    A Cryogenic processor is a unit designed to reach ultra-low temperatures (usually around −300 °F −150 °C) at a slow rate in order to prevent thermal shockto the components being treated. The first commercial unit was developed by Ed Busch in the late 1960s. The development of programmable microprocessor controls allowed the machines to follow temperature profiles that greatly increased the effectiveness of the process. Some manufacturers make cryoprocessors with home computers to define the temperatur

  • Cryogenic treatment Wikipedia

    Cryogenic hardening. Cryogenic hardening is a cryogenic treatment process where the material is slowly cooled to very low temperatures. By using liquid nitrogen, the temperature can go as low as −196 °C. It can have a profound effect on the mechanical properties of certain materials, such as steels or tungsten carbide.

    Deep reactive-ion etching (DRIE) is a highly anisotropic etch process used to create deep penetration, steep-sided holes and trenches in wafers/substrates, typically with high aspect ratios.It was developed for microelectromechanical systems (MEMS), which require these features, but is also used to excavate trenches for high-density capacitors for DRAM and more recently for creating through

  • Cryogenic engineering Wikipedia

    Cryogenic engineering is a sub stream of mechanical engineering dealing with cryogenics, and related very low temperature processes such as air liquefaction, cryogenic engines (for rocket propulsion), cryosurgery.Generally, temperatures below cold come under the purview of cryogenic engineering. Cryogenics may be considered as the recent advancement in the field of refrigeration.

  • Joule–Thomson effect Wikipedia

    History. The effect is named after James Prescott Joule and William Thomson, 1st Baron Kelvin, who discovered it in 1852.It followed upon earlier work by Joule on Joule expansion, in which a gas undergoes free expansion in a vacuum and the temperature is unchanged, if the gas is ideal.. Description. The adiabatic (no heat exchanged) expansion of a gas may be carried out in a number of ways.

    Cryo-preservation or cryo-conservation is a process where organelles, cells, tissues, extracellular matrix, organs or any other biological constructs susceptible to damage caused by unregulated chemical kinetics are preserved by cooling to very low temperatures (typically −80 °C using solid carbon dioxide or −196 °C using liquid nitrogen). At low enough temperatures, any enzymatic or
