Morphology shape

The infrared spectra demonstrate that there is a strong interaction between CR and the PS segment of SBS and between SBS and BR. Scanning electron micrographs of the fracture surfaces further support the conclusion. The fracture surface of 70 30 BR/CR shows layer-shaped morphology and 30 70 blends show hillock-shaped protmsions. Addition of 5% SBS reduces the particle size, makes the particles more spherical, and enhances uniform distribution. This provides further evidence of the compatibilizing effect of SBS.

In the case of extended chain crystals, we showed that a single crystal is easily formed even for Mn higher than 105. An ECSC shows a cigar-like and tapered shape morphology, observed by polarizing optical microscopy [22] and by transmission electron microscopy [48]. 

Chandra and Avedisian 411] studied the collision dynamics of a liquid (n-heptane) droplet on a polished, solid, stainless steel surface, and on a liquid film created by deposition of a preceding droplet using a flash photographic method. They presented a comprehensive series of clear images of droplet shape, morphology, and structure during the deformation process. In their experiments, the...

AFM studies clearly verified these results. The surface of the GaSb film deposited at 500 °C as shown in Figs. 16a and 16b is very homogeneous. At higher magnification, the cubic-shaped morphology of single crystallites can clearly be observed. 

Cultured BHK cells that had heen maintained in a medium containing tunicamycin still shed various membrane glycoproteins into the medium,539 and this is in keeping with observations mentioned in Section IV,4. However, the proportion of fibronectin found in the medium appeared to he lessened.540-541 Cells kept in the presence of tunicamycin showed profound morphological changes, from epitheloid to elongated, spindle-shaped morphology, and lowered adhesion to the substratum.

The solid-state properties like crystallinity, polymorphism (crystal structure), shape (morphology), and particle size of drugs are important in the stability, dissolution, and processibility of drugs. Some commonly used methods in solid-state studies include microscopy, hot stage microscopy with polarized light, x-ray powder diffraction (XRPD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), Fourier transform infrared FTIR/Raman, and solid-state NMR.

Serdyuchenko (1933), McConnell (1954), and Ross (1960) have reported analyses of Cr-rich clays ranges from 1 to 15% (Table XL1). Some of the clays are formed by ground water alteration of serpentine and probably volcanic material. It is questionable if any of the samples are pure. McConnell s (1954) material has a lath-shaped morphology. Chukhrov and Anosov (1950) described a copper-bearing (20.96%) montmorillonite from the oxidized zone of weathered sulfide ores (Table XLI). Spangenberg (1938) described a nickel-rich montmorillonite. 

Electron microscopic examination of catalyst materials, particularly those containing natural components, permits the identification of their origin. For example, carbons utilized as supports for precious metals in a wide variety of slurry-phase and fixed-bed reactions can be derived from a large number of naturally occurring sources (Fig. 8). The shape, morphology, and composition are useful properties for determining their origin. 

As-synthesized Na-ZSM-5, which possesses an isostructure with TPA-ZSM-5, exhibits a hexagonal-lath-shaped morphology. Liquid phase Sil /A Oo ratio is important in controlling the formation of Na-ZSM-5 and mordenite, and the silica source influences the liquid phase composition. High yield of Na-ZSM-5 is obtained only when a small-sized silica sol is employed. A linear relationship between Na/Al starting atomic ratio and the nucleation rate indicates that charge neutralization of SBU is required for zeolite crystallization. 

The physical parameters for the metallic effect, which influence the ratio between reflection and scattering and thereby the flop effect, the lightness and brightness, the brilliance and sparkle, the gloss and the distinctiveness of image (DOI) etc. etc. can simply be described in terms of particle size, particle shape (morphology), particle size distribution and particle orientation in the film...
