General description
Copper powder (dendritic) is also known as an electrolytic copper powder (ECP) which has a dendritic shape with a particle size that is less than 4.5 μm. The dendritic shape of the copper particles can be produced by electrolytic deposition method.
Application
ECP can be used as a catalyst in the production of biodiesel by transesterification of soybean oil and partial hydrogenation of polyunsaturated compounds. It can also be used to form a metal composite with carbon nanotubes for the formation of high strength copper alloys.

A method has been developed for the preparation of N-alkynylated sulfoximines involving the copper-catalyzed decarboxylative coupling of sulfoximines with aryl propiolic acids. A range of substituents on both the sulfoximidoyl moiety and the aryl group of the propiolic acid were

Heavy metals in cells are typically regulated by PIB-type ATPases. The first structure of the class, a Cu(+)-ATPase from Legionella pneumophila (LpCopA), outlined a copper transport pathway across the membrane, which was inferred to be occluded. Here we show by
