Window screens can filter pollutants

A group of Chinese scientists have developed an affordable window screen that can block nearly all hazardous particulates, including tiny PM2.5 particles, its developers said.

The breakthrough was produced by a team led by materials science professor Yu Shuhong with the University of Science and Technology of China - also a three-time winner of the State Natural Sciences Award - according to their newly published paper in iScience, an open-access journal of Cell Press, based in the United States.

The online version is now available on the journal's website and will be in the print edition on Feb 22.
