Kryogén

Kryogén is a term that refers to substances or processes operating at extremely low temperatures. These temperatures are typically far below what is encountered in everyday life, often in the range of hundreds of degrees Celsius below zero. The scientific field that studies these phenomena is called cryogenics.

The applications of kryogén are diverse and significant. In scientific research, cryogenics is essential for studying superconductivity, quantum mechanics, and the behavior of matter under extreme conditions. Medical applications include cryopreservation, where biological tissues and organs are stored at very low temperatures to preserve them for later use, such as in organ transplantation or fertility treatments. Cryosurgery, a medical procedure that uses extreme cold to destroy diseased or abnormal tissue, also falls under this umbrella.

Industrially, kryogén is used in various sectors. Liquefied gases like nitrogen and oxygen are produced and stored using cryogenic processes for use in welding, medical oxygen supply, and in the aerospace industry for rocket fuel. Magnetic Resonance Imaging (MRI) machines rely on superconducting magnets cooled to cryogenic temperatures to function. The development of technologies like magnetic levitation trains also involves cryogenic principles. The handling and storage of these extremely cold substances require specialized equipment and safety protocols due to the potential hazards associated with extreme cold, such as frostbite and material embrittlement.
