Nanoshells: Potential catalysts and cradles of life (w/video)

A way to coax simple, inorganic nanoparticles to spontaneously assemble into shells has been discovered, potentially paving the way for more efficient industrial chemical processing, gene delivery and clean-up of chemical contaminants in the environment, researchers say. And it explores how life may have started.

On-chip observation of THz graphene plasmons

Researchers developed a technique for imaging THz photocurrents with nanoscale resolution, and applied it to visualize strongly compressed THz waves (plasmons) in a graphene photodetector. The extremely short wavelengths and highly concentrated fields of these plasmons open new venues for the development of miniaturized optoelectronic THz devices.
