This transformation is diffusionless: The particles undergo coherent, local rearrangements. WebJan 11, 2024 · The crystallization pathway of ACC in the presence of Zn 2+ was first investigated by adding pre-mixed ZnCl 2 and CaCl 2 solution into Na 2 CO 3 solution, where the molar ratio of Zn 2+ to total cationic ions (Ca 2+ + Zn 2+) ranges from 0% to 20% and the concentration of total cationic ions and Na 2 CO 3 equals to 5 mM.
WebJul 3, 2024 · Mineralization is the most fundamental process in vertebrates. It is predominantly mediated by osteoblasts, which secrete mineral precursors, most likely through matrix vesicles (MVs). These vesicular structures are calcium and phosphate rich and contain organic material such as acidic proteins.
