High-Efficiency Thermal Battery Regulated by Ultralow Magnetic Fields. [PDF]

Small Sci
A magneto‐responsive composite is reported that, for the first time, achieves a noncontact phase transition with an ultralow magnetic field (≈0.04 T). It exhibits a colossal entropy change of ≈507.6 J kg−1 K−1, an enthalpy of 181.1 J g−1, and a ≈47.6 K temperature rise, alongside enhanced thermal conductivity and heat‐release efficiency, making it ...

Barocaloric effect on graphene. [PDF]

Sci Rep, 2017
AbstractWe describe how mechanical strain is able to control the flow of heat on a graphene sheet, since this material can either absorb or expel heat from/to a thermal reservoir, depending on the strain energy. In a similar fashion as the magneto- and electro-caloric effects, the present case considers the fact that a mechanical strain produces a ...

Colossal barocaloric effects in plastic crystals [PDF]

Nature, 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

Impact of Controlled Magneto-Structural Coupling in MnCoGe-Based Compounds on the Design of Multifunctional Materials for Technological Advances. [PDF]

Adv Sci (Weinh)
In this work, the authors systematically investigate how Ni substitution regulates the magneto‐structural coupling and their functional consequences in the MnCoGe‐based compounds. Geometric nonlinear theory analysis reveals that Ni modification change of magneto‐structural transition can alleviate the lattice incompatibility, thereby broadening the ...

Barocaloric thermal batteries

, 2021
Nowadays the world is facing a prominent paradox regarding thermal energy. The production of heat accounts for more than 50% of global final energy consumption while the waste heat potential analysis reveals that 72% of the global primary energy consumption is lost after conversion mainly in the form of heat.

Giant barocaloric effect in neopentylglycol-graphene nanosheets composites with large thermal conductivity

Materials 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

Caloric effects around phase transitions in magnetic materials described by ab initio theory : the electronic glue and fluctuating local moments [PDF]

, 2020
We describe magneto-, baro-, and elastocaloric effects (MCEs, BCEs, and eCEs) in materials, which possess both discontinuous (first-order) and continuous (second-order) magnetic phase transitions.
