Enhancement in statistical and image analysis for in situ mu SXRF studies of elemental distribution and co-localization, using Dioscorea balcanica
(Wiley-Blackwell, Hoboken, 2013)
Synchrotron-based X-ray microfluorescence (mu SXRF) is an analytical method suitable for in situ investigation of the distribution of micronutrient and macronutrient elements in several-micrometres-thick unstained biological ...
Magnetic properties of NiMn2O4-delta (nickel manganite): Multiple magnetic phase transitions and exchange bias effect
(Elsevier Science Sa, Lausanne, 2014)
We present magnetic properties of NiMn2O4-delta (nickel manganite) which was synthesized by complex polymerization synthesis method followed by successive heat treatment and final calcinations in air at 1200 degrees C. The ...
Interactions between (+)-Catechin and Quercetin during Their Oxidation by Nitrite under the Conditions Simulating the Stomach
(Amer Chemical Soc, Washington, 2014)
When foods that contain catechins and quercetin glycosides are ingested, quercetin glycosides are hydrolyzed to quercetin during mastication by hydrolytic enzymes derived from oral bacteria and the generated quercetin ...
The impact of in vivo and in vitro exposure to base analogue 5-FU on the level of DNA damage in haemocytes of freshwater mussels Unio pictorum and Unio tumidus
(Elsevier Sci Ltd, Oxford, 2014)
The impact of in vivo and in vitro exposure to anticancer drug 5-Fluorouracil (5-FU) on the level of DNA damage was evaluated using comet assay on haemocytes of freshwater mussels Unio pictorum and Unio tumidus. For the ...
Influence of the indium concentration on microstructural and electrical properties of proton conducting NiO-BaCe0.9-xInxY0.1O3-delta cermet anodes for IT-SOFC application
(Elsevier Science Sa, Lausanne, 2013)
Optimization of the major properties of anodes based on proton conductors, such as microstructure, conductivity and chemical stability, is yet to be achieved. In this study we investigated the influence of indium on the ...
Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramics
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
Silicon ameliorates manganese toxicity in cucumber by decreasing hydroxyl radical accumulation in the leaf apoplast
(Oxford Univ Press, Oxford, 2012)
This work was focused on the role of silicon (Si) in amelioration of manganese (Mn) toxicity caused by elevated production of hydroxyl radicals (center dot OH) in the leaf apoplast of cucumber (Cucumis sativus L.). The ...
Linking oxidative and salinity stress tolerance in barley: can root antioxidant enzyme activity be used as a measure of stress tolerance?
(Springer, Dordrecht, 2013)
A causal relationship between salinity and oxidative stress tolerance and a suitability of using root antioxidant activity as a biochemical marker for salinity tolerance in barley was investigated. Net ion fluxes were ...
Ultra-high breakdown field varistors prepared from individually synthesized nanoprecursors
(Elsevier Sci Ltd, Oxford, 2015)
Previously synthesized nanocrystalline ZnO doped with cobalt and manganese, Bi2O3 and Sb2O3 were the precursors for high voltage varistors preparation. Varistor ceramics were sintered at 750 degrees C, 770 degrees C or 900 ...
The assessment of soil availability and wheat grain status of zinc and iron in Serbia: Implications for human nutrition
(Elsevier, Amsterdam, 2016)
The deficiency of zinc (Zn) and iron (Fe) is a global issue causing not only considerable yield losses of food crops but also serious health problems. We have analysed Zn and Fe concentrations in the grains of two bread ...
