Like Earth, Mars was formed about 4.5 billion years ago, but its early surface was very different than today's. Mars' surface ...

The iron oxidation proceeded to form hydrides and siderites to imply a redox boundary. The findings shed light on the process of creating a reduced atmosphere that underlies the emergence of ...

The Great Oxidation Event a few years later changed all that. Approximately 4 billion years ago, low levels of oxygen appeared on Earth for the first time. A major reason for this is due to the ...

Early in the Earth’s development, the atmosphere contained no oxygen. Yet the iron dissolved in the oceans was ... which of them were primarily responsible for iron oxidation. “In order to better ...

Additionally, peroxy radicals are key intermediates in atmospheric oxidation processes, influencing the atmospheric lifetime of greenhouse gases and contributing to climate change dynamics.

It is generally recognized that oxygen concentrations above a certain percentage are oxygen-enriched atmospheres (OEA), but gen concentrations above a certain percentage to be an oxygen-enriched ...

Team from the Universities of Tübingen and Bristol hypothesizes the contribution of different bacteria to form today’s ...
