The cover picture shows a harlequin dancing in a room surrounded by transition metals. This character is a theatrical metaphor representing an ambiphilic ligand and its interaction with transition elements, which is the topic of the Microreview. The multiple arms describe the multidentate nature of ...
The chemical species involved in the reactions are composed of seven elements - H, He, C, O, N, S and Fe - with H and He dominating the elemental abundances. The model considers a chemical environment which is carbon-rich (i.e. C/O > 1)....
Neutral elements and central elements are characterized in different classes of posets such as sectionally semi-complemented posets, atomistic posets etc. MSC: Primary 06A06; 06A11; 06C05; 06D50 Keywords: standard element; distributive element; neutral element; central element [1] BIRKHOFF, G.: ...

Shiny black, air-insensitive crystals of tellurium-rich one-dimensional coordination polymers were synthesized by melting a mixture of the elements with TeCl4. The compounds [Ru(Te9)](InCl4)2 and [Ru(Te8)]Cl2 crystallize in the monoclinic space group type C2/c, whereas [Rh(Te6)]Cl3 adop...
This shows preferential removal of the intermediate REE from sea water, a pattern which has also been found in those TAG sediments formed from neutrally buoyant plume fallout. Chalcophile elements (Cu, Zn, Co, Pb, Sn) all appear to undergo release from plume particles at the same rate ( t...
