terms and conditions of current drinking water quality standards, including reducing the maximum arsenic concentration from 50 μgl-1 to 10 μgl-1 and predicted stricter standards in future, reveals the necessity for development of new technologies. this study aimed to prepare and evaluate a new nanocomposite membrane using graphene oxide (go) thin layer to remove arsenic (v) from water. to fabri...

In the current work, graphene oxide (GO) samples were prepared at room temperature from graphite flakes using a modified Hummer's method to produce metal-free electrocatalysts. The effect of the duration of the oxidation process on the structural, chemical and physical characteristics of the GO samples was evaluated using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ...

Improvements in durable lubrication together with minimized wear are essential for obtaining long-term, functioning metallic joint prostheses. To achieve this objective, CoCr surface was functionalized Graphene Oxide (GO) and characterized by FTIR XPS. alloy subjected to alkalinization order generate high hydroxyl content on the surface. XPS revealed reactive OH groups, enabling intermediate co...

D promising reforms following the civil rights movement of the 1960s and continuing through the 1970s, the progress of black men since the early 1980s has been relatively stagnant. The black-white gaps in high school graduation, earnings, and unemployment have improved little over the past 30 years. On some indicators, black men are doing steadily worse: faced with poor employment prospects, le...
