1. Influence of Supporting Electrolytes on RO 16 Dye Electrochemical Oxidation Using Boron Doped Diamond Electrodes
The influence of different supporting electrolytes as well as of different current densities on RO16 dye electrochemical oxidation using BDD electrodes has been systematically studied. The RO16 azo-dye electrooxidation experiments were performed at different current densities and three different supporting electrolytes: H2SO4 0.1 mol L-1, HClO4 0.1 mol L-1 a

2. Nanocompósitos semicondutores ZnO/TiO2: testes fotocatalíticos
Titanium dioxide is an efficient photocatalist, being possible to improve its efficiency with better charge separation which occurs when it is coupled with other semiconductors. Nanometric particles of ZnO were used to impregnate TiO2 P25 in order to optimize its photocatalytic properties. ZnO/TiO2 composites were obtained at different proportions and were c

3. Hidrolases e fenoloxidases de microrganismos como marcadores para seleção de biosuplementadores e avaliação do tratamento sobre efluentes sucroalcooleiros
Due to the current and future problematic of the maintenance of the hydric resources, the reuse of waters after previous treatment has been a strategy in the management of aquifers. The bioaugmentation is one of the techniques of purification of effluents and, because of this, studies were carried out in lagoons from the station of treatment of effluents (ST

4. Study of photoinduced birefrigence, in layer-by-layer films containing azopolymer and azodye / Estudo de birrefrigência fotoinduzida em filmes automontados de azopolímeros e azocorantes
This work was aimed at investigating the influence of the molecular architecture and film fabrication on the photoinduced birefi-ingence of layer-by-layer (LbL) films containing the azopolymer PS 119® or the azodye Brylliant Yellow (BY) as photoreactive materials. The LbL films were produced with six polications, viz.: poly(allylamine hydrochloride) (PAH),

5. Polymeric nanocomposites containing azodyes, phthalocyanines and luminescent polymers / Compósitos poliméricos nanoestruturados de azocorantes,ftalocianinas e polímeros luminescentes
This thesis describes the fabrication and possible applications of layer-by-Iayer (LBL) nanostructured films for three distinct systems comprising i) azopolymers and azodyes, ii) organometallic molecules (phthalocyanines) and iii) luminescent polymers and azodyes. Optically induced birefringence and surface relief gratings (SRGs) were studied in the azobenze

6. Brownian ratchets and the photoalignment of liquid crystals
Molecular motors play key roles in areas ranging from biological transport to emerging nanotechnology. They produce current as a result of transfer of energy but not of momentum from a source; many molecular motor scenarios are based on the translational Brownian ratchet mechanism. Here we consider the mechanism of photoalignment of liquid crystals both in t

7. Purification and partial characterization of an elastolytic serine protease of Prevotella intermedia.
Elastolytic strains of Prevotella intermedia were isolated from pus samples of adult periodontal lesions. Elastase was found to associate with envelope, and it could be solubilized with guanidine-HCl. The enzyme was purified to homogeneity by sequential procedures including ion-exchange chromatography, gel filtration, and hydrophobic interaction chromatograp

8. Target polypeptide of a carcinogen is associated with normal mitosis and carcinogen-induced hyperplasias in adult hepatocytes.
Normal rat liver cytosol was found previously to contain a 14,000-dalton polypeptide that is the principal target of the carcinogen N-2-fluorenylacetamide (2-acetyl-aminofluorene) early during hepatocarcinogenesis. By using antiserum that identifies the 14,000-dalton polypeptide in liver cytosol, an immunologically related 17,500-dalton polypeptide was shown
