The replacement of the nondescript term ‘heavy metals’ by a biologically and chemically significant classification of metal ions
TL;DR: In this article, the authors proposed a classification of metal ions according to their binding preferences (i.e. whether they seek out O-, N- or S-containing ligands).

Magnetic nanoparticles: essential factors for sustainable environmental applications.
Samuel C.N. Tang,Irene M.C. Lo +1 more
TL;DR: This review aims to provide a holistic overview of current knowledge of magnetic nanoparticles in environmental applications, emphasizing studies of zero-valent iron (nZVI), magnetite (Fe3O4) and maghemite (γ-Fe2O3) nanoparticles.

Hard and soft acids and bases ― the evolution of a chemical concept
TL;DR: In this article, the authors deal mainly with the more recent developments of the concept of chemical hardness, and a necessary summary of the early work is given, together with a discussion of the most recent developments.
Journal ArticleDOI
Immobilized metal ion affinity chromatography
TL;DR: This review covers the principles and practice of IMAC that can be performed under very mild, nondenaturing conditions, and the immobilized metal ion ligand complexes are more likely to withstand wear and tear than are antibodies or enzymes.

TL;DR: The three-dimensional structure of plastocyanin, a blue or "Type 1" copper-protein, has been determined at a resolution of 2.7 A as discussed by the authors, and it is coordinated by a cysteine thiol group, a methionine thioether group and two histidine imidazole groups.
