New method shows electron pairs precede HTS

Using new imaging methods, scientists at Brookhaven National Laboratory have confirmed that electron pairs that carry electrical current emerge above the transition temperature before superconductivity sets in.

Organizations urge Obama to appoint White House Science Advisor

The American Institute of Physics, the American Physical Society and the American Astronomical Society were among 180 organizations that signed letters to President-Elect Barack Obama and Senator John McCain, urging them to appoint a White House Science Advisor by Inauguration Day.

PBS’ Independent Lens to air “The Atom Smashers” on Nov.25

On Tuesday, November 25, 2008 at 10:30 PM CST, PBS's Independent Lens will air a documentary called "The Atom Smashers." The film gives an in-depth look into particle physics, the Fermilab Tevatron, CERN's Large Hadron Collider and the search for the Higgs boson.

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...
