Cryo-EM at University of Cincinnati Reveals the Invisible and Transforms Structural Biology

By Megan Burgasser For the first time, researchers at the University of Cincinnati have visualized the structure of two key protein partners involved in inflammation and immune signaling. This breakthrough—published in the Proceedings of the National Academy of Sciences—not only uncovers the structure of the ADAM17 enzyme in complex with...

Tiny Cryogenic Device Cuts Quantum Computer Heat Emissions By 10,000 Times

Researchers have developed a tiny device that extinguishes one of the biggest heat sources in quantum computers, cutting their running costs and potentially bringing these machines closer to commercial reality. Most quantum computers operate at temperatures close to absolute zero (459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius) using specialized cooling equipment to...

U of W Teams Sets Record for ‘Cool’ Science’

Over the summer, Dr. Jeff Martin, chair of the physics department at the University of Winnipeg (U of W), tripled his past record for ultracold neutron production at TRIUMF, Canada’s particle accelerator centre. With the help of Dr. Russell Mammei, Dr. Blair Jamieson and several graduate and undergraduate students, Martin...

Nikkiso Contracted for Bahamas LNG-to-Power Project

Nikkiso Clean Energy & Industrial Gases Group has been contracted by NPG (a joint venture to be formed by Shell and a subsidiary of FOCOL Holdings Limited) to provide liquefied natural gas (LNG) regasification and cryogenic equipment for the New Providence Gas Project in Nassau, the Bahamas. The project involves...

Researchers Build Einstein Telescope Pathfinder with 10 km Arms and 10–15 K Cryogenic Mirrors

The search for gravitational waves continues to push the boundaries of precision measurement, and the next generation of detectors promises to reveal previously inaccessible cosmic events. Thomas Höhn, Adrian Schwenck, and Thomas Thümmler, from the Karlsruhe Institute of Technology, alongside the Einstein Telescope Pathfinder (ET-PF) collaboration, are developing crucial technologies...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

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...
