Just as a chameleon changes its color to blend in with its environment, Duke University engineers have demonstrated for the first time that they can alter the texture of plastics on demand, for example, switching back and forth between a rough surface and a smooth one.

The technique makes use of plasmonic excitation in nanocavities. In a demonstration, a rectangular nanocavity was used to detect the presence of 22nm beads. This approach may open new routes to create optical tweezers at the nanoscale, for ultra-accurate sensing, trapping, and arranging of nanoscale objects, such as biomolecules.

Imec has successfully fabricated crystalline silicon solar cells including 2D periodic photonic nanostructures made with nano-imprint lithography. The result was an improvement in energy-conversion efficiency, compared to unpatterned cells, through a better absorption of the light spectrum. The technique shows a path to further reducing the thickness of solar cells while keeping the efficiency as high as possible.

Hydrogen fuel cells, like those found in some "green" vehicles, have a lot of promise as an alternative fuel source, but making them practical on a large scale requires them to be more efficient and cost effective. A research team from the University of Central Florida may have found a way around both hurdles.

Scientists have come up with a novel process for manufacturing transistors that combine flexibility and electron mobility and are capable of working at very high frequencies in the GHz range. The process uses a form of graphene in solution that is compatible with printing techniques. Electronic components such as these should lead to the development of high-performance electronic circuits built into everyday objects.
