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...

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...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

Wind Tunnels

Dr. Robert Kilgore The development of the cryogenic wind tunnel is one of many significant breakthroughs in both cryogenics and wind-tunnel technology made during the past millennium. Interest in the development of high-speed commercial and military aircraft resulted in a review of problems of flow simulation in transonic wind tunnels...

History of Cryogenics

From the Fall 1999 issue of Cold Facts magazine Millennium Breakthroughs A variety of CSA members give different perspectives on the past millennium: What were the most significant breakthroughs in cryogenics during the past millennium? Prof. R.G. Scurlock, Kryos Technology, scurlock@soton.ac.uk (“Breakthrough” = way through obstacles — Oxford English Dictionary)...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
