Role of Anions in the AuCl3-Doping of Carbon …

2011/1/5· The doping/dedoping mechanism of carbon nanotubes (CNTs) with AuCl 3 has been investigated with regard to the roles of ions and anions. Contrary to the general belief that CNTs are p-doped through the reduction of ionic Au 3+ to Au 0, we observed that chlorine anions play a more important role than Au ions in doping.

Nickel Alloys - an overview | ScienceDirect Topics

A synergism between H 2 S and Cl − extends the domain of SCC to lower temperatures, chloride concentrations and more hodic potentials (Rhodes, 2001). For SA and CW Ni-based alloys, a transgranular path is usually found (but not exclusively), whereas an intergranular SCC mode has also been observed on precipitation-hardenable Ni-based systems with σ-phase precipitation along grain …
