1st Asian ICMC and CSSJ 50th Anniversary Conference

ICMC (International Cryogenic Materials Conference) and CSSJ (Cryogenics and Superconductivity Society of Japan) have announced a new joint conference to be held during November 2016 in Kanazawa, Japan. Contributed, invited and plenary papers on a wide range of topics will be presented, including superconducting materials, wire, tapes and electronics; low-temperature...

Neutrinos on a Seesaw

Mass is a fundamental property of matter, but there’s still a lot about it we don’t understand—especially when it comes to the tiny masses of neutrinos. An idea called the seesaw mechanism proposes a way to explain the masses of these curious particles. If shown to be correct, it could...

Cornell Researchers Create First Self-Assembled Superconductor

After nearly two decades’ worth of research, a multidisciplinary team at Cornell has created a self-assembled, three-dimensional gyroidal superconductor. Ulrich Wiesner, a materials science and engineering professor who led the group, says it’s the first time a superconductor, in this case niobium nitride (NbN), has self-assembled into a porous, 3-D...

Phosphine as a Superconductor?

Phosphine is one of the newest materials to be named a superconductor, a material through which electricity can flow with zero resistance. Scientists first liquefied phosphine in 2015, squeezing it under high pressure in a diamond vice to achieve superconductivity, and now a group of researchers from the University of...

LHC Art Exhibition Opens at the National Academy of Sciences

While the Large Hadron Collider (LHC) is technically tucked away in Geneva, visitors to a new art exhibition in Washington DC may have just been afforded the most unique view available of the facility. “Jonathan Feldschuh: Large Hadron Collider” is a collection of seven paintings inspired by the world’s largest...

Argonne Scientists Inspire the Next Generation of Computational Thinkers

The City of Chicago and the US Department of Energy's (DOE's) Argonne National Laboratory (CSA CSM) came together this winter for a "My Brother's Keeper" event, a one-day hands-on workshop connecting the dots between computational thinking and science, technology, engineering and math (STEM) careers for 8th grade students attending the...

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...

Seeking alloy that keeps elastic property down to 10K

I am looking for a metal (alloy) that supports high temperatures (at least 1600K) and keeps its elastic property at low temperatures down to 10K. Rhenium is a good one because it does not become brittle. But it is quite expensive. Pure tungsten and molybdenum enter in the brittle regime...

Searching for a freezer that does not need electricity

I’m student of University of Barcelona. We do technical cryogenic research and we are searching for a cryogenic portable freezer that does not need electricity. We can’t find any company that offers something like this. The product we are looking for is the typical portable freezer for food or drinks...
