Researchers ‘detune’ a molecule (Natelson; 1/16/14)Rice University scientists have found they can control the bonds between atoms in a molecule. The molecule in question is carbon-60, also known as the buckminsterfullerene and the buckyball, discovered at Rice in 1985. The scientists led by Rice physicists Yajing Li and Douglas Natelson found that it’s possible to soften the bonds between atoms by applying a voltage and running an electric current through a single buckyball.
Optical antennas heat up (Natelson; 1/14/14)In recent years scientists have been taking advantage of the collective sloshing of electrons in metals (called plasmons) to build nanoscale optical antennas and manipulate light at length scales that are small compared to its wavelength in free space. These plasmons do come with a cost, however. Just as the sloshing motion of water in a bathtub eventually damps out, leaving the water slightly warmer, plasmon excitations can dissipate, warming up the metal structure. This kind of heating can be useful, as in photothermal medical treatments based on nanoparticles, or it can be an inconvenience.

In a new study, Hill and colleagues describe what they found in the data from Cassini: a new class of space particles — submicroscopic “nanograins” of electrically charged dust.
