Antioxidant Activity and Total Phenolic Content in Some Cereals and Legumes
(Taylor & Francis Inc, Philadelphia, 2011)
The antioxidant activities and total phenolic content of 4 cereals (buckwheat, wheat germ, barley, and rye) and 4 legume seeds (lentils, mungo bean, red kidney bean, and soy bean) were determined. The total phenolic content ...
Improvement of chemical control in the water-steam cycle of thermal power plants
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
A more effective chemical control in the water-steam cycle (WSC) of thermal power plants (TPP) is proposed in this paper. Minimization of corrosion effects by the production of ultra pure water and its strict control is ...
Isopiestic determination of the osmotic and activity coefficients of the {yKCl + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
The osmotic coefficients of aqueous mixtures of KCl and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method over the range of ionic strengths from (2.3700 to 11.250) mol . kg(-1) ...
Complexation of amidated pectin with poly(itaconic acid) as a polycarboxylic polymer model compound
(Elsevier Sci Ltd, Oxford, 2011)
Complexes based on amidated pectin (AP) and poly(itaconic acid) (PIA) were prepared by casting films from solutions of AP and PIA in different ratios with the pectin amount ranging from 10% to 90% by mass. The complexes ...
Electrochemical characterization of polyaniline electrode in ammonium citrate containing electrolyte
(Elsevier Science Sa, Lausanne, 2011)
Polyaniline electrode (PANI) was formed electrochemically at graphite electrode. Electrochemical polymerization was performed at constant current density of 2.0 mA cm(-2) from aqueous solution of 1.0 mol dm(-3) HCl with ...
Hydrogenated hydroxyapatite materials with improved biocompatibility
(24th European Conference on Biomaterials, EBS 2011, 2011)
On the zinc sorption by the Serbian natural clinoptilolite and the disinfecting ability and phosphate affinity of the exhausted sorbent
(Elsevier, Amsterdam, 2011)
The Serbian natural zeolite is moderately effective in removing the zinc(II) ions from aqueous solutions. At 298 K the sorption capacity varies from 13 to 26% for the initial Zn(II) solution concentration of 100 and 600 ...
Synthesis of N-(3-and 4-substituted phenyl)-O-isobutyl thionocarbamates from O-isobutyl xanthate and amines using a nano-platinum multi-walled carbon nanotube catalyst
(Springer Wien, Wien, 2011)
Twelve N-(3- and 4-substituted phenyl)-O-isobutyl thionocarbamates, eight of which are novel, were synthesized from O-isobutyl xanthate and 3- and 4-substituted anilines in the presence of a nano-platinum aminophenyl ...
Optimization of integrated steel plant recycling: Fine-grain remains and by-products synergy
(Strojarstvo, 2011)
The recycling capabilities of the integrated steel plant (capacity 2 million tons/year), have been evaluated annually. The quantities of dusts, scales and sludge generated at the Steel Plant located in Smederevo, Serbia, ...
Swelling, Mechanical and Antimicrobial Studies of Ag/P(HEMA/IA)/PVP Semi-IPN Hybrid Hydrogels
(Polish Acad Sciences Inst Physics, Warsaw, 2011)
A simple and fast approach to the design and production of new hybrid polymeric biomaterials with silver particles is presented in this work. Silver/semi-interpenetrating network hybrid hydrogels (Ag/semi-IPNHHs) were ...
