In this research, the treatability of slaughterhouse wastewater was investigated by using electrochemical method with Mg electrodes. The influence variables such as initial pH (4, 5, 6, 7, 8, and 9), current density (15, 30, 45 mA/cm2), reaction time (20, 25, 30 min) on removal efficiency ammonium phosphate studied. highest reached at 100% after 20 min treatment mA/cm2 6. Meanwhile, maximum per...

This work demonstrates the dynamic through-silicon-via (TSV) filling process through staged electrodeposition experiments at different current densities. Different morphologies corresponding to TSV filling results can be obtained by controlling the applied current density. Specifically, a low current density (4 mA/cm2) induces seam defect filling, a medium current density (7 mA/cm2) induces def...

This paper examines basic crossed-field device physics in a planar configuration, specifically electron beam perturbation and instability as function of variation magnetic field, angle between electric field. We perform three-dimensional (3-D) simulation system using the full 3-D particle trajectory solver CST Particle Studio (CST-PS). The structure has length, height, width anode-sole gap 15 c...

The use of organic waste as fuel for energy generation will reduce the great environmental problems currently caused by consumption fossil sources, giving agribusiness companies a profitable way to their waste. In this research, tomato with different percentages sucrose (0-target, 5, 10, and 20%) was used in microbial cells manufactured on laboratory scale zinc copper electrodes, managing gener...

In the present study, PtRuCe/MWNTs nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (MOR). To characterize the nanocatalysts, TEM, XRD, EDS and XPS are investigated. Cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activ...

A new approach based on pulse electrodeposition is demonstrated to be an attractive technique to replace conventional powder type membrane electrode assembly (MEA) preparation methods. The performance of the catalyst layer is optimized by controlling the pulse deposition parameters such as the peak current density, duty cycle and the total charge density. The peak current density and the pulse ...

The aim of this research was to evaluate the effective parameters such as pH, current density (mA/cm2), H2O2/Fe2+ molar ratio, volume ratio of H2O2 to pharmaceutical wastewater (PhW) (ml/l) and reaction time (min) on the electro-Fenton process for the ibuprofen (as a pharmaceutical waste in water) removal. Since a synthetic wastewater with the same concentration of ibuprofen in a real pharmaceu...

The optics of axial silicon nanowire solar cells is investigated and compared to silicon thin-film solar cells with textured contact layers. The quantum efficiency and short circuit current density are calculated taking a device geometry into account, which can be fabricated by using standard semiconductor processing. The solar cells with textured absorber and textured contact layers provide a ...
