Cool Fuel: Hydrogen, Lenses and Lasers, Oh My!

The bar for getting the suffix of PhD after your name is high – you have to fundamentally change the philosophy in a field. As a faculty member responsible for training some of these individuals, I’m sometimes faced with the conundrum that advancing the philosophy implies that I have to...

Groundbreaking Alternative to Invasive Breast Cancer Surgery Now Available in Monroe NJ

Patients in Central New Jersey with early-stage breast cancer can now access a highly effective treatment that does not require traditional invasive surgery. Performed at Princeton Radiology's Minimally Invasive Care Center in Monroe Township by interventional radiologist Kenneth R. Tomkovich, MD, the procedure, called cryoablation, uses a small needle and...

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...

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...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

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...

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...
