CryoHiVac Investigates Cryogenic Market, Affordability from Earth to Space

Today’s time-sensitive market needs revolutionization of traditional costly technologies. The cryogenic and electronic market development and utilization started from 1970 for commercial applications, and both are fast-growing technologies. There has been significant advancement of electronic products. Nowadays, a small smartphone has much more data storage and processing power capability than...

Demaco Produces ESS Hydrogen Distribution System

Hydrogen is the most abundant chemical element in the universe and the most important feedstock for life. In Greek, the word “hydrogen” is composed of the terms “hydro” and “genes,” which means water generator. In 1766, the English chemist Henry Cavendish distinguished hydrogen from other flammable gases and identified its properties,...

Ability Engineering Technology Introduces Ultra Precise Cryo Valve to Public

Ability Engineering Technology (AET), an Illinois-based manufacturer of equipment used in cryogenic process applications, has announced the introduction of a standard product line of Cryogenic Valves. According to Matt Resler, Sales Director at AET, “Our cryogenic valves have been successfully used for more than 30 years by our DOE clients, and...

Space Cryogenic Workshop Recap

During a year filled with uncertainty, many were worried about the effects of the pandemic on CSA’s biennial Space Cryogenics Workshop (SCW). After much consideration and effort, we are pleased to report the successful execution of our first – and hopefully only – virtual SCW. Hosted virtually on the Remo®...

Fermilab Sees Record Performance from Next-Generation Accelerator Componen

For several years, three US Department of Energy national labs have worked together to further improve state-of-the-art particle accelerator technology. First tests of a prototype built at Fermi National Accelerator Laboratory (Fermilab, CSA CSM) show the effort has paid off, with a new component setting records. The technology under development...

Joule-Thomson Effect

The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...

Current Leads

One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...

Multilayer Insulation

Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...

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...

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?...

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...
