Abstract:
Fractal patterns are commonly found during the re-crystallization process of over-saturated solution. In this work, the authors initially choose the gelatin aqueous solution, of high weight percentage of 18.2-27.3 wt %, dissolved with excess amount (9 wt %) of a photo-sensitizer agent potassium dichromate (K2Cr2O7) and sodium chloride (NaCl) to generate the tree-like, dendrite, fractal micro structures with the feature size of 5-40 μm. They also tried to make the fractal patterns uniformly to some extent according to Feynman's confinement statement. The smaller field for growing fractal gelatin has the survival percentage of 80 %, over the survival percentage of 55 % for the 5000 μm larger case. These fractal patterns are going to develop the application to the fabrication of new chaotic mixers.
