Copper is a beautiful and useful metallic element found throughout your home in both pure form and in chemical compounds. Copper is element No. 29 on the periodic table, with the element symbol Cu, from the Latin wordcuprum. The name means "from the isle of Cyprus," which was known for...
Nanometre-scale copper-rich precipitates in irradiated ferritic pressure vessel weld surveillance samples have been imaged directly in the field emission gun scanning transmission electron microscope. This is achieved by using the atomic number sensitivity of the high-angle elastically scattered electron ...
Embrittlement by the segregation of impurity elements to grain boundaries is one of a small number of phenomena that can lead to metallurgical failure by fast fracture. Here we settle a question that has been debated for over a hundred years: how can minute traces of bismuth in copper cause ...
Assessment of copper ores requires the establishment of both the total copper (TCu) content and the mode of occurrence of the copper, e.g., as oxide or sulfide minerals. In establishing the latter, cyanide soluble copper (CNCu) and acid soluble copper (ASCu) determinations are important. Th...
