The scaffolds and nanoparticles were qualifyed utilizing ICP-AES, FT-IR, XRD, TGA, TEM, BET, SEM, and EDS methods. Selenium of SAPO-34 and nanoparticles were investigated by varietys on the physicochemical holdings of scaffolds admiting swelling ratio, density, porosity, bio-degradation, mechanical behavior, and biomineralization. Cell viability, cell adhesion and cytotoxicity of Ca-SAPO-34/CS and Fe-Ca-SAPO-34 scaffolds were inquired by MTT assay and SEM on h-DPSCs which exposed cell proliferation no toxicity on scaffolds. Cell tests marched that Ca-SAPO-34/CS scaffold clearly displayed a positive effect on differentiation of hDPSCs into osteogenic/odontogenic cells and moderate effect on cell proliferation the incorporation of Fe(2)O(3) to Ca-SAPO-34/CS scaffold raised the proliferation of hDPSCs and osteogenic differentiation. Alizarin red, Alkaline phosphatase and QRT-PCR consequences evinced that Fe-Ca-debased SAPO-34/CS can lead to osteoblast/odontoblast differentiation in DPSCs through the up-regulation of related cistrons, thus pointing that Fe-Ca-SAPO-34/CS has remarkable outlooks as a biomaterial for hard tissue engineering.Preparation and Characterization of a Novel Sulfonated Titanium Oxide Incorporated Chitosan Nanocomposite Membranes for Fuel Cell Application. In this study, nano-TiO(2) sulfonated with 1,3-propane sultone (STiO(2)) was incorporated into the chitosan (CS) matrix for the preparation of CS/STiO(2) nanocomposite membranes for fuel cell coatings. The grafting of sulfonic acid (-SO(3)H) groupings was supported by Fourier transform infrared spectroscopy, thermogravimetric analysis and energy-dispersive X-ray spectroscopy. The physicochemical dimensions of these prepared membranes, such as water uptake, intumescing ratio, thermal and mechanical stability, ion exchange capacity and proton conductivity, were determined. The proton conducting groups on the surface of nano-TiO(2) can form continuous proton conducting tracts along the CS/STiO(2) interface and thus improve the proton conductivity of CS/STiO(2) nanocomposite membranes. The CS/STiO(2) nanocomposite membrane with 5 wt% of sulfonated TiO(2) indicated a proton conductivity (0 S·cm(-1)) equal to that of commercial Nafion 117 membrane (0 S·cm(-1)). The thermal and mechanical stability of the nanocomposite membranes were meliorated because the interfacial interaction between the -SO(3)H group of TiO(2) and the -NH(2) group of CS can restrict the mobility of CS concatenations to enhance the thermal and mechanical stability of the nanocomposite membranes. These CS/STiO(2) nanocomposite membranes have promising applications in proton exchange membrane fuel cellphones. Preparation of Chitosan/Calcium Alginate/Bentonite Composite Hydrogel and Its Heavy Metal Ions Adsorption Properties.In order to avoid the secondary pollution of the toxic residue of chemical crosslinking agent companioned by chemical hydrogel adsorbent and enhance the adsorption performance of physical hydrogel, chitosan/calcium alginate/bentonite (CTS/CA/BT) composite physical hydrogel was fabricated. The formation mechanism and structure of the composite hydrogel were learned by FTIR, XRD and SEM. Adsorption operations of the hydrogel toward Pb(2+), Cu(2+) and Cd(2+) in water under different condition as well as multi-ion competitive sorption were enquired. The adsorption procedures were named with the canonical adsorption kinetics and isotherms models. With the utilization of XPS analysis and adsorption thermodynamics analysis, it was seed that the adsorptions were spontaneous physico-chemical adsorptions. The results showed that the maximum adsorption capacity of the hydrogel for Pb(2+), Cu(2+) and Cd(2+) strived up to 434, 115 and 102 mg·g(-1), respectively, better than those of other physical hydrogels or chitosan/bentonite composite the composite hydrogel improved the collectability of bentonite and showed a good reusability.
