    manganese (countable and uncountable, plural manganeses)

      • 2013 September-October, Katie L. Burke, “In the News”, in American Scientist‎[1], archived from the original on 27 June 2015:
        Oxygen levels on Earth skyrocketed 2.4 billion years ago, when cyanobacteria evolved photosynthesis: […] . The evolutionary precursor of photosynthesis is still under debate, and a new study sheds light. The critical component of the photosynthetic system is the “water-oxidizing complex”, made up of manganese atoms and a calcium atom.
      • 2014 April 21, “Subtle effects”, in The Economist‎[2], volume 411, number 8884, archived from the original on 20 January 2021:
        For the past ten years Brad Racette, a neurologist at Washington University in St Louis, Missouri, has been tracking those effects, paying special attention to welders, since they are exposed to more manganese than most people. Being harder than iron, manganese is often used to strengthen steel and is present in many industrial emissions, including welding fumes.
    3. (countable) An atom of this element.
