Tempshield Publishes “How to Care for Cryogenic Gloves and PPE in Age of Infection”

Whether mitigating the risk of COVID-19, Norovirus or the common flu, it’s vital that researchers and other front-line workers can avoid infection while doing their jobs. As such, proper care and cleaning of cryogenic gloves, cryogenic protection, face shields and other personal protective equipment (PPE) cannot be overlooked. Tempshield (CSA...

FDA Clears ‘World’s First’ Portable, Low Cost MRI following Positive Clinical Research

The US Food and Drug Administration has provided clearance to the “world’s first” bedside MRI system. Connecticut-based Hyperfine said it will begin shipping its portable, low field modalities this summer. The machine’s 510(k) FDA clearance was granted as Yale researchers reported accurate and safe results from tests involving brain readings...

Linde Cryogenics Supplies First of Kind Helium Recovery System to Sumitomo Cryogenics

In late March, Linde Cryogenics (CSA CSM) delivered a modular helium recovery system to Sumitomo Cryogenics of America, Inc's (CSA CSM) Allentown PA production facility. By capturing and recycling helium from production operations, the system is expected to reduce consumption of purchased helium at the facility by 70%. The system...

SLAC Researchers Use Cryo-EM to Discover Giant Cavity in Key Tuberculosis Molecule

Researchers from the Department of Energy’s SLAC National Accelerator Laboratory using Cryo-EM technology have discovered a strange new feature of a protein that’s thought to be important in the treatment of tuberculosis. The protein contains a highly unusual “huge” interior pocket that appears capable of passing a wide range of...

Champaign-Urbana MTD Purchases Two Hydrogen Buses

The Champaign-Urbana Illinois Mass Transit District (MTD), has ordered two hydrogen fuel cell buses from New Flyer of America. The contract calls for New Flyer to supply two hydrogen fuel cell electric sixty-foot Xcelsior CHARGE H2™ heavy duty transit buses in the Champaign, Urbana and Savoy regions of the state....

Infertile Cancer Survivor Gives Birth Using Frozen, Lab-Matured Egg in Scientific ‘Breakthrough’

In a world first, a French woman has given birth after freezing, thawing and fertilizing her immature eggs in a procedure called in vitro maturation, according to a study published in the journal Annals of Oncology. Doctors say this development "is particularly important for cancer patients, but it’s also a...

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

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...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
