Cauliflower-like structure dendrites

This concept can be also applied for the case of the electrodeposition of copper. As mentioned earlier, the morphology of the copper deposit obtained at cathodic potential of -500 mV/SCE under the parallel field was of cauliflower-like structure (Fig. 12b), while the morphology of the copper deposit obtained without the applied magnetic field had very dendritic structure (Fig. 12a). It is known that dendritic structures are main characteristic of electrodeposition in conditions of full diffusion control, while cauliflower-like structures are a characteristic of a dominant diffusion in mixed control of electrodeposition process.13... 

The number, size, and distribution of holes in 3D foam or the honeycomb-like structures can be easily controlled by the choice of appropriate electrolysis parameters [20, 24, 25]. Also, the size of grains constructing dendrites or cauliflower-like agglomerates formed around holes, as well as the size of channels between small metal grains agglomerates, is controlled by conditions of electrolysis. The cauliflower-like agglomerates and dendrites among holes define the wall width in this structure type. The specific surface area of the 3D foam or the honeycomb-like... 

A channel structure (Fig. 3.4a), degenerate dendrites (Fig. 3.4b), and cauliflower-like forms (Fig. 3.4c) were formed by copper electrodeposition from 0.15 M CUSO4 in 0.125 M H2SO4. Holes originating... 

A special case is the formation of the balls of the size from about 200 pm containing deep cavities with the fem-like dendrites formed on the bottom of cavities and more or less dense cauliflower structure on the surface of these balls. Fig. 2.27d. The cross section of such agglomerate is shown in Fig. 2.28b. For some reasons this agglomerate started to grow as a ball, again starting from disperse (in the middle) and finishing with compact deposit at the surface for a reason...
