Scientists Produce First In-Vitro Lion Embryos

A team of scientists have succeeded in producing the very first African lion in-vitro embryos after the vitrification of immature oocytes. For this specific method of cryopreservation, the scientists, who hail from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in Germany, Givskud Zoo–Zootopia in Denmark, and the University of Milan,...

Researchers Reveal Electronic Nature of Charge Density Wave and Electron-Phonon Coupling In Kagome Superconductor

Recently, the Kagome superconductors AV3Sb5 (A = K, Rb and Cs) have attracted enormous attention due to their novel phenomena and rich physics. They exhibit unconventional charge density wave (CDW), giant anomalous Hall effect, and superconductivity. The CDW state is intimately related to the anomalous Hall effect and competes with superconductivity...

Demaco Releases New Range of Cryogenic Valves

Valve manufacturer Demaco Netherlands BV (Demaco) has announced the release of its new range of Demaco Cryogenic Valves. Having redesigned and improved its current valve range, which includes manual on/off, pneumatic on/off, and control valves, the company has overhauled its technology to help increase the area of usage. The new valves...

Boeing Achieves Major Advance in Using Composites for Cryogenic Fuel Tanks

Boeing has announced a technology breakthrough for cryogenic fuel tanks. These tanks are essential components of liquid-fueled rockets because they hold the liquid hydrogen and the liquid oxygen that act as the fuel. They could also play a very important role in the development of long-haul, zero-emission flight, carrying liquid hydrogen as jet engine...

#BlackInQuantum

Black scientists have played important roles in the history of quantum physics. In this growing area of specialization, there’s an opportunity to continue that legacy. The sixth person to earn a doctoral degree in physics from an American institution was African American scientist Edward Alexander Bouchet; it was 1876, just 11...

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

You are encouraged to read Cryo Central’s History...

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...

Seeking technical publication that explains the science behind the cryogenic treatment of aluminum

Would you know of a technical publication that would list the benefits and explain the science behind the cryogenic treatment of aluminum, specifically a 356-T6 aluminum cylinder head casting? Eddie Phillips

Source of emissivity data for aluminum and aluminized Mylar at room temperature, 77K and 4.2K

Can anyone recommend a source of emissivity data for aluminum and aluminized Mylar at room temperature, 77K and 4.2K? Also, I would be interested in finding a facility that can measure this information. Any information will be greatly appreciated. William Einziger, GE Healthcare

Looking to purchase new LN2 freezer: any suggestions?

I will be purchasing a new liquid nitrogen freezer soon, but I am limited by space restrictions. The freezer cannot be more than 38 inches wide. However, it would be beneficial if the freezer holds a high number of racks such as 24. In addition, we prefer not to purchase...

Affordable flow meter to measure LN2 flow through a pipeline

I am trying to find out if anyone knows of or has used an affordable flow meter that can measure liquid nitrogen flow through a pipeline. It doesn’t need to be very accurate as it’s really to allow people in different departments to allocate cost rather than for scientific measurement....
