Cryogenics as a technique involves the generation, control, and application of extremely low temperatures, typically below −150 °C, to manipulate physical, chemical, or biological systems. It encompasses methods for liquefying gases (e.g., helium, hydrogen, nitrogen) using staged compression–expansion, Joule–Thomson cooling, and regenerative heat exchange, as well as thermal insulation strategies such as multilayer insulation and high-vacuum environments. Cryogenic techniques enable superconductivity studies, low-temperature spectroscopy, quantum device operation, and preservation or embrittlement of materials by stabilizing phases, suppressing thermal noise, and altering transport properties, while requiring precise management of thermal loads, cryogen boil-off, and material behavior at cryogenic temperatures.
With a Kobe University-developed procedure, induced pluripotent stem cells can now be frozen directly in their dishes without losing their viability or undifferentiated state after thawing. This marks a significant step for ...
