Scientists Use Pressure to Make Liquid Magnetism Breakthrough

Using two flat-top diamonds and a lot of pressure, scientists at Argonne National Laboratory (CSA CSM) have forced a magnetic crystal into a spin liquid state, which may lead to insights into high temperature superconductivity and quantum computing.

CERN Researchers Create, Study New Exotic Atom at Paul Scherrer Institute

A team of researchers from CERN’s Atomic Spectroscopy and Collisions Using Slow Antiprotons (ASACUSA) collaboration have taken experimental equipment from CERN to the Paul Scherrer Institute near Zurich to create a theoretically predicted, but never before verified, exotic atom and made first measurements of how it absorbs and resonates with...

Scottish Homes to Be Heated by ‘100% Green’ Hydrogen Gas

Households in Scotland could be using “100% green” hydrogen for cooking and heating if plans for a new world-first gas network are approved. Under the proposal from gas distribution network company SGN, an initial 300 homes in Levenmouth will have access to clean hydrogen within two to three years.

Coldest Material in the Cosmos Could Help Scientists Find Dark Matter Particles

Researchers suggest the coldest material in the universe could reveal the presence of dark matter particles. In a new paper published early May in the journal Physical Review Letters, a group of Spanish scientists suggests magnetometers made using Bose-Einstein Condensates could be used to detect exotic spin-dependent forces. Bose-Einstein Condensates...

Mactac Unveils New Cryogenic Labels

Mactac, a North American adhesives, label and packaging company, has launched new cryogenic labelstocks for temperatures as low as -320º F. Mactac’s cryogenic labelstocks are intended for harsh environment applications where labels must withstand exposure to liquid nitrogen or ultralow temperature freezers, thaw cycles, chemicals and solvents.

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Specs and info on turbo expanders

I am a fourth year chemical engineering student doing a design project for the liquefaction of natural gas to DME and we are using a turbo expansion unit. I was wondering whether you would send me some specs and any additional information on turbo expanders that I could use as...

Colleges that offer cryogenic studies

Would you happen to know of any colleges in the US that offer cryogenics as a major? If not, should I major in something like biology or physics before, then branch off to the field of cryogenics? Any information that you could give me would be greatly appreciated, considering this...

Data on hardness of Indium?

Where can I find experimental data on the hardness of Indium, as a function of temperature, as well as any existing data on the thermal contact conductance of junctions containing Indium foil, also as a function of temperature?
