Figure 2From: Special phase transformation and crystal growth pathways observed in nanoparticles†The kinetics of hydrothermal coarsening of (a) uncoated and (b) mercaptoethanol-coated nanocrystalline ZnS. In (a), the kinetics are described by combined oriented attachment (OA) and Ostwald ripening (O-R). In (b) there are clearly two coarsening regimes. TEM and kinetic analysis indicates the first stage is dominated by oriented attachment. The second stage kinetics are described by combined (OA) and (O-R). (Fig. 2a from ref. 50.
