RIX Liquid Oxygen Generation Plant Supports US Navy’s Newest Aircraft Carriers

Aircraft carriers use highly concentrated gaseous and liquid oxygen for aviation and medical applications. These legacy systems consume large amounts of valuable ship space and require constant attention and adjustment to meet purity and production rates. With the development of USS Gerald R. Ford (CVN-78) – the “first-in-class” nuclear-powered aircraft...

New Glenn Completes Initial Cryogenic Testing at Launch Complex 36

Blue Origin continues to take big steps forward with its New Glenn orbital rocket as hardware rolls out to the launch pad, cryogenic testing begins, and the BE-4 engine gains a new test stand. The company still aims to launch New Glenn at least once in 2024. Over the past month,...

Maybell Quantum Announces $25 Million Series A Funding Led By Cerberus

Maybell Quantum (“Maybell”), the quantum infrastructure company, has closed a $25 million funding round led by an affiliate of Cerberus Capital Management, L.P. (“Cerberus”), a global leader in alternative investing. This investment marks the start of a pivotal chapter in Maybell’s development. With Cerberus’ financial backing and operational support, Maybell...

ISRO Achieves Big Milestone For Human Mission Gaganyaan’s Cryogenic Engine

The Indian Space Research Organisation (ISRO), the space agency of the government of India responsible for the country’s space research and exploration programs, has achieved a major milestone in the human rating of its CE20 cryogenic engine, which powers the cryogenic stage of the human-rated LVM3 launch vehicle for Gaganyaan human...

Surface Superconductivity Appears in Topological Materials

Researchers at the Leibniz Institute for Solid State and Materials Research at IFW Dresden, Germany, have found proof for surface superconductivity in a class of topological materials known as Weyl semimetals. Interestingly, the superconductivity, which comes from electrons confined in so-called Fermi arcs, is slightly different on the top and...

BV Approves Concept for a Full-Size Liquid Hydrogen Carrier

A consortium of French shipping, vessel design and energy companies have achieved approval in principle for a new membrane tank-based transport system for liquid hydrogen, including both the underlying containment technology and an initial vessel design. GTT, the longtime leader in membrane containment systems for LNG carriers, has designed a new...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
