WebSep 14, 2005 · Selective nucleation of aragonite can be achieved at ambient conditions in water by using block copolymer microgels at a very low concentration (0.1 ppm). One polymer template particle is sufficient to control the nucleation of a ring of aragonite single crystals, which propagate into a sheaf structure (see SEM image). WebCrystal nucleation is the process that begins in a liquid or solution phase and leads to the formation of molecular proto-aggregates (nuclei, embryos) that may then evolve into macroscopic crystals by the further process of crystal growth.
