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

Nat Commun
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.

Giant barocaloric effect in commercial polyurethane

Polymer 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 ...

Giant barocaloric effects in formamidinium iodide [PDF]

APL 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

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 ...

Impact of Controlled Magneto-Structural Coupling in MnCoGe-Based Compounds on the Design of Multifunctional Materials for Technological Advances. [PDF]

Adv Sci (Weinh)
In this work, the authors systematically investigate how Ni substitution regulates the magneto‐structural coupling and their functional consequences in the MnCoGe‐based compounds. Geometric nonlinear theory analysis reveals that Ni modification change of magneto‐structural transition can alleviate the lattice incompatibility, thereby broadening the ...

Colossal Barocaloric Effects at Triple‐Phase Points

ENERGY &ENVIRONMENTAL MATERIALS, Volume 8, Issue 5, September 2025.
Colossal barocaloric effects were achieved in odd‐numbered normal alkane systems, such as C17H36, C19H40 and C21H44 approaching triple‐phase point by overlapping two separated phase transitions of ordered‐disordered solid phase transition and solid–liquid phase transition under a relative low pressure.

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 ...
