New Study Reveals When a Superconductor Truly Becomes Super

Unraveling the mystery of superconductivity at high temperatures, specifically in copper oxide materials, remains one of the most puzzling challenges in modern solid-state physics. But new multinational research has confirmed the existence of a copper-oxide-based (or cuprate) phase transition at a temperature close to absolute zero (-273°C).

SPHEREx Mission Selected to Uncover Origins of the Universe

NASA's Astrophysics Explorers Program and associated divisions are moving ahead with a new space mission designed to help astronomers understand both how our universe evolved and how common the ingredients for life are in our galaxy’s planetary systems.

New Ceramic Material Can Better Withstand Extreme Temperatures

UCLA researchers and joint collaborators have created an extremely light and very durable ceramic aerogel, a new material that could be used for applications like insulating spacecraft due to its ability to withstand severe temperature changes encountered on space missions.

CERN Focused on Transforming LHCb and Upgrading ALICE

A period of maintenance and upgrade work is well underway at CERN, part of a technical break called Long Shutdown 2. Planned LS2 projects involve either upgrading or replacing sub-detectors at ALICE, while the Large Hadron Collider team is focused on increasing the proton–proton collision rate at LHCb by a...

Success after a Three-year Sprint

ProtoDUNE scientists rushed to develop the project’s first large prototype detector, resulting in an amazing display of the technology being created for the Deep Underground Neutrino Experiment.

UCSD Students Prepared to Launch Vulcan II

A team of engineering students from UC San Diego has developed a test rocket that features a 3D printed engine that incorporates liquid oxygen and kerosene RP-1. The updated rocket is called Vulcan II, and represents a vessel the students will attempt to launch roughly six miles into the atmosphere...

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...

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...
