Chemometrics in biomonitoring: Distribution and correlation of trace elements in tree leaves
(Elsevier, Amsterdam, 2016)
The concentrations of 15 elements were measured in the leaf samples of Aesculus hippocastanum, Tilia spp., Betula pendula and Acer platanoides collected in May and September of 2014 from four different locations in Belgrade, ...
Silicon increases phosphorus (P) uptake by wheat under low P acid soil conditions
(Springer, Dordrecht, 2017)
Although silicon (Si) is known to improve plant growth under low phosphorus (P) conditions, the in planta mechanisms responsible for this effect are still unknown. Here, we investigated the role of Si on P uptake along ...
Extracellular iron diminishes anticancer effects of vitamin C: An in vitro study
(Nature Publishing Group, London, 2014)
In vitro studies have shown that hydrogen peroxide (H2O2) produced by high-concentration ascorbate and cell culture medium iron efficiently kills cancer cells. This provided the rationale for clinical trials of high-dose ...
Stability, characterization and functionality of proton conducting NiO-BaCe0.85-xNbxY0.15O3-delta cermet anodes for IT-SOFC application
(Elsevier Science Sa, Lausanne, 2014)
There are many of properties of anodes based on proton conductors, like microstructure, conductivity and chemical stability, which should be optimized. In this work we were dealing with the influence of niobium on the ...
Improved electrical properties of Nb doped BaCe0.9Y0.1O2.95 electrolyte for intermediate temperature SOFCs obtained by autocombustion method
(Elsevier Science Sa, Lausanne, 2014)
Nb doped BaCe0.9Y0.1O2.95 (BCY) powders were synthesized by both solid state reaction (SSR) and autocombustion reaction (ACR) method to investigate how different synthesis routes influence the properties of the powders and ...
Use of histopathology and elemental accumulation in different organs of two benthophagous fish species as indicators of river pollution
(Wiley, Hoboken, 2015)
The bottom feeding fish species have a good potential to be used for assessments of pollution, as they are under pressure from pollutants from both water and sediments. In this study, the level of similarity of histopathological ...
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 ...
Decalcification resistance of alkali-activated slag
(Elsevier Science Bv, Amsterdam, 2012)
This paper analyses the effects of decalcification in concentrated 6 M NH4NO3 solution on mechanical and microstructural properties of alkali-activated slag (AAS). Portland-slag cement (CEM II/A-S 42.5 N) was used as a ...
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 ...
Risk assessment of using fish from different types of reservoirs as human food - A study on European perch (Perca fluviatilis)
(Elsevier Sci Ltd, Oxford, 2020)
Concentrations of As, Cd, Cr, Cu, Hg, Pb, and Zn in sediment samples and muscle tissue of the European perch were analyzed using inductively-coupled plasma optical emission spectrometry (ICP-OES), with the aim to assess ...
