Berkeley Lab Scientists Develop a Cool New Method of Refrigeration

Adding salt to a road before a winter storm changes when ice will form. Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have applied this basic concept to develop a new method of heating and cooling. The technique, which they have named “ionocaloric cooling,” is described...

With Landmark Approval, Spotlight on Cryogenic Logistics Intensifies

The cell and gene therapy (CGT) industry achieved a significant milestone at the end of 2022: the first approval of an allogeneic T-cell therapy in the world. Following a positive recommendation from Europe’s Committee for Medicinal Products for Human Use (CHMP), the European Commission on Monday 19th December formally approved Atara Biotherapeutics’ Ebvallo...

New Instrument Measures Supercurrent Flow with Quantum Benefits

Jigang Wang offered a quick walk-around of a new sort of microscope that can help researchers understand, and ultimately develop, the inner workings of quantum computing. Wang, an Iowa State University professor of physics and astronomy who’s also affiliated with the U.S. Department of Energy’s Ames National Laboratory, described how the instrument works in extreme...

Cryomech Celebrates 60 Years of Cryo-Innovations

Cryomech was founded in 1963 by William E. “Bill” Gifford. Gifford was a professor at Syracuse University from 1961 to 1978 and (in collaboration with Dr. Howard O. McMahon) invented the Gifford-McMahon (GM) cycle cryo­cooler in 1957. This invention made research at very low temperatures much more accessible to the...

The “New” Space Mission–Cryogenic Bearings

Since the late 1990s, advancements in communication technology and the advent of GPS expanded the desire for companies and governments to invest in satellite technologies that operate in higher orbit. Today, companies like SpaceX, Blue Origin, Virgin Orbit, Relativity Space and ULA are developing cost-effective, reusable launch systems.  Manufacturers understand...

Why the LNG Retrofit Revolution Has Cryospain at Work Across Land and Sea

What is it about liquefied natural gas (LNG) for transport that has Cryospain’s teams hard at work across continents and oceans, on existing and brand-new vehicles and all over the world? Within the context of the global challenge of slashing emissions, LNG as fuel is taking a more and more...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of  the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

Air Separation and Liquefaction

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...

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...
