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...

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...

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

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...

Suppliers of regenerator materials

I was looking for suppliers of regenerator materials. Can you please provide a list of vendors for: • Lead spheres • Bronze screen discs • Rare earth materials and spheres Thank you in advance for any help you can provide.

Containing ice accumulation while recovering helium

We are implementing a system to recover helium from our Janis ST-500 continuous flow LHe cryostat. The recovery system uses standard 1/4″ plastic tubing, which we connect directly to the cryostat’s exhaust port. The problem with this setup is that the gas is still quite cold as it leaves the...
