Young Professionals 2020 Part 1 introduces outstanding young professionals (under 40 years of age) who are doing interesting things in cryogenics and superconductivity and who show promise of making a difference in their fields.

Lancaster Team Tests LEGO® as Superior Sub-Kelvin Insulator

The Ultra Low Temperature Physics Group at Lancaster University in the UK has achieved the record for coldest LEGOs in the universe by cooling the plastic toys to 4 mK in early December. Dr. Dmitry Zmeev and PhD student Joshua Chawner tested the properties of four LEGO blocks and a...

Argonne Upgrades Enable Next-Generation Experiments

Building 203 looks unassuming, but behind—and beneath—its brick exterior, researchers are performing advanced experiments and developing support systems to answer some of physics’ biggest questions. In January, Cold Facts toured the physics building at Argonne National Laboratory (CSA CSM) in Lemont IL to learn more about the ongoing upgrades from...

Clean Energy Future: The Future is Getting Colder

From the developments in cryogenic applications over the last 20 years, we can see that the world in its technological workings is getting colder. But really, the world has been getting colder for the last 150 years as advancements in mastering cold have made steady progress. Liquid air for energy...

Introducing Cool Fuel: Fueling Cryogenics for the 21st Century!

There’s no shortage of cool project areas in cryogenics these days: space, quantum computing, fusion energy, clean energy and clean transport, to name a few. These are the fields that aspiring new engineers want to work in when they pass through my office. The irony is that our cool field...

Cryogenic Industrial Gas to Play Major Role in Alternative Clean Energy

While industrial gases and cryogenics have touched nearly every sector and industrial market for decades, the global push towards alternative clean energy technology is pushing cryogenics more rapidly than ever before. As part of this push, Circor (CSA CSM) is setting new standards for a hydrogen energy world. New 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...

Any experience with G-10 in an extremely cold environment?

I have a cryostat with closed cycle cryocooler attached. The case is aluminum with a G-10 spacer between the case and a stainless steel bellows that supports the cryocooler.

Designing a liquid oxygen bath

I’m designing a Liquid Oxygen Bath to place composite coupons in the bath and soak 96 samples for intervals of 8 hours, 24 hours, 7 days, 21 days, 42 days, 62 days and 90 days.

School science projects involving cryogenics and metallurgy?

Can you recommend any school science projects that would involve cryogenics and metallurgy?

Metallic Salts Normally Used to Produce Ultra-Low Temperatures?

Regarding the method known as the Adiabatic Demagnetization of Paramagnetic Salts: What metallic salts are normally used to produce the ultra-low temperatures used for near-absolute-zero cryogenic research? Which salts are the most efficient? Which make the best cooling agents? And which are used most commonly by physicists? I am looking...
