Fig. 7From: Continuum modelling of structure formation of biosilica patterns in diatomsCircular stationary patterns: Concentration profiles of component C within a circular boundary for different dissociation constants (columns, \(\beta = 0.15, 0.1, 0.01, 0.001\)) and initial concentrations of components A and B ( \(c_{\rm{A,0}} = c_{\rm{B,0}} = 0.2, 0.25, 0.4, 0.5 \)). The radius of the simulation cell was \(r = 40\). Bright regions correspond to the organic-rich phaseBack to article page
