NIST scientists create the first controllable atom SQUID

Scientists have created the first controllable atomic circuit that functions analogously to a superconducting quantum interference device (SQUID) and allows operators to select a particular quantum state of the system at will. By manipulating atoms in a superfluid ring thinner than a human hair the investigators were able for the...

Taylor-Wharton International, LLC, a world-leading technology, service and manufacturing network for gas applications involving pressure vessels and precision valves, has announced promotions and additions within its CryoScience Management Team.

Accident exposes LN2 cocktails as a serious danger

Bars in the UK are being warned of the potential dangers of LN2 cocktails after an accident involving an 18-year-old in a Lancaster bar in early October.

The Cryogenic Institute of New England receives ISO 9001:2008 certification

The Cryogenic Institute of New England, Inc., a leading provider of Cryogenic Services such as cryogenic deflashing and deburring, cryogenic treatment, thermal cycling and dry ice blast cleaning, has received its registration from National Quality Assurance, U.S.A., after assessment of the company’s quality system and found it to be in...

Air Liquide expands its growth in Brazil with two recent contracts

Air Liquide Brazil has recently signed two contracts with major regional firms: Coca-Cola bottler FEMSA and Suzano Papel e Celulose, investing nearly US$ 90 million (€70 million) to develop the two projects.

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

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...

Information about a process called “cryogenically stretch-formed ss”

I am remembering in the 1970’s when astronauts were walking on the moon and carried oxygen in 300 ss bottles inside LN2 tanks which were filled and pressurized.

Small cryo-gun for our health service clinic

Additional sealing materials besides PTFE or glass filled PTFE

I am an engineer looking to improve our solenoid valve sealing on cryogenic medias. I was wondering if you knew of materials other then PTFE or glass filled PTFE that could be used for sealing.

What is the temperature range of cryogenics?

Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
