The surface diffusivities determined by assuming surface diffusion control, pore diffusivities assuming pore diffusion control, and the effective diffusivities for the homogeneous model (Deff) obtained from the uptake curves varied with the concentration of the dye and the stimulator (NaCl).
At high potentials diffusion control prevails.
Average particle size of >91 µm depicted pore diffusion control.
These cavities at the outer edges suggest diffusion control.
The redox reaction of Cyt c in the present SAMs was a diffusion control process.
Equivalent series resistances, charge transfer resistances and diffusion control were studied by electrochemical impedance spectroscopy (EIS).
Numerical solutions were found to match the analytical solution of the traditional model when the adsorption isotherm is linear, for macropore diffusion control or micropore diffusion control.
At a given reaction temperature and gas flow velocity, the SPP reaction mechanism changes from interior diffusion control to surface diffusion control with decreasing particle size.
In sulphuric acid solution nucleation proceeds through 3D instantaneous nucleation under diffusion control, and in phosphoric acid solution nucleation proceeds through 3D progressive nucleation under diffusion control.
Internal diffusion control and external diffusion control models of TaC coating growth were established on the basis of mass transfer and reaction dynamics theory.
Two well defined regions for different rotation rates have been observed having (a) pure diffusion control, and (b) mixed kinetic and diffusion control.
