Figure 5
Distribution of calcium and sulfur in the microspheres. 3D-XRF images of 8 mM 1 g l−1 30 min with (a) a calcium xz plane, (b) a calcium xy plane, (c) a sulfur xz plane and (d) a sulfur 2D xy plane. On (c) and (d), the upper left corner of the image corresponds to calcium. This allows the sulfur and calcium signals to be visualized on the same image. Scale bar = 1 µm. Note S:Ca = 0.59.
