New Thermometer Measures Cryogenic Temperatures at Submicron Scales
Taking the temperature of a sample can be tricky—especially in the regimes of the very small and the very cold. The smaller the sample, the greater the influence the thermometer itself may exert on the measurement. And in the ultracold regime, even tiny amounts of heat can significantly alter the...

Nanoparticles Show Quick and Easy Way to Target Cancer
Researchers have been exploring the use of injectable nanoparticles that can quickly home in on a microscopic tumor. It’s a novel technique that could pave the way for the early detection of small tumors that may not show up on traditional imaging technologies. In a study published in the October issue of...
Researchers Simplify Switching for Quantum Electronics
A quantum cousin of the Hall effect could open the door to energy-efficient electronics, better sensors, and more-powerful quantum computers. Researchers have now broken a key barrier to its practical application by controlling the phenomenon electrically, rather than magnetically, for the first time. The Hall effect, discovered by physicist Edwin...
ATLAS Measures Strength of the Strong Force with Record Precision
Binding together quarks into protons, neutrons and atomic nuclei is a force so strong, it’s in the name. The strong force, which is carried by gluon particles, is the strongest of all fundamental forces of nature – the others being electromagnetism, the weak force and gravity. Yet, it’s the least...

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...
Air Separation and Liquefaction

You are encouraged to read Cryo Central’s History...
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...
Cryogenic Finishing
The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
Cryogenic processing for medical equipment, mining industry
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.
Cryogenic sealant for LNG fueled buses?
Where can I find a cryogenic sealant for my LNG fueled buses?
Material/gel/epoxy to transfer cold temperature of a cryo-box to a test article
I’m on the hunt for a material/gel/epoxy that will transfer the cold temperature of a cryo-box to a test article. The cryo-box is curved and the test article is at the same curvature. I’m looking for something to put between them to make the surface of the test article as...
