transmission electron cryomicroscopy cryotem , commonly known as cryo-em, is a form of cryogenic electron microscopy, more specifically a type of transmission electron microscopy tem where the sample is studied at cryogenic temperatures generally liquid-nitrogen temperatures . cryo-em is gaining popularity in structural biology.. the utility of transmission electron cryomicroscopy stems .
cryogenic hardening is a cryogenic treatment process where the material is cooled to approximately −185 c −301 f , usually using liquid nitrogen. it can have a profound effect on the mechanical properties of certain steels, provided their composition and prior heat treatment are such that they retain some austenite at room temperature.

a cryogenic storage dewar named after james dewar is a specialised type of vacuum flask used for storing cryogens such as liquid nitrogen or liquid helium , whose boiling points are much lower than room temperature.cryogenic storage dewars may take several different forms including open buckets, flasks with loose-fitting stoppers and self-pressurising tanks.
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.
