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 ...
Component analysis of the fluorescence spectra of a lignin model compound
(Elsevier Science Sa, Lausanne, 2006)
In order to test whether lignin fluorescence originates from discrete fluorophores, fluorescence emission spectra of the lignin model dehydrogenative polymer (DHP) were analyzed by the band deconvolution method and ...
Annual variation of proteins and phenols in honey of a bee society using fluorescence spectroscopy: a way to assess effects of antivarroa treatments on honey composition
(Springer, New York, 2020)
Proteins and phenols are minor, but important components of honey. Phenols originate from nectar and proteins from nectar/pollen and bees themselves. These two types of compounds are important for growth and development ...
Pyrosol preparation and structural characterization of SnO2 thin films
(Elsevier Science Sa, Lausanne, 2003)
Polycrystalline tin oxide thin films were prepared from ethanol solution Of SnCl2.H2O (concentrations: 0.05, 0.1, 0.2 and 0.4 mol/dm(3)) at different substrate temperatures ranging from 300 to 450 degreesC. The kinetic ...
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 ...
A new insight into the mechanism of lead electrodeposition: Ohmic-diffusion control of the electrodeposition process
(Elsevier Science Sa, Lausanne, 2013)
A new insight into the mechanism of lead electrodeposition from nitrate solutions is presented by analysis of the polarization characteristics and by scanning electron microscopic (SEM) analysis of the surface morphology ...
Humidity sensing potential of Fe2TiO5-pseudobrookite
(Springer, Dordrecht, 2018)
Bulk samples of pseudobrookite with an orthorhombic crystal structure were prepared by sintering a mixture of starting hematite and anatase nano powders in the weight ratio 60:40 at three different sintering temperatures ...
Correlate between morphology of powder particles obtained by the different regimes of electrolysis and the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2012)
Morphologies of copper powder particles obtained by both potentiostatic and pulsating overpotential (PO) regimes of electrolysis were investigated by the technique of scanning electron microscopy (SEM). Particles of dendritic ...
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 ...
