Latest Oxide Stories
New research from the University of Copenhagen and University of British Columbia (UBC) has revealed that oxygen appeared 700 million years earlier than we previously thought. The findings, published in the journal Nature, raises new questions about the evolution of early life.
An often-overlooked form of manganese, an element critical to many life processes, is far more prevalent in ocean environments than previously known.
Oxygen is a necessary component for the survival of most terrestrial life on Earth. The planet’s atmosphere, however, did not always contain this life-sustaining substance.
New synthetic nanoparticle could disinfect, depollute, and desalinate contaminated water and then get removed magnetically.
Life on earth began in the oceans, but it would eventually spread to land and a new study suggests that land-dwelling bacteria could have covered large swaths of territory about 2.7 billion years ago, despite a thin ozone layer that would have offered little protection against the sun’s ultraviolet radiation.
New biogeochemical understanding of manganese oxidation lends insight to environmental remediation
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...
- The act of sweetening by admixture of some saccharine substance.
