The presence of either copper(I) or copper(II) chloride in the polyol reduction of silver nitrate facilitates the production of silver nanowires. Silver nanowires have applications in many areas, including electronics and catalysis. These wires are produced quickly (in approximately one hour), with the synthesis being easily performed in disposable glass vials, using only pipettes to deliver re...

The title complex, [Cu(C(4)H(5)O(6))(2)(H(2)O)(2)]·2H(2)O, contains a Cu(II) ion lying on an inversion centre. The coordination geometry of the Cu(II) ion is a distorted octa-hedron with four O atoms from two hydrogen tartrate ions occupying the equatorial positions and two O atoms from two coordinated water mol-ecules occupying the axial positions. In the crystal structure, inter-molecular O-H...

In the title compound, [Cu(C(5)H(7)O(2))(C(2)N(3))(C(12)H(8)N(2))]·2H(2)O, the Cu(II) atom is five-coordinated in a square-pyramidal geometry with two acetyl-acetonate O and two phenanthroline N atoms forming the base. The apical position is occupied by the central N atom of the dicyanamide ligand. The dicyanamide N atoms are each involved in hydrogen bonds to water mol-ecules. There are also h...

The asymmetric unit of the title compound, [Cu(C(4)H(8)NO(3))(C(12)H(8)N(2))(H(2)O)]Cl·2H(2)O, contains a complex cation, a chloride anion and two water mol-ecules. The Cu(II) ion has a distorted square-pyramidal coordination geometry formed by one bidentate phenanthroline ligand, one O,N-bidentate dl-threoninate ligand and one apical water mol-ecule. In the crystal structure, inter-molecular O...

Dialysis rates of cholesterol, calcium chloride dihydrate and of their mixture in 90% aqueous dioxane through Visking cellulose membrane were characterized by half-escape times (t1/2) of 2.2, 1.0 and 10.5 hours, respectively. Slow dialysis rate observed with the mixture was due to complex formation between four molecules of cholesterol and two molecules of calcium chloride dihydrate, molecular ...

Fe is an impurity in most leach liquors. Its coexistence with copper in leaching solution of chalcopyrite (CuFeS2) which is the most important mineral of copper creates major extraction problems. Hydrochloric acid dissolves both copper and iron during chloride leaching of this mineral. Separation of Fe from Cu is thus necessary to obtain pure copper. This paper presents a novel metho...
