Diffusion at ultramicro disk electrodes: chronoamperometric current for steady-state EC' reaction using scattering analogue techniques

Article Abstract:

Accurate polynomial expressions are derived for steady-state current at disk microelectrodes with a pseudo-first-order EC' reaction. These polynomial expressions were obtained through the use of a scattering analogue method originally proposed for soil infiltration studies. A two-point Pade approximant that shows excellent agreement with digital simulation data is also reported when the methodology is extended to chronoamperometric current for diffusion-controlled processes.

Further insight into the dissociation mechanism of glass electrodes. The response in heavy water

Article Abstract:

A study was conducted to show that the functioning of glass electrodes in heavy water correlates with the same mechanism in light water, with differences in the isotope effect. The dissociation mechanism in heavy water was determined by several experiments. Experimental results indicated that the electromotive efficiency of the membrane glass was below unity. It was independent of glass composition and surface group.
