Yabuta et al. (2003) prepared porous Ormosil-type hybrids through a sol-gel process, where the pores are introduced by sucrose particles as the template. The porosity of the hybrids is about 90%, almost independent of the ratio TEOS/ PDMS. Scanning electron micrograph analysis indicates the hybrids contain pores with 300-500 ixm and 10-50 Apatite is deposited on the large pore walls of the Ca-containing hybrids within 3 days when the hybrids are soaked in SBF. [Pg.1723]

Figure C2.17.6. Transmission electron micrograph and its Fourier transfonn for a TiC nanocrystal. High-resolution images of nanocrystals can be used to identify crystal stmctures. In tliis case, tire image of a nanocrystal of titanium carbide (right) was Fourier transfonned to produce tire pattern on tire left. From an analysis of tire spot geometry and spacing, one can detennine that tire nanocrystal is oriented witli its 11001 zone axis parallel to tire viewing direction [217]. Figure C2.17.6.

Scanning electron micrographs of fracture surfaces revealed the presence of both amorphous and crystalline phases which corresponded to results from XRD analysis (Figure 6.12). What is of interest is that the crystalline phase is MgHP04.3H20 and not Mg(H2P04)2.2H2O or... [Pg.233]

Auger specimens 10 x 2 x 1 mm were heat-treated and then notched to control the location of fracture. Two of these notched samples at a time were loaded into specimen grips such that they could be broken independently under UHV and then examined by a SAM instrument. Scanning electron micrographs allowed different grain boundaries and transgranular cleavage areas to be selected for analysis. [Pg.179]

Electron Microprobe Measurements. Compositional information regarding transpoirt 6T nickel and vanadium in the catalysts uppermost 10,000A surface layers was obtained from electron microprobe analysis of the samples. Scanning electron micrographs and x-ray spectra were obtained with a JEOL 733 scanning electron... [Pg.163]

The chemical and physical properties of ribosomes are well characterized (for reviews see The exact understanding of their function, however, still lacks a detailed molecular model. Appropriate methods such as image reconstruction from electron micrographs of two-dimensional sheets, or X-ray structure analysis, all depend on the crystallizability of the material. [Pg.58]
