Templated growth technique produces graphene nanoribbons with metallic properties

A new 'templated growth' technique for fabricating nanoribbons of epitaxial graphene has produced structures just 15 to 40 nanometers wide that conduct current with almost no resistance. These structures could address the challenge of connecting graphene devices made with conventional architectures - and set the stage for a new generation of devices that take advantage of the quantum properties of electrons.

Seeing in stereo: Engineers invent lens for 3-D microscope

Engineers at Ohio State University have invented a lens that enables microscopic objects to be seen from nine different angles at once to create a 3D image. Other 3D microscopes use multiple lenses or cameras that move around an object; the new lens is the first single, stationary lens to create microscopic 3D images by itself.

Engineers make breakthrough in ultra-sensitive sensor technology

Princeton researchers have invented an extremely sensitive sensor that opens up new ways to detect a wide range of substances, from tell-tale signs of cancer to hidden explosives. The sensor, which is the most sensitive of its kind to date, relies on a completely new architecture and fabrication technique.

Light harvesting offers new vision

Bounce light around in a small enough space and you can magnify its intensity a thousand-fold, maybe more. The secret, says Professor Saulius Juodkazis, is having the right 'landscape' for the lightwaves to bounce around in. This is the principle behind Professor Juodkazis's research, which aims to develop the next generation of super sensors. It's something like catching dust motes in a beam of sunlight, shrunk down to nanoscale and magnified many times over.

Sound makes nanowires blink

When made from semiconductors these nanowires not only transport electric current along their axis but also can very efficiently emit light. Researchers have now combined these two fundamental properties.

Nanotechnology: Engines On

Controlling climate change, abandoning dependency on fossil fuels, and creating the conditions for sustainable development will require as great a transformation as our ancestors accomplished over tens of thousands of years in moving from agrarian to urban societies. "Nanotechnology: Engines On" is a new book about how Nanotechnology is contributing to solve this vital challenges.
