The electrochemical processes that occur at aluminium electrodes give excellent performance. In this work, electrocoagulation tests were carried out on an industrial effluent from an electroplating bath located in Casablanca (Morocco). The aim was to remove chromium and reuse the purified water for other purposes within the company. To this end, we have optimised the operating parameters that affect the efficiency of electrocoagulation, such as electrical voltage, electrode material, stirring speed and distance between electrodes. We also evaluated these parameters. The effect on pH, conductivity, turbidity and chromium concentration. The tests were carried out in a perfectly stirred reactor on an industrial solution rich in chromium. The effluent concentration was 1000 mg/L of Cr6+. Chromium removal efficiency was determined for the following operating conditions: aluminium electrodes, regulated voltage of 6 volts and 12 volts, optimum stirring speed of 600 rpm and distance between electrodes of 2 cm. The sludge produced by electrocoagulation was characterised by X-ray diffractometry, infrared spectroscopy (IR) and scanning electron microscopy (SEM). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wastewater" title="wastewater">wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium" title=" chromium"> chromium</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation" title=" electrocoagulation"> electrocoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminium" title=" aluminium"> aluminium</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminium%20hydroxide" title=" aluminium hydroxide"> aluminium hydroxide</a> </p> <a href="https://publications.waset.org/abstracts/171096/study-of-electrocoagulation-on-the-elimination-of-chromium-in-waste-water-from-an-electroplating-bath-using-aluminium-electrodes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171096.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">707</span> Simulation of the Extensional Flow Mixing of Molten Aluminium and Fly Ash Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Ualibek">O.

The geopolymers were prepared using aluminium dross from secondary aluminium industry, fly ash from a biomass power plant and liquid alkaline activators, which is a mixture of sodium silicate solution (Na2SiO3) and sodium hydroxide solution (NaOH) (Na2SiO3/NaOH ratio 4:1, 3:1 and 2:1). Aluminium dross consists mostly of alumina (Al2O3), silicon oxide (SiO2) and aluminium nitride (AlN). The raw materials were mixed and milled using the high energy ball milling method for 5, 10 and 15 minutes in order to reduce the particle size. The milled powders were uniaxially pressed into a cylinder die with the pressure of 2200 psi. The cylinder samples were cured in the sealed plastic bags for 3, 7 and 14 days at the room temperature and 60°C for 24 hour. The mechanical property of geopolymers was investigated. In addition, scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis were carried out in order to study the microstructure and phase structures of the geopolymers, respectively. The results showed that aluminium dross could enhance the mechanical property of geopolymers product by mechanochemistry method and meet the TISI requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium%20dross" title="aluminium dross">aluminium dross</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title=" fly ash"> fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=geopolymer" title=" geopolymer"> geopolymer</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanochemistry" title=" mechanochemistry"> mechanochemistry</a> </p> <a href="https://publications.waset.org/abstracts/60359/utilization-of-aluminium-dross-as-a-main-raw-material-for-synthesize-the-geopolymers-via-mechanochemistry-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60359.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">253</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">705</span> Influence of Post Weld Heat Treatment on Mechanical and Metallurgical Properties of TIG Welded Aluminium Alloy Joints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurmeet%20Singh%20Cheema">Gurmeet Singh Cheema</a>, <a href="https://publications.waset.org/abstracts/search?q=Navjotinder%20Singh"> Navjotinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh"> Gurjinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amardeep%20Singh"> Amardeep Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aluminium and its alloys play have excellent corrosion resistant properties, ease of fabrication and high specific strength to weight ratio.

For instance, the DO oxidises Fe (II) to Fe (III), As (III) to As (V), and cyanide to cyanate and then to ammonia. As well as, removal of nitrogenous compounds accomplishes by the presence of DO. Hence, many of the previous investigations used external aerators to provide the required DO inside EC reactors especially when the water being treated has low DO (such as leachate and highly polluted waters with organic matter); or when the DO depleted during the EC treatment. Although the external aeration process effectively enhances the DO concentration, it has a significant impact on energy consumption. Where, the presence of air bubbles increases the electrical resistance of the EC cell that increase the energy consumption in consequence. Thus, the present project aims to fill this gap by an innovative use of perforated flow columns in the designing of a new EC reactor (ECR1). The new reactor (ECR1) consisted of a Perspex made cylinder container having a controllable working volume of 0.5 to 1 L. It supplied with a flow column that consisted of perorated discoid electrodes that made from aluminium. In order to investigate the performance of ECR1; water samples with a controlled DO concentration were pumped at different flow rates (110, 220, and 440 ml/min) to the ECR1 for 10 min. The obtained results demonstrated that the ECR1 increased the DO concentration from 5.0 to 9.54, 10.53, and 11.0 mg/L which equivalent to 90.8%, 110.6%, and 120% at flow rates of 110, 220, and 440 mL/min respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dissolved%20oxygen" title="dissolved oxygen">dissolved oxygen</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20column" title=" flow column"> flow column</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation" title=" electrocoagulation"> electrocoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminium%20electrodes" title=" aluminium electrodes"> aluminium electrodes</a> </p> <a href="https://publications.waset.org/abstracts/40025/enhancement-of-dissolved-oxygen-concentration-during-the-electrocoagulation-process-using-an-innovative-flow-columns-electrocoagulation-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40025.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">273</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">703</span> An Evaluation of the Oxide Layers in Machining Swarfs to Improve Recycling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Uka">J.

