Study Points Way to More Efficient Liquid Hydrogen Tanks

by Tina Hilding, Voiland College of Engineering and Architecture, Washington State University Washington State University researchers have developed a mathematical model and a set of recommendations to improve liquid hydrogen storage tank operations that could someday make hydrogen a more viable alternative for powering vehicles and other industrial processes. The...

Stanford Finds Crystal That Could Revolutionize Quantum Tech

Superconductivity and quantum computing have rapidly evolved from theoretical frontiers to real-world technologies. The 2025 Nobel Prize in Physics recognized breakthroughs in superconducting quantum circuits that promise ultra-powerful computing systems. Yet these technologies demand cryogenic operating conditions, near absolute zero, where most materials lose their useful properties. Identifying materials that...

VALCOR ENGINEERING ADDS NEW VIBRATION LABORATORY

Valcor Engineering Corporation, a longtime designer and manufacturer of precision fluid and motion control components—including cryogenic solenoid valves—has expanded its in-house testing resources with the addition of a new Vibration Laboratory at its Springfield, New Jersey headquarters. The new facility provides full 3-axis (X, Y, Z) vibration testing, including sine...

Delta Reliably Meets the Need for Cryogenic Pipe Shoes in the LNG Space

As the LNG industry has grown, so has the number of suppliers who serve that market. No one knows that better, perhaps, than Delta Machine & Ironworks. The Baton Rouge-based fabricator is rapidly becoming the “go to” supplier of one of the most indisputably vital support products on LNG jobsites. Over...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

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.

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...
