CRESST uncovers hint of dark matter

Physicists are finally closing in on dark matter, the elusive substance thought to make up most of the matter in the universe. Either that, or they’re being misled by some unknown source of error.

New superconductor fibers carry 40 times more electricity

Wiring systems powered by highly efficient superconductors have long been a dream of science, but researchers have faced such practical challenges as finding pliable and cost-effective materials. Now researchers at Tel Aviv University (TAU) have found a way to make an old idea new with the next generation of superconductors.

Dr. Randall Barron and son complete new college-level engineering textbook

Dr. Randall Barron, professor emeritus of mechanical engineering at Louisiana Tech, and Dr. Brian Barron, lecturer in mathematics and statistics at Louisiana Tech, have completed “Design for Thermal Stresses” – a college-level engineering textbook that provides design tools that allow engineers to understand and alleviate potential problems involving thermal stresses.

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...
