Haematite (α-Fe 2 O 3) has emerged as one of the most promising materials to carry out the light-driven water-oxidation half reaction for photoelectrochemical (PEC) water splitting 1,2,3,4,5,6. The ...

The timing of the origin of photosynthesis on the early Earth is greatly debated. It is generally agreed, on the basis of the presence of biological molecules found in shales from the Hamersley Basin, ...

The Spirit rover on Mars has identified haematite at a location half way around the planet to where its twin buggy Opportunity found the same mineral. Haematite is normally formed in the presence of ...

Researchers have now analyzed the optoelectronic properties of rust (haematite) and other metal oxides in unprecedented detail. Their results show that the maximum achievable efficiency of haematite ...

Physicists at the universities of Oxford and Cambridge in the UK have spotted signatures of magnetic monopoles and other unusual magnetic structures in haematite, a naturally occurring ...

Something unusual appears to be happening on the Moon, and Earth may be playing a part. Researchers have reportedly detected haematite, a form of iron oxide commonly known as rust, on the Moon’s ...

Measuring the kinetics of water oxidation on the haematite surface when it exposed to sunlight. Courtesy: C Mesa, Imperial College London An enzyme called photosystem II (PSII) in plants oxidizes ...

If correct, the microfossils, thought to have formed between 3.77bn and 4.28bn years ago, offer the oldest direct evidence of and insight into life on Earth Scientists say they have found the world’s ...

Rust in the form of haematite has been detected on the Moon’s surface, especially at the poles Haematite formation on the Moon requires oxygen and water, which are scarce on the lunar surface Earth’s ...
