apply a pressure to harvest the heat.

Thermal batteries based on inverse barocaloric effects. [PDF]

Sci 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 ...

Inverse barocaloric effects in ferroelectric BaTiO3 ceramics [PDF]

APL Materials, 2016
We use calorimetry to identify pressure-driven isothermal entropy changes in ceramic samples of the prototypical ferroelectric BaTiO3. Near the structural phase transitions at ∼400 K (cubic-tetragonal) and ∼280 K (tetragonal-orthorhombic), the inverse ...

High-Efficiency Thermal Battery Regulated by Ultralow Magnetic Fields. [PDF]

Small Sci
A magneto‐responsive composite is reported that, for the first time, achieves a noncontact phase transition with an ultralow magnetic field (≈0.04 T). It exhibits a colossal entropy change of ≈507.6 J kg−1 K−1, an enthalpy of 181.1 J g−1, and a ≈47.6 K temperature rise, alongside enhanced thermal conductivity and heat‐release efficiency, making it ...

Barocaloric effect on graphene. [PDF]

Sci 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 ...

Colossal barocaloric effects in plastic crystals [PDF]

Nature, 2019
Solid-state refrigeration technology based on caloric effects are promising to replace the currently used vapor compression cycles. However, their application is restricted due to limited performances of caloric materials. Here, we have identified colossal barocaloric effects (CBCEs) in a class of disordered solids called plastic crystals. The obtained

Barocaloric thermal batteries

, 2021
Nowadays the world is facing a prominent paradox regarding thermal energy. The production of heat accounts for more than 50% of global final energy consumption while the waste heat potential analysis reveals that 72% of the global primary energy consumption is lost after conversion mainly in the form of heat.
