It is revealed that a certain amount of excessive formamide is favorable for preparation of the aerogel with high porosity, while more excessive glycol can deteriorate the formation of nano-porous SiO2 aerogel network. Additionally, the pH value of the reaction system has a strong impact on the microstructure and properties of prepared SiO2 aerogel.

Due to their applications in magnetic, optical, electronic and catalyst, polynuclear lanthanide clusters are of importance. In this part, a series of nanowheel-shaped nonanuclear lanthanide clusters,〓〓(Ln=Sm~Tm; BA=benzoylacetone), were prepared and characterized. Each complex can exist in three phases, i. e., cubic, tetragonal and triclinic.

Discussion on membrane formation mechanismBased on the Flory-Huggins theory, Phase equilibrium equations of PVDF/DMAc/water ternary system were wrote out, and the binodal and spinodal lines in the phase diagrams of the system were obtained via numerical calculation. Combined the kinetic description and the thermodynamic phase diagram, membrane formation process were analyzed, which prepared the theoretical foundation for the further membrane formation mechanism research.
