Carboxylic acids and polyethylene glycol assisted synthesis of nanocrystalline nickel ferrites
(Elsevier Sci Ltd, Oxford, 2013)
Different synthesis methods for the preparation of nanocrystalline nickel ferrites are reported: the thermal decomposition of precursors, made of: (i) metal-nitrate salts with carboxylic acids (citric, malonic and tartaric), ...
Nondestructive evaluation of surface degradation of silicon carbide-cordierite ceramics subjected to the erosive wear
(Elsevier Sci Ltd, Oxford, 2013)
Covalent bond in SiC ceramic request high temperature for its sintering. In order to put down sintering temperature of SiC ceramics we choose cordierite as phase between SiC particles. Reactive sintering is an effective ...
Prediction of thermophysical and transport properties of ternary organic non-electrolyte systems including water by polynomials / Predskazivanje termofizičkih i transportnih svojstava trojnih organskih neelektrolitnih sistema, uključujući vodu, pomoću polinoma
(Serbian Chemical Society, Belgrade, 2013)
The description and prediction of thermophysical and transport properties of ternary organic non-electrolyte systems including water by polynomial equations are reviewed. Empirical equations of Radojković et al. (also known ...
Experimental and theoretical study of substituent effect on C-13 NMR chemical shifts of 5-arylidene-2,4-thiazolidinediones
(Elsevier, Amsterdam, 2013)
The electronic structure of 5-arylidene-2,4-thiazolidinediones has been studied by using experimental and theoretical methodology. The theoretical calculations of the investigated 5-arylidene-2,4-thiazolidinediones have ...
New facile one-pot synthesis of S-alkyl thiolcarbamates from xanthogenate in water
(Springer Wien, Wien, 2013)
A simple and efficient one-pot synthesis was developed for the preparation of S-alkyl thiolcarbamates from xanthogenate without catalyst using water as a solvent. The water can be recycled after removal of the product. The ...
Influence of chemical stress on sulfur-polymer composite structure
(New Developments in Polymer Composites Research, 2013)
Sulfur- polymer composites are high performance thermoplastic materials made of mineral aggregate, filler, and modified sulfur binder, instead of cement and water as in ordinary Portland cement- based composites at ...
Supercritical extraction of phloroglucinols from St. John's wort (Hypericum Perforatum L.) - Process optimization, mathematical modeling and antimicrobial activity
(Phytochemicals: Occurrence in Nature, Health Effects and Antioxidant Properties, 2013)
St. John's Wort (Hypericum perforatum L.) has been widely used as an anti-inflammatory and healing agent in traditional medicine. Some para-pharmaceutical products, prepared from the extract of St. John's Wort, are frequently ...
Volumetric Properties, Viscosities, and Refractive Indices of the Binary Systems 1-Butanol + PEG 200, + PEG 400, and + TEGDME
(Springer/Plenum Publishers, New York, 2013)
Densities, viscosities, and refractive indices of three binary systems consisting of 1-butanol with polyethylene glycols of different molecular weights (PEG 200 and PEG 400) or tetraethylene glycol dimethyl ether (TEGDME) ...
A solidification/stabilization process for wastewater treatment sludge from a primary copper smelter / Proces solidifikacije/stabilizacije za tretman otpadnih voda mulja iz primarne topionice bakra
(Serbian Chemical Society, Belgrade, 2013)
Wastewater treatment sludge from a primary copper smelter is characterized as hazardous waste that requires treatment prior to disposal due to its significant contents of heavy metals and arsenic. The aim of the presented ...
Structure-reactivity correlation for the kinetics of the formation reaction of 4-(substituted phenyl)-1,4-dihydropyridines / Korelacije strukture i reaktivnosti za kinetiku reakcije sinteze supstituisanih 4-fenil-1,4-dihidropiridina
(Serbian Chemical Society, Belgrade, 2013)
Quantitative structure-reactivity correlations for the kinetics of the Hantzsch synthesis of 4-(substituted phenyl)-1,4-dihydropyridines in the reaction between ethyl m- and p-substituted 2-benzylideneacetoacetate and the ...
