Borate polyanion-based systems as Li- and Mg-ion cathode materials
… M2B2O5, and orthoborates, M3(BO3)2, where M = Mg, Mn, Co, Ni, as high capacity and high voltage Li- and Mg-ion cathode materials. We explore the layered orthoborates (M3(BO3)2 which, to our knowledge, have not been previously considered as Li- or Mg-ion cathodes, perhaps due to the lack of Li …

CO₂ Mineralization Using Reactive Species
… CO? with the species such as Ca°? and M°? ions that are already present in sea water was studied. A series of experiments conducted at temperatures in the range of 20 to 40°C showed that the activation energy for the formation of nesquehonite (MgCO?°3H?O) is 64.6 kJ/mol. It was found that …

Studies into Mg-preconditioning of brewer’s yeasts
… cells, which were physiologically “preconditioned” with Mg ions, had improved fermentative output and stress tolerance. Ale and lager yeast cells preconditioned in the presence of elevated levels of Mg-actate, yielded highest cellular Mg contents in malt extract broth and dilute brewer’s wort …
