Generally, rust is thought of as making water dirtier and unhealthy. Now, a new study has found a way to use rust and magnets to clean water. For this, researchers used nanoparticles that they call ...

It's not unusual to find rust around salt water, but now the pairing might actually be useful. Researchers at Caltech and Northwestern University have found that electricity can be produced when salt ...

Pouring flecks of rust into water usually makes it dirtier. But researchers have developed special iron oxide nanoparticles called 'smart rust' that actually makes it cleaner. The magnetic ...
