Contrasting effect of silicon on iron, zinc and manganese status and accumulation of metal-mobilizing compounds in micronutrient-deficient cucumber
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2014)
Although the beneficial role of silicon (Si) in alleviation of abiotic stress is well established, little is known of the relevance of Si nutrition under microelement deficiency. The aim of our work was to investigate the ...
Raman Responses in Mechanically Activated BaTiO3
(Wiley, Hoboken, 2014)
The structure and lattice dynamics of mechanically activated BaTiO3 was investigated in this study. Phonon behavior and crystal structure stability of the obtained nanocrystalline BaTiO3 were discussed from the view point ...
Morphological and crystallographic characteristics of lead powder obtained by electrodeposition from an environmentally friendly electrolyte
(Elsevier Science Bv, Amsterdam, 2014)
Lead powder obtained by potentiostatic electrodeposition from alkaline electrolyte, based on hydroxide ions, was investigated. The shape of lead crystals strongly depends on overpotentials of electrodeposition. The regular ...
Novel simple methods for the synthesis of single-phase valentinite Sb2O3
(Springer, Dordrecht, 2014)
Several methods with solid and dissolved reactants were investigated as possible routes for synthesis of single-phase valentinite Sb2O3. The methods are based on simple chemical reaction between SbCl3 and NaOH. The method ...
Differential response of antioxidative systems of maize (Zea mays L.) roots cell walls to osmotic and heavy metal stress
(Wiley, Hoboken, 2014)
An analysis of peroxidase and ascorbate oxidase activity, phenolic content and antioxidant capacity of isolated maize root cell walls was performed in controls and plants stressed with polyethylene glycol (PEG) or heavy ...
Filter strip as a method of choice for apoplastic fluid extraction from maize roots
(Elsevier Ireland Ltd, Clare, 2014)
Apoplastic fluid was extracted from maize (Zea mays L) roots using two procedures: collection from the surface of intact plant roots by filter paper strips (AF) or vacuum infiltration and/or centrifugation from excised ...
Metals and electrolytes in sclerotic hippocampi in patients with drug-resistant mesial temporal lobe epilepsy
(Wiley-Blackwell, Hoboken, 2014)
An altered metal and electrolyte profile has been implicated in the pathologic mechanisms of chronic epilepsy; however, no study has comprehensively measured hippocampal concentrations of these elements in patients with ...
Comparative study of the genotoxic response of freshwater mussels Unio tumidus and Unio pictorum to environmental stress
(Springer, Dordrecht, 2014)
Genotoxic response of freshwater mussels U. tumidus and U. pictorum to environmental stress was studied using comet assay on hemocytes and gill cells. The mussels were acclimated to controlled laboratory conditions for 10 ...
Dielectric and magnetic properties of BaTiO3-NiFe2O4 multiferroic composites
(Elsevier Sci Ltd, Oxford, 2014)
Multiferroic composites with the general formula x BaTiO3-(1-x) NiFe2O4 (x=0.5, 0.7, 0.8) were prepared by mixing chemically obtained nickel ferrite and barium titanate powders. Optimum processing parameters for a reduction ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Elsevier Sci Ltd, Oxford, 2014)
Starting nanopowders of TiO2 (anatase 99.7%) and alpha-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750-1250 degrees C in air. Structural, morphological ...
