?The nodular eutectic in the austenitebainite steel is pseudoeutectic of austenite and (Fe,Mn)3C, which is formed between austenite dendrites at the end of the solidification because of the segregation of C and Mn. By calculation of thermodynamics, analysis of twodimensional lattice misfitting calculation and observations of TEM and SEM, it is found that CeO2 and CeAlO3 may act as the heterogeneous nuclei of the nodular eutectic.

Using close-packed colloidal crystals-silica as the template, a novel 3D well-ordered and long-ranged periodic macroporous material MnO_2 has been prepared by colloidal crystals template methods. The prepared product has been characterized by means of X-ray diffraction (XRD) and scanning electron micrography (SEM). The X-ray diffraction displays that the phase of MnO_2 is tetragonal, and the scanning electron micrography shows that MnO_2 replicates the structure of the started template and exhibits 3D long-range...

Using close-packed colloidal crystals-silica as the template, a novel 3D well-ordered and long-ranged periodic macroporous material MnO_2 has been prepared by colloidal crystals template methods. The prepared product has been characterized by means of X-ray diffraction (XRD) and scanning electron micrography (SEM). The X-ray diffraction displays that the phase of MnO_2 is tetragonal, and the scanning electron micrography shows that MnO_2 replicates the structure of the started template and exhibits 3D long-range ordered honeycomb framework. The process of preparing the 3D order macroporous MnO_2 was discussed. The effect of the infiltration times to the final morphology of MnO_2 was studied and an abnormity existed in the shrinkage of the final outcome.
