Fig. 6. Time evolution of the crystallinity, α, of Zr-fum in aqueous, formic acid modulated syntheses at 43 °C, as assessed by in situ energy-dispersive X-ray diffraction analysis. Inset is a typical 3D plot of diffraction data used to construct α vs. t individual curves. Reprinted (adapted) with permission from ref. 39. Published (2014) by The Royal Society of Chemistry.