Aluminium swarf briquettes underwent treatments at different temperatures and cooling times to investigate the improvements obtained in the recovery of aluminium metal. The main issue for the recovery of the metal from swarfs is to overcome the constraints due to the oxide layers present in high concentration in the swarfs since they have a high surface area. Briquettes supplied by Renishaw were heat treated at 650, 700, 750, 800 and 850 ℃ for 1-hour and then cooled at 2.3, 3.5 and 5 ℃/min. The resulting material was analysed using SEM EDX to observe the oxygen diffusion and aluminium coalescence at the boundary between adjacent swarfs. Preliminary results show that, swarf needs to be heat treated at a temperature of 850 ℃ and cooled down slowly at 2.3 ℃/min to have thin and discontinuous alumina layers between the adjacent swarf and consequently allowing aluminium coalescence. This has the potential to save energy and provide maximum financial profit in preparation of swarf briquettes for recycling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reuse" title="reuse">reuse</a>, <a href="https://publications.waset.org/abstracts/search?q=recycle" title=" recycle"> recycle</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminium" title=" aluminium"> aluminium</a>, <a href="https://publications.waset.org/abstracts/search?q=swarf" title=" swarf"> swarf</a>, <a href="https://publications.waset.org/abstracts/search?q=oxide%20layers" title=" oxide layers"> oxide layers</a> </p> <a href="https://publications.waset.org/abstracts/130238/an-evaluation-of-the-oxide-layers-in-machining-swarfs-to-improve-recycling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130238.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">133</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">702</span> Wire Arc Additive Manufacturing of Aluminium–Magnesium Alloy AlMg4.5Mn With TiC Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javad%20Karimi">Javad Karimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The grain morphology and size of the additively manufactured (AM) aluminium alloys play a vital role in the performance and mechanical properties.

The supporting macroporous Ni electrodes have been obtained by means of the electrodeposition at high current densities. Then, the Au nanoparticles were synthesized and added to the electrode surface. The electrocatalytic behaviour of the developed electrocatalysts was studied by means of pseudo-steady-state polarization curves, electrochemical impedance spectroscopy (EIS) and hydrogen discharge curves. The size of the Au synthetized nanoparticles shows a monomodal distribution, with a very sharp band between 10 and 50 nm. The characteristic parameters d10, d50 and d90 were 14, 20 and 31 nm respectively. From Tafel polarization data has been concluded that the Au nanoparticles improve the catalytic activity of the developed electrodes towards the HER respect to the macroporous Ni electrodes. EIS permits to obtain the electrochemically active area by means of the roughness factor value. All the developed electrodes show roughness factor values in the same order of magnitude. From the activation energy results it can be concluded that the Au nanoparticles improve the intrinsic catalytic activity of the macroporous Ni electrodes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Au%20nano%20particles" title="Au nano particles">Au nano particles</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20evolution%20reaction" title=" hydrogen evolution reaction"> hydrogen evolution reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20Ni%20electrodes" title=" porous Ni electrodes"> porous Ni electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20impedance%20spectroscopy" title=" electrochemical impedance spectroscopy "> electrochemical impedance spectroscopy </a> </p> <a href="https://publications.waset.org/abstracts/27355/porous-ni-electrodes-modified-with-au-nanoparticles-for-hydrogen-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27355.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">622</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">700</span> A Metallography Study of Secondary A226 Aluminium Alloy Used in Automotive Industries </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Hurtalov%C3%A1">Lenka Hurtalová</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Tillov%C3%A1"> Eva Tillová</a>, <a href="https://publications.waset.org/abstracts/search?q=M%C3%A1ria%20Chalupov%C3%A1"> Mária Chalupová</a>, <a href="https://publications.waset.org/abstracts/search?q=Juraj%20Belan"> Juraj Belan</a>, <a href="https://publications.waset.org/abstracts/search?q=Milan%20Uhr%C3%AD%C4%8Dik"> Milan Uhríčik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The secondary alloy A226 is used for many automotive casting produced by mould casting and high pressure die-casting. This alloy has excellent castability, good mechanical properties and cost-effectiveness. Production of primary aluminium alloys belong to heavy source fouling of life environs. The European Union calls for the emission reduction and reduction in energy consumption, therefore, increase production of recycled (secondary) aluminium cast alloys. The contribution is deal with influence of recycling on the quality of the casting made from A226 in automotive industry. The properties of the casting made from secondary aluminium alloys were compared with the required properties of primary aluminium alloys. The effect of recycling on microstructure was observed using combination different analytical techniques (light microscopy upon black-white etching, scanning electron microscopy-SEM upon deep etching and energy dispersive X-ray analysis-EDX). These techniques were used for the identification of the various structure parameters, which was used to compare secondary alloy microstructure with primary alloy microstructure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=A226%20secondary%20aluminium%20alloy" title="A226 secondary aluminium alloy">A226 secondary aluminium alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20etching" title=" deep etching"> deep etching</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling%20foundry%20aluminium%20alloy" title=" recycling foundry aluminium alloy"> recycling foundry aluminium alloy</a> </p> <a href="https://publications.waset.org/abstracts/20090/a-metallography-study-of-secondary-a226-aluminium-alloy-used-in-automotive-industries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20090.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">541</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">699</span> Effect of Electrodes Spacing on Energy Consumption of Electrocoagulation Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20S.%20Hashim">Khalid S.

