Researchers Designing Safer Cryotherapy Devices

Researchers at the University of Texas at Arlington and the University of Texas at Austin are developing a state-of-the-art cryotherapy device, one that can stimulate blood flow to keep tissue healthy and minimize potential side effects, and what are believed to be the first formal protocols for effective and safe...

Cryofab Honored by Rothman Institute

The Rothman Institute has nominated Cryofab (CSA CSM), a manufacturer of cryogenic equipment, for New Jersey Family Business of the Year for 2015, recognizing the company's impact on the community and its perseverance, business success and commitment to family.

1st Asian ICMC and CSSJ 50th Anniversary Conference

ICMC (International Cryogenic Materials Conference) and CSSJ (Cryogenics and Superconductivity Society of Japan) have announced a new joint conference to be held during November 2016 in Kanazawa, Japan. Contributed, invited and plenary papers on a wide range of topics will be presented, including superconducting materials, wire, tapes and electronics; low-temperature...

Neutrinos on a Seesaw

Mass is a fundamental property of matter, but there’s still a lot about it we don’t understand—especially when it comes to the tiny masses of neutrinos. An idea called the seesaw mechanism proposes a way to explain the masses of these curious particles. If shown to be correct, it could...

Cornell Researchers Create First Self-Assembled Superconductor

After nearly two decades’ worth of research, a multidisciplinary team at Cornell has created a self-assembled, three-dimensional gyroidal superconductor. Ulrich Wiesner, a materials science and engineering professor who led the group, says it’s the first time a superconductor, in this case niobium nitride (NbN), has self-assembled into a porous, 3-D...

Phosphine as a Superconductor?

Phosphine is one of the newest materials to be named a superconductor, a material through which electricity can flow with zero resistance. Scientists first liquefied phosphine in 2015, squeezing it under high pressure in a diamond vice to achieve superconductivity, and now a group of researchers from the University of...

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...
