Special Permit Sought for Cryogenic Ethane Transport Via Rail
Gas Innovations LNG Refrigerants Inc. is seeking authorization to transport cryogenic ethane via rail in DOT-113C120W9 and DOT-113C120W tank cars, according to the Pipeline and Hazardous Materials Safety Administration (PHMSA). PHMSA, in consultation with the Federal Railroad Administration (FRA), is handling review of the special permit application and requesting comments...
Cryogenic CMOS Design for Quantum Chips on 22FDX
Semiwise in Glasgow has developed transistor SPICE models for cryogenic CMOS chip design and verification using the GlobalFoundries (GF) 22FDX 22nm fully depleted silicon-on-insulator (FD-SOI) process technology. The technology can be used for chips for quantum computers and also for data center processors with liquid nitrogen cooling. Semiwise used its patented...

In this exclusive SelectScience® interview, we speak with a panel of scientific experts to find out how cryogenic storage is helping to advance their novel research projects and break scientific boundaries. Our panel of experts include Dr. Ronan Chaligné, Director of the Single Cell Analysis Innovation Lab at Sloan Kettering Institute,...
CryoEdge Solves an Ancient Problem with a Cutting-Edge Solution
Ever since the Stone Age, people have searched for the most effective ways to cut and shape materials for best use. This quest has most recently resulted in revolutionary breakthroughs and developments like lasers, plasma beams, and water jets as cutting instruments. Despite these advances, the overwhelming majority of cutting...
How to Avoid a Tank Collapse
The industrial gas industry produces the elemental components of “air” (nitrogen, oxygen, and argon) that are used in other industries as part of their processes. Once separated from air, each element exists as an extremely cold cryogenic temperature liquid. Typical liquid temperatures are −185° C. Large, field-erected tanks are used...

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...
Magnets
From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...
Energy Storage
From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...
Cryocoolers
What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

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?
