Silver is one of the heavy metals and can be toxic to aquatic animals43. However, we cannot explain why Ag was higher in male dugong tusks. According to some reports in the literature, it is believed that gender slightly influences the accumulation of heavy metals in the body18,31,44. ...
We have found that isomerisation, Cring closure and opening activity of Rh, Pd, Ir and Pt can be correlated with their f.c.c. structure, and their atomic dimensions being in a narrow range. These four metals promote single hydrogenolysis whereas multiple fragmentation is the only reaction ...

Metals： Metallic materials are normally combinations of metallic elements． They have large numbers of nonlocalized electrons；that is，these electrons are not bound to particular atoms. Many properties of metals are directly attributable to these electrons． Metals are extremely good conductors of elect...
View PDFHighlights The bigger picture We aim to present a creative approach to afford dual-atom bimetallic catalysts in a controlled and modular manner. This directly allows the combinations of different late 3d metals (forming M1-M2-supported dual atoms) and shows extensive possibility not limited...
For all those metals, however, the moiré modulation of graphene's electronic properties goes along with a modulation of its chemical reactivity, inducing preferential sites for adsorbtion or functionalization. This makes moiré superlattices efficient to self-organize arrays of metallic clusters36,37 ...
To modify the physical and chemical properties of photocatalysts, non-metallic elements such as C, S, Cl, N, H, P, B, and F [[43], [44], [45], [46], [47], [48], [49], [50]], as well as metallic elements such as Fe, Ni, Cu, Sn, and rare earth metals [[51], [...
