反应-扩散系统，其中一种试剂（外部电解质）通过扩散渗透到凝胶中，并与在凝胶中均质化的另一种试剂（内部电解质）形成沉淀，能够产生各种复杂的沉淀模式。先前研究的NaOH + AgNO 3和最近发现的CuCl 2 + K3[Fe（CN）6]过程（其中第一种试剂是外部电解质，另一种是在凝胶中均匀化的内部电解质），当使用上述方法反应时，能够通过依赖于所谓的反应前沿的回归边缘的动力学的机制产生平面的镶嵌。反应相的自发分配导致类似于Voronoi图或其概括之一的模式的构建。
Reaction-diffusion systems where one of the reagents (outer electrolyte) penetrates into a gel by diffusion and forms a precipitate with the other reagent (inner electrolyte) homogenized in the gel, are able to produce various complex precipitation patterns. The previously studied NaOH + AgNO3 and recently discovered CuCl2 + K3[Fe(CN)6] processes, (where the first reagent is the outer electrolyte and the other is the inner electrolyte homogenized in the gel), when reacted using the above mentioned method, are able to generate tessellations of a plane by a mechanism dependant on the dynamics of so-called regressing edges of the reaction fronts. The spontaneous partitioning of the reacted phases results in the construction of a pattern analogous to a Voronoi diagram or one of their generalizations.
