aThe masses of atoms and molecules are characterized by using quantities known as the relative atomic mass of an element (the atomic mass in short) and the relative molecular mass of a substance (the molecular mass ) 原子和分子大量描绘的是为使用数量以元素(原子质量的原子量简而言之)和物质的分子...
the relative total metal atomic concentrations [(Pd + Pt)/(Pd + Pt + Ce)·100] at the surface and the subsurface regions are about 13 and 17 at.%, respectively (Table S7), which in the case of the outermost layer is substantially lower than the relative Pd atomic conc...

Magnetization promoted activity of magnetic catalysts towards the oxygen evolution reaction (OER) has attracted great attention, but remains a puzzle where the increment comes from. Magnetization of a ferromagnetic material only changes its magnetic doma
Despite the sample being in powdered form (at around 70–100 μm), the effect of crystal orientation, influencing the relative amplitudes of the Raman bands, is clearly visible (Fig. 10). This is due to the very small spot size of the laser limited to a single particular grain, ...
