Low-cost printable photonic integrated devices
By directly printing devices onto a functional resist with a high refractive index, optical components can be created without the use of any etching steps. This new low-cost fabrication technique can produce printable integrated circuits, as reported by researchers at aBeam Technologies, the Molecular Foundry and NanoOptic Devices. Presenting in Nanotechnology, several optical components are demonstrated, including ridge waveguides, light splitters and digital planar holograms that operate in the visible wavelength range. The approach could revolutionize the development of integrated photonic devices.

Origami Robot Can Self-Assemble and Walk Without Human Help
A research team at Harvard and MIT announced today that they’ve created a self-assembling robot. The machine, which begins as a flat sheet of material, exploits principles of origami to fold itself into a 3-D robot capable of walking without any human assistance.

Small Size Enhances Charge Transfer in Quantum Dots
In a study just published in the journal Chemical Communications, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory, Stony Brook University, and Syracuse University show that shrinking the core of a quantum dot can enhance the ability of a surrounding polymer to extract electric charges generated in the dot by the absorption of light.

UNIST research team opens graphene band-gap
Ulsan National Institute of Science and Technology (UNIST) announced a method for the mass production of boron/nitrogen co-doped graphene nanoplatelets, which led to the fabrication of a graphene-based field-effect transistor (FET) with semiconducting nature. This opens up opportunities for practical use in electronic devices.
