The Periodic Table is a creation of the nineteenth century and according to Rouvray and King ( 2004 ) there were six independent discoverers: de Chancourtois 1862, Newlands 1864, Odling 1864, Hinrichs 1867, Meyer 1868, and Mendeleev 1869. Mendeleev's version became the most famous and it ...

4b), and discriminate adjacent elements in Periodic Table. Generally, utilization of such energy-filtered fluorescence detector can effectively suppress the interference from undesired elements in leading to an energy-filtered EXAFS spectrum, which is peculiarly significant for atomically dispersed ...
N/A Interpretation of XPS spectra Sc2p peak has significantly split spin-orbit components (Δmetal=4.90eV). Splitting Δ-value varies with chemical state. (e.g., Δoxide=4.3eV for Sc2O3). For many elements, the FWHM for each spin-orbit component is the same, but for scandi...
