Researchers Investigate Reliability of Cryogenic Vacuum Distillation for Soil Water Extraction

The stable isotopes hydrogen and oxygen (δ2H and δ18O, respectively) in soil water are widely used in ecological studies, which rely on the accurate extraction of unfractionated water from different soil types. Cryogenic vacuum distillation (CVD) is the laboratory-based technique most widely used in eco-hydrological studies. However, the reliability of...

Cryogenic Bearings Smooth Way To ‘Greener’ Marine Power

The pressure to reduce greenhouse gas emissions continues as does the search for ‘greener energy solutions’ and one of the consequences of this is significant growth in the use of Liquid Natural Gas for marine applications. LNG has long been regarded as a sustainable fuel and has gained significant traction...

New Approach for the Identification of Metabolites Using LC with Ion Mobility and Cryogenic Spectroscopy

Researchers from Polytechnique Fédérale de Lausanne in Switzerland have developed a new approach for identifying isomeric and isobaric metabolites using high-resolution ion mobility spectrometry (IMS) and cryogenic infrared (IR) spectroscopy. The complex structure of metabolites has made their identification challenging, and analytical standards are often required to confirm their presence...

Chart Industries, Inc. and Crane Company Successfully Test a New Liquid Hydrogen Valve

Chart Industries, Inc. and Crane Company have successfully tested a new cryogenic valve designed and built by Crane for liquid hydrogen applications. This is the first valve launched from Crane’s CRYOFLO™ line of bellow seal vacuum jacketed globe valves, designed and tested by Crane, with final validation, review, and testing conducted...

Consortium Develops Cryogenic 4 K and 77 K Transistor Models

The Innovate UK-funded CryoCMOS Consortium, led by SureCore Ltd, reports that it has successfully created new, PDK-quality, transistor models characterized for both 4 K and 77 K cryogenic operation. SureCore is using these to develop key foundation IP to enable the design of cryo-control ASICs for use in the quantum...

4 Ways Cryogenic Applications of Helium Can Be Used

Helium is a gas with properties that make it useful for many different purposes, from cooling to providing lift in airships. By understanding the basics of its cryogenic principles, we can understand how this gas works and its various uses. The aspects of cryogenic science emerged in early 19th-century experiments by Faraday...

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...
