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...

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

Cryogenic Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
