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...

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...

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
