Tailoring the ferroelectric and magnetic properties of Bi5Ti3FeO15 ceramics by doping with Co and Y
(Elsevier Masson s.r.l., 2022)
The ferroelectric and magnetic properties of four-layered Aurivillius Bi5Ti3FeO15 (BFT) compounds via partial substitution of Bi3+ with Y3+ and Fe3+ with Co2+ (according to formula: Bi5-xYxTi3FeO15, x = 0.1, 0.2, 0.3; ...
Application of pulsating overpotential regime on the formation of copper deposits in the range of hydrogen co-deposition
(Springer, New York, 2010)
Electrodeposition of copper by pulsating overpotential (PO) regime in the range of hydrogen co-deposition was examined by scanning electron microscopy. It was found that the increase of the pause-to-pulse ratio produced a ...
Variations in polyamine conjugates in maize (Zea mays L.) seeds contaminated with aflatoxin B1: a dose-response relationship
(Wiley, Hoboken, 2020)
BACKGROUND Cereal seeds, such as maize seeds, are frequently contaminated with aflatoxin B1 (AFB1), one of the most dangerous naturally occurring carcinogens. In plants, phenolamides are involved in biotic stress response. ...
Nature of structural changes in LSM-YSZ nanocomposite material during thermal treatments
(Elsevier Science Sa, Lausanne, 2004)
Nanocomposite powders in the system (La1-xSx)(a)MnO3-YSZ((1-y)) [LSM-YSZ], as an attractive cathode material for high operating solid oxide fuel cell (SOFC), were obtained through ultrasonic spray pyrolysis (1.7 MHz) method. ...
The influence of mechanical activation on the stoichiometry and defect structure of a sintered ZnO-Cr2O3 system
(Trans Tech Publications Ltd, 2004)
Mixtures of starting ZnO and Cr2O3 powders in equimolar quantities were mechanically activated by grinding using a high energy vibro-mill for 0, 40 and 80 minutes. Qualitative X-ray diffraction analysis made after sintering ...
Application of the general theory of disperse deposits formation in an investigation of mechanism of zinc electrodeposition from the alkaline electrolytes
(Elsevier Science Sa, Lausanne, 2017)
In this study, mechanism of electrodeposition of zinc from the alkaline electrolytes has been investigated using the general theory of disperse deposits formation. The exchange current densities in the range 18.4-88 mA ...
Preparation of nanostructured Zn-Cr-O spinel powders by ultrasonic spray pyrolysis
(Elsevier Sci Ltd, Oxford, 2001)
Ultrasonic spray pyrolysis (1.7 MHz) has been applied for the generation of zinc chromium oxide submicronic (470 nm) particles from the corresponding metal nitrate solution. Heterogeneous gas-liquid/solid chemical reactions ...
Variability Estimation of the Protein and Phenol Total Content in Honey Using Front Face Fluorescence Spectroscopy Coupled with MCR-ALS Analysis
(Springer, New York, 2019)
It has been explored to what extent the ratio of the two main fluorophores in honey, originating from proteins and phenolic compounds, change between the honey extraction stage and packaging in the jars. Fluorescence ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Elsevier Science Sa, Lausanne, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
Effect of the anodic current density on copper electrodeposition in the hydrogen co-deposition range by the reversing current (RC) regime
(Elsevier Science Sa, Lausanne, 2011)
In this study, the effect of the anodic current density in the regime of reversing current (RC) on the quantity of evolved hydrogen and morphology of copper deposits was considered. The quantity of evolved hydrogen was ...
