It can be seen that in Zr16Nb14Hf22Ta23Mo25 HEA, the constituent elements are uniformly distributed which is ensured by the high value of ΔSmix (13.18 J/K mol) for the present high-entropy system and the low values of ΔHmix among principal elements (Supplementary Table 2, 3)...
On the position of La, Lu, Ac and Lr in the periodic table: a perspective The periodic table of elements, organised as blocks of elements that contain similar properties, occupies a central role in chemistry. However, the positio... A Chandrasekar,M Joshi,TK Ghanty - 《Journal of Chemical...
10b). The coordination information of the Pt and Fe elements were further supported by the relative fitting results (Supplementary Fig. 11 and Supplementary Table 1). 57Fe Mössbauer spectroscopy was applied to identify the local structure of the Fe species. As shown in Supplementary Fig. 12 ...

We used EDS elemental mapping analysis to detect the spatial arrangement of the two metal elements in the Au@Pt. The green particles representing Au are more densely distributed in the center than in the periphery, thus confirming that Au is predominantly distributed in the nuclear structure. The...
13d), the sample showed a dominant peak at 1.7–1.8 Å, which can be ascribed to the coordination of Pt atom to light elements such as C or O. Clearly, no Pt–Pt bond was observed, indicating that all the Pt atoms were atomically dispersed on ND@G support, consistent with the...
