A car’s vibrations can power a new filter that captures air-polluting particles from the car’s exhaust (ACS Nano 2015, DOI: 10.1021/acsnano.5b06327). The researchers plan to develop the filter for commercial use in diesel and gasoline-powered vehicles.

Vehicle exhaust contains particulates that are linked to heart and lung disease. Particles with diameters smaller than 2.5 µm, called PM2.5, are linked to the . . .
