Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

A Basic Science Breakthrough

A Yale-led team has found the strongest evidence yet of a novel type of superconducting material, a fundamental science breakthrough that may open the door to coaxing superconductivity — the flow of electric current without a loss of energy — in a new way. The discovery also lends tangible support...

Leon Cooper Dies at 94

Leon Cooper, who has died aged 94, helped to solve a problem that had stumped many of the greatest minds in twentieth-century physics. With his colleagues John Bardeen and Robert Schrieffer, he deciphered the dance of electrons that causes superconductivity, or the sudden drop in electrical resistance experienced by certain materials,...

Korean Scientists Achieve Unprecedented Real-Time Capture of Quantum Information

A research team led by Professor Jaedong Lee from the Department of Chemical Physics at DGIST (President Kunwoo Lee) has unveiled a groundbreaking quantum state and an innovative mechanism for extracting and manipulating quantum information through exciton and Floquet states. Collaborating with Professor Noejung Park from UNIST’s Department of Physics (President Chongrae...

Standex Bolsters Scientific Refrigeration With $6.2m CBS Cryogenic Deal

Standex International Corporation (SXI) has acquired Michigan-based advanced cryogenic equipment manufacturer Custom Biogenic Systems (CBS) for around $6.2m cash. Under terms of the deal, CBS will become part of SXI’s scientific business segment. CBS expertise includes the manufacturing of unique isothermal freezers with dry liquid nitrogen technology for the pharmaceutical and...

Danaher Cryo Releases Optimized Rodeo Control System

To complement its family of sub-Kelvin cryostats, Danaher Cryogenics announces the release of its new Rodeo Control System. In an elegant, compact package, the Rodeo Control System gives the user great functionality, including system configuration and control, data collection and graphing, and system status. The Rodeo system is composed of...

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...

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...

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...
