Giant barocaloric effect in commercial polyurethane

open access: yesPolymer Testing, 2021
Barocaloric effect in polymers is barely recognized and limited to a few reports in the literature. This effect consists of a thermal response of the material when a hydrostatic pressure is applied, allowing its application in the field of solid-state ...

HgCdTe superlattices for solid-state cryogenic refrigeration [PDF]

open access: yesApplied Physics Letters, 2006
A tall barrier superlattice structure based on mercury cadmium telluride material system is proposed that can achieve a large effective thermoelectric figure of merit (ZTmax∼3) at cryogenic temperatures. Calculations based on the Boltzmann transport equation taking into account the quantum mechanical electron transmission show that the Seebeck ...

Solid-State Laser Refrigeration at GPa Pressures [PDF]

open access: yes, 2020
Although solid-state laser-refrigeration recently has been demonstrated to reach cryogenic temperatures in vacuum, to date the solid-state laser refrigeration of materials at elevated pressure conditions has remained unexplored. Here we demonstrate the laser cooling of ytterbium-doped yttirum-lithium-fluoride (10%Yb3+:YLiF4, or Yb:YLF)>17K below ...

Continuous-wave room-temperature diamond maser [PDF]

open access: yes, 2017
The maser, older sibling of the laser, has been confined to relative obscurity due to its reliance on cryogenic refrigeration and high-vacuum systems.

Giant room temperature elastocaloric effect in metal-free thin-film perovskites

open access: yesnpj Computational Materials, 2021
Solid-state refrigeration which is environmentally benign has attracted considerable attention. Mechanocaloric (mC) materials, in which the phase transitions can be induced by mechanical stresses, represent one of the most promising types of solid-state ...

Solid-state optical refrigeration to sub-100 Kelvin regime [PDF]

open access: yesScientific Reports, 2016
AbstractSince the first demonstration of net cooling twenty years ago, optical refrigeration of solids has progressed to outperform all other solid-state cooling processes. It has become the first and only solid-state refrigerator capable of reaching cryogenic temperatures and now the first solid-state cooling below 100 K.
