Distinguishing between natural and anthropogenic sources of trace elements in the sediments using the methods of geochemical normalization and statistical analysis
(Nova Science Publishers, Inc., 2012)
The contamination of sediments by potentially harmful trace elements is of major concern, because of their toxicity, persistence and bioaccumulative nature. In many industrial and urban areas, sediments are the largest ...
Photocatalytic properties of TiO2/WO3 coatings formed by plasma electrolytic oxidation of titanium in 12-tungstosilicic acid
(Elsevier, 2012)
In this paper, we have investigated photocatalytic properties of TiO2/WO3 coatings formed by plasma electrolytic oxidation (PEO) of titanium in 12-tungstosilicic acid water solution and compared with photocatalytic activity ...
Effects of tensile stress on electrical parameters of thin film conductive wires fabricated on a flexible substrate using stencil lithography
(Elsevier, 2012)
We report for the first time the results of tensile stress testing of thin film conductive structures patterned by stencil lithography on a PI substrate. The goal of this investigation is to determine the effects that ...
pi-Annulation reactions of 4-thiazolidinone enaminones in the synthesis of fused bi- and tri-cyclic compounds
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The a-C position in 4-oxo thiazolidinones functions as one of the three possible nucleophilic sites in these molecules. We used the inherent reactivity of alpha-C of the exocyclic double bond (a so called push pull system) ...
Carbenic vs. ionic mechanistic pathway in reaction of cyclohexanone with bromoform
(Springer, New York, 2012)
The extensive computation study was done to elucidate the mechanism of formation dibromoepoxide from cyclohexanone and bromoform. In this reaction, the formation of dihaloepoxide 2 is postulated as a key step that determines ...
High Activity and Stability of Pt2Bi Catalyst in Formic Acid Oxidation
(Springer, New York, 2012)
Formic acid oxidation was studied on a new prepared Pt2Bi characterized by X-ray diffraction spectroscopy (phase composition), scanning tunneling microscopy (STM) (surface morphology), and COads stripping voltammetry ...
An Approach to Nanobioparticles - Synthesis and Characterization of Fulleropeptides
(Wiley-V C H Verlag Gmbh, Weinheim, 2012)
Two sets of new peptides incorporating fulleropyrrolidine units Fp-GABAn-Glym-OtBu have been designed, synthesized and completely characterized. In the first series the chain contained only GABA (?-aminobutyric) residues, ...
Synergistic effect between non-ionic surfactant and halide ions in the forms of inorganic or organic salts for the corrosion inhibition of stainless-steel X4Cr13 in sulphuric acid
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The inhibition behaviour of the TRITON-X-405 mixed with KBr or C4H12NI in 2.0 M H2SO4 on the ferritic SS was studied using potentiodynamic and EIS measurements. The electrochemical data showed that mixtures used in this ...
Characterization and behavior of anesthetic bioactive textile complex in vitro condition
(Wiley-Blackwell, Malden, 2012)
In this study, a bioactive complex containing nonwoven textile material (polypropilene (PP)/viscose), chitosan hydrogel, and lidocaine hydrochloride, was designed. The purpose of such biomedical textile was in the treatment ...
Bioconjugate of Lysozyme and the Antibacterial Marine Sesquiterpene Quinone Avarone and Its Derivatives
(American Chemical Society (ACS), 2012)
A conjugate of lysozyme with avarone, a bioactive sesquiterpene quinone of marine origin, and its three derivatives were synthesized. MALDI TOF mass spectral analysis and tryptic digestion showed that the only residue in ...
