The styrene-acrylate spheres were coated with the TiO2 colloidal particles via electrostatic effect and hydrogen bond interactions with the increase of aging time, thus the film-forming capability of the solution was changed. The poor film-forming capability results in the formation of the porous structure with dense, homogeneous island morphology. Then the TiO2 porous films with dense pores can be obtained after two coating-dissolving cycles.

Results:(1) CBC possesses a natural trabecular structure. Its components is similar to the mineral of bone.(2) CBC has great cellur biocompatibility. It can promote cell adhesion, proliferation and secretory while needn t modification.(3) In nude mice, the ectopic osteogenesis of MCCAB was obvious which was better than that of CBC alone and the new bone formation increased in pace with time. In the MCCAB, both intramembranous and cartilaginous osteogeneses were seen but the former dominated.(4) When MCCAB was autotransplanted intramuscularly, the osteogenesis was much better than that of negative control groups.(5) The MCCAB can repair autogenous calvaria defects effectively and the effect was much better than that of CBM alone and blank group. Conclusion:(1) CBC possesses good biocompatibility, osteoconduction and porous structure, can be used as scaffold material for constructing of tissue engineering bone.

Finally, the article discussed the possible mechanism of multi-phase electrochemical degradation of wastewater through the XPS spectrum of the used catalysts surface: In the acid solutions, the electro-generated O_2 may get electrons on the porous graphite cathode and then form H_2O_2, H_2O_2 may diffused to the surface of catalyst and reacted with its active part to produce OH, which in turn can destruct organics. The catalyst functioned as both the catalyst to decompose H_2O_2 and the flocculants to sedimentate the degraded waste.

In chapter 4, the plane-radial and plane-parallel flows for Newtonian fluid in fractal porous media are analyzed. Based on the same assumption as that in chapter 3, the expressions for porosity, flow rate, velocity and permeability for both radial and parallel flows are developed. The proposed expressions are expressed as a function of tortuosity, fractal dimension, maximum and minimum pore diameters, and there are no empirical constant and every parameter has clear physical meaning in the proposed expressions.
