Bluefors Delivers 18 Cryogenic Systems to Japan’s New G-QuAT Quantum Center

Bluefors has announced the successful delivery and installation of 18 cryogenic systems for the Global Research and Development Center for Business by Quantum-AI Technology (G-QuAT) at the National Institute of Advanced Industrial Science and Technology (AIST). The opening of the G-QuAT center in Tsukuba, Japan, on May 18, 2025, marked...

Motor Protein Dynamics Guide Brain Disease Drug Targeting; Cryo-EM Technology at Work

The cell cytoskeleton is modulated by motor proteins, known as dyneins, that generate force and movement on microtubules to control a wide range of biological processes, including motility, cell division, and intracellular transport. Mutation of Lis1, a key dynein regulator, can lead to the rare mental developmental disorder lissencephaly, or...

Omani and Chinese R&D Entities to Study Hydrogen Liquefaction

The Sustainable Energy Research Centre (SERC), a prominent Omani research facility based at Sultan Qaboos University (SQU), has announced a partnership with China’s SinoScience Clean Energy Technology Co. Ltd. The collaboration aims to identify technologies that will enable the liquefaction of green hydrogen for export. SinoScience, headquartered in the Chinese...

For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. All the frozen water detected by Webb is paired with fine dust particles throughout the disk. The majority of the water ice observed is found where it’s coldest and farthest from the star. The closer to the star the researchers looked, the less water ice they found. NASA, ESA, CSA, Ralf Crawford (STScI)

NASA Webb Identifies Frozen Water in Young Star System

Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system. Now there is definitive evidence: Researchers confirmed the presence of crystalline water ice in a dusty debris...

South Korea to Invest $39.2M in Large-Scale Liquid Hydrogen Carriers

South Korea has announced plans to invest 55.5 billion won ($39.2 million) in the development of large-scale liquid hydrogen carriers, with the goal of launching a demonstration ship by 2027. The project is part of the country’s broader effort to take a leading role in the emerging global hydrogen economy....

Interlune Secures Helium-3 Agreements with Maybell Quantum and U.S. Department of Energy

Interlune, a U.S.-based space resources company, has signed landmark agreements to supply lunar-sourced helium-3 to both Maybell Quantum and the U.S. Department of Energy (DOE). Maybell Quantum will be Interlune’s first commercial customer, receiving thousands of liters of helium-3 annually from 2029 to 2035. The helium-3 will support Maybell’s advanced...

Mixed Refrigerant Cycles

Most cryogenic refrigeration systems, both large scale systems and cryocoolers, use helium as a working fluid. There are a number of advantages to helium, not the least of which is that helium remains a fluid down to the lowest achievable temperatures. In order to freeze helium, pressures of over 20...

Fountain Pumps and He II Phase Separators

Helium II (He II), the second liquid phase of the 4He isotope described in this column in Cold Facts Spring 2010 (http://2csa.us/he2), can be modeled as consisting of two interpenetrating fluids. One, the superfluid component, has zero viscosity and entropy and the other, the normal fluid component, has nonzero viscosity...

Turboexpanders

A vital technology in the refrigerators and liquefiers described in Cold Facts Volume 31 Number 3 is that of turboexpanders. These devices are rotating machines in which the process fluid (e.g., helium) does work against the turboexpander while moving from high pressure to a lower pressure and thus is cooled....

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...

Resistance to embrittlement at low temperatures

Could anyone advise me about resistance to embrittlement at low temperatures for the alloys in subject, i.e. does the CF10M perform like the CF8M in the same cryogenic service (-215F)? Amara Maafi Amara.Maafi@bg-group.com

Need help with temperature dependent model

I am a fourth-year student at New Zealand University. My name is Xu Ke. I have a project to generate a temperature dependent model for inductor, capacitor and diode by using PLECS. PLECS is software which acts as a toolbox for MATLAB. In my models, the temperature is very low,...

In what form is water available in LN2?

Does anybody know in what form water is available in LN2? There probably is a block of ice in the bottom of the tank. But as water comes in many shapes, I can imagine snow or crystals floating free in the LN2. When water is available in LN2, could small...

Separating gases using cryogenics

We are looking for some consulting engineers who understand how to separate gases using cryogenics. We have a new process which takes biomass and converts it to 5 gases and we need to separate these gases into their pure forms. Thanks for your help. Malcolm Draper Energy Research Group LLC...
