Influência do suporte e método de preparação na atividade de catalisadores para...
Silva, Fernando Alves daHydrogen production from sources that contain in their molecular matrix (hydrocarbons and alcohols) to use in fuel cells has intensified the search for active and selective catalysts for the conversion to H2. Copper and nickel based in different supports has shown promise for it. Zeolites, niobium and silica were evaluated in the ethanol steam reforming to produce hydrogen energy. The reaction routes were stron...
The representation of feminine in the amazon mitopoese
Silva, Fernando Alves da; Simões, Maria do Perpétuo Socorro GalvãoThis article aims to analyze the character of a mythical Amazon oral narrative from her imaginary and symbolic construction.

Effects of coconut granular activated carbon pretreatment on membrane filtratio...
Silva, Flávia Vieira da; Yamaguchi, Natália Ueda; Lovato, Gilselaine Afonso; Silva, Fernando Alves da; Reis, Miria Hespanhol MirandaThis study evaluates the performance of a polymeric microfiltration membrane, as well as its combination with a coconut granular activated carbon (GAC) pretreatment, in a gravitational filtration module, to improve the quality of water destined to human consumption. The proposed membrane and adsorbent were thoroughly characterized using instrumental techniques, such as contact angle, Brunauer–Emmett–Teller) and...
