Copper on carbon materials: stabilization by nitrogen doping

Nitrogen doping of amorphous carbon thin films

Nitrogenated and hydrogenated amorphous carbon (a-C:H:N) films have been deposited by a plasma beam source using a gas mixture of C2H2 , Ar and N2 . The Ar/C2H2 ratio is kept constant at a ratio of 3, with the nitrogen flow allowed to vary. Nonnitrogenated films, with Ar/C2H2 ratios of 3 and 6 were also deposited and analyzed before attempting to identify the modifications to the microstructura...

MATERIALS CHEMISTRY COMMUNICATION Nitrogen-containing carbon nanotubes

could be prepared by employing appropriate precursor molecules. Nanotubes containing both boron and nitrogen have Carbon nanotubes containing small amounts of nitrogen are been grown in the electric arc discharge between graphite produced by the pyrolysis of aza-aromatics such as pyridine, cathodes and graphite anodes filled with boron in a nitrogen methylpyrimidine and triazine over cobalt nan...

Utilization of Soil Stabilization with Cement and Copper Slag as Subgrade Materials in Road Embankment Construction

In this study, unconfined compression tests have been conducted to investigate the impacts of copper slag on mechanical characteristics for stabilized cement and un-stabilized soil. Dozens of specimens were prepared at four percentages of cement (i.e. 0%, 2%, 4% and 6%) and five percentages of copper slag (i.e. 0%, 5%, 10%, 15% and 20%) by weight of dry soil. The samples compacted into a cylind...
