Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

Stirling Cryogenics’ World Tour

Given the theme of this issue of Cold Facts, Stirling Cryogenics would like to take you on a tour of our 70-year history, telling about our recent and vintage cryogenerators and systems all around the world. Universities worldwide have been our customers from the very beginning, cheering in the 1950s that...

Streamlining Industrial Gas Distribution with Cylinder Outsourcing

By streamlining the acquisition, recertification and repair of gas cylinders, industrial gas distributors can increase profitability. Industrial gas distributors, responsible for filling and supplying compressed gas cylinders for sale or rental, are crucial to diverse sectors. They deliver essential gases like nitrogen, oxygen, argon, carbon dioxide, hydrogen, helium, methane and...

Quantum Computing With a Revolutionary Superconducting Processor

Researchers at the Cleland Lab, part of the University of Chicago’s Pritzker School of Molecular Engineering (PME), have unveiled a groundbreaking design for superconducting quantum processors. This new architecture features a modular router that breaks free from the traditional two-dimensional grid constraints, enhancing qubit connectivity and scalability. The advancement...

Helium Conservation by Diffusion Limited Purging of Liquid Hydrogen Tanks

The NASA Engineering and Safety Center (NESC) has developed an analytical model that predicts diffusion between two gases during piston purging of liquid hydrogen (LH2) tanks. This model helps explain dramatic helium savings seen in a recent Kennedy Space Center (KSC) purge, shows that undesired turbulent mixing occurred in Space...

Dewar

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 Cryocoolers

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,...

Liquefied Natural Gas (LNG)

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...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
