Synthesis, characterization and electrocatalytical behavior of Nb-TiO2/Pt nanocatalyst for oxygen reduction reaction
(Elsevier Science Bv, Amsterdam, 2010)
In order to point out the effect of the support to the catalyst for oxygen reduction reaction nano-crystalline Nb-doped TiO2 was synthesized through a modified sol-gel route procedure. The specific surface area of the ...
Decline in the Index of Biotic Integrity of the Fish Assemblage as a Response to Reservoir Aging
(Springer, Dordrecht, 2009)
The fish assemblage from reservoir Medjuvrsje was monitored over the 1955-2000 period. The Medjuvrsje Reservoir is one of the oldest Serbian reservoirs formed in 1953. Ichthyofauna was sampled in 1955, 1984, 1991 and 2000. ...
Multiferroic bismuth manganite prepared by mechanochemical synthesis
(Elsevier Sci Ltd, Oxford, 2010)
Multiferroic bismuth manganite (BiMnO3) is known as a material that exhibits both ferromagnetic and ferroelectric properties making it interesting for various technological applications. Unfortunately, preparation of BiMnO3 ...
Synthesis and characterization Pt nanocatalysts on tungsten based supports for oxygen reduction reaction
(Elsevier Science Bv, Amsterdam, 2012)
Platinum nanocatalysts on two tungsten based supports have been synthesized and characterized as catalysts for oxygen reduction reaction in 0.5 mol dm(-3) HClO4 solution, at 25 degrees C. Tungsten based support assigned ...
Generation of Hydroxyl Radical in Isolated Pea Root Cell Wall, and the Role of Cell Wall-Bound Peroxidase, Mn-SOD and Phenolics in Their Production
(Oxford Univ Press, Oxford, 2009)
The hydroxyl radical produced in the apoplast has been demonstrated to facilitate cell wall loosening during cell elongation. Cell wall-bound peroxidases (PODs) have been implicated in hydroxyl radical formation. For this ...
Structure study of nanosized La- and Sb-doped BaTiO3
(Elsevier Science Sa, Lausanne, 2010)
Lanthanum and antimony doped barium titanate powders were prepared by polymeric precursors method through Pechini process. Obtained powder was pressed into pellet and sintering was performed at 1300 degrees C for 8 h. The ...
Cell wall-bound cationic and anionic class III isoperoxidases of pea root: biochemical characterization and function in root growth
(Oxford Univ Press, Oxford, 2012)
Cell wall isolated from pea roots was used to separate and characterize two fractions possessing class III peroxidase activity: (i) ionically bound proteins and (ii) covalently bound proteins. Modified SDS-PAGE separated ...
Free radicals and antioxidants at a glance using EPR spectroscopy
(Taylor & Francis Ltd, Abingdon, 2011)
The delicate balance between the advantageous and detrimental effects of free radicals is one of the important aspects of human (patho)physiology. The controlled production of reactive oxygen and nitrogen species has an ...
Electrochemical versus Spectrophotometric Assessment of Antioxidant Activity of Hop (Humulus lupulus L.) Products and Individual Compounds
(Amer Chemical Soc, Washington, 2013)
Antioxidant (AO) activity of extracts of hop cones (Serbian domestic varieties) and commercial hop products (Saaz, Spalter, Spalter select, and Magnum pellets) was determined by parallel application of recently developed ...
Leaf vitamin C contents modulate plant defense transcripts and regulate genes that control development through hormone signaling
(Amer Soc Plant Biologists, Rockville, 2003)
Vitamin C deficiency in the Arabidopsis mutant vtc1 causes slow growth and late flowering. This is not attributable to changes in photosynthesis or increased oxidative stress. We have used the vtc1 mutant to provide a ...
