Structural, morphological and catalytic characterization of neutral Ag salt of 12-tungstophosphoric acid: Influence of preparation conditions
(Elsevier, 2015)
The objective of this study is the structural and morphological characterization of the Ag3PW12O40 salts (AgWPA) of 12-tungstophosphoric acid (WPA) obtained under different preparation conditions and testing of their acid ...
Experimental investigation and thermodynamic prediction of the Cu-Sb-Zn phase diagram
(Elsevier, 2012)
Ternary Cu-Sb-Zn system has been thermodynamically assessed by using CALPHAD method and experimentally by DSC and SEM-EDS methods. The liquidus projection, invariant equilibria, several vertical sections and isothermal ...
Corrosion resistance of welded joints of X5CrNi18-10 stainless steel
(Elsevier, 2019)
This paper considers the influence of nitrogen in the shielding gas during TIG welding as well as the influence of a welding current level on the resistance to pitting corrosion and intergranular corrosion in welded joints ...
Nanoporous Network Channels from Self-Assembled Triblock Copolymer Supramolecules
(Wiley-V C H Verlag Gmbh, Weinheim, 2011)
Supramolecular complexes of a poly(tert-butoxystyrene)-block-polystyrene-block-poly(4-vinylpyridine) triblock copolymers and less than stoichiometric amounts of pentadecylphenol (PDP) are shown to self-assemble into a ...
Antioxidant Activity of Wines Determined by a Polarographic Assay Based on Hydrogen Peroxide Scavenge
(American Chemical Society (ACS), 2010)
Antioxidant (AO) activity of various red and white wines of different origin as well as some individual phenolic compounds present in wine has been assessed using a polarographic assay. Direct current polarography has been ...
Antioxidant activity of propolis extracts from Serbia: A polarographic approach
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Antioxidant activity (AO) of commercial propolis extracts (PEs), available on Serbian market, was determined by direct current (DC) polarography. Polarographic anodic current of 5.0 mmol L-1 alkaline solution of H2O2 was ...
Bacillus amyloliquefaciens laccase - From soil bacteria to recombinant enzyme for wastewater decolorization
(Elsevier Sci Ltd, Oxford, 2013)
One hundred wild type strains of Bacillus sp. were isolated from industrial and agricultural soil across Serbia and screened for laccase activity. Three strains showed high laccase activity temperature optimum of 65 and ...
Electrochemical activity of iron in acid treated bentonite and influence of added nickel
(Elsevier, 2015)
Bentonite originated from Macji Do, Serbia, was submitted to acid treatment at 70 degrees C for 30 min, while only the concentration of applied HCl varied. The obtained acid treated samples were used to modify glassy carbon ...
Chemical Composition of Two Different Extracts of Berries Harvested in Serbia
(American Chemical Society (ACS), 2013)
Total phenolic content (TPC), total anthocyanin content (TAC), free and total ellagic acid content, sugars, minerals, and radical scavenging activity were determined in nine berries harvested in Serbia. More than 30 phenolic ...
Electrochemical versus Spectrophotometric Assessment of Antioxidant Activity of Hop (Humulus lupulus L.) Products and Individual Compounds
(American Chemical Society (ACS), 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 ...
