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...

This addition strengthens the program’s ecosystem of quantum computing hardware, software, and service providers who build and offer integral components of functional quantum computing systems. The Novera QPU Partner Program, launched...

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...

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...

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...

Data on thermal expansion down to 40K

For our cold mechanics, we use ball bearings from ADR from stainless steel which is AISI 440C, DIN X105CrMo17, W.Nr. 1.4125. Does anyone know the data of thermal expansion of this material down to 40 K?

Difference between radar and servo gauge for LNG tanks?

What is the difference between radar and servo gauge for LNG tanks? How do I understand the gauging system for LNG tanks and choose the best one?

Materials for "cryogenics in spacetech"?

I had to take a seminar in a national competition that is to be held in our country on the topic “cryogenics in spacetech.” For this, I need some materials related to it, and I thought to approach you for help. Can you suggest some relevant materials?

Information on how the emissivity of the panel changes with air fouling?

I work at a facility with a large thermal vacuum chamber. We are using both nitrogen and helium shrouds.
