atomic weight 12.01115. Manganese (Mn): Manganese is a brittle, metallic element that exists in the ore of pyrolusite. When making steel, it reacts with sulfur and helps to increase the metal's ...

Schematic mechanism of S-doping of sol-gel processed ZnO film. Spin-coated thiocyanate ion (SCN?) is converted to active S species by heat treatment and migrated to oxygen vacancies by ...

Why Nature Chemistry spells sulfur with an 'f'. Many decisions must be made when setting up a new scientific journal. These range from perhaps the more fundamental considerations, such as what ...

Electron microscopy measurements are usually performed by collecting all points in a 2D grid. Here, using deep learning in ...

was less than the atomic mass (average mass of the atom). For example, a helium atom has an atomic mass of 4, but an atomic number (or positive charge) of 2. Since electrons have almost no mass ...

But what about sulfur? Nobody seems to think much about poor sulfur, and when they do it tends to be derogatory. Sulfur puts the stink in rotten eggs, threatens us when it spews from the mouths of ...
