1. Synthesis of ZnO Nanoparticles by the Sol-Gel Protein Route: A Viable and Efficient Method for Photocatalytic Degradation of Methylene Blue and Ibuprofen
The photocatalytic degradation of methylene blue dye and ibuprofen drug was studied in the presence of zinc oxide, synthetized by the protein sol-gel route. The catalyst, calcined at 1000 ºC, presented a tendentious morphology to filaments characteristic of ZnO crystalline, characterized by X-ray diffraction (XRD) and confirmed by the presence of Zn energy

3. Caracterização de filmes nanocompósitos biodegradáveis a base de gelatina produzidos com um aplicador automático de filmes / Characterization of gelatin-based biodegradable nanocomposite films produced using an automatic film spreader
O desenvolvimento de filmes à base de biopolímeros tem sido bastante estudado devido aos problemas ambientais causados pelas embalagens de plásticos sintéticos. Dentre os biopolímeros, merece destaque a gelatina, que tem excelente propriedade filmogênica. Entretanto, até o presente momento, os filmes de gelatina apresentam limitações de propriedades

4. CARACTERIZAÇÃO ELÉTRICA E DIELÉTRICA DE CERÂMICAS DE BATIO3 E BA0,77CA0,23TIO3 SINTETIZADAS PELO MÉTODO SOL GEL PROTEICO. / CHARACTERIZATION OF ELECTRICAL AND DIELECTRIC CERAMICS OF BATIO3 E BA0, 77CA0, 23TIO3 SYNTHESIZED BY SOL GEL METHOD PROTEIN.
Materiais cerâmicos a base de titanato de bário (BaTiO3 BT Barium Titanate) possuem uma larga aplicação industrial como Capacitores Cerâmicos Multicamadas (MLCCs Multi layers ceramic capacitors) devido, principalmente, a sua alta constante dielétrica e boa estabilidade da capacitância com a variação da temperatura, porém esse material apresenta tam

5. ExpressÃo de uma quitinase de Chromobacterium Violaceum em Pichia Pastoris: purificaÃÃo e caracterizaÃÃo parcial da proteÃna recombinante / Expression of a chitinase from Chromobacterium Violaceum in Pichia pastoris: purification and partial characterization of recombinant protein
A utilizaÃÃo de microrganismos como sistemas heterÃlogos de expressÃo de proteÃnas tem se mostrado uma estratÃgia alternativa e/ou complementar aos passos tradicionais utilizados no processo de purificaÃÃo de proteÃnas. Diante deste contexto, quitinases (EC 3.2.1.14), enzimas hidrolÃticas capazes de degradar quitina, tÃm sido expressas em diferent

6. âNova rota de sÃntese de nanopartÃculas de NiMn2O4 usando o MÃtodo Sol-Gel ProtÃicoâ / "New route of synthesis nanoparticles NiMn2O4 method using sol-gel protein."
This work presents a new route for the synthesis of nickel manganate (NiMn2O4) through the sol-gel protein method, using gelatin as an organic precursor. The synthesis of nanoparticles was performed by dilution of inorganic salts (NiCl2.6H2O, MnCl2.4H2O) and gelatin in distilled water with the addition of sodium hydroxide (NaOH). This solution was then place

7. Transição sol-gel em soluções orgânico-aquosas de lisozima e o efeito indutor do solvente: caracterização cinética e estrutural / Sol-gel transition in aqueous-organic solutions of lysozyme and the solvent-inducing effect: a kinetic and structural characterization
Lysozyme sol-gel transition in tetramethylurea/water was investigated in depth. These dispersions produced highly viscous systems, which evolved to physical gels, i.e., systems where the gel backbone is maintained by van der Walls forces and hydrogen bonding. The work was conducted in two fronts: a) the study of lysozyme dispersions in binary mixtures; b) th

8. Expressão de fatores de regulação miogenica e metaloproteinases no musculo estriado esqueletico de ratos com insuficiencia cardiaca / Myogenic regulatory factors and metalloproteinase expression in rat skeletal muscle with heart failure
Background: Heart failure (HF) is associated with a skeletal muscle myopathy with increased expression of fast myosin heavy chains (MHC) and extracellular matrix (ECM) alterations. The skeletal muscle-specific molecular regulatory mechanisms controlling MHC expression during HF have not been described. Myogenic regulatory factors (MRF), a family of transcrip

9. Scanning electron microscopy study of protein immobilized on SIO2 Sol-gel surfaces
Uniform attachment of enzymes to solid surfaces is essential in the development of bio and optical sensor devices. Immobilization by adsorption according to hydrophilic or hydrophobic nature is dependent on the charges and defects of the support surfaces. Sol-gel SiO2 densified glass surfaces, frequently used as supports for protein immobilization, are evalu

10. Desenvolvimento de sistemas enzimÃticos (lipases) para aplicaÃÃo na hidrÃlise e sÃntese de Ãsteres
A commercial lipase from Mucor miehei was immobilized onto different supports, nylon, nylon-polyvinyl alcohol (nylon-PVA) and polysiloxane-polyvinyl alcohol magnetic particles (POS-PVA), and were tested for hydrolytic activity. Lipase-POS/PVA was the immobilized system with higher operational stability, so their apparent Km and Vmax, optimum temperature and

11. Preparo e caracterização de microcapsulas obtidas por polimerização ionica para alimentação de larvas de peixe / Preparation and characterization of microcapsules obtained by polymerization Ionica feeding of fish larvae
This research aimed at producing microcapsules capable of retaining proteins, with the objective of substituting the live organisms used in larval fish feed. Four different polysaccharides: alginate, carrageenan, gelan gum and pectin were used, all having the capacity to form gels by ionic polymerization both individually and in association, in order to prod

12. Binding and release of iron by gel-encapsulated human transferrin: Evidence for a conformational search
Human transferrin is a single-chain bilobal protein with each of the two similar but not identical lobes in turn composed of two domains. Each lobe may assume one of two stable structural conformations, open or closed, determined by a rigid rotation of the domains with respect to each other. In solution, the transformation of a lobe between open and closed c