Hence, optimizing these key operating parameters is considered a vital step to remove a pollutant efficiently. In this context, the present study has been carried out to explore the influence of electrodes spacing on energy consumption, temperature of the water being treated, and iron removal from water. To achieve this target, iron containing synthetic water samples were electrolysed for 20 min, using a new flow column electrocoagulation reactor (FCER), at three different gaps between electrodes (5, 10, and 20 mm). These batch experiments were commenced at a constant current density of 1.5 mA/cm² and initial pH of 6. The obtained results demonstrated that increasing gap between electrodes negatively influenced the performance of the EC method. It was found that increasing the gap between electrodes from 5 to 20 mm increased the energy consumption from about 3.3 to 7.3 kW.h/m³, and water temperature from 20.2 to 22 °C, respectively. In addition, it has been found, after 20 min of electrolysing, that increasing the gap between electrodes from 5 to 20 mm increased the residual iron concentration from 0.05 to 1.01 mg/L, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation" title="electrocoagulation">electrocoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodes" title=" electrodes"> electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=iron" title=" iron"> iron</a> </p> <a href="https://publications.waset.org/abstracts/72173/effect-of-electrodes-spacing-on-energy-consumption-of-electrocoagulation-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72173.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">698</span> Characterization of Graphene Oxide Coated Gold Electrodes for Bioimpedance Measurements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20G%C3%BClden%20%C5%9Ei%CC%87m%C5%9Fek">Fatma Gülden Şi̇mşek</a>, <a href="https://publications.waset.org/abstracts/search?q=Osman%20Meli%CC%87h%20Can"> Osman Meli̇h Can</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Yumak"> Mehmet Yumak</a>, <a href="https://publications.waset.org/abstracts/search?q=Bora%20Gari%CC%87pcan"> Bora Gari̇pcan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yekta%20%C3%9Clgen"> Yekta Ülgen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the impedance spectroscopy is used as a detection tool in order to characterize surface coating with graphene oxide.

