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.
Researchers at NYU Abu Dhabi (NYUAD) have developed an innovative tool that enhances surgeons' ability to detect and remove cancer cells during cryosurgery, a procedure that uses extreme cold to destroy tumors. This breakthrough ...
