H2 Storage System Successfully Scaled up

Since September 2023, AMBARtec has been testing its 7.5 kg H2 storage system in full operation with hydrogen. The aim was also to optimise the plant control and find the best system configuration in terms of energy balance. Maximum energy efficiency: AMBARtec’s storage system + SOECThe energy balance analysis shows...

Saving Florida’s Blighted Corals

Florida’s coral reefs are critical to the state’s economy. They protect beaches and play a vital role in supporting thriving fisheries. However, time may be running out to witness some types of live coral in the Florida Keys. A severe heat wave in the summer of 2023 killed many species, and...

CEC to Award Two Prestigious Scholarships at 2025 Conference

The Cryogenic Engineering Conference (CEC) will award two distinguished scholarships at the upcoming 2025 CEC/ICMC: the Donna Jung Memorial Scholarship Award and the Klaus and Jean Timmerhaus Scholarship Award. These awards are part of the CEC’s ongoing efforts to encourage the next generation of engineers and scientists in the field...

Beckman Institute Labs Bridge Advanced Imaging and Alzheimer’s Research

The Beckman Institute for Advanced Science and Technology at the University of Illinois Urbana-Champaign has embarked on a life-changing research project to advance the early detection and diagnosis of Alzheimer’s disease. With the support of a $3 million grant from the US National Institute on Aging of the National Institutes...

Bluefors Lab Offers Cryo Measurements, a Low Risk Model for Experiments

Quantum technology continues to develop at a rapid pace, and the need for access to cryogenic cooling systems for quantum research has never been greater. While established institutions have an increasing number of options to choose from, startups and smaller institutions still face considerable challenges, not least of which are...

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

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...

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...

Looking for some advice regarding cryogenic modeling in ANSYS FEA software

I am looking for some advice regarding cryogenic modeling in ANSYS FEA software. I have been trying to use the Transient Thermal module, in workbench 14.5, to model the cooling of a device in a dilution fridge. I have approximate values for the cooling power of each plate in the...
