It was discovered in 1774 by Scheele and isolated later that year by Johan Gahn. Manganese is one of the few elements that humans use on a daily basis. In 1774, a Swedish scientist named Johann Gottlieb Gahn was able to isolate manganese metal by reducing the compound of manganese dioxide. Remarkably enough, manganese has …

In plain carbon and alloy steels, manganese and sulfur are present at much lower percentages. They still form manganese sulfides, which promote machinability. If anyone comes across a heat of steel …

Understanding the governing dopant feature for cyclic discharge capacity is vital for the design and discovery of new doped lithium nickel–cobalt–manganese (NCM) oxide cathodes for lithium-ion battery applications. We herein apply six machine-learning regression algorithms to study the correlations of the structural, elemental features of …
