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 ...

Understanding colossal barocaloric effects in plastic crystals. [PDF]

open access: yesNat Commun, 2020
AbstractPlastic crystal neopentylglycol (NPG) exhibits colossal barocaloric effects (BCEs) with record-high entropy changes, offering exciting prospects for the field of solid-state cooling through the application of moderate pressures. Here, we show that the intermolecular hydrogen bond plays a key role in the orientational order of NPG molecules ...

Barocaloric Properties of Thermoplastic Elastomers

open access: yesFrontiers in Energy Research, 2022
Solid-state refrigeration represents a promising alternative to vapor compression refrigeration systems which are inefficient, unreliable, and have a high global warming potential. However, several solid-state cooling technologies—including those relying

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 ...
