Síntese e caracterização de tungstato de ferro (FeWO4) e tungstato de zinco (ZnWO4) para aplicações tecnológicas
(Universidade Federal de Santa MariaBREngenharia de ProcessosUFSMPrograma de Pós-Graduação em Engenharia de Processos, 2015-08-07)
In this study, two tungsten-based oxides, iron tungstate (FeWO4) and zinc tungstate
(ZnWO4), were synthesized by the routes microwave-assisted hydrothermal and
solvo-hidrothermal, respectively. The iron tungstate oxide ...
One-step hydrothermal synthesis and photocatalytic performance of ZnWO4/Bi2WO6 composite photocatalysts for efficient degradation of acetaldehyde under UV light irradiation
(Elsevier Science Bv, 2013-04)
Bi2WO6 with different Bi3+ ion concentrations (0?30 mol%) is incorporated with the ZnWO4 photocatalyst to improve the photocatalytic efficiency by forming a ZnWO4/Bi2WO6 composite photocatalyst with hierarchical heterostructure ...
Cytotoxicity of Portland Cement with Different Radiopacifying Agents: A Cell Death Study
(Elsevier B.V., 2011-02-01)
Introduction: The aim of this study was to investigate the cytotoxicity of white Portland cement (PC) alone or associated with bismuth oxide (PCBi), zirconium oxide (PCZir), and calcium tungstate (PCCa) in 2 cell lineages. ...
