Effect of different-sizes of hydroxyapatite on the water resistance of magnesium oxychloride cement for bone repair

“…A band at 1032 cm −1 was assigned to a n3 (antisymmetric stretching) and that at 478 cm −1 to a n4 (out-of-plane bending) vibration. 32 As Fig. 1(c) , the PO 4 3− -peaks and the O–H stretching vibration peaks were also observed in MOC/n-HA.…”

MD Study of Stokes Shifts in Ionic Liquids: Temperature Dependence

“…This is ascribed to high viscosity of BMI + PF 6 – , compared to the other two ILs we studied. (The viscosities of BMI + PF 6 – , EMI + PF 6 – , and EMI + Tf 2 N – are 28.8, 18.6, and 8.7 mPa s at 350 K, respectively. , ) Therefore, the BMI + PF 6 – system at 350 K is more likely to be trapped in local minima than at higher temperatures or other IL systems. Nonetheless, in view of the agreement with the other two ILs on the T -trend of Stokes shifts our MD statistics employed for BMI + PF 6 – appear to be reasonable.…”

“…For further insight into dissipative solvation dynamics, we investigate how the viscosity and solvation time are related. The temperature dependence of viscosity η of ILs can be described by the Vogel–Fulcher–Tamman (VFT) equation , where A , k , and T 0 are the fitting parameters. Using the parameters from refs and , the viscosity of the three ILs studied are calculated and plotted against the solvation time for the two different solutes in the ground and excited states in Figure .…”

Using the parameters from refs and , the viscosity of the three ILs studied are calculated and plotted against the solvation time for the two different solutes in the ground and excited states in Figure . The results show that there is a strong correlation between solvation time and viscosity irrespective of the IL species; solvation time increases with the IL viscosity.…”
