Element Strengthens Cryogenic and Hydrogen Testing Capacity

UK-based testing, inspection and certification services provider the Element Materials Technology Group (Element) has announced that it will expand its cryogenic testing capacities at its Milan laboratory. By investing in new fatigue testing frames, Element will strengthen its position in both aerospace and the energy sector by offering testing for hydrogen...

The Magneto-Optic Modulator

Many state-of-the-art technologies work at incredibly low temperatures. Superconducting microprocessors and quantum computers promise to revolutionize computation, but scientists need to keep them just above absolute zero (-459.67° Fahrenheit) to protect their delicate states. Still, ultra-cold components have to interface with room temperature systems, providing both a challenge and an...

Allen Dufort: Coding a cutting-edge space telescope

In July, as the world marveled at the first images of the Cosmic Cliffs and previously invisible areas of star birth revealed by the James Webb Space Telescope, Allen Dufort felt excited that he’d soon make his own contributions to space exploration. As a software engineer intern, Dufort is supporting Brown...

Cryogenic Operation of LEDs Results in Improved Quantum Efficiency

Terrestrial gravitational wave detectors have been used to identify various gravitational wave sources. For example, researchers have detected potential black hole neutron star mergers, binary neutron star inspirals, and binary black hole mergers via the advanced Laser Interferometer Gravitational-wave Observatory (LIGO). The aLIGO detectors’ most sensitive band is limited by thermal...

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...

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...

Designing a liquid oxygen bath

I’m designing a Liquid Oxygen Bath to place composite coupons in the bath and soak 96 samples for intervals of 8 hours, 24 hours, 7 days, 21 days, 42 days, 62 days and 90 days.

Metallic Salts Normally Used to Produce Ultra-Low Temperatures?

Regarding the method known as the Adiabatic Demagnetization of Paramagnetic Salts: What metallic salts are normally used to produce the ultra-low temperatures used for near-absolute-zero cryogenic research? Which salts are the most efficient? Which make the best cooling agents? And which are used most commonly by physicists? I am looking...
