Additional information on elastomer and SAN microstmcture is provided by C-nmr analysis (100). Rubber particle composition may be inferred from glass-transition data provided by thermal or mechanochemical analysis. Rubber particle morphology as obtained by transmission or scanning electron microscopy (101) is indicative of the ABS manufacturing process (77). (See Figs. 1 and 2.)... 

The major gaseous components were analyzed by a gas chromatograph equipped with a TCD and a molecular sieve 13X column. The specific surface areas of carbon produced were measured by the BET method(ASAP 2010, Micromeritics). The morphology and particle size of the formed carbon were investigated by the scanning electron microscopy(S-4200, Hitachi... 

Particle morphology can be examined with optical microscopy and scanning electron microscopy. A discussion of both techniques is presented. 

Scanning electron microscopy is commonly used to study the particle morphology of pharmaceutical materials. Its use is somewhat limited because the information obtained is visual and descriptive, but usually not quantitative. When the scanning electron microscope is used in conjunction with other techniques, however, it becomes a powerful characterization tool for pharmaceutical materials. 

Various particle morphologies have been reported using scanning electron microscopy (SEM) [7,25,26]. The y-form can exhibit morphologies of dense irregularly shaped particles, or of needle-like particles that result in a more loose-knit matrix [7,25]. Instant sorbitol was found to be an...

Other advances in mesoscopic measurements include the application of magnetic resonance imaging (MRI) to study real-time hydrate growth from ice particles and water droplets, andparticle morphology (Moudrakovski et al., 2004). Scanning electron microscopy has also been shown to be a useful tool for studying natural...

Scanning electron microscopy was used to probe the film morphology of the two-stage latex particles. Figure 9A is a surface photograph of the 65//35 (St//BA) latex showing a uniform packing... 

The abrasivity of surfaces is related to the shape of surface profiles and can be described numerically. The morphology of wear particles, in terms of their shape, size, and surface texture, reflects the complex nature of the wear process involved in particle formation (Stachowiak, 1998 and 2000 Stachowiak and Podsiadlo, 1999 and 2001). The cumulative evaluation of turbine lubricating oil system, using techniques such as automatic particle counters, ferrography, ICP-AES spectroscopy, and scanning electron microscopy indicated the involvement of very small iron particles in the size range of 1-10 microns or less, and abrasive wear silica particles in the size range of 10-40 microns (Korycki and Wislicki, 1991). 

Scanning electron microscopy (SEM) can provide a wealth of information about particle morphology however, it is not well suited for quantitative image analysis.
