The term 'Cryogenics' applies to the study of materials at temperatures ranging from -100°C to almost absolute zero (-273°C). This is the range where gases turn into liquids; steel, even rubber, becomes as brittle as glass; metals become super-conductors and even living cells pass into a state of suspended animation. This research paper explains the concept in detail.
