The experimental rotating disc electrode curves have been analyzed with the help of a kinetic model, in order to shed light on the predominant HOR mechanism (Heyrovsky Volmer vs. Tafel Volmer), the nature of the rate determining step, and their dependence on the Pd coverage, and get an insight into the type of HOR intermediate.
To illustrate the impact of the charge-transfer mechanism on ΔΦ, we show its dependence on the molecular coverage Θ in Figure 8. Starting with the Cu/TCNE system, where both PBE and PBEh* unanimously yield FCT, we find an approximately linear dependence of ΔΦ on the coverage with both functionals.
A dynamic mathematical model based on a Temkin-type desorption process for NH3 and a SCR reaction rate with a complex dependence on the ammonia surface coverage is well suited to represent the data.
This anticipates a pronounced impact of the growth mode on the coverage dependence of ΔΦ, which we will return to momentarily.
The promotion of the direct pathway by aniline adsorbed from solution followed a dependence on surface coverage that suggests inhibition of poisoning by adsorbed carbon monoxide.
Campaign outcome dependence on timing, coverage, and compliance.
An overall analysis of θ dependence on MFB coverage area is represented in Figure 6(b) left; θ denotes biphasic behaviour towards the number of MFBs per measured area.
Achieving and measuring these community-level effects and their dependence on ITN coverage on scales large-enough to be representative remains notoriously difficult [ 31] but is nevertheless essential for planning national control programmes [ 14].
The relationship of the coverage to the quality of diagnosis and control is analytically expressed, and the monotonic dependence of the system level reliability on the coverage is formally established.
In sober and idealistic tones, Mr. Mailer, who smokes marijuana "occasionally," he said, described his plan to wean the magazine off its dependence on "the plant" -- not to eliminate coverage, but to make it part of a broader diet of lifestyle articles.
