From: Linking aggregation of Aspergillus niger spores to surface electrostatics: a theoretical approach
Influence of the thickness of the surface coating on the electric potential distribution at low bulk pH. Each diagram shows potential profiles as determined for several different electric field contributions of the spore wall. Calculation conditions are as follows: σ=0.02 C m−2 (___), 0.015 C m−2 (-----), 0.01 C m−2 (-----), 0.005 C m−2 (-----); δ=10 nm (a), 5 nm (b), 3 nm (c);
