SVC Partners with ASM International

The Society of Vacuum Coaters (SVC) and ASM International have announced the formation of a strategic alliance designed to bring the complementary strengths of both organizations together to better serve their global members and the community at large. As part of the alliance, ASM will begin providing comprehensive association management...

Air Liquide Upgrades, Expands Texas Complex

Air Liquide has completed a major upgrade and expansion of its Bayport industrial complex located just east of Houston. The complex covers 88 acres of land and supplies oxygen, nitrogen, argon, hydrogen, electricity, steam and industrial and demineralized water to customers in many industries. The facility is central to Air...

Scientists Observe Elusive Cooper Pairs, Confirm 50-Year-Old Prediction

An international scientific team has produced the first direct evidence of a Cooper pair density wave, a state of electronic matter first predicted by theorists in 1964. The discovery, described in a paper published in Nature, may provide key insights into the workings of high temperature superconductors.

Fermilab Welcomes Baby Bison with Naming Puns

Fermilab welcomed its first baby bison of 2016 on April 26 and by the next day a herd of its social media followers were birthing puns in a tongue-in-cheek #BisonNaming contest. Fermilab suggested the first name, Neil EatdeGrasse Bison, and followers took it from there. Suggestions included Higgs Bison, Bisotron,...

Researchers Look to Super-Spintronics for Future Computing

A University of Cambridge led project aims to develop a new architecture for future computing based on superconducting spintronics. Researchers on the project, dubbed Superspin, say it will pave the way for a new generation of ultralow power supercomputers capable of processing vast amounts of data at a fraction of...

Cryogenic Heat Exchangers for Space Exploration

Indian Space Research Organization (ISRO) is perhaps one of the most cost efficient satellite launching organizations in the world today. The two principal series of launch vehicles it uses are the Polar Satellite Launch Vehicle (PSLV) and the Geo Synchronous Launch Vehicle (GSLV). GSLV has three stages, the third of...

Latest in Defining Cryogenics

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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...

Seeking alloy that keeps elastic property down to 10K

I am looking for a metal (alloy) that supports high temperatures (at least 1600K) and keeps its elastic property at low temperatures down to 10K. Rhenium is a good one because it does not become brittle. But it is quite expensive. Pure tungsten and molybdenum enter in the brittle regime...

Searching for a freezer that does not need electricity

I’m student of University of Barcelona. We do technical cryogenic research and we are searching for a cryogenic portable freezer that does not need electricity. We can’t find any company that offers something like this. The product we are looking for is the typical portable freezer for food or drinks...

FEP Encapsulated O rings in the cryogenic process

Can you please advise if FEP Encapsulated O rings are used within the cryogenic process and what materials? I have been asked by my company to write about FEP Encapsulated O rings for a training seminar.

Need material property data for polycrystalline / sintered ceramics

I am a ME grad student currently working on the design of a detector array / focal plate of a scientific space instrument operating at a temperature of about -80…-100°C. Although this is not in the cryogenic temperature range, I would like to address two questions to you as the...
