In the 1960s, Rochester continued to work at IBM, directing cutting edge research in cryogenics and tunnel diode circuits. Later he joined IBM’s Data Systems Division and developed programming languages and advanced computer science.

A plate-fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids. It is often categorized as a compact heat exchanger to emphasise its relatively high heat transfer surface area to volume ratio. The plate-fin heat exchanger is widely used in many industries, including the [...]
;Cryobiology: is the study of life at low temperatures. ;Cryogenics: is the branch of physics and engineering that studies the production and use of very low temperatures. Cryogenics is not cryonics, although people often confuse them. ;Cryonics: is the low temperature preservation of humans and mammals with the intention of future revival. Cryonics is not [...]
In an interview or commentary published in bilingual form (English and French) in a collection of his drawings (”blockBuster”, 2005) Buchet noted that science fiction had the peculiarity of “allowing a natural journey between past and future”. The science fiction traditions of cryogenics and social manipulation at a grand scale made it possible for him [...]
The LEF publishes a magazine monthly entitled ”Life Extension” that discusses health research and the use of dietary supplements. Part of the organization’s profits from the sale of supplements and membership dues is used to fund independent research aimed at discovering new therapies for slowing and reversing the aging process. Life Extension has provided financial [...]
Lew McCardle is a geologist working for Houghton Oil, which has reason to believe that there is oil in the far north. While running a test drill, the machine accidentally uncovers the frozen body of a man. Lew is given charge of the body, and he immediately calls his friend Semyon Petrovitch, who is a [...]
inversion temperature in thermodynamics and cryogenics is the critical temperature below which a non-ideal gas (all gases in reality) that is expanded at constant enthalpy will experience a temperature decrease, and above which will experience a temperature increase. This temperature change is known as the Joule-Thomson effect, and is exploited in the liquefaction of gases. [...]
The Swift’s high-velocity performance undoubtedly comes at a price, because the high velocities and high internal firing temperatures do accelerate chamber and bore wear. But modern metallurgy and cryogenics have vastly improved barrel life with the .220& Swift and other cartridges, although they still tend to require rechambering or rebarreling much sooner than lower-velocity cartridges [...]
When “Operation Flood” (a program to produce more milk in the country) was introduced in India, new technology from the Western world was adopted. One new implementation was storing bull’s semen in liquid nitrogen containers. The temperature of liquid nitrogen is minus 196 degrees Celsius. The liquid nitrogen containers are similar to thermos flasks used [...]
Liquefied gases, such as liquid nitrogen and liquid helium, are used in many cryogenic applications. Liquid nitrogen is the most commonly used element in cryogenics and is legally purchasable around the world. Liquid helium is also commonly used and allows for the lowest attainable temperatures to be reached. These liquids are held in either special [...]
Cryogenic cooling of devices and material is usually achieved via the use of liquid nitrogen, liquid helium, or a cryocompressor (which uses high pressure helium lines). Newer devices such as pulse cryocoolers and Stirling cryocoolers have been devised. The most recent development in cryogenics is the use of magnets as regenerators as well as refrigerators. [...]
