Colossal Reversible Barocaloric Effects in a Plastic Crystal Mediated by Lattice Vibrations and Ion Diffusion

open access: yesAdvanced Science, Volume 11, Issue 26, July 10, 2024.
The presence of colossal and reversible barocaloric effects in LiCB11H12, a renowned solid electrolyte, is evidenced near its order–disorder phase transition. It is observed that lattice vibrations primarily contribute to these barocaloric effects. Additionally, although the diffusion of lithium ions only marginally contributes to the accompanying ...

Barocaloric effects in ferroelectrics

open access: yes, 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

open access: yesResults 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.
