Figure 5

Plot of normalized substrate concentration “ 𝑢 ” at a microelectrode modified with a conducting polymer film as a function of “ 𝜌 ”. The concentrations were computed for various values of Biot number “ 𝑣 ” when (a) 𝛼 = 0 . 0 0 1 , 𝛾 = 0 . 1 , (b) 𝛼 = 0 . 0 1 , 𝛾 = 0 . 1 , and (c) 𝛼 = 0 . 1 , 𝛾 = 0 . 1 . (solid line) (22); (dotted line) (17). Solid lines are compared with points. In this figure (i) 𝑣 = 0 . 1 , (ii) 𝑣 = 0 . 5 , (iii) 𝑣 = 1 , (iv) 𝑣 = 5 , (v) 𝑣 = 1 0 , (vi) 𝑣 = 5 0 .
