Silver nanoparticles take spectroscopy to new dimension

A new way of organizing nanostructures has boosted Raman signals by a hundred thousand times to better identify and characterize different molecules.

Tweaking quantum dots powers-up double-pane solar windows

Engineered quantum dots could bring down the cost of solar electricity.

Sensor the size of a nitrogen atom investigates hard drives

Researchers have developed a quantum sensor that will be able to precisely measure the tiny magnetic fields we can expect to see in the next generation of hard discs. The sensor itself is just slightly larger than a nitrogen atom, with a synthetic diamond to act as a substrate.

Single metalens focuses all colors of the rainbow in one point

Lens opens new possibilities in virtual and augmented reality.

Carbon nanotube as ultrafast emitter with narrow energy spread at optical frequency

Scientists have successfully demonstrated exciting findings on the realization of field-driven ultrafast photo electron emission, in a system capable of much higher phase synchronization than its photon-driven counterpart.
