Prevention of Trace and Major Element Leaching from Coal Combustion Products by Hydrothermally-Treated Coal Ash
(Taylor & Francis Inc, Philadelphia, 2009)
The most important structural components of coal ash obtained by coal combustion in "Nikola Tesla A" power plant located near Belgrade (Serbia) are amorphous alumosilicate, alpha-quartz, and mullite. The phase composition ...
Double Palladium-Catalyzed Synthesis of Azepines
(Georg Thieme Verlag Kg, Stuttgart, 2013)
The synthesis of new 5H-pyridobenzazepine and 5H-dipyridoazepine compounds using as key step a palladium-catalyzed amination-cyclization reaction is reported. By choosing an appropriate combination of ligands and reactants ...
Study of ellagic acid electro-oxidation mechanism
(Springer Wien, Wien, 2013)
Ellagic acid is a biologically active polyphenol found in numerous fruits and vegetables. However, not many papers dealing with the electrochemical properties and protolytic equilibria of ellagic acid have been published ...
Density functional theory study of the multimode Jahn-Teller problem in the fullerene anion
(Wiley-Blackwell, Hoboken, 2013)
The fullerene anion, C60, within the Ih point group, is a spherical molecule subject to the T circle times h JahnTeller (JT) distortion. The descent in symmetry goes to the three epikernel subgroups, namely D5d, D3d, and ...
Bromophilic substitution/carbophilic substitution cascade reactions of alpha,alpha-dibromo-2-methoxyacetophenone with C-, N- and O-nucleophiles
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
alpha,alpha-Dibromo-2-methoxyacetophenone reacts, under mild reaction conditions, with C-, N- and O-nucleophiles via a bromophilic substitution/protonation/carbophilic substitution cascade process to afford alpha-monosub ...
Hydrothermal Transformation of Sawdust into Synthetic Coke-Mechanism and Influence of Experimental Parameters
(Taylor & Francis Inc, Philadelphia, 2009)
The influence of temperature, pressure, and time of interaction on the yield, caloric power, and elemental composition of solid product of hydrothermal transformation of sawdust into synthetic coke has been studied. With ...
Distribution and availability of potentially toxic metals in soil in central area of Belgrade, Serbia
(Springer Heidelberg, Heidelberg, 2010)
Belgrade, capital city of Serbia, has over 1,600,000 inhabitants and over 400,000 vehicles trafficking every day on its streets. The investigation of soil pollution was performed by sequential extraction analysis to ...
Influence of natural zeolitic tuff and organozeolites surface charge on sorption of ionizable fumonisin B-1
(Elsevier Science Bv, Amsterdam, 2010)
Natural Zeolitic tuff was modified with 2, 5 and 10 mmol M+/100 g of octadecyldimethylbenzyl ammonium (ODMBA) ions and the products were denoted as OZ-2, OZ-5 and OZ-10. The starting material and organozeolites were ...
Flow cytometry-based ultra-high-throughput screening assay for cellulase activity
(Academic Press Inc Elsevier Science, San Diego, 2013)
We have developed a novel, ultra-high-throughput screening assay for the detection of cellulase activity based on fluorescence-activated cell sorting (FACS) and double emulsion technology. Cellulase activity is detected ...
Molecular and cytogenetic changes in multi-drug resistant cancer cells and their influence on new compounds testing
(Springer, New York, 2013)
Multi-drug resistance (MDR) is a major obstacle to successful cancer treatment. Therefore, in vitro models are necessary for the investigation of the phenotypic changes provoked by cytotoxic agents and more importantly for ...
