Giant barocaloric effects at low pressure in ferrielectric ammonium sulphate
Pol Lloveras,Enric Stern-Taulats,Maria Barrio,J. Ll. Tamarit,S. Crossley,Wei Li,Wei Li,Vladimir Pomjakushin,Antoni Planes,Ll. Mañosa,Neil D. Mathur,Xavier Moya,Xavier Moya +12 more
TL;DR: Small changes in hydrostatic pressure are used to drive giant inverse barocaloric effects near the ferrielectric phase transition in ammonium sulphate, and these effects and strengths are found that exceed those previously observed near magnetostructural phase transitions in magnetic materials.

Influence of elastic anisotropy on structural nanoscale textures.
TL;DR: It is shown that tweed occurs in the limit of high elastic anisotropy while a nanocluster phase-separated state occurs for values of an isotropy inhibiting the formation of martensite.
Colossal barocaloric effects near room temperature in plastic crystals of neopentylglycol
Pol Lloveras,Araceli Aznar,Maria Barrio,Philippe Négrier,Catalin Popescu,Antoni Planes,Lluís Mañosa,Enric Stern-Taulats,Alex Avramenko,Neil D. Mathur,Xavier Moya,Josep-Lluís Tamarit +11 more
TL;DR: In this paper, it was shown that plastic crystals of neopentylglycol (CH3)2C(CH2OH)2 display unprecedentedly large pressure-driven thermal changes near room temperature due to molecular reconfiguration, and these changes are comparable with those exploited commercially in hydrofluorocarbons.
Reversible and irreversible colossal barocaloric effects in plastic crystals
Araceli Aznar,Pol Lloveras,Maria Barrio,Philippe Négrier,Antoni Planes,Lluís Mañosa,Neil D. Mathur,Xavier Moya,Josep-Lluís Tamarit +8 more
TL;DR: In this article, the reversible barocaloric response of four plastic crystals derived from neopentane [C(CH3)4] was determined, and the minimum pressure needed to achieve reversible effects, prev, for each compound was determined using the quasi-direct method.
