Barocaloric effect of elastomers and plastic crystals: an outlook

, 2022
The urge for efficient and environmentally friendly alternatives for the current gas-based refrigeration is becoming more critical due to global warming and overpopulation. Among the main candidates, solid-state-based cooling technology is appealing to substitute the conventional systems. Recently, attention has been turned to the barocaloric effect in

Barocaloric effects in ferroelectrics

, 2017
Giant barocaloric effects driven by hydrostatic pressure have been suggested for cooling applications, but they have been traditionally seen only in a small range of magnetic materials that are relatively expensive. Here it will presented the pressure-dependent calorimetry data to demonstrate giant barocaloric effects in ferroelectric materials that ...

Exploring the expansion of the universe using the Grüneisen parameter

Results in Physics
For a perfect fluid, pressure p and energy density ρ are related via the equation of state (EOS) ω=p/ρ, where ω is the EOS parameter, being its interpretation usually constrained to a numerical value for each universe era.

Giant barocaloric effects in sodium hexafluorophosphate and hexafluoroarsenate

Journal of Applied Physics
Solid-state refrigeration using barocaloric materials is environmentally friendly and highly efficient, making it a subject of global interest over the past decade. Here, we report giant barocaloric effects in sodium hexafluorophosphate (NaPF6) and sodium hexafluoroarsenate (NaAsF6) that both undergo a cubic-to-rhombohedral phase transition near room ...

Barocaloric effect in a Gay-Berne liquid crystal

Physical Review E
A coarse-grained molecular Monte Carlo simulation of the barocaloric effect in a model Gay-Berne liquid crystal is presented, following the so-called indirect approach wherein the caloric response is obtained from thermodynamic arguments applied to the simulated equilibrium relation between pressure, density, and temperature.
