The paper systematically reviews developments of novel heat switches at cryogenic temperatures, which can alternatively provide high thermal connection or ideal thermal isolation to the cold mass. These cryogenic heat switches are widely applied in a variety of unique superconducting systems and critical space applications. The discussion and review will include the following technical...
Additive manufacturing techniques using composites or metals are rapidly gaining momentum in cryogenic applications. Small or large, complex structural components are now no longer limited to mere design studies but may move into the production stream thanks to new machines on the market that allow for light-weight, cost optimized designs with short turnaround times. The potential for cost...
High-temperature ionic salts are central to several promising technologies for green energy and industrial synthesis: concentrated solar power, safe nuclear fission, and high-temperature batteries for smart grid applications.
Several methods used for thermal management in cryogenics have been used to solve critical design challenges that have until now inhibited those technologies.
The methods...
The cryogenic distillation has long been applied in the extensive production of industrial gases because of its features of high efficiency, high purity, and capability to produce noble gases, and it still plays a dominant role at present. Exploring methods to improve the mass transfer efficiency in cryogenic distillation is of great theoretical and practical significance. The negative...
Attaining cooling effect by using laser induced anti-Stokes florescence in solids appears to have several advantages over conventional mechanical systems and has been the topic of recent analysis and experimental work. Using anti-Stokes fluorescence phenomenon to remove heat from a glass by pumping it with laser light, stands as a pronouncing physical basis for solid state cooling. Cryocooling...
