Mars' rust-red color results from the oxidation of iron, which is when an oxygen-containing source (like carbon dioxide or water) steals an electron from an iron atom. Skip to content.

According to Casey Bryce, by the research team's calculations iron oxidation by nitrate-reducing bacteria may have initially compensated for the reduced contribution of phototrophic iron oxidizers.

While iron oxidation caused iron-rich minerals to drop out of solution as water temperatures rose from 5°C to 25°C, the precipitation of silica showed exactly the opposite trend, Konhauser says.

Iron is well-known for rusting, but this doesn't just happen on contact with oxygen and water. ... The team also measured a corrosion current, a direct sign of the oxidation of iron.

RECENT results1 show that for the oxidation of iron–chromium alloys containing 16–38 per cent chromium, in oxygen at atmospheric pressure, the process is controlled by diffusion during the ...

Together with colleagues, a group of scientists from Immanuel Kant Baltic Federal University synthesized nanostructures of gold and iron oxides that have improved magnetic and optical properties ...

Researchers studied ancient iron-oxidizing bacteria to understand their role in Earth's early iron formations. The study found that nitrate-reducing bacteria produced toxic nitrogen monoxide, ...
