anyone Know anything on Cryogenics?

Answer 1

Cryogenics is a branch of physics (or engineering) that studies the production of very low temperatures (below –150 °C, –238 °F or 123 K) and the behavior of materials at those temperatures. Cryogenics is also a popular misnomer for cryonics.

The word cryogenics literally means "the production of icy cold"; however the term is used today as a synonym for the low-temperature state. It is not well-defined at what point on the temperature scale refrigeration ends and cryogenics begins. The workers at the National Institute of Standards and Technology at Boulder, Colorado have chosen to consider the field of cryogenics as that involving temperatures below –180 °C (93.15 K). This is a logical dividing line, since the normal boiling points of the so-called permanent gases (such as helium, hydrogen, neon, nitrogen, oxygen, and normal air) lie below -180 °C while the Freon refrigerants, hydrogen sulfide, and other common refrigerants have boiling points above -180 °C.

Recent research regarding superconductivity at low temperatures has been called cryoelectronics, and the utilization of these sciences is called cryotronics.

Answer 2

Cryogenics is the study of low temperature (absolute zero) and its effects on various materials. Basically what happens to parts that are Cryo-treated, is as they are submerged in the liquid gas (Helium-coldest, Hydrogen, and Nitrogen) the actual molecules of the part are condensed making the material denser and more durable.
