Chart Industries Acquires Hetsco

Chart Industries, Inc. has acquired Hetsco, Inc. in a $22 million deal made through its subsidiary, Chart Lifecycle, Inc. The move, according to a Chart statement, supplements the company's current offerings by bringing a full suite of welding services for industrial gas and gas processing facilities including mission critical repair,...

Toward a Standardized ODH Analysis Technique

Standardization of ODH analysis and mitigation policy thus represents an opportunity for the cryogenic community. There are several benefits for industry and government facilities to develop an applicable unified standard for ODH. The number of reviewers would increase, and review projects across different facilities would be simpler. It would also...

Whole Body Cryotherapy

Interest in low temperature treatment is increasing and whole body cryotherapy (WBC) devices are becoming available not only in medical centers but also in local gyms and spa centers. Many governments and medical professionals have thus turned attention to WBC, evaluating the treatment for its effectiveness and safety. The US...

Help Us Celebrate Women in Cryogenics and Superconductivity

We're looking for input for our February issue of Cold Facts. Participants are invited to answer the questions posted below and send their answers to Brian Dudley, Cold Facts Editor, editor@cryogenicsociety.org, by January 27.

CERN Ramps Up Neutrino Program

In the midst of the verdant French countryside looms a workshop the size of an aircraft hangar. Inside, CERN technicians are busy constructing two 8-meter tall cubes to test prototype detectors for the Deep Underground Neutrino Experiment (DUNE). Each will in time contain 770 metric tons of liquid argon permeated...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...

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...
