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.

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...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

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...
