Analysis of isothermal sintering of zinc-titanate doped with MgO
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
Investigation of zinc stannate synthesis using photoacoustic spectroscopy
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
Mixtures of ZnO and SnO2 powders, with molar ratio of 2:1, were mechanically activated for 40, 80 and 160 minutes in a planetary ball mill. The resulting powders were compacted into pellets and non-isothermally sintered ...
Aerosol Deposition of Ba0.8Sr0.2TiO3 Thin Films
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2009)
In this work we optimized conditions for aerosol deposition of homogeneous, nano-grained, smooth Ba0.8Sr0.2TiO3 thin films. Investigation involved optimization of deposition parameters, namely deposition time and temperature ...
Antioxidant Properties of Phenolics in Castanea sativa Mill. Extracts
(University of Zagreb, 2009)
Using electron paramagnetic resonance (EPR) spectroscopy, antioxidant properties of chestnut extracts have been investigated as a source of phenolic compounds. In addition to their high antioxidant activities against ...
Inferring the extinction of species known only from a single specimen
(Cambridge Univ Press, New York, 2020)
Many species are poorly known, with the sum of our knowledge represented by specimens in museums. For assessment of conservation status the most enigmatic and challenging species are probably those known only from a single ...
Oxidative status of maternal blood in pregnancies burdened by inherited thrombophilias
(Public Library Science, San Francisco, 2020)
Oxidative status of maternal blood represents an important parameter of pregnancy that is involved in both, regulation of physiological processes and (if significantly altered) development of different pregnancy complications. ...
The impact of different extracts of six Lamiaceae species on deleterious effects of oxidative stress assessed in acellular, prokaryotic and eukaryotic models in vitro
(Elsevier, Amsterdam, 2020)
The main objective of this research was to evaluate the impact of methanolic, ethanolic and aqueous extracts of Origanum majorana L., Origanum vulgare L., Teucrium chamaedrys L., Teucrium montanum L., Thymus serpyllum L. ...
Silicon acquisition and accumulation in plant and its significance for agriculture
(Elsevier Sci Ltd, Oxford, 2018)
Although silicon (Si) is ubiquitous in soil and plant, evidence is still lacking that Si is essential for higher plants. However, it has been well documented that Si is beneficial for healthy growth of many plant species. ...
Effects of strontium doping on microstructure and functional properties of solution-derived potassium sodium niobate thin films
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2020)
The effects of strontium doping (0-2 mol%) on structure, microstructure and functional properties of potassium sodium niobate (KNN) thin films deposited on Pt(111)/TiOy/SiO2/Si substrates were investigated. Incorporation ...
Macronutrient contents in the leaves and fruits of red raspberry as affected by liming in an extremely acid soil
(Czech Academy Agricultural Sciences, Prague, 2015)
The study evaluates the effect of liming materials application in combination with NPK fertilizer and borax on macronutrient contents (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg)), in an ...
