A nanoparticle boost for solar-powered water heating

Scientists analytically studied the optical absorption efficiency of a TiN nanoparticle and found that it has a broad and strong absorption peak thanks to lossy plasmonic resonances. Surprisingly, the sunlight absorption efficiency of a TiN nanoparticle outperforms that of a carbon nanoparticle and a gold nanoparticle.

Engineers make nanoscale 'muscles' powered by DNA

By carefully incorporating strands of custom DNA into different layers of flexible films, researchers can force those films to bend, curl and even flip over by introducing the right DNA cue. They could also reverse these changes by way of different DNA cues.
