Gedanken zur empfindlichen Kristallisation mit Kupferchlorid
Im Anschluß an die Arbeit von R. E. Hummel: Liefert die KupferchloridwKristallisations-Methode einen Nachweis für die Gestaltkräfte des Lebendigen?
In the field of the sensitive crystallization with copper-chloride are known as effective substances proteins, natural polymers and polyvinylpyrrolidone. This refers to long-chained macromolecules. Their formation made by coupling monomers could be understood as an one-dimensional process of crystallization. The phenomena, which could be observed and found out on the process of sensitive crystallization, are indications for selforganisation - as on each process of crystallization. It clearly shows that media, fit for crystallization, are provided with the quality of organisms and the facts of crystallization are an expression of life-processes. The character of unity concerning the patterns built by the needles of copper chloride is disposed by the flows in the liquid phase before nucleation begins. In case of crystallization in a shallow layer it refers to Marangoni currents, which are powered by gradients of the surface tension. The reproduction of the same pattern is based upon the material property of the surface tension of the solvent with the same additiv and its connection to temperature and consistency.
