Abstract (English)

“Chemical” or “silicate gardens” are a well known example for the spontaneous formation of a complex and structured system from ordinary educts. Simply by addition of soluble metal salt crystals to alkaline silica sols, dissolution of the metal salt and subsequent solidification initiate a self-organization process, which not only produces two separated compartments with drastically different ...
