Enhancement of the optical and electrical properties of Cd-rich NixCd1−xO alloys was achieved through an electrochemical procedure – their biasing at a constant negative potential into an electrolyte. Depending on the conductivity of the film (correlated to x), the films changed their color from transparent-yellowish to black. For a certain bias, the coloration became permanent and irreversible. Electron...
The conditions for oxidizing multi-walled carbon nanotubes to shorten them to a narrow length distribution have been optimized. One of the most difficult achievements is to fully characterize this material from a chemical point of view, and to find a good quantitative correlation among different techniques. Herein, we report on the combination of different methods to determine the number of functional...
