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...

Cryogenic Electronics

Randall Kirschman, consulting physicist, Mountain View, California ExtElect@gmail.com Cryogenic electronics—the operation of electronic devices, circuits, and systems at cryogenic temperatures—has been a valuable technology for decades. Cryogenic electronics (also referred to as low-temperature electronics, or cold electronics) can be based on semiconductive devices, on superconductive devices, or on a combination...

Particle Physics: High Energy Physics

Cryogenics and High-Energy Physics 1. From symmetry magazine: http://www.symmetrymagazine.org/cms/?pid=1000627: Cryogenics is the study of how materials behave at temperatures near absolute zero. In high-energy particle accelerators, such frigid temperatures reduce the electrical resistance of wires in superconducting magnets, increasing the magnet strength and allowing faster particle acceleration. The same holds...

HTS Degaussing Systems

From the Spring 2009 issue of Cold Facts (Volume 25, Number 2): Thanks to a joint project by the US Navy and a number of industry partners, high temperature superconducting (HTS) technology is now at the heart of an advanced degaussing system aboard the USS Higgins at the naval station...

Magnetic Resonance Imaging

From http://www.superconductors.org: An area where superconductors can perform a life-saving function is in the field of biomagnetism. Doctors need a non-invasive means of determining what’s going on inside the human body. By impinging a strong superconductor-derived magnetic field into the body, hydrogen atoms that exist in the body’s water and...
