How much of the essential trace element iron remains available for marine life in the ocean depends critically on the diversity of organic molecules in seawater, according to new research published in ...

Every living organism uses tiny quantities of metals to carry out biological functions, including breathing, transcribing DNA, turning food into energy, or any number of essential life processes. Life ...

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

Scientists know iron oxide minerals store large amounts of carbon in soils, but lack a detailed, quantitative understanding of the specific chemical mechanisms that allow them to bind such a wide ...

Scientists have coaxed one of the universe’s most stubborn elements into a new compound. Formed under intense pressures, the newly discovered compound packs helium atoms into crystalline iron, ...

Iron is the main ingredient in various forms of iron and steel, but the various types of metals contain other elements as well. Sometimes these elements are unwanted; other times they're intentionally ...

Researchers at Nagoya University have created a more efficient iron-based photocatalyst that could reduce the need for rare and expensive metals in advanced chemistry. Unlike earlier designs, the new ...
