Scientists tap robots and AI to make new materials to curb air pollution

Instead of making and testing samples by hand over weeks or months, researchers at the University of Tennessee use smart robots that can produce and test at least 100 different materials within an hour.

Many human activities release pollutants into the air, water and soil. These harmful chemicals threaten the health of both people and the ecosystem. According to the World Health Organization, air pollution causes an estimated 4.2 million deaths annually.
