It’s the shape and porosity, not the size, of metal oxide particles that matter for efficiency in electrochemical ironmaking. Iron and its alloys, such as steel and cast iron, dominate the modern ...

A new “smart rust” could one day help pull pollutants out of waterways, leaving cleaner water behind. Researchers adorned tiny particles of iron oxide, better known as rust, with “sticky” molecules ...

Iron and its alloys, such as steel and cast iron, dominate the modern world, and there's growing demand for iron-derived products. Traditionally, blast furnaces transform iron ore into purified ...
