How Hydrogen Fuel Cells and Combustion Could Revolutionize Racing

Hydrogen power is gradually making its mark on the motorsport scene. This year, we have already witnessed hydrogen race cars competing in the Fuji 24 Hours, hillclimbs, and the Dakar Rally. Looking ahead to 2025, the world’s first hydrogen championship, Extreme H, will debut, and by 2027, hydrogen prototypes are...

En Route Toward the First German Quantum Computer

Fraunhofer IPMS is collaborating on the development of an integrated German quantum computer based on superconducting quantum chips. Together with 24 German research institutions and companies, under the coordination of Forschungszentrum (FZ) Jülich, Fraunhofer IPMS is working on this quantum computer with the goal of improving error rates. At the halfway...

Lightweight Supramolecular Material for Compressed Hydrogen Storage

A team of chemists from the University of Hong Kong, Northwestern University, and Duke University has developed a supramolecular material capable of compressing hydrogen for storage without being too heavy. Their study, published in Nature Chemistry, demonstrates the use of porous organic crystals for hydrogen storage. Hydrogen has long been...

Indian Student to Research Liquid Hydrogen with Monash University

A Ph.D. student from India is conducting groundbreaking research with Monash University’s Department of Civil Engineering after being selected as the recipient of the prestigious Australian government-funded Maitri Scholars Program. Chennai native Rohith Prakash will focus on advancing the safe transport and storage of liquid hydrogen, with a particular emphasis on...

Rising Helium Demand Set to Double by 2035

A new report from IDTechEx suggests that global helium demand is set to double by 2035, driven by the wide-ranging applications of this vital element. Helium, a finite yet critical resource, is indispensable across multiple industries. From medical imaging to semiconductor manufacturing, helium’s unique properties—such as high thermal conductivity, chemical...

Cryogenic Therapy Puts the Freeze on Esophageal Cancer

Patients with esophageal tumors often experience malignant dysphagia, or difficulty swallowing due to an obstruction, complicating their treatment and preventing them from eating normally. The Advanced Center for Therapeutic Endoscopy at WVU Medicine J.W. Ruby Memorial Hospital is the first in West Virginia to offer an innovative solution to this...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

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?

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?
