Pilhas a combustível de óxido sólido: materiais, componentes e configurações

Química Nova (2007)

Roberto Salgado Amado Luiz Fernando B. Malta Francisco Manoel dos Santos Garrido Marta Eloísa Medeiros

In this paper the current status of fuel cells is described with particular emphasis on high (T > 800 o C) and intermediate (T < 800 o C) temperature solid oxide fuel cells.Also the importance of the fuel cell technology is shown.Reviewed are the fundamental features, the basic principles, types of fuel cell, fabrication methods, cell configurations and the development of components (cathodes, anodes, electrolytes, interconnect) and materials.

BENEFICIAMENTO E CARACTERIZAÇÃO DE QUARTZO PARA OBTENÇÃO DE SILÍCIO GRAU METALÚRGICO

Holos (2012)

Lívia Gonçalves Leida Soares Fernanda Arruda Nogueira Gomes da Silva Francisco Manoel dos Santos Garrido Fernanda Arruda Nogueira Gomes da Silva Roberto Salgado Amado

Este trabalho descreve as etapas de caracterização e purificação de quartzo para obtenção de um silício grau metalúrgico (SiGM) com baixo nível de impurezas. A amostra de quartzo, após as etapas de britagem, calcinação seguida de quenching e moagem autógena apresentou um teor de SiO2 de 99,5%, isto é, um aumento de aproximadamente 2% em relação a amostra original. A análise granulométrica indicou que a fração abaixo de 37 µm, correspondente a apenas 2,06% da amostra total, apresenta alto teor de impurezas, podendo ser removida, facilitando assim os ensaios de purificação. O estudo demonstrou que a amostra de quartzo beneficiada apresenta um potencial uso à produção de SiGM.

Jorge Amado e o romance de 1930: protagonismo de uma nova voz emergente (1931-1934)

Roberto Salgado Amado

Jorge Amado's literary activity, manifested in books or articles in the first half of the 1930's, reveals the protagonist of a new voice that emerges with the purpose to promote deep transformations in the Brazilian literature practiced at that time.Environments, characters, language and narratives emerge throughout this period as a new Brazilian literature, corroborated by the growing interest of the readers' choice and the development of a flourishing editorial industry.Political and social environmentrepresented in Brazilian context by the 1930 Revolution and its consequences and, atthe international level, by inter-war tensions -forge favorable conditions for the manifestation of this new voice through which Jorge Amado practices, defines and defends his transforming project, in line with his generation of authors, represented by the social romance, intentional romance and proletarian romance -similar labels for the same proposal.

trans-Bis(2,2′-bipyridine-4,4′-dicarboxylic acid-κ² N,N′)dichloridoruthenium(III) perchlorate

IUCrData (2018)

Lívia Gonçalves Leida Soares Diego S. Padilha Roberto Salgado Amado Marciela Scarpellini

In the crystal structure of the ruthenium(III) complex, trans -[Ru III (dcbpy) 2 Cl 2 ]ClO 4 (dcbpy = 2,2′-bipyridine-4,4′-dicarboxylic acid, C 12 H 8 N 2 O 4 ), the Ru III atom lies on an inversion centre, showing a small distortion in its octahedral environment. The Ru—Cl bond lengths are shorter than those present in the analogous trans -ruthenium(II) compound containing the bipyridine ligand. The C—O distances in the two symmetry-independent carboxylic acid moieties of the ligand are similar in one group, but different in the other. This is probably due to the different intermolecular interactions they experience with neighbouring cationic complexes. The hydrogen-bonding interactions in which they are involved form a three-dimensional structure, similar to those found in coordination polymers.

Determinação de glicerol livre e total em amostras de biodiesel por método enzimático com detecção colorimétrica

Química Nova (2012)

Higor da Cal Valdez Roberto Salgado Amado Flávia C. de Souza Eliane D’Elia Eduardo de Castro Vieira

ENZYMATIC METHOD WITH COLORIMETRIC DETECTION.A method based on enzymatic activities was developed using three enzymes (glycerokinase, glycerol-3-phosphate oxidase and peroxidase) and colorimetric detection for the determination of glycerol in biodiesel.The enzymatic conversion of glycerol produces H 2 O 2 that is eliminated by the action of peroxidase, an oxygen acceptor and 4-aminoantipirine, producing water and a colored compound, which was analyzed.This method showed good linear correlation coefficient (r = 0.9937) in the concentration range of 4.95 x 10 -5 to 3.96 x 10 -4 % (w/w) and had experimental limits of detection and quantitation of 7.10 x 10 -6 and 2.10 x 10 -5 % (w/w), respectively.
