ABSTRACTThe various polymorphs of titanium oxide (TiO2) are probably the most widely studied materials for photovoltaic applications. It is well known that composition and particles size can have a profound effect on photoactivity. It is thought that high surface to volume nanostructures such as nanofibers and nanorods may possess the optimal properties. We have developed technology for the preparation of TiO2 nanofibers in a variety of forms including core shell structures, papers and films. The formation of mesoporous TiO2 fibers as spider webs and papers has been achieved by electrostatic deposition. The mesoporous fibers and other forms such as shaped particles and films have been employed as templates to grow TiO2 nanofibers in various configurations. The proposed research below will address the synthesis and characterization of the TiO2 fibers developed by these techniques

Pulsatilla chinensis (Bunge) Regel is a traditional Chinese medicine used to treat ulcerative colitis. This study prepared and characterized colon-targeted particles of P. chinensis saponins by particle design. Most of the P. chinensis saponins in the composite particles were coated with Eudragit S100, as seen in SEM micrographs; meanwhile, the characteristic diffraction peaks in X-RD, surface wettability, and particle size distribution of the composite particles were basically the same as those of Eudragit S100. These results suggested that the mechanochemical process could be used to prepare colon-targeted particles with core-shell structures with the drug coated by the excipient; the results also showed similar surface characteristics in the coating.
