Experimental results of the tribology of aluminum measured with a pin-on-disk tribometer: Testing configuration and additive effects

引用

Friction 2016年第2期4卷 124-134页

作者： S.M.H.AHMER L.S.JAN M.A.SIDDIG S.F.ABDULLAH department of physics GS Faculty Yanbu University College Yanbu al Sinayiah 41912 Kingdom of Saudi Arabia department of physics Faculty of Science and Technology al Neelain University Khartoum 11111 Sudan Mechanical Engineering department UNITEN Kajang 43009 Malaysia

The friction coefficient, wear rate, and wear coefficient of the aluminum metal surface were measured at room temperature (≈300 K) with a pin-on-disk machine at a fixed load of 196.2 N. Two different testing configurations were adopted: (1) aluminum pin vs. Helix oil-on-steel disk (AHS) and (2) aluminum pin vs. 10% Polytron plus 90% helix oil-on-steel disk (APS). In the AHS configuration, the wear of the aluminum surface was found to be approximately 70 μm; however, in the APS configuration the wear dropped to 20 μm, revealing a marked decrement of one-third of the wear of aluminum. The volume wear rate of the metal in the unaided Helix oil was estimated to be 1.28×10–3 mm3/min. The additive minimized the volume wear rate of the aluminum metal by orders of magnitude to 6.08×10–5 mm3/min. Similarly, the wear coefficient of the aluminum pin, calculated in the AHS configuration, rendered a value of 1.27×10–10 m2/N. In the APS configuration, the same parameter was 4.22×10–11 m2/N, that is to say, an order of magnitude lower than the preceding value. The observed coefficient of friction for aluminum is 0.012 in Helix oil and falls to a remarkably lower value of 0.004 through the Polytron additive. The experimental findings demonstrate that Polytron additive substantially lessens the wear of the aluminum surface; in effect, the wear coefficient and the wear rate decline linearly. This singularity may be linked to the ability of Polytron to impregnate the crystal structure of the metal due to its ionic character and the consequent adherence to the metallic surface as a hard surface layer.

Synthesis, Characterization and Photocatalytic Application of Different Sizes of Gold Nanoparticles on 4-Nitrophenol

引用

World Journal of Nano Science and Engineering 2016年第3期6卷 120-128页

作者： R. Seoudi F. A. al-Marhaby Spectroscopy department Physics Division NRC Cairo Egypt department of physics College of Applied Science Umm Al-Qura University Makkah Saudi Arabia department of physics University College in Qunfudah Umm A-Qura University Makkah Saudi Arabia

In this work, different sizes of gold nanoparticles were synthesized at room temperature by using trisodium citrate as a surfactant stabilizing agent and sodium borohydride as a reducing agent. Transmission Electron Microscopy (TEM) confirmed that the samples were synthesized in spherical shapes with three different particle sizes: 4 nm, 7 nm and 11 nm. Ultraviolet-visible spectra measurements were used to analyze the way that surface plasmon bands were affected by the different particles sizes. The effect of sphere size on photocatalytic reduction of 4-Nitrophenol was then studied and the rate constant of the reduction was calculated to be 0.014 s-1, 0.0091 s-1 and 0.003 s-1 for particles sizes of 4 nm, 7 nm and 11 nm, respectively. The results obtained indicated that small particles were more active in catalytic reduction due to their high surface energy.

Environmental and economic vision of plasma treatment of waste in Makkah

Plasma Science and Technology 2017年第10期19卷 60-69页

作者： Ahmed RIDA GalalY Guido VAN OOST department of physics Faculty of Science Beni-Suef University department of Environment and Health Research the custodian of the two holy mosques institute for Hajjand Umrah research Umm Al-Qura University department of Applied physics Ghent University National Research Nuclear university ‘MEPHI'

An environmental and economic assessment of the development of a plasma-chemical reactor equipped with plasma torches for the environmentally friendly treatment of waste streams by plasma is outlined with a view to the chemical and energetic valorization of the sustainability in the kingdom of saudi arabia（KSA）. This is especially applicable in the pilgrimage season in the city of Makkah, which is a major challenge since the amount of waste was estimated at about 750 thousand tons through Arabic Year 1435 H（2015）, and is growing at a rate of 3%–5% annually. According to statistics, the value of waste in saudi arabia ranges between 8 and 9 billion EUR. The Plasma-Treatment Project（PTP） encompasses the direct plasma treatment of all types of waste（from source and landfill）, as well as an environmental vision and economic evaluation of the use of the gas produced for fuel and electricity production in KSA, especially in the pilgrimage season in the holy city Makkah. The electrical power required for the plasmatreatment process is estimated at 5000 kW（2000 kW used for the operation of the system and 3000 kW sold）, taking into account the fact that：（1） the processing capacity of solid waste is 100 tons per day（2） and the sale of electricity amounts to 23.8 MW at 0.18 EUR per kWh.（3） The profit from the sale of electricity per year is estimated at 3.27 million EUR and the estimated profit of solid-waste treatment amounts to 6 million EUR per year and（4） the gross profit per ton of solid waste totals 8 million EUR per year. The present article introduces the first stage of the PTP, in Makkah in the pilgrimage season, which consists of five stages：（1） study and treatment of waste streams,（2） slaughterhouse waste treatment,（3） treatment of refuse-derived fuel,（4）treatment of car tires and（5） treatment of slag（the fifth stage associated with each stage from the four previous stages）.

An Econometric Time Series GDP Model Analysis: Statistical Evidences and Investigations

引用

Journal of Applied Mathematics and physics 2018年第12期6卷 2635-2649页

作者： Habib Ahmed Elsayir department of Mathematics Al Qunfudha University College Umm Al Qura University Al Qunfudha Saudi Arabia

This article aims to provide an analysis for a time series data of gross domestic product (GDP) of the Sudan. An econometric time series model with macroeconomic variables is conducted. Since a non-stationary time series must be made stationary, some statistical tests are followed so that the time series become stationary series. After applying these tests, the time series became stationary and integrated of order I. Box-Jenkins procedure is used to determine ARMA. OLS is used to estimate the models parameters. Performances chosen ARIMA model are verified on the basis of classical statistical tests and forecasting. The model features are interpreted on the basis of standard measures of forecasting performance.
