4 Ways Cryogenic Applications of Helium Can Be Used

Helium is a gas with properties that make it useful for many different purposes, from cooling to providing lift in airships. By understanding the basics of its cryogenic principles, we can understand how this gas works and its various uses. The aspects of cryogenic science emerged in early 19th-century experiments by Faraday...

Novel Cryogenic Nanopositioning Technique Progresses into the Quantum Sensing Decade

Quantum Sensing: Necessity for low temperature and low vibrations-Most quantum states are only visible and controllable when the thermal energy KBT is comparable or smaller than the energy difference ΔE between the quantum states. Therefore, to see the quantum properties of materials or devices, they often need to be cooled...

NASA’s Quantum Detector Achieves World- Leading Milestone

A new JPL- and Caltech-developed detector could transform how quantum computers located thousands of miles apart exchange huge quantities of quantum data. Quantum computers hold the promise of operating millions of times faster than conventional computers. But to communicate over long distances, quantum computers will need a dedicated quantum communications...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...
