Fig. 8 Bright field STEM images of Na-EMAA showing three distinct phases. Phase I is featureless on the STEM length scale, phase II contains small spherical aggregates, and phase III contains large spherical aggregates. The designations a and m denote the locations of energy dispersive x-ray spectra taken of the aggregates and the matrix, respectively (data not shown, see Ref. ).

Figure 2. Electron microprobe energy dispersive x-ray spectra of two vitrain grains from the middle part of the Beulah Zap bed and an ulminite grain from the upper part of the seam. Analyses were accumulated for 400 seconds with a current of 1000 picoamps with the beam scanning areas of 10-100 square microns.

Figure 10,2 Typical scanning electron microscopy (a,b) and transmission electron microscopy images (e,f) of synthetic and eggshell-derived calcium-deficient hydroxyapatite. Energy-dispersive X-ray spectra (c,d) and selected area electron diffraction pattern are shown in the inset.

Figure 2.3 represents the scanning electron microscopy and energy dispersive X-ray spectra of branched crystal pattern. 

Figure 1 Energy dispersed X-ray spectra from the same sample excited by 20 keV electrons (top) and 2.5 MeV protons (bottom). The enhancement of the detection limit for the trace elements caused by the absence of primary Bremsstrahlung in the PIXE spectrum can be seen clearly.
