The nanorods are composed of a bundle of 20 nm wide whiskers, which are composed of spherical nanoparticles(\{5 nm\}). It is suggested that the co-operation of the reduction of Co 2+ and the transition from spherical \{micelles\} into hexagonal rod-like micelles lead to the formation of the nanostructured cobalt filaments.展开更多

The mechanism of the morphology transformation of CaCO 3 from calcite to vaterite with the increase of polar group content in latex was investigated. The concentrating effect of calcium ions on the latex surface inhibited the transformation from vaterite to calcite.展开更多
