Spherulitic morphology
WebThe spherulitic structures are porous with large surface areas. Figure 3D reveals the polycrystalline nature of the nanostructures as the lattice fringe patterns have different orientations. The interplanar spacings were measured to be 0.17 nm and 0.23 nm, which correspond to Cu (111) and CuO (200), respectively. 34 Web22. dec 2004 · This randomization in the orientation accounts for the isotropy of spherulitic growth at large length scales and long times. In practice, many mechanisms can give rise …
