NASA’s SpaceX Crew-5 Launches to International Space Station

The crew members assigned to NASA’s SpaceX Crew-5 mission went into orbit following their launch to the International Space Station on Wednesday, October 5, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The international crew will serve as the agency’s fifth commercial crew rotation mission with SpaceX...

Cryogenic Blast Freezing in Minutes Increases Throughput

The biotech and biopharma industries utilize freezers to rapidly freeze and store thermally sensitive products such as vaccines and biopharmaceuticals as well as biological materials such as blood plasma. However, conventional compressor-based systems can take hours to reach an ultra-low target temperature, which slows production throughput.  For these industries, the...

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...

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...
