Improving LED Screens with Scotch Tape and Laser Beams

Researchers at the Ultrafast Laser Lab at the University of Kansas have created a new bilayer material that someday could lead to more efficient and versatile light emission. Each layer, formed by combining atomically thin layers of molybdenum disulfide and rhenium disulfide, measures less than one nanometer in thickness.

New Report Details Communication Best Practices for Science Labs and Facilities

The InterAction Collaboration, a group of science communicators from 18 laboratories and institutions from 11 countries, has issued a new report summarizing communication best practices. It covers more than a dozen categories of communication and outreach activities, including managing reputational risks through communications, strategic approaches to communications and outreach, traditional...

ISRO Successfully Tests the GSLV MkIII Cryogenic Upper Stage

The Indian Space Research Organization (ISRO) completed a flight duration test for the cryogenic upper stage of its GSLV MkIII in mid-February. The move marked a significant milestone, according to ISRO, as the 640-second test was the last in series of engine and stage development hot tests before the launch...

Industry Team Developing High-Efficiency Hydrogen Compressor

Sustainable Innovations, Inc., Greenway Energy and Savannah River National Laboratory have announced a partnership designed to maximize the benefits of two cutting edge hydrogen compressor technologies by combining them into one hybrid compressor with both high reliability and efficiency.

Highview Expands LAES Offerings in NYC

Highview Power Storage, a designer and developer of large-scale energy storage solutions for utility and distributed power systems, has agreed to enter ACRE, New York City’s business incubator for smart cities, smart grid and clean energy at the Urban Future Lab (UFL) located at the NYU Tandon School of Engineering.

ITER Completes Niobium-Tin Procurement

The ITER community is celebrating a significant milestone: the end of a nine-year campaign to procure 88 km of niobium-tin superconductor for ITER's toroidal field coils. The total represents some 825 tons of material with an estimated market value of 350 million euros. Six ITER Members—China, Europe, Japan, Korea, Russia...

Dilution Refrigerators

Dilution refrigerators are a common technique for reaching temperatures below 1K, particularly where continuous cooling at these temperatures is required. Helium exists in two stable isotopes: 4He and 3He. Naturally occurring 3He is extremely rare, constituting less than 1 part per million of helium gas. However, 3He can be manufactured,...

Oxygen Deficiency Hazards

Oxygen Deficiency Hazards (ODH) are a significant safety issue in cryogenic facilities. ODH occurs when inert gases such as nitrogen, helium or argon displace room air and thus lower the percentage of oxygen in the space below that required for human life. OSHA defines an area as oxygen deficient if...

Kelvin Temperature Scale

The Kelvin temperature scale is the principal temperature scale used in cryogenics and science. The kelvin is also one of the seven base units in the Système International d’Unités (SI) and is the unit of thermodynamic temperature. Thermodynamic temperature is a fundamental physical quantity (like mass, length or electrical current)...

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...

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...

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...
