β-TCP Ca/P ratios determined by Rietveld refinement with the hydrogen-substituted model. The platelet synthesis conditions are detailed in Table S1. Error bars designate two times the e.s.d. (95% confidence interval) determined by the refinement algorithm. The average Ca/P ratio was equal to 1.443 ± 0.003 (SD; n = 36) with no significant effect of any of the investigated synthesis parameters. |
