Nanoparticles Shown to Improve Hydrogen Storage

Sometimes you have to go small to win big. And that's just the approach an interdisciplinary and multi-lab research group took in using nanoparticles and a novel nanoconfinement system to develop a method to change hydrogen storage properties. The team's discovery could enable the creation of high-capacity hydrogen storage materials...

ITER’s Promise of Clean Energy

At a dusty construction site amid the limestone ridges of Provence, workers scurry around immense slabs of concrete arranged in a ring like a modern-day Stonehenge. It looks like the beginnings of a large commercial power plant, but it is not. The project, called ITER, is an enormous, and enormously...

Sumitomo Cryogenics of America Acquires Ferran Technology

Sumitomo (SHI) Cryogenics of America, Inc. (SCAI) (CSA CSM), has announced its acquisition of Ferran Technology Inc., a leading-edge provider of vacuum measurement and control instrumentation to the micro-electronics manufacturing industries, as well as scientific research and industrial vacuum markets.

Electro-optical Switch Transmits Data at Record-Low Temperatures

A silicon optical switch developed at Sandia National Laboratories is the first to transmit up to 10 gigabits per second of data at temperatures just a few degrees above absolute zero. The device, according to researchers there, could enable data transmission for next-generation superconducting computers that store and process data...

MRI Scans Help Spot HIV in the Brain

Scientists at University College London have developed a way to use MRI scans to help identify when HIV is persisting in the brain despite effective drug treatment. The team looked at data from 146 HIV patients who were investigated for cognitive problems between 2011 and 2015. There was evidence that...

Liquid or Gas, DUNE Researchers Weigh Transport of Detector’s Argon

Nearly a mile below the surface of South Dakota, scientists are preparing the Deep Underground Neutrino Experiment, or DUNE, a physics experiment that will look at minuscule particles called neutrinos. A beam of neutrinos will travel 800 miles through the Earth from Fermi National Accelerator Laboratory (CSA CSM) to the...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...

Seeking recommendations for commercial sensors

I would like to measure vibrations in small LHe cryostats. Could anybody recommend commercial sensors which would be suitable for the purpose? I am interested in the frequency range between 1Hz and a couple of KHz, with particular attention to the low frequency side.

Estimating cost of carbon steel, pure helium storage tanks

In order to perform an indicative cost assessment of our helium cryogenic plant (still in the design phase), I need an estimation of the cost of carbon steel room temperature pure helium storage tanks. The storage pressure is 20 bar. Can anyone give me suggestions about how to estimate the...

Supplier of pressure sensor that works down to 4.2 K

In an actual experiment we would like to measure the static pressure in a cryostat in the range between one and four bar. Therefore we are looking for some (more or less) cheap pressure sensors that work in liquid helium in the pressure range up to five bar. Unfortunately all...

Looking for reference/textbook suggestions

Can you suggest some reference textbooks for practical thermodynamics applications in cryogenic fields? I need textbooks with cryogenics calculations and examples, dimensioning procedures, second principle applications in cryogenics, heat load calculations, cryogenic pump application, etc. Do such books exist? Does any similar source of information exist?
