from this simulation shown in Fig.4, which is because reducing of initial melt temperature will increase the degree of undercooling and spur the fast growth of crystal. The final length of primary... are the coldest parts of the dendrite due to the large curvature here. The maximum of the temperature during the crystal growth varies with space and time. The Fig.2 Sequence of four times slices shown......

film can induce HAP crystal with different growth style and crystal morphology. The HAP induced by the film with -NH2 head groups is the nano-platelet crystal with regular orientation and order array. On the film with -SO2-3 head groups, radiated growth style of HAP crystal is mediated. While the HAP crystal induced by the film with -PO3-4 head groups has neither regular orientation nor order......
