Utilization of the Phaseolus vulgaris L. waste biomass for decolorization of the textile dye Acid Red 57: determination of equilibrium, kinetic and thermodynamic parameters
(Taylor & Francis Inc, 2007)
In the present study, biosorption of Acid Red 57 (AR57) onto a waste biomass of Phaseolus vulgaris L. was investigated by varying pH, contact time, biosorbent concentration and temperature, to determine the equilibrium, ...
Cr(III)-imprinted polymeric beads: Sorption and preconcentration studies
(Elsevier Science BV, 2007)
The purpose of this study is to prepare a novel molecular imprinted adsorbent to Cr(III) analysis with high selectivity. Initially, chromium (III)-methacryloylhistidine (MAH/Cr(III)) complex monomer was synthesized and ...
Exact solutions in five-dimensional axi-dilaton gravity with Euler-Poincare term
(IOP Publishing LTD, 2007)
We examine the effective field equations that are obtained from the axi-dilaton gravity action with a second-order Euler-Poincare term and a cosmological constant in all higher dimensions. We solve these equations for ...
The effects of fluorine on the structural, surface morphology and optical properties of ZnO thin films
(Elsevier Science BV, 2007)
The optical and structural properties of fluorine-doped Zinc oxide (ZnO) thin films have been investigated. The X-ray diffraction spectra indicate that the films have polycrystalline nature. A ZnO single phase with a ...
Effects of In, Al and Sn dopants on the structural and optical properties of ZnO thin films
(Pergamon-Elsevier Science LTD, 2007)
Effect of In, Al and Sn dopants on the optical and structural properties of ZnO thin films have been investigated by X-ray diffraction technique and optical characterization method. X-ray diffraction patterns confirm that ...
Determination of the thickness and optical constants of transparent indium-doped ZnO thin films by the envelope method
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2007)
Transparent indium-doped ZnO thin films were deposited by the spray pyrolysis method onto glass substrates. The content of indium in the starting solution was 0.5 at. %. The crystallographic structure of the film was studied ...
Single-oscillator model and determination of optical constants of spray pyrolyzed amorphous SnO2 thin films
(Springer, 2007)
Amorphous SnO2 thin films have been deposited using different spraying times via the spray pyrolysis method. The structure of the films was analyzed by X-ray diffraction and the results obtained showed that the structure ...
Ion-imprinted beads for molecular recognition based mercury removal from human serum
(Elsevier Science BV, 2007)
The aim of this study is to prepare ion-imprinted polymers which can be used for the selective removal of mercury ions [Hg2+] from human serum. N-Methacryloyl-(L)-cysteine (MAC) was chosen as the complexing monomer. In the ...
FT-IR spectroscopic study of the Hofmann-Td-type clathrates: Ni(1,9-diaminononane)M'(CN)4·2G (M' = Cd or Hg, G = benzene, 1,2-dichlorobenzene or 1,4-dichlorobenzene)
(2007)
New Hofmann Td-type clathrates in the form of Ni(1,9-diaminononane)M'(CN)4·2G (M' = Cd or Hg, G = benzene, 1,2-dichlorobenzene or 1,4-dichlorobenzene) were prepared in powder form and their infrared spectra are reported ...
Influence of the thickness on physical properties of chemical bath deposited hexagonal ZnS thin films
(2007)
Hexagonal ZnS thin films of thicknesses ranging between 454 to 750 nm are deposited on a glass substrate by chemical bath deposition at 80 °C. The ZnS thin films are characterized by X-ray diffraction (XRD) and optical ...
