Electrode inlaid microdisk

In a typical voltammetric experiment, a constant voltage or a slow potential sweep is applied across the ITIES formed in a micrometer-size orifice. If this voltage is sufficiently large to drive some IT (or ET) reaction, a steady-state current response can be observed (Fig. 1) [12]. The diffusion-limited current to a micro-ITIES surrounded by a thick insulating sheath is equivalent to that at an inlaid microdisk electrode, i.e.,... 

At an inlaid microdisk electrode, the dependence of the dimensionless net peak current on the sphericity parameter is given by the following equation [31] ... 

Carbon microelectrodes decorated with enzyme were prepared with two different methods (Horrocks et al. 1993). Type A electrode (Fig. 3.15a) was prepared by heat sealing carbon fibers, with diameter of 11 or 8 p,m, in 2-mm outer diameter (OD) Pyrex capillaries. The resulting tip geometry was an inlaid microdisk electrode. The carbon microdisk was then coated with the electrically wired enzyme by soaking the... 

Recently, Michel et al. [169] carried out a numerical computation of the faradaic impedance of inlaid microdisk electrodes using a finite-element method and discussed the limitations of the Fleischmann and Pons [168] approach. Calculation of the functions 4 and 5 is shown in Exercise 4.8. 

Different from an inlaid microdisk electrode with expressed in equation 17.2.2, a recessed disk-shaped electrode with the geometry shown in Scheme 1, is given by an approximate equation...
