Researchers at Rice University have developed a simple water filtration material so effective that a single gram of it can treat up to 83,000 liters of contaminated water, after which it can be washed with vinegar and reused. After a trip to India, where he saw the connection between e-waste and groundwater contamination as a high-schooler, and then working with Rice chemist Andrew Barron, Perry Alagappan, now an undergraduate student at Stanford University, developed a
Reusable carbon nanotube water filter removes 99 percent of heavy metals
