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 ...

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 ...

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 ...

Scientists have discovered that the Moon is rusting due to oxygen particles originating from Earth. These particles travel through space and interact with iron-rich minerals on the lunar surface, ...

Figure 1: Photomicrographs showing features similar to those previously described, and a graph comparing the size of each. Figure 2: Raman spectra collected from vein-fill minerals, the matrix, and a ...

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 ...

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 ...

Photoelectrochemical (PEC) water splitting promises a solution to the problem of large-scale solar energy storage. However, its development has been impeded by the poor performance of photoanodes, ...
