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.
Using new photonics technology, European scientists are developing a multi-gas detector that can spot dozens of harmful emissions with a single sensor in milliseconds, delivering a breakthrough for the prevention climate change.
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.
A team of mechanical engineers has successfully used acoustic waves to move fluids through small channels at the nanoscale. The breakthrough is a first step toward the manufacturing of small, portable devices that could be used for drug discovery and microrobotics applications.
