Composition of the Defensive Secretion in Three Species of European Millipedes
(Springer, Dordrecht, 2011)
Three European julid species, Cylindroiulus boleti, Leptoiulus trilineatus, and Megaphyllum bosniense, secrete mixtures of up to 12 different quinones. The major components in these species are 2-methoxy-3-methyl-1,4-benzoquinone ...
Defensive Secretions in Callipodella fasciata (LATZEL, 1882; Diplopoda, Callipodida, Schizopetalidae)
(Wiley-V C H Verlag Gmbh, Weinheim, 2011)
The small millipede Callipodella fasciata secretes an earthy smell when disturbed. This secretion was obtained by CH2Cl2 extraction from specimens of both sexes and was identified by GC/MS analyses to be composed of p-cresol ...
Water/Aromatic Parallel Alignment Interactions. Significant Interactions at Large Horizontal Displacements
(American Chemical Society (ACS), 2011)
Analysis of crystal structures from the Cambridge Structural Database (CSD) and high level ab initio calculations reveals that the water/aromatic parallel alignment interactions; where the water molecule or one of its 0 H ...
An Insight into Fatty Acid Composition of Calliergonella cuspidata
(Asian Journal Of Chemistry, Sahibabad, 2011)
The fatty acid composition of the moss Calliergonella cuspidata (Hedw.) Loeske (Amblystegiaccae) was preliminary analyzed by gas chromatography (GC FID) and gas chromatography-mass spectrometry (GC-MS). Six fatty acids ...
Poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)/clay composites
(Elsevier Science Sa, Lausanne, 2011)
In this study, macroporous composites of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) i.e. poly(GMA-co-EGDMA) and clay were prepared by radical suspension copolymerization. The composites with either raw ...
Chromium (VI) removal from aqueous solutions using mercaptosilane functionalized sepiolites
(Elsevier, 2011)
Natural and acid-activated sepiolite samples were functionalized with (3-Mercaptopropyl)trimethoxysilane.
By X-ray powder diffraction, Fourier transform infrared spectroscopy, and differential thermal
analysis it was ...
Geometries of stacking interactions between phenanthroline ligands in crystal structures of square-planar metal complexes
(Springer, New York, 2011)
Stacking interactions of phenanthroline square-planar complexes in crystal structures were studied by analyzing data from the Cambridge Structural Database. In most of the crystal structures, two phenanthroline complexes ...
Electrooxidation of phenol on different organo bentonite-based electrodes
(Elsevier, 2011)
Bentonite was modified by the exchange of inorganic cations with hexadecyl trimethylammonium, dodecyl trimethylammonium or tetramethylammonium cation. The obtained materials were characterized by physisorption of nitrogen ...
Ex situ bioremediation of a soil contaminated by mazut (heavy residual fuel oil) - A field experiment
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Mazut (heavy residual fuel oil)-polluted soil was exposed to bioremediation in an ex situ field-scale (600 m(3)) study. Re-inoculation was performed periodically with biomasses of microbial consortia isolated from the ...
Phenol determination on HDTMA-bentonite-based electrodes
(Elsevier, 2011)
The partial and complete substitution of cations in the interlayer region of clay with different amounts of hexadecyl trimethylammonium bromide (HDTMABr) was performed. The aim was to synthesize organo-bentonites to be ...
