Two billion years ago the Earth system was recovering from perhaps the single-most profound modification of its surface environments: the oxygenation of the atmosphere and oceans.
If a new study based on fossil amber is correct, then the atmosphere of the Cretaceous had a relatively low oxygen content – making the high-oxygen theories severely flawed.
Reportbuyer.com just published a new market research report:
In the oldest, most pristine rocks, oxygen -- the most abundant element in the Earth's crust -- follows a strange, anomalous pattern that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth.
Brookhaven Lab scientists use simple, 'green' process to create novel core-shell catalyst that tolerates carbon monoxide in fuel cells and opens new, inexpensive pathways for zero-emission vehicles
Researchers, publishing a paper in the journal Nature Communications, say their study on methane's secrets will help scientists better understand the chemistry of planetary interiors.
Phosphorus & Derivatives Market research report categorizes the global market for phosphorus and its derivatives on the basis of applications, type and geography; forecasting volumes and revenues.
Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...
