THERMAG VII 2016- 7th International Conference on Magnetic Refrigeration at Room Temperature

Untitled

7th International Conference on Magnetic Refrigeration at Room Temperature, Thermag VIIIn recent years, magnetic refrigeration around room temperature has received renewed interest thanks to the development of materials with enhanced magnetocaloric effects and, in parallel, developments in thermal engineering techniques. The potential high efficiency and environmental compatibility of magnetic refrigeration make this method of cooling a future competitor to conventional gas compression technologies.Thermag, the International Conference on Magnetic Refrigeration at Room Temperature, founded in 2005, representsthe state of the art in the field of new magnetocaloric materials and novel cooling techniques.

Giant barocaloric effect in hexagonal Ni2In-type Mn-Co-Ge-In compounds around room temperature : Scientific Reports

The most widespread cooling techniques based on gas compression/expansion encounter environmental problems. Thus, tremendous effort has been dedicated to develop alternative cooling technique and search for solid state materials that show large caloric effects. An application of pressure to a material can cause a change in temperature, which is called the barocaloric effect. Here we report the giant barocaloric effect in a hexagonal Ni2In-type MnCoGe0.99In0.01compound involving magnetostructural transformation, Tmstr, which is accompanied with a big difference in the internal energy due to a great negative lattice expansion(ΔV/V ~ 3.9%)
