Cryogenic

Cryogenic refers to the study and production of very low temperatures, typically below -150°C (-238°F), and the materials and technologies used in these conditions. This encompasses the properties of matter at these frigid levels, including superconductivity, the behavior of gases and liquids, and the preservation of biological samples. Cryogenics is critical for various applications, from rocket fuel storage to medical preservation.

Cryogenic meaning with examples

• The rocket's engines relied on cryogenic fuel, supercooled liquid hydrogen and oxygen, for efficient combustion and thrust. Engineers meticulously designed the fuel tanks and supply systems to maintain these extremely low temperatures throughout the flight, preventing vaporization.
• Medical researchers utilized cryogenic techniques to preserve stem cells for future therapeutic applications. These cells were rapidly frozen and stored in liquid nitrogen, ensuring their viability for potential treatments decades later, avoiding degradation.
• The MRI machine employed cryogenic cooling systems to maintain the superconducting magnets needed for its operation. These powerful magnets produce the magnetic fields required to generate detailed images of the body's internal organs and structures.
• Scientists studied the unusual properties of materials at cryogenic temperatures, such as their resistance to electrical current or their magnetic levitation, to understand the basic science behind this behavior.
