Nitrate (NO3) contamination of groundwater is a major concern throughout intensive agricultural areas. In the present laboratory scale study, an electrolytic reduction method employing copper cathode and insoluble triple mixed oxide anode was studied for the denitrification of groundwater in a divided cell. Influence of process parameters such as pH, current density and time were studied and th...

Recently a fingering morphology, resembling the hydrodynamic Saffman-Taylor instability, was identified in the quasi-two-dimensional electrodeposition of copper. We present here measurements of the dispersion relation of the growing front. The instability is accompanied by gravity-driven convection rolls at the electrodes, which are examined using particle image velocimetry. While at the anode ...

This paper reports a simple isoelectric focusing (IEF) technique without carrier ampholytes to generate stable pH gradients in a nitrocellulose membrane for the fabrication of paper-based analytical devices suitable for complex biological samples. To design the custom-built IEF apparatus, silver-coated copper wire electrodes were employed; the distance between anode and cathode was 8 mm. Concen...

Ultraviolet-ozone-treated poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)was used as the anode buffer layer in copper phthalocyanine (CuPc)/fullerene-based solar cells. The power conversion efficiency of the cells with appropriated UV-ozone treatment was found to increase about 20% compared to the reference cell. The improved performance is attributed to the increased work ...

icle as: M.T. McDow hiation/delithiatio Abstract Applying surface coatings to alloying anodes for Li-ion batteries can improve rate capability and cycle life, but it is unclear how this second phase affects mechanical deformation during electrochemical reaction. Here, in-situ transmission electron microscopy is employed to investigate the electrochemical lithiation and delithiation of silicon n...

Crude copper with a high content of impurities derived from secondary raw materials, known as black-copper, cannot be used in the conventional electrorefining process because passivation. The current industrial for which involves combination high-temperature acid dissolution under pressure, and subsequent electrowinning, results power consumption. In this study, basket electrolysis method was i...
