Copper proteins and copper enzymes.
Ciba Foundation symposium, 1980The copper proteins that function in homeostasis, electron transport, dioxygen transport and oxidation are discussed. Particular emphasis is placed on the role of the ligands, their type and disposition which, in conjunction with other residues in the active site, determine the role of the copper ion.

A copper–copper bond by intent
J. Chem. Soc., Chem. Commun., 1994The ESR spectra for a series of binuclear trigonal bipyramidal copper complexes show that the SOMO is largely composed of the two equivalent dz2 orbitals on copper; the temperature independence of the ESR parameters shows that this is a relatively strong bond, and since the unpaired electron is antibonding, the σ-bond must be even stronger; these ...

Forming of Copper and Copper Alloys
2006Abstract This article reviews the general characteristics of copper and copper alloys and explains how these characteristics affect the behavior of strip in different types of forming operations. These forming operations include blanking, piercing, bending, drawing and stretch forming, spinning, rubber-pad forming, and contour roll ...

Introduction to Copper and Copper Alloys
1990Abstract Copper and copper alloys constitute one of the major groups of commercial metals due to their excellent electrical and thermal conductivities, corrosion and fatigue resistance, ease of fabrication, and good strength. This article lists the types, properties, fabrication characteristics, corrosion ratings, temper designations ...

Copper and Copper Alloy Castings
2008Abstract The properties of copper alloys occur in unique combinations found in no other alloy system. This article focuses on the major and minor alloying additions and their impact on the properties of copper. It describes major alloying additions, such as zinc, tin, lead, aluminum, silicon, nickel, beryllium, chromium, and iron.

The feedstock: copper and copper alloys
Metals Technology, 1975AbstractThe production of feedstock in the copper and copper alloy rolled-metals industry covers a very wide range of activities and no attempt is made to examine these in depth. A general review is given on the two principal methods used for producing slabs or cake for hot rolling, and of the four principal methods for producing generally smaller ...
