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.

Researchers Use Sun to Produce Solar-Energy Materials

In a recent advance in solar energy, researchers have discovered a way to tap the sun not only as a source of power, but also to directly produce solar energy materials.This breakthrough by chemical engineers at Oregon State University could soon reduce the cost of solar energy, speed production processes, use environmentally benign materials, and make the sun a “one-stop shop” that produces both the materials for solar devices and the energy to power them.The work is based on the use of a “continuous flow” microreactor to produce nanoparticle inks that make solar cells by printing. In this process, simulated sunlight is focused on the solar microreactor to rapidly heat it, while allowing precise control of temperature to aid the quality of the finished product. The light in these experiments was produced artificially, but the process could be done with direct sunlight, and at a fraction of the cost of current approaches.SourceAlso: Read other Materials tech briefs.

Using Lightning to Measure Health of Power Grids

When power switches or lightning create high voltage currents, power companies view it as a problem. These so-called natural transients have the power to destroy components and cause disturbances along the transmission line.

Can Cobalt-Graphene Beat Out Platinum As Catalyst in Hydrogen Fuel Cells?

Platinum works well as a catalyst in hydrogen fuel cells, but it is expensive and degrades over time. Brown University chemist Shouheng Sun and his students have developed a new material — a graphene sheet covered by cobalt and cobalt-oxide nanoparticles — that can catalyze the oxygen reduction reaction nearly as well as platinum does and is substantially more durable.

'Nanoflowers' for Energy Storage and Solar Cells

North Carolina State University researchers have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface area. The GeS flowers hold promise for next-generation energy storage devices and solar cells.
