In the example of calcium phosphate compounds, the newest Ca : P ratio roughly corresponds to brand new crystalline phase composite. EDAX characterization was did to help you look at the this new progression away from essential structure (get a hold of digital supplementary material, shape S1) and the relevant Ca : P beliefs was indeed determined and described within this digital second issue, desk S1, that also shows the brand new popular sales between the outer and you may inner surfaces. It can be inferred these particular development morphological variations of the biomass shells have been directly connected with the distinct natural constitution actually for the same piece of procedure.

So you’re able to define the new low practical groups and you will crystalline stage composition of all the biomass shells, attenuated full reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and you will X-beam diffraction (XRD) proportions have been performed (shape 2).
