K- and Cu-doped CaTiO3-based nanostructured hollow spheres as alternative catalysts to produce fatty acid ethyl esters as potential biodiesel
(Elsevier, 2020-04-12)
New functional polycation oxide-type catalysts were synthesized by the ultrasonic spray-pyrolysis method. The catalytic activity in the production of fatty acid ethyl esters (FAEE´s) using soybean oil was studied. Catalysts ...

Formation of localized magnetic states in graphene in hollow-site adsorbed adatoms
(Academic Press Ltd - Elsevier Science Ltd, 2018-01)
By applying tight binding model of adatoms in graphene, we study theoretically the localized aspects of the interaction between transition metal atoms and graphene. Considering the electron-electron interaction by adding ...
Validação da técnica de macacos planos na avaliação da resistência de alvenaria existente executada com blocos vazados de concreto
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2020-08-27)
The flat jack method is used as non-destructive test, on site, on masonry structures to obtain more accurate data. This method is already standardized internationally by ASTM and RILEM, however, the studies, standards, and ...
Diretrizes para práticas de qualidade nas diferentes etapas do processo de produção de lajes alveolares de concreto protendido
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Civil - PPGECivCâmpus São Carlos, 2015-02-11)
Industrialization in the Brazilian construction industry is a growing trend, while the need to fulfill tight deadlines increases as well as labor costs, being mandatory to keep quality standards and the competitiveness of ...
Estruturas ocas de TiO2 para fotodegradação de azul de metileno no espectro de luz visível.
(Universidade Estadual Paulista (Unesp), 2019-12-20)
A aceleração induzida das reações de superfície em fotocatalisador pela luz visível, é um fator crucial para melhorar a separação das reações redox e, assim, aumentar o desempenho do fotocatalisador. No entanto, a preparação ...
