Young Professionals 2021 introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields.
Prompted by the pandemic’s “new normal,” South Holland IL-based Ability Engineering Technology (AET, CSA CSM) has adopted a remote commissioning procedure in response to the pandemic’s continuously changing directives. AET has adopted a remote, data-based training approach to improve their commissioning abilities and product line.
This is the first part of a two-part article about cryogenic electronics, the operation of electronic devices, circuits and systems at temperatures considerably below the “standard” electronics lower limit of −55° C. Alternative names are cryoelectronics, cold electronics and low-temperature electronics. Presented by Dr. Randall Kirschman.
CSA regrets to report the loss of one of our own. Former Cold Facts editor Brian Dudley passed away peacefully in Tallahassee FL on January 9, 2021. He was 45.
Cornell scientists have identified a new contender when it comes to quantum materials for computing and low temperature electronics. Using nitride-based materials, the researchers created a material structure that simultaneously exhibits superconductivity—in which electrical resistance vanishes completely—and the quantum Hall effect, which produces resistance with extreme precision when a magnetic...
A team of scientists has detected the presence of a high-energy neutrino—a particularly elusive particle—in the wake of a star’s destruction as it is consumed by a black hole. This discovery, reported in the journal Nature Astronomy, sheds new light on the origins of Ultrahigh Energy Cosmic Rays—the highest energy...
A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...
Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...
A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...
F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...
Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Abstract: Cryosurgery is a surgical technique that employs freezing...
Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...
Greetings from Australia. I am looking for a company that I might contact that has any experience or has done any research into cryogenic processing for medical equipment, in particular, joint prosthesis.
