Researchers at The University of Texas at Arlington have discovered a surprising new type of magnetic property that could ...

Scientists once believed our planetary next-door neighbor got its rusty hue from hematite, a common iron ore known for its ...

By examining cheaper chromium–iron alloys, the authors have found these to be resistant to oxidation under the conditions that are necessary for iron oxide reduction in molten electrolyte.

Reduction rates vary considerably. In oxygen- free soils or sediments, iron oxides play a major role as acceptors of the released electrons. But how do the electrons get from respiration in the ...

“We show that rates of iron oxide reduction by reduced EES scale with the free energy of the less exergonic [less favourable] first of the two electron transfers,” says Aeppli. Moreover, the “free ...

An iron oxide 'oxygen sponge' for efficient thermochemical hydrogen production Date: May 29, 2025 Source: Pohang University of Science & Technology (POSTECH) Summary: As the world shifts toward ...

Early in the Earth's development, the atmosphere contained no oxygen. Yet the iron dissolved in the oceans was oxidized in ...

When ignited by a source of high heat, thermite compounds undergo an exothermic reduction-oxidation (redox) reaction as the aluminium reduces the number of electrons in the iron oxide atoms.

The steel industry has never had any reason to switch to electrolysis, since iron oxide is easily reduced by carbon to produce molten iron.

Without sulfates, iron and manganese oxides may have been essential in converting methane to carbon dioxide. "Sulfate comes mostly from oxidative weathering of rocks," said Beal.

The researchers have shown that the energy difference between the first electron transferred from the EES to the iron oxide determines the iron reduction rate. Using this concept, it is possible to ...
