In situ influence of coal ash dump on the quality of neighboring surface and ground waters by applying correlation statistic analysis
(Elsevier, 2007)
The aim of this study was to establish the real in situ influence of coal ash and slag transport and storage on the quality of neighboring surface and ground waters by applying correlation statistic analysis. It was found ...
Electronic properties of environmental pollutants and their mutagenic activity: Nitro derivatives of azaphenanthrenes
(Oxford : Pergamon-Elsevier Science Ltd, 2015)
The physico-chemical properties of nitroazaphenanthrene isomers: 4-nitro-9-azaphenanthrene (4-N-9-Aph), 5-nitro-9-azaphenanthrene (5-N-9-Aph), 6-nitro-4-azaphenanthrene (6-N-4-Aph), 8-nitro-1-azaphenanthrene (8-N-1-Aph), ...
Regioselective synthesis of 1,3-thiazines by sequential 4-oxothiazolidine to 1,2-dithiole to 1,3-thiazine transformations: role of intramolecular non-bonded S/O interactions
(Elsevier, 2007)
A new synthetic approach to 2,3-dihydro-4H-1,3-thiazine derivatives based upon reductive rearrangement of 1,2-dithiole-3-ylidene thiones has been developed. In turn, the 1,2-dithiole derivatives were prepared by an efficient ...
Lossy gradient index transmission optics with arbitrary periodic permittivity and permeability and constant impedance throughout the structure
(IOP Publishing, 2012)
A remarkably simple exact analytical solution is obtained for the electromagnetic field distribution across infinite metamaterial-containing composites with any arbitrary periodic variation of complex effective permittivity ...
Electrooxidation of p-nitrophenol using a composite organo-smectite clay glassy carbon electrode
(Elsevier, 2014)
Bentonite clay rich in smectite clay mineral from seldom investigated locality Mecji Do (MD) in Serbia was modified. The organomodification was performed with different loadings of benzyltrimethylammonium (BTMA) cation. ...
Synthesis and characterization of self-assembled polyaniline nanotubes/silica nanocomposites
(American Chemical Society (ACS), 2009)
Self-assembled semiconducting, paramagnetic polyaniline nanotubes have been synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate in aqueous medium in the presence of colloidal silica particles ...
Biomimetic synthesis and properties of cellular SiC
(Elsevier Sci Ltd, Oxford, 2014)
Biomorphous beta-SiC ceramics were produced from several species of wood such as ash, wild cherry, black alder, Persian walnut, sessile oak and European hornbeam. The wood was pyrolysed, impregnated with tetraethyl ...
Antimalarial and antiproliferative evaluation of bis-steroidal tetraoxanes
(Elsevier, 2003)
Several cis and trans bis-steroidal 1,2,4,5-tetraoxanes possessing amide terminus were synthesised and evaluated as antimalarials and antiproliferatives. The compounds exhibited submicromolar antimalarial activity against ...
Correlation between structure, retention, property, and activity of biologically relevant 1,7-bis(aminoalkyl)diazachrysene derivatives
(Elsevier, 2013)
The physicochemical properties, retention parameters (R-M(0)), partition coefficients (log P-OW), and pK(a) values for a series of thirteen 1,7-bis(aminoalkyl) diazachrysene (1,7-DAAC) derivatives were determined in order ...
CO2 looping cycles with CaO-based sorbent pretreated in CO2 at high temperature
(Chemical Engineering Science, 2009)
In this study, pretreatment of CaO-based sorbent in a CO2 atmosphere at high temperature is investigated for its effect on CO2 capture. Three limestones from three widely different geographical locations are used for the ...
