Light drives single-molecule nanoroadsters
Scientists are driving three-wheeled, single-molecule 'nanoroadsters' with light and, for the first time, seeing how they move.
'Pressure-welding' nanotubes creates ultrastrong material
A new study demonstrates the possibility of covalent intertube bonding giving rise to interconnected (polymerized) multiwall nanotubes; these nanotubes being cheaper to produce than their single-wall counterparts.
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.
Photosynthesis: Gathering sunshine with the world's smallest antennas
Research on photosynthetic antenna complexes illuminates how they harvest light in plants, algae and bacteria.
Laser particles could provide sharper images of tissues
New imaging technique stimulates particles to emit laser light, could create higher-resolution images.
Nanostructures made of pure gold
The idea is reminiscent of the ancient alchemists' attempts to create gold from worthless substances: Researchers have discovered a novel way to fabricate pure gold nanostructures using an additive direct-write lithography technique.
