A filter for environmental remediation

A team of researchers at Osaka University has developed a nanopowder shaped like seaweed for a water filter to help remove toxic metal ions. Made of layered sodium titanate, the randomly oriented nanofibers increase the efficacy of cobalt-II (Co2+) ion capture. This work might lead to cheaper and more effective solutions for filtering water that is currently unusable due to hazardous heavy metals or radioactive fallout.
