Exposure Feature on Lab Clean Water Research

Heavy metals can contaminate drinking water sources, posing a threat to public health. Cases of drinking water contamination in Flint, Mich., and Newark, N.J., motivated research into the development of tiny, customized crystals that can detect and trap waterborne heavy metals like mercury and lead. This Exposure feature includes photos and 360° view of ALS beamline 11.3.1. More>
