Scientists design way to use harmless bacteria to detect heavy metals in drinking water

When it comes to testing drinking water for dangerous contaminants, such as heavy metals like lead or cadmium, continuous testing directly from faucets people drink from is important. Yet, very little of this kind of water ...

Separation chemistry: A step toward greener metal recycling processes

Liquid-to-liquid extraction is the basic process used in hydrometallurgy for recycling metals and decontaminating solvents (to recover molecules that can be re-used or to decontaminate them). Until now, the "recipes" used ...
