Figure 7
(a) Decomposition of Ca(HCO3)2 solution into CaCO3 patches and CO2 at the interface of an evaporating droplet (Accardo et al., 2011b  ). The raster-scan across the interface is schematically indicated. (b) WAXS raster-scan image of a whole droplet during evaporation. (c) WAXS pattern from the interface [rectangle in (b)] revealing two calcite crystallites via their 104 reflections. [Adapted from Accardo et al. (2011b).] (d) Time series of 100 ms µSAXS patterns during reactive mixing of CaCl2 and Na2CO3 recorded by a pixel detector. The time after the onset of the reaction (t = 0) when the corresponding pattern was collected and written to disk is indicated. Negative intensities around the beamstop (in white) are due to beam absorption by the merged droplets as the t = 0 pattern with the beam passing between the two droplets has been subtracted from subsequent patterns. SAXS intensity (in black) due to ACC particles is observed at t = 436 ms. (e) WAXS patterns at 2.87 min revealing a calcite crystallite via its 104 reflection. (f) Textured powder diffraction from residue due to calcite and vaterite phases. [Adapted from Accardo et al. (2013a).] |
