Liquid Nitrogen as a Hair Solution?

Celebrity hairstylist Savio John Perreira is using cryogenics to treat hair at his Mumbai salon with the Cryo Detox hair treatment by Kerasol. The process includes a step where liquid nitrogen is sprayed on the hair strands. What could go wrong?

28th SCW Connects International Cryogenics Community

107 scientists, researchers and students attended CSA’s 28th Space Cryogenics Workshop held July 18 at the Heritage Hotel and Conference Center in Southbury CT. Attendees had the opportunity to share ideas in the form of back-to-back oral presentations with poster session breaks. The first day began with lectures on upcoming...

Cryogenic Engineers, Researchers Gather for CEC/ICMC 2019

Scientists and engineers gathered in Hartford CT for the 2019 CEC/ICMC conference. Held in the Connecticut Convention Center, with plenary sessions in the adjoining Marriot Hotel, CEC/ICMC hosted cryogenic experts and industry leaders sharing information and ideas from July 21-25. The traditional oral and poster sessions were held throughout the...

Maglab Creates World Record Magnetic Field with Mini Magnet, Moves to Perfect Findings

The National High Magnetic Field Laboratory (CSA CSM) at FSU in Tallahassee FL recently introduced a novel magnet half the size of a spent toilet tissue roll that usurped the title of “world’s strongest magnetic field” from the metal titan that had held it for two decades. MagLab scientists and...

Experimental Mini-Accelerator Achieves New World Energy Record

Scientists at DESY in Hamburg have achieved a new world record for an experimental type of miniature particle accelerator. For the first time, a terahertz-powered accelerator has more than doubled the energy of the injected electrons. At the same time, the setup significantly improved the electron beam quality compared to...

World’s Smallest MRI Reveals Magnetic Field of Single Atoms

Researchers at the Center for Quantum Nanoscience within the Institute for Basic Science at Ewha Woman’s University in Korea recently made a major scientific breakthrough by performing the world’s smallest magnetic resonance imaging. In an international collaboration with colleagues from the US, QNS scientists used their new technique to visualize...

Latest in Defining Cryogenics

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...

Air Separation and Liquefaction

by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. 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...
