Cryogenics at FAIR Unleashes the Power of Discovery

The Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, is embarking on a pioneering mission that will transform accelerator research and expand our understanding of the universe. With its ambitious vision to explore an extensive research canvas, FAIR is set to become a global hub for scientific exploration,...

Adult Corals Have Been Safely Frozen and Revived for the First Time

Like something out of science fiction, small colonies of mature corals have been safely frozen and revived for the first time, though more work will be needed to ensure their long-term survival, researchers report reported in Nature Communications. Freezing chunks of living corals for safekeeping — or cryopreserving them —...

Cryogenic Prober Determines Quality of Qubit Devices

Germany’s first cryogenic measuring setup for the statistical quality measurement of qubit devices on 200- and 300-mm wafers has commenced operation at Fraunhofer IAF. With the newly established cryogenic on-wafer prober, researchers at the Fraunhofer Institute for Applied Solid State Physics IAF aim to gain a deeper understanding of the...

GKN, Marshall and Parker to Cooperate on Hydrogen Flight

Aerospace industry supplier GKN Aerospace is joining forces with Marshall and Parker Aerospace to explore liquid hydrogen fuel systems for aircraft. The partners plan to develop a liquid hydrogen system suitable for both fuel cell and internal combustion engine aircraft. The planned collaboration will benefit from the UK government-funded H2GEAR...

Unveiling the Intricate Protein Complex Guiding Signaling to Cilia

Cilia, the tiny hair-like projections found on the surface of most eukaryotic cells, act as the conduits for a myriad of signaling processes that orchestrate cellular activities. However, these intricate organelles are not equipped to craft the signaling proteins themselves. Instead, they rely on an intricate network of transport mechanisms...

Electrifying Space: Zenno’s fuel-free satellite pointing system

New Zealand-based space-flight systems company, Zenno Astronautics (Zenno), has proudly announced a remarkable achievement—surpassing a staggering $75 million in product sales (equivalent to USD 48 million) for its groundbreaking innovation, the Z01™ superconducting magnetorquer for spacecraft attitude control. At the heart of Zenno’s success is the Z01, a revolutionary satellite...

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

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...

Approximating pressure changes over time in cryogenic cylinders

I am an Air Resources Engineer with the California Air Resources Board (CARB). My senior management has asked me to investigate approximating pressure changes over time in cryogenic cylinders that contain LNG. So far, I have taken a stab at the problem, seeking to take a back-of-the-envelope approach (as directed...
