Powdered copper is sometimes used as a pigment in paints. An important use of copper is in alloys such as brass, bronze, gunmetal, Monel metal, and German silver. Compounds of copper are widely used as insecticides and fungicides; as pigments in paints; as mordants (fixatives) in dyeing;...
it is somewhat soft. Another property of copper is its excellent ability to conduct heat. Copper does not succumb to corrosion like some other metals, nor does it oxidize or rust like iron. Copper in fact is resistant to many organic compounds, and perhaps its most valuable property is its...
electronically enforced elongation of one or two copper-donor bonds, and also for an analysis of the steric repulsion between the co-ligands (NCCH3, OH2, Cl–, NO3–) and the bispidine backbone (primarily the 6-methyl substituents of the pyridine donors) in the three isomeric chromophores....

Introduction Separation of metal ions and low-molecular-weight organic compounds using polymer inclusion membranes has been proposed as an environmentally friendly separation technology [1,2,...
Copper slag (CPS) is a large amount of waste material produced during the manufacture of copper. The disposal of this waste material becomes a problem for environmental concerns. Therefore, it is necessary to explore feasible alternate disposal options.
CuO, CuS and CuF2 have been used as fillers in polyetheretherketone (PEEK) and the influence of these fillers on the friction, wear and transfer behavior of the PEEK composites has been studied. Sliding tests were conducted with a pin-on-disk machine at 1.0 m s−1 speed and 0.65 MPa no...
