Below 10 K one uses magnetic materials which are specially developed for this application. The so-called coefficient of performance (COP; denoted ξ {\displaystyle \xi } ) of coolers is defined as the ratio between the cooling power Q ˙ L {\displaystyle {\dot {Q}}_{\text{L}}} and the compressor power P .
Magnetocaloric effect (MCE): This effect involves a temperature change in a material due to a change in magnetic field. It is based on the magnetocaloric materials' ability to undergo an entropy change when subjected to a magnetic field, which aligns magnetic domains and reduces entropy, leading to heating or cooling.
Discovery of a new class of materials that could make magnetic refrigeration a viable cooling technology for the future. Development of a high-strength lead-free solder that is stronger, easier to use, stands up better in high-heat conditions, and is environmentally safe.
MP Materials and Australia's Lynas held a confidential discussion regarding a potential merger which fell through on February 5, 2024. [28] Lynas is the second largest rare earth material company outside of China. As of 2024, CEO James Litinsky was the company's largest shareholder. [29]
Special magnetic nanofluids with tunable thermal conductivity to viscosity ratio can be used as multifunctional ‘smart materials’ that can remove heat and also arrest vibrations (damper). Such fluids may find applications in microfluidic devices and microelectromechanical systems ( MEMS ).
Sealy. New to Cocoon by Sealy’s collection, this hybrid mattress features a premium stretch-knit cover infused with Phase Change Material that helps you fall asleep faster at a cooler temperature.
Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.
