Future bright for mini synchrotrons

Colliding a stream of electrons with laser light near an array of tiny silver structures could be the recipe for a new X-ray source that could revolutionize medical imaging and security scanning.

Chemicals induce dipoles to damp plasmons

The light scattered by plasmonic nanoparticles is useful, but some of it gets lost at the surface and scientists are now starting to figure out why.

Light triggers gold in unexpected way

Rice University researchers have discovered a fundamentally different form of light-matter interaction in their experiments with gold nanoparticles.

Army research lights the way for new materials

What happens when gold and silver just don't cut it anymore? You turn to metallic alloys, which are what Army researchers are using to develop new designer materials with a broad range of capabilities for our Soldiers.

Robot bloodhound tracks odors on the ground

Bloodhounds are famous for their ability to track scents over great distances. Now researchers have developed a modern-day bloodhound—a robot that can rapidly detect odors from sources on the ground, such as footprints. ...

Researchers squeeze light into nanoscale devices and circuits

As electronic devices and circuits shrink into the nanoscale, the ability to transfer data on a chip, at low power with little energy loss, is becoming a critical challenge. Over the past decade, squeezing light into tiny ...
