A constant voltage of 5V has been applied to post-deposited Al electrical contacts on the VOx films and the respective current was measured as a function of temperature within the range 25-100ºC.
According to Smith et al. [24] at this thicknesses scale the V metal film is likely to be characterized by irregular metal islands rather than a continuous uniform film which is expected only at thicknesses above 10 nm.

This f0 value was inserted as a key parameter into the kinetic formalism by Moleko et al. [15] to calculate the composition dependence.
Solid lines correspond to a kinetic formalism by Moleko et al. [15].

The glass microparticles (considered the adsorbent) were prepared according to the composition and methodology developed by Fiori et al. [5].
Kinetic models of adsorption In this study, as well as in the kinetic studies conducted by Biškup and Subotic [11] and Shek et al. [12], the chemical reaction was considered the determining stage for the adsorption process.
