A Diffusive Gradient-in-Thin-Film Technique for Evaluation of the Bioavailability of Cd in Soil Contaminated with Cd and Pb
Management of heavy metal contamination requires accurate information about the distribution of bioavailable fractions, and about exchange between the solid and solution phases. In this study, we employed diffusive gradients in thin-films (DGT) and traditional chemical extraction methods (soil solution, HOAc, EDTA, CaCl₂, and NaOAc) to determine the Cd bioavailability in Cd-contaminated soil wi...

15 صفحه اولElectrodeposition of Thin Film Cu-Zn Shape Memory Alloys
Cu-Zn alloys have been electrodeposited from a pyrophosphate electrolyte containing Cu2P207> Zn2P207 salts and an excess of K4P2O7 and KN03. Current-potential data for both copper and zinc, as well their plating current efficiencies were determined from electrochemical polarisation experiments. Copper deposition commenced at potentials below -0.208 V whereas zinc was deposited only below -1.157...
متن کاملKinetics of thin-film reactions of Cu/a-Ge bilayers
The kinetics of the Cu3Ge phase formation during reactions between 600 nm polycrystalline Cu ~poly-Cu! and 600 nm amorphous Ge ~a-Ge! layers on Si ~100! substrates have been studied as a function of annealing conditions. Monoclinic Cu3Ge nucleated rapidly, resulting in smooth Cu3Ge layers. The room-temperature resistivity of the Cu3Ge was ;8 mV cm ~;4.5 times that of pure Cu!. The real-time res...
متن کاملPhotoinduced superhydrophilicity of TiO2 thin film with hierarchical Cu doping.
Hydrophilic Cu-TiO2 thin films with a gradient in the Cu concentration were prepared on glass by layer-by-layer dip-coating from TiO2 precursors. The effects of the Cu doping on the structure and properties of TiO2 self-cleaning thin films are discussed. The Cu gradient markedly affects the hydrophilicity of the films, with the water contact angle significantly reduced compared with those of th...
