Morphology and structure of bright electrodeposited metal coatings
(Soc Chemists Technologists Madeconia, Skopje, 2011)
The properties which determine whether the metal surface is mirror bright are precisely determined by scanning electron microscopy (SEM), atomic forces microscopy (AFM), scanning tunneling microscopy (STM) and reflectance ...
Reactions of transition metal carbonyl anions with 2-(1-bromoalkylidene)thiazolidin-4-ones: halogenophilic attack or deprotonation
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Bromophilic attack by the transition metal carbonyl anion, [Re(CO)(5)]Na (pK(a) = 21.1), on 2-(1-bromoalkylidene)thiazolidin-4-ones is significantly faster than abstraction of an acidic lactam hydrogen (pK(a) similar to ...
Computational analysis of tris(1,2-ethanediamine) cobalt(III) complex ion: calculation of the Co-59 shielding tensor using LF-DFT
(Springer Wien, Wien, 2011)
The ligand-field density functional theory (LF-DFT) approach is employed for calculations of the Co-59 nuclear magnetic resonance (NMR) shielding tensor of all four diastereoisomers (lambda lambda lambda, lambda lambda I ...
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 ...
Negative Refractive Index Metasurfaces for Enhanced Biosensing
(MDPI, 2011)
In this paper we review some metasurfaces with negative values of effective refractive index, as scaffolds for a new generation of surface plasmon polariton-based biological or chemical sensors. The electromagnetic properties ...
The comparison of sample extraction procedures for the determination of cations in soil by IC and ICP-AES
(Versita, Warsaw, 2011)
This paper presents the extraction of cations from a soil sample, type ranker on serpentinite, in deionized water, by use of three different extraction techniques. The first extraction technique included the use of a rotary ...
Electrochemical synthesis and corrosion behavior of polyaniline-benzoate coating on copper
(Elsevier Science Sa, Lausanne, 2011)
Electrochemical polymerization of polyaniline (PANI) coating on copper electrode was performed galvanostatically in the current density range between 0.50 and 1.25 mA cm(-2), from aqueous solution of 0.3 mol dm(-3) sodium ...
Correlation between structure, retention and activity of cholic acid derived cis-trans isomeric bis-steroidal tetraoxanes
(Wiley-V C H Verlag Gmbh, Weinheim, 2011)
Both quantitative structure-retention (QSRR) and quantitative structure-activity relationship (QSAR) studies have been performed to correlate the molecular characteristics of seven pairs of cis-trans isomeric bis-steroidal ...
Structural diversification of the coordination mode of divalent metals with 1,3-propanediaminetetraacetate (1,3-pdta): The missing crystal structure of the s-block metal complex [Sr-2(1,3-pdta)(H2O)(6)]center dot H2O
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
This paper reports the synthesis and X-ray characteristics of the missing homonuclear s-block metal complex {[Sr-2(1,3-pdta)(H2O)(6)]center dot H2O}(n). In the title compound, the hexadentate 1,3-propanediaminetetraacetate ...
