Understanding the Origin of Matter with the CUORE Experiment

The Cryogenic Underground Observatory for Rare Events (CUORE) can search for these rare NLDBD processes using different nuclei. Scientists rely on complementarity among searches using different nuclei to have a better understanding of the underlying physics in the process. Complementarity in physics involves theories that contrast with each other but...

How the SpaceX Explosion Would Have Been Different in Florida

Shortly after SpaceX’s massive Starship launched from Texas on its first full test early Thursday, the 400-foot stack of hardware began to tumble until it broke apart in a fiery explosion over the Gulf of Mexico. The overall demonstration mission – a test of the new rocket’s ability to ignite and clear the pad’s 500-foot tower...

Svanehøj Acquires Complete Cryogenic Services

With its third company acquisition in just over two years, marine pump specialist, Svanehøj, continues to expand its service solution business, this time by taking over California-based Complete Cryogenic Services (CCS), a specialist in service and overhaul of submerged pumps on LNG tankers. The number of LNG tankers globally has grown...

Skyroot Aerospace and Dhawan-II’s More Powerful 3D-Printed Cryogenic Engine

In 2020, the world was introduced to Dhawan-I, a 3D printed cryogenic engine made by Skyroot Aerospace. Three years later, the Indian company has been working on a more powerful model, unveiling to the public the new and improved Dhawan-II, which is said to have successfully completed testing. Like its predecessor,...

A Game Changer for CERN

CERN’s new visitor and education center, Science Gateway, due to open this autumn, will welcome up to half a million people each year. Project leader Patrick Geeraert describes how this iconic project came about, how it will operate, and what it aims to achieve. How did the idea for Science...

New SLAC-Stanford Battery Center Targets Energy Transition

The Department of Energy’s SLAC National Accelerator Laboratory and Stanford University announced the launch of a new joint battery center at SLAC. It will bring together the resources and expertise of the national lab, the university and Silicon Valley to accelerate the deployment of batteries and other energy storage solutions...

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...
