Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

Russian Physicists Obtain Data on Particle Self-organization in Ultracold Dusty Plasma

Physicists in Russia recently investigated the behavior of particles in dusty plasma at a temperature below 2 K, an experiment that revealed nanoclusters forming in the plasma and the synthesis of polymer fibers taking place at extremely low temperatures. According to the team, such results can be used to create...

Electron Camera at SLAC Films High-speed Molecular Movie

Researchers using an extremely fast electron camera at the Department of Energy’s SLAC National Accelerator Laboratory have made the first high-definition “movie” of ring-shaped molecules breaking open in response to light.

Cryo-EM Reveals Crucial Electrical Switch in Brain

Scientists using cryo-EM have revealed the structure of a critical receptor (AMPA) in the brain associated with learning, memory, behavior and mood. The research was also the first to reveal the structure of AMPA receptors in a natural state, a discovery that could lead to new insight about the mechanism...

Researchers Discover Water that Never Freezes

Can water reach -263°C without turning into ice? The answer is yes, according to a group of physicists and chemists from ETH Zurich and the University of Zurich who identified an unusual way to not only prevent water from forming ice crystals while at extreme sub-zero temperatures but to also...

Working Together as a “virtual telescope,” Observatories Around the World Produce First Direct Images of a Black Hole

MIT News reported on April 10 that an international team of over 200 astronomers had captured the first direct images of a black hole. They accomplished this remarkable feat by coordinating the power of nine major radio observatories on four continents, to work together as a virtual, Earth-sized telescope. In...

Turning Patient Cells into Cancer Fighters

Cancer therapy could soon include a personalized cancer treatment based on engineered immune cells derived from a patient's individual cells. The approach involves attaching proteins to these cells, receptors that target antigens present in cancer cells to then enable a patient’s immune system to seek out and destroy tumors.

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...
