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...

LHC Art Exhibition Opens at the National Academy of Sciences

While the Large Hadron Collider (LHC) is technically tucked away in Geneva, visitors to a new art exhibition in Washington DC may have just been afforded the most unique view available of the facility. “Jonathan Feldschuh: Large Hadron Collider” is a collection of seven paintings inspired by the world’s largest...

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
