ZnO varistors from intensively milled powders
(Elsevier Sci Ltd, Oxford, 2007)
Two ways of application of intensive milling in ZnO varistors processing were compared. First was intensive milling of mixture of previously prepared constituent phases. In this case, intensive milling was applied only to ...
Silicon modifies leaf nutriome and improves growth of oak seedlings exposed to phosphorus deficiency and Phytophthora plurivora infection
(Frontiers, 2023)
Beneficial effects of silicon (Si) on plants have primarily been studied in crop species under single stress. Moreover, nutrient acquisition-based responses to combination of biotic and abiotic stresses (a common situation ...
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] ...
Fingerprint detection and using intercalated CdSe nanoparticles on non-porous surfaces
(Elsevier, Amsterdam, 2014)
A fluorescent nanocomposite based on the inclusion of CdSe quantum dots in porous phosphate heterostructures, functionalized with amino groups (PPH-NH2"CdSe), was synthesized, characterized and used for fingerprint detection. ...
Biological activity of essential oils of Athamanta haynaldii and Myristica fragrans to gypsy moth larvae
(Industrial Crops and ProductsElsevierElsevier, 2013)
Ethanol solutions of essential oils obtained from Athmanta haynaldii and Myristica fragrans were tested for their toxicity and antifeedant activity against the second instar gypsy moth larvae in the laboratory bioassay. ...
The nature of structural changes in nanocrystalline ZnO powders under linear heating conditions
(Elsevier Sci Ltd, Oxford, 2004)
The nature of exothermal and irreversible structural changes observed during linear heating of nanocrystalline ZnO powders was investigated using differential scanning calorimetry, X ray, SEM and TEM analysis. Nanocrystalline ...
The effects of the pause to pulse ratio in the regime of pulsating overpotential on the formation of honeycomb-like structures
(Elsevier Science Inc, New York, 2009)
The formation of honeycomb-like structures in the pulsating overpotential (PO) regime was examined by scanning electron microscopy (SEM). The honeycomb-like structures obtained with a square-wave PO of different pause to ...
