Figure C2.17.3. Close-packed array of sub-micrometre silica nanoparticles. Wlren nanoparticles are very monodisperse, they will spontaneously arrange into hexagonal close-packed stmcture. This scanning electron micrograph shows an example of this for very monodisperse silica nanoparticles of -250 nm diameter, prepared in a thin-film fonnat following the teclmiques outlined in [236].

Iridium Oxide. Iridium dioxide [12030 9-8] coatings, typically used in combination with valve metal oxides, are quite similar in stmcture to those of mthenium dioxide coatings. X-ray diffraction shows the mtile crystal stmcture of the iridium dioxide scanning electron micrographs show the micro-cracked surface typical of these thermally prepared oxide coatings.

In order to determine whether the new nanotubule electrode shows improved performance, a control electrode composed of the same material but prepared via a more conventional method is required. This control LiMn204 electrode was prepared by applying the precursor solutions described above directly onto a 1 cm Pt plate and thermally processing as before. Scanning electron micrographs showed that these films consisted of LiMn204 particles with diameters of —500 nm [124]. Spectrophotomet-ric assay showed that this control electrode also contained 0.75 mg of LiMn204 per cml A polypyrrole coat identical to that applied to the tubular electrode (0.065 mg) was also applied to this control electrode. 

Scanning electron micrographs showing the particle morphology of as-received constituents and milled (NaBH -i- MgH ) composites with low (10-50 wt%) content of MgH are presented in Fig. 3.40. The particles of as-received NaBH and MgH powders have irregular shape and average size 145 and 36 pm, respectively (Fig. 3.40a, b).

Laboratory experiments of longer duration confirmed the model prediction. Figure 5 is made of scanning electron micrographs showing the surface condition after 10, 30, 120, and 600 days at 50 °C. The crystals gradually become covered by a deposit and are entirely masked after 600 days. Transmission electron microscope examination of an ultramicrotome cross-section of the layer formed after 600 days shows (1) exfoliation of the outer hydrotalcite...

Removal of about half of the linear polymer by solvent extraction left individual zeolite crystals containing the remaining polymer. Scanning electron micrographs showed there was essentially no polymer between or on the zeolite (observable before the extraction), and resembled micrographs of the pure zeolite. All linear polymer could be removed on extended solvent extraction.
