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...

World-First in Oman

A momentous event unfolded as the world’s first-ever liquefied hydrogen carrier, Suiso Frontier, graced the shores of Sultan Qaboos Port in Muscat on August 14. Proudly crafted by the renowned Kawasaki Heavy Industries (KHI), this marks the long-anticipated debut of Suiso Frontier in the Sultanate of Oman. The name “Suiso”...

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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...

Presence of alloying elements in tool steels

I want to expand my knowledge of cryogenics in general and tool steels in particular. Specifically, I am keenly interested in learning about the presence of alloying elements in tool steels and how their presence in various combinations affects the performance of tool steels after cryogenic treatment.

Pros and cons of barcoding samples

I was wondering if I could ask for input on pros and cons of barcoding. We are in the process of trying to decide if we should start barcoding our samples and I’m just not sure if this is feasible for our organization. We have numerous sites all over the...
