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 ...
Synthesis and deposition of ZnO based particles by aerosol spray pyrolysis
(Elsevier Science Sa, Lausanne, 1997)
Spray pyrolysis was used for the deposition of well defined submicronic to nanosize particles based on ZnO. The influence of the temperature in the range from 345 to 1165 K, solution concentration (0.004 and 1.5 mol dm(-3)) ...
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. ...
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 ...
Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Elsevier Science Sa, Lausanne, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
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 ...
Microstructural characterization of mechanically activated ZnO-Cr2O3 system
(Elsevier Sci Ltd, Oxford, 2005)
An equimolar mixtures of starting ZnO and Cr2O3 powders were mechanically activated by grinding using a planetary ball mill for various periods of time (40-320min). Formation of nanocrystalline ZnCr2O4 as normal spine] ...
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 ...
UV-irradiation provokes generation of superoxide on cell wall polygalacturonic acid
(Wiley, Hoboken, 2013)
We examined the redox effects of UV irradiation on cell wall isolates from Pisum sativum leaves, and polygalacturonic and galacturonic acid, in the presence of hydrogen peroxide. For this purpose, electron paramagnetic ...
