GE Healthcare Acquires Cryogenic Cold Chain Specialists

GE Healthcare has acquired Asymptote Limited, a company specializing in cryochain technology for sensitive cellular therapies. The acquisition fills a critical gap in GE Healthcare’s end-to-end ecosystem of products and services for cell therapy production, according to GE, and will be an important piece of a portfolio enabling the industrialization...

A Silver Snoopy for Valcor Top Dog

In a March ceremony, NASA presented Valcor's Yuri Gerasimov with its Silver Snoopy, an award given to candidates who have significantly contributed to the human space flight program. Less than one percent of the aerospace program workforce receives the Silver Snoopy annually, making the award a special honor. Gerasimov played...

New Material Raises Questions About Theoretical Model of Superconductivity

The US Department of Energy’s Ames Laboratory has successfully created the first pure, single-crystal sample of a new iron arsenide superconductor, CaKFe4As4, and studies of this material have called into question some long-standing theoretical models of superconductivity.

The Life of an Accelerator

Tens of thousands of accelerators exist around the world, producing powerful particle beams for the benefit of medical diagnostics, cancer therapy, industrial manufacturing, material analysis, national security and nuclear as well as fundamental particle physics. Particle beams can also be used to produce powerful beams of X-rays.

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...

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...

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

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...
