The water in our oceans, lakes and rivers can become polluted with a variety of contaminants, creating a need for a simple and cheap cleaning method. One team of researchers is designing magnetic ...

The technique is more efficient and can be used to print metal oxides, such as iron oxide (rust), which can then be reduced into metal. Rust powder is lighter, more stable, cheaper, and safer to ...

A multi-institutional team has directly observed electron hopping in iron oxide particles, a phenomenon that holds huge significance for a broad range of environment- and energy-related applications.
