Photoluminescence emission at room temperature in zinc oxide nano-columns Abstract: Hydrothermal microwave method (HTMW) was used to synthesize crystalline zinc oxide (ZnO) nano-columns at the temperature of 120 °C with a soaking time of 8 min. […]
The influence of self-ordered TiO2 nanotubes microstructure towards Li+ intercalation Abstract: In this work, TiO2 nanotubes were prepared by anodization at a constant voltage in an electrolyte composed of fluoride species provided by ionic liquid (1 or 5 vol.%), applying 40 or 80 V. Different tube diameters […]
Ozone gas sensor based on nanocrystalline SrTi1-xFexO3 thin films Abstract: We report on the use of nanocrystalline SrTi1−xFexO3 (STF) for sensing ozone gas. Amorphous thin films were evaporated by the electron-beam physical vapor deposition technique and then converted to a polycrystalline form, as […]
Intrinsic magnetic properties of BixCo2−xMnO4 spinels obtained by short-time etching Abstract: We report the structural and magnetic properties of Co2MnO4, partially substituted by Bi at the octahedral site. Bismuth enhances ferromagnetism due to a decrease of the […]
Implementation of convective heating in Companhia Siderúrgica Nacional Blast Furnace runners Abstract: This paper describes the main characteristics and advantages of convective heating system for refractory lining, compared with conventional heating systems. In addition the main […]
Decay of photo-induced conductivity in Sb-doped SnO2 thin films, using monochromatic light of about bandgap energy Abstract: Doping tin dioxide (SnO2) with pentavalent Sb5+ ions leads to an enhancement in the electrical conductivity of this material, […]
Duas disciplinas de curta duração serão ministradas por pesquisadores do Centro de Desenvolvimento de Materiais Funcionais (CDMF) junto ao Programa de Pós-Graduação em Química da Universidade Federal de São Carlos (PPGQ – UFSCar). A primeira […]
Emerson Camargo, professor do Departamento de Química da Universidade Federal de São Carlos (DQ – UFSCar) e pesquisador do Centro de Desenvolvimento de Materiais Funcionais (CDMF), foi um dos palestrantes convidados no “II Workshop de […]
Far-infrared spectroscopic study of CeO2 nanocrystals Abstract: We present the far-infrared reflectivity spectra of 5 nm-sized pure and copper-doped Ce1−x Cu xO2−y (x = 0; 0.01 and 0.10) nanocrystals measured at room temperature in the 50–650 cm−1spectral range. Reflectivity spectra were analyzed using […]
Silver Molybdate and Silver Tungstate Nanocomposites with Enhanced Photoluminescence Abstract: Silver molybdate (Ag2MoO4) and silver tungstate (Ag2WO4) nanomaterials were prepared using two complementary methods, microwave assisted hydrothermal synthesis (MAH) (pH 7, 140 °C) and co-precipitation (pH […]
