Rod-like morphology

Ti-6.6Al-3.5Zr-1.3Si-l.lB. In as-cast state, as-dendritic structure is practically invisible. Lamellar a -structure of matrix is recognized well. Close to uniformly distributed borides have rod-like morphology and fogged like brushwood. Thickness of rods is between 0.1-1.5 pm. Their length is up to 0.2 mm. Fine (0.1-0.3 pm) silicides are uniformly distributed along matrix. Fracture feature is intensive cleavage microcracking of RT and... 

The rod-like morphology of the nanofibrils supports the high yields, because a-chitin nanofibrils prepared by acid hydrolysis from TEMPO-mediated oxidation have a spindle-like shape and a larger distribution range of widths. 

Furthermore, R. K. Rana et al. reported a bio-inspired assembly of Ag/ AgCl/ZnO nanostructures with poly(allylaminehydrochloride) as the mineralizer for the enhaneed visible-light-driven photocatalytic activity. The as-prepared Ag/AgCl/ZnO had a spindle- and rod-like morphology along the (OOOl)direction with a width of 100-200 nm and a length of 400-700 nm (Fig. 26A). The Ag/AgCl particles were trapped in the porous... 

Rod-like morphology has also been reported for gold nanoparticles [232]. It has been shown that in partial agreement with Pileni s work discussed above, increase in water/surfactant ratio could increase the percentage of rod-like particles, though in a limited way. In addition, other factors like reactant ratio have been considered to influence the morphology. 

Fibres of poly(A-vinyl carbazole)with a high modulus have been prepared by melt extrusion. They have a highly ordered one dimensional rod-like morphology with a hexagonal unit cell, a = b = c— 1.23 nm. 

Several polymer systems have been successfully analysed by equation (2) and meaningful rate and energetic parameters determined (from the temperature dependence). Liquid-induced crystallization, with acetone and chloroform, of polycarbonate s develops as spherulites for which n = 3.0 over the temperature of crystallization range 561—586 K. Cellulosealso crystallizes from solution but with a rod-like morphology, for which = 1.0 these differences may reflect differences in chain flexibility.
