Colossal barocaloric effects in plastic crystals [PDF]

open access: yesNature, 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

Large barocaloric effects in thermoelectric superionic materials [PDF]

open access: yesPhysical Review Materials, 2020
We predict the existence of large barocaloric effects above room temperature in the thermoelectric fast-ion conductor ${\mathrm{Cu}}_{2}\mathrm{Se}$ by using classical molecular dynamics simulations and first-principles computational methods. A hydrostatic pressure of 1 GPa induces large isothermal entropy changes of $|\mathrm{\ensuremath{\Delta}}S ...

Giant barocaloric effect in neopentylglycol-graphene nanosheets composites with large thermal conductivity

open access: yesMaterials Research Letters, 2022
We report the enhancement of the thermal conductivity of neopentylglycol (NPG) by compositing it with graphene nanosheets (GPNs). Adding 50 wt% GPNs enhanced the thermal conductivity from 0.42 to 18.4 Wm−1K−1, and the barocaloric entropy change can still

Electrocaloric and barocaloric effects in CsH2PO4 ferroelectric

open access: yesCondensed Matter Physics, 2022
To investigate the caloric effects in the CsH2PO4 ferroelectric, a modified pseudospin model of this crystal is used, which takes into account the dependence of the parameters of interaction between pseudospins on lattice strains. The model also takes into account the dependence of the effective dipole moment of a pseudospin on the order parameter.

Elucidation of barocaloric effect in spin crossover compounds

open access: yesActa Crystallographica Section A Foundations and Advances, 2022
The search for new efficient materials and refrigeration mechanisms is a key challenge toreplace the conventional vapor compression technology. An attractive alternative technologyuses the caloric refrigeration cycle, which is based on the adiabatic temperature and isothermalentropy change upon tuning an external parameter such as pressure, electric ...

Martensitic Transformation and Barocaloric Effect in Co-V-Ga-Fe Paramagnetic Heusler Alloy

open access: yesMetals, 2022
In the present study, polycrystalline Co50V34Ga16−xFex (1≤x≤2) quaternary Heusler alloys were fabricated by the arc-melting method. It was found that they undergo a paramagnetic martensitic transformation (MT) from the L21-type cubic austenitic structure

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

open access: yesAdv 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 ...

Tunable barocaloric effects of two-dimensional hybrid perovskite through carbon chain lengths [PDF]

open access: yesAPL Materials
Organic–inorganic hybrid perovskites have recently emerged as a promising class of barocaloric materials. The entropy change in such materials mainly originates from the order-to-disorder phase transition of the organic carbon chains.

Solid-State Heating Using the Multicaloric Effect in Multiferroics

open access: yesMagnetochemistry, 2021
The multicaloric effect is defined as the adiabatic reversible temperature change in multiferroic materials induced by the application of an external electric or magnetic field, and it was first theoretically proposed in 2012. The multicaloric effects in
