摘要：

The seeder of the pack: The electrical potential distribution (see phase image of an electron hologram) around the basal plane close to the prism faces of a hexagonal fluorapatite-gelatine nanocomposite seed influences the growth of the nanocomposite. The seed consists of elementary dipoles on the nanometer scale, which all have the same orientation along the c axis of the composite seed. Further form development of the seed leads to fractal patterns. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
