Two new different-bond-type hybrid compounds, (Hg6P4Cl3)(PbCl3) (1) and (Hg23P12)(ZnCl4)6 (2), with supramolecular interactions between host and guest moieties, which based on metal-pnicogen, pnicogen-pnicogen, and metal-halogen bonds were obtained by solid-state reactions. Compounds 1 and 2 show large second-harmonic-generation (SHG) activity and are transparent in the wide mid-IR region, prov...

The reactions of P/S-precursors with coinage metal alkoxides and carboxylates offer new perspectives for the synthesis of complex metal aggregates.

DFT calculations and X-ray crystallography were used to directly compare the reactivity of the convex carbon surfaces of C20H10-corannulene and the C60-fullerene toward the diruthenium(I,I) metal cluster.

a pvc membrane electrode based on 1-[({[(butylsulfunyl)carbothioyl]disulfanyl} carbothioyl)sulfanyl]butane as a suitable ion carrier for determination of lanthanum(iii) ion was prepared. this electrode revealedsuch a good selectivity toward la3+ ion over a wide variety of other metal ions. some experimental parametersuch as membrane composition, nature, and amount of plasticizer, the amount of ...

Introduction etal-on-metal bearings for hip replacement are gaining popularity as an alternative to the most widely used bearing couple of metal on polyethylene. The recent resurgence of hip resurfacing with the socalled third and fourth generations of hip resurfacing arthroplasty devices has played a substantial role in the wider use of metal-on-metal bearings. Concerns about the wear of polye...

reaction, which occurs under mild conditions and at low concentrations of reactants, is absolutely dependent on the presence of bivalent metal ions, and is stimulated by univalent metal ions. The most effective bivalent metal ion was found to be Ca++. When Mn++ ion was used to satisfy the bivalent metal ion requirement, the most effective univalent metal ion was found to be Kf. The reaction was...

Binding of a transition metal ion to specific sites in concanavalin A induces the formation of specific Ca(2+) ion-binding sites. Sites for binding alpha-methyl d-glucopyranoside exist only when a transition metal ion and Ca(2+) ion are bound.
