Characterization of the anticorrosive properties in bismuth-titanate films obtained by the sol-gel method
(Journal of Physics: Conference SeriesInglaterra, 2019-11-29)
Sol-gel synthesis has been used since 1950 to prepare oxides. The method is attractive because the processes of obtaining the oxides are developed at room temperature; products with high purity and homogeneity are obtained, ...

Brazil is one of the largest chicken meat producers and exporters in the world and this industry wastewater has a high pollutantload, mainly organic matter and nutrients content, which dischargecan ...
Diferenças nas respostas à sulfatação de óxidos e hidróxido de ferro (III) visando à extração seletiva de minérios estratégicos ricos em ferro
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2020-05-26)
Sulfation is a technique applied to the extraction of mineral commodities, such as rare earth, nickel, and titanium, as a preparation stage for leaching. Iron oxides and hydroxides are mineral constituents commonly present ...
Modulación de los mecanismos de respuesta a la escasez de hierro en Medicago truncatula mediada por rizobacterias promotoras del crecimiento vegetal
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-08)
Iron is an essential nutrient for plant growth. Is an element commonly found in an oxidized form, and therefore is very little available for plants. To contend with the deficiency, plants have developed mechanisms to acquire ...
Participación del sistema ISC en el daño oxidativo y la disfunción mitocondrial dependiente de Fe en Saccharomyces cerevisiae
(Universidad Michoacana de San Nicolás de Hidalgo, 2020-08)
Many proteins depend on cofactor molecules for its functionality. Cofactors can be either organic or inorganic compounds, covalently or non-covalently linked to specific sequence motifs. Hemo groups and the Fe-S centers ...
Efeito da suplementação de fonte inorgânica de ferro no desenvolvimento da glândula hipofaringeana de abelhas Apis mellifera L.
(Universidade Estadual Paulista (Unesp), 2018-07-16)
O ferro é um micro mineral importante para vários processos metabólicos, como transporte de oxigênio, manutenção do sistema metabólico, transferência de elétrons e síntese de DNA e RNA. O objetivo deste estudo foi suplementar ...
Synthesis, structural characterization and Mössbauer study of LnV 0.5Fe 0.5O 3 perovskites (Ln = Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Er)
(Pergamon-Elsevier Science Ltd, 2012-09)
Perovskites LnV 0.5Fe 0.5O 3 (Ln = Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Er) were synthesized by rapid solidification from arc-melted samples and characterized by the study of their crystal structure and hyperfine ...
Highly dispersed Fe3+-Al2O3 for the Fenton-like oxidation of phenol in a continuous up-flow fixed bed reactor. Enhancing catalyst stability through operating conditions
(Elsevier Science, 2018-12)
A highly dispersed Fe3+-Al2O3 catalyst (6 wt% Fe) was used for the catalytic wet hydrogen peroxide oxidation of phenol (1 g/L) in an up-flow fixed bed reactor (UFBR) under continuous operation. To enhance catalytic ...
