Oxides or hydroxides of divalent metal
ions are effective high-ortho catalysts.

coordination polymers incorporating the kinked and hydrogen-bonding capable tethering ligand 4, 4"-dipyridylamine, Coord Chem Rev, 253, 1759 (2009).
Removal of large range of divalent metal
ions was carried out using sugar beet pulp as biosorbent material  and study revealed very good removal efficiency.
The possible mechanism may be competitive binding to the divalent metal
transporter 1 protein, which participates in divalent metal
transport (Fe, Cu, Zn, Mn, and Pb) .
As the name implies, in enzymes activated by metals, catalysis is triggered by the presence of a mono- or divalent metal
ion on the outside of the protein.
The three groups did not differ significantly with regard to cellular HEPH and divalent metal
transporter 1 (DMT1) expression.

ions and protons," Environmental Science & Technology, vol.
Since the elasticity of fracturing fluid may enhance its ability to transport proppants [18, 44, 45], these divalent metal
ions need to be shielded when the flowback fluid is recycled and reused.
The lattice structure of LDHs, with the general formula [[[M.sup.2+.sub.1-x][M.sup.3+.sub.x][(OH).sub.2]].sup.x+][([A.sup.n-]).sub.x/n]*y[H.sub.2]O, has a positively charged brucite-shaped layers, consisting of a divalent metal
ion [M.sup.2+] (e.g., [Ca.sup.2+], [Zn.sup.2+], [Mg.sup.2+], and [Ni.sup.2+]) octahedrally surrounded by six OH- hydroxyl groups [16-18].
The complexation of pectin with chitosan or the crosslinking of pectin by divalent metal
cations such as [Ca.sup.2+] decreases the permeability, solubility, and disintegration extent of the polymer structure but increases the density and mechanical strength of the dosage form , thereby delaying the release of the drug.

ions onto sphagnum moss peat," Water Research, vol.
