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...

Air Liquide Sets Record Signings for Small On-Site Gas Units

In 2023, Air Liquide set a new record by signing 62 new small gas production units directly installed on its customers’ sites in the industrial merchant and electronics sectors in 2023. This growth reflects the increased demand for these solutions, and illustrates our capacity to meet customers’ needs. They offer real...

Lockheed Martin Looks to Space with Australian-Developed Composite Tanks

In a groundbreaking collaboration, Lockheed Martin, Omni Tanker and UNSW Sydney have joined forces to pioneer and commercialize world-first composite tank technologies. This ambitious project, supported by a grant from the Federal Government’s Advanced Manufacturing Growth Centre (AMGC), aims to tackle the challenges associated with using composites for the transportation...

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...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

Dry ice vs. LN2 for preserving tissue

I was wondering if anyone could provide feedback/data on whether it is best in terms of preserving tissue quality to freeze tissue in OCT using dry ice versus liquid nitrogen?

Are there lists of existing biorepositories?

We are a relatively new Biorepository that was developed as part of a large breast cancer epidemiology study, and thus far we have accumulated DNA on over 8000 women along with extensive questionnaire, mammography, and case status data. I was wondering, are there lists of existing Biorepositories with their contents?...

Heat flux value for inner vessel when vacuum insulation fails

To size a relief valve for a LN2 cryostat I have to know “worse case” boil-off rate when vacuum insulation failed and inner vessel with LN2 is in direct contact with room temperature air at 300K. So, I am looking for a heat flux value (watt/m2) to LN2 inner vessel...

Trying to design a system to store ammonia at -33°C

I am working on a project where we are trying to design a system to store ammonia at -33°C. In order to size the compressors to maintain the ammonia in the liquid state, I need to estimate the heat gained from the environment including the radiation from the sun and...
