1. Encapsulating TiO2 into Polyvinyl Alcohol Coated Polyacrylonitrile Composite Beads for the Effective Removal of Methylene Blue
In this work, novel nanocomposite beads based on polyvinyl alcohol (PVA) coated polyacrylonitrile (PAN) with encapsulation of TiO2 nanoparticles (PPT) were developed successfully via a novel green synthetic method and its methylene blue (MB) removal ability by adsorption was also investigated. As-prepared nanocomposite beads were characterized by different t

2. Heterogeneous photo-Fenton and photocatalytic degradation studies of 2-chloro-4-nitrophenol (2Cl4NP) using foundry sand and TiO2 coated cement/clay beads
ABSTRACT Cement and clay beads coated with TiO2were used for the photo-degradation and mineralization of 2-chloro-4-nitrophenol (2Cl4NP) along with a heterogeneous solar photo-Fenton process using foundry sand (FS) as the iron source. The degradation process was optimized using slurry photocatalysis where 96% degradation of 2Cl4NP was achieved in 120 min at

3. Degradação fotocatalítica de tartrazina com TiO2 imobilizado em esferas de alginato
The potential of heterogeneous photocatalysis using TiO2 immobilized in alginate beads was evaluated for the degradation of tartrazine yellow azo dye. The treatment was performed under the action of a high-pressure mercury vapor lamp of 125 W and the degradation performance was investigated with the absorbance supplied by a photocolorimeter. Alginate beads w

4. Tartrazine degradation by supported TiO2on magnetic particles
ABSTRACTMagnetic beads were obtained by dropping a solution of sodium alginate containing magnetite particles into a CaCl2 solution. TiO2anatase particles were synthetized by a sol-gel method at low temperature (75 °C), and were supported on magnetic beads to obtain the magnetic photocatalyst, MC. Magnetite particles and magnetic photocatalyst were characte

5. Avaliação do processo de adsorção-fotodegradação com esferas de TiO2-quitosana para o tratamento de efluentes de indústria têxtil / Evaluation of the adsorption-photodegradation with chitosan-TiO2 beads for the treatment of effluents of textile industry
De maneira geral, as indústrias têxteis apresentam um elevado potencial poluente. As principais razões para essa poluição são a geração de elevados volumes de resíduos líquidos contendo alta carga orgânica e forte coloração derivada dos corantes. Entretanto, estes efluentes têxteis são possíveis de serem tratados por rotinas convencionais que

6. Alterations in Gene Expression in Human Mesothelial Cells Correlate with Mineral Pathogenicity
Human mesothelial cells (LP9/TERT-1) were exposed to low and high (15 and 75 μm2/cm2 dish) equal surface area concentrations of crocidolite asbestos, nonfibrous talc, fine titanium dioxide (TiO2), or glass beads for 8 or 24 hours. RNA was then isolated for Affymetrix microarrays, GeneSifter analysis and QRT-PCR. Gene changes by asbestos were concentration-
