New Way To Make Sheets Of Graphene Discovered

Graphene's promise as a material for new kinds of electronic devices, among other uses, has led researchers around the world to study the material in search of new applications. But one of the biggest limitations to wider use of the strong, lightweight, highly conductive material has been the hurdle of fabrication on an industrial scale.

Power for Extreme Environments

Specifying the ideal power management solution for remote wireless devices found in extreme environments and hard-to-access locations requires more ruggedized solutions. Fortunately, two viable options are now available: lithium thionyl chloride (LiSOCL2) chemistry that can operate for 40+ years, and energy harvesting devices coupled with special rechargeable lithium-ion batteries designed for extreme environments that can deliver up to 20+ years of battery life. Lithium thionyl chloride chemistry is proven for use in extreme environments.

Mars Technologies Spawn Durable Wind Turbines

A technology built for Mars supports the demand for clean energy on Earth. In the early 1990s, NASA was planning for an extended stay on Mars, and scientists at Ames Research Center were concentrating efforts on creating a complete ecological system to sustain human crew-members during their time on the Red Planet. The group started looking at maximizing energy efficiency and alternative methods to make power on a planet that is millions of miles from Earth. They turned to a hybrid concept combining two renewable sources: wind and solar power technologies. Large surface temperature swings on Mars produce windy conditions; extreme examples are the frequent dust storms that can block nearly all sunlight.

Big Ideas for Small Spaces

Over 24 hours from April 4 to 5, six top French design studios conceived and presented new product concepts for urban environments during the Small Spaces Design Hackathon, presented by Cut&Paste in partnership with Hewlett-Packard. In dense city neighborhoods, homes are small and office space is at a premium, so urban dwellers must be more creative in how they use their space. The design concepts were presented at Cyclone Le Studio as part of ZED, HP’s creative popup space.

Aircraft Engine Coating Could Triple Service Life and Save Fuel

Researchers at University West in Sweden are using nanoparticles in the heat-insulating surface layer that protects aircraft engines from heat. In tests, this increased the service life of the coating by 300%. The hope is that motors with the new layers will be in production within two years. The surface layer is sprayed on top of the metal components. Thanks to this extra layer, the engine is shielded from heat. The temperature can also be raised, which leads to increased efficiency, reduced emissions, and decreased fuel consumption.

Switchable Material Absorbs and Stores Sun's Energy

A team at MIT and Harvard University has created a material that absorbs the sun’s heat and stores that energy in chemical form, ready to be released again on demand.The technology provides an opportunity for the expansion of solar power into new realms, specifically applications where heat is the desired output.“It could change the game, since it makes the sun’s energy, in the form of heat, storable and distributable,” says Jeffrey Grossman, the Carl Richard Soderberg Associate Professor of Power Engineering at MIT.SourceAlso: See other Materials tech briefs.
