INEOS Announces over €2 Billion Investment in Green Hydrogen Production

INEOS has announced that it is to invest more than €2 billion into electrolysis projects to make zero carbon, green hydrogen across Europe. Its first plants will be built in Norway, Germany, Belgium with investment also planned in the UK and France. The announcement was made on October 18. INEOS,...

Heating Up Quantum Science Education with Laser Cooling

A series of interactive workshops developed by Columbia University physicist Sebastian Will and STEMteachersNYC will give educators tips and tools to cover quantum science in their classrooms. If you imagine a laser, you might think of beams of light popping balloons or slicing through a metal slab like butter. Lasers...

Laurentis Energy Partners Launches Helium-3 Production

Laurentis Energy Partners, in the fall of 2021, launched its program to produce Helium-3 (He-3), a rare and valuable isotope used in quantum computing, neutron research, border security and medical imaging. Laurentis will obtain the He-3 from tritium stored at the Darlington Nuclear Generating Station, about 100 kilometers east of...

Three Argonne Scientists Elected American Physical Society Fellows

The American Physical Society (APS) Fellowship is an honor signifying recognition by one’s professional peers, awarded each year to less than one-half of 1% of APS members. Each nominee is evaluated by the fellowship committee of the appropriate APS division, topical group or forum. After review by the APS fellowship...

Scientists Achieve the Coldest Temperature Ever Recorded

The absolute coldest a substance can ever achieve then is when all molecular motion is stopped. This occurs at -459.67 °F / -273.15 °C, also known as absolute zero, or 0 degrees on the Kelvin scale. It was this limit that scientists at the University of Bremen, Germany, approached when...

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...

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...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

Suppliers of regenerator materials

I was looking for suppliers of regenerator materials. Can you please provide a list of vendors for: • Lead spheres • Bronze screen discs • Rare earth materials and spheres Thank you in advance for any help you can provide.

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