Premodulated IFC and ‘true’ IFC at beat frequencies of 4, 40 and 90Hz were applied via four electrodes to the distal medial thigh of 15 healthy subjects. The current was measured via three Teflon coated fine needle electrodes that were inserted into the superficial layer of skin, then into the subcutaneous tissue (≈1 cm deep) and then into muscle tissue (≈2 cm deep). The needle electrodes were placed in the middle of the four IFC electrodes, between two channels and outside the four electrodes. Readings were taken at each tissue depth from each electrode during each treatment frequency then digitized and stored for analysis. All voltages were greater at all depths and locations than baseline (p < 0.01) and voltages decreased with depth (P=0.039). Lower voltages of all currents were recorded in the middle of the four electrodes with the highest voltage being recorded outside the four electrodes in all depths (P=0.000).For each frequency of ‘true’ IFC, the voltage was higher in the superficial layer outside the electrodes (P ≤ 0.01).Premodulated had higher voltages along the line of one circuit (P ≤ 0.01). Clinically, IFC appears to pass through skin layers to depth and is more efficient than premodulated IFC when targeting muscle tissue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrotherapy" title="electrotherapy">electrotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=interferential%20current" title=" interferential current"> interferential current</a>, <a href="https://publications.waset.org/abstracts/search?q=interferential%20therapy" title=" interferential therapy"> interferential therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=medium%20frequency%20current" title=" medium frequency current"> medium frequency current</a> </p> <a href="https://publications.waset.org/abstracts/20986/depth-of-penetration-and-nature-of-interferential-current-in-cutaneous-subcutaneous-and-muscle-tissues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20986.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">347</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">695</span> The Effects of Root Zone Supply of Aluminium on Vegetative Growth of 15 Groundnut Cultivars Grown in Solution Culture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mosima%20M.%20Mabitsela">Mosima M. Mabitsela</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundnut is preferably grown on light textured soils. Most of these light textured soils tend to be highly weathered and characterized by high soil acidity and low nutrient status. One major soil factor associated with infertility of acidic soils that can negatively depress groundnut yield is aluminium (Al) toxicity. In plants Al toxicity damages root cells, leading to inhibition of root growth as a result of the suppression of cell division, cell elongation and cell expansion in the apical meristem cells of the root. The end result is that roots become stunted and brittle, root hair development is poor, and the root apices become swollen. This study was conducted to determine the effects of aluminium (Al) toxicity on a range of groundnut varieties. Fifteen cultivars were tested in incremental aluminum (Al) supply in an ebb and flow solution culture laid out in a randomized complete block design. There were six aluminium (Al) treatments viz. 0 µM, 1 µM, 5.7 µM, 14.14 µM, 53.18 µM, and 200 µM. At 1 µM there was no inhibitory effect on the growth of groundnut. The inhibition of groundnut growth was noticeable from 5.7 µM to 200 µM, where the severe effect of aluminium (Al) stress was observed at 200 µM. The cultivars varied in their response to aluminium (Al) supply in solution culture. Groundnuts are one of the most important food crops in the world, and its supply is on a decline due to the light-textured soils that they thrive under as these soils are acidic and can easily solubilize aluminium (Al) to its toxic form. Consequently, there is a need to develop groundnut cultivars with high tolerance to soil acidity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium%20toxicity" title="aluminium toxicity">aluminium toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=cultivars" title=" cultivars"> cultivars</a>, <a href="https://publications.waset.org/abstracts/search?q=reduction" title=" reduction"> reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20growth" title=" root growth"> root growth</a> </p> <a href="https://publications.waset.org/abstracts/102083/the-effects-of-root-zone-supply-of-aluminium-on-vegetative-growth-of-15-groundnut-cultivars-grown-in-solution-culture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102083.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">694</span> Enhanced Performance of an All-Vanadium Redox Flow Battery Employing Graphene Modified Carbon Paper Electrodes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Barun%20Chakrabarti">Barun Chakrabarti</a>, <a href="https://publications.waset.org/abstracts/search?q=Dan%20Nir"> Dan Nir</a>, <a href="https://publications.waset.org/abstracts/search?q=Vladimir%20Yufit"> Vladimir Yufit</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20V.%20Aravind"> P.

Since the electric signal needs electrodes to be transmitted to an organism, electrodes play an important role of stimulations. The materials of stimulation electrodes affect the efficiency of the delivered currents. The higher the efficiency of the electrodes, the lower the threshold current can be used to stimulate the organism which minimizes the potential damages to the adjacent tissues. In this study, we proposed a biocompatible composite electrode composed of high-charge-capacity iridium oxide (IrOₓ) film for a bone-guide extra-cochlear implant. IrOₓ was exploited to decrease the threshold current due to its high capacitance and low impedance. The IrOₓ electrode was fabricated via microelectromechanical systems (MEMS) photolithography and examined with in-vivo tests with guinea pigs. Based on the measured responses of brain waves to sound, the results demonstrated that IrOₓ electrodes have a lower threshold current compared with the Platinum (Pt) electrodes. The research results are expected to be beneficial for implantable and biocompatible electrodes for electrical stimulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cochlear%20implants" title="cochlear implants">cochlear implants</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode" title=" electrode"> electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20stimulation" title=" electrical stimulation"> electrical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=iridium%20oxide" title=" iridium oxide"> iridium oxide</a> </p> <a href="https://publications.waset.org/abstracts/100114/developing-biocompatible-iridium-oxide-electrodes-for-bone-guided-extra-cochlear-implant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100114.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">189</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">691</span> Corrosion Characterization of Al6061, Quartz Metal Matrix Composites in Alkali Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radha%20H.%20R.">Radha H.

In this work the matrix selected is Aluminium 6061 alloy which is commercially available and the reinforcement selected is quartz particulates of 50-80 micron size which is available in plenty in and around Bangalore district, India. Composites containing Aluminium 6061 with 2, 4 and 6 weight percent of quartz are manufactured by liquid melt metallurgy technique using vortex method. Corrosion tests like static weight loss and open circuit potential tests are conducted in different concentrated solutions of sodium hydroxide. To compare the results the matrix Aluminium 6061 is also casted in the same way. Specimens for the test are prepared according to ASTM standards. In all the tests the metal matrix composites showed better corrosion resistance than matrix alloy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium%206061" title="aluminium 6061">aluminium 6061</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=quartz" title=" quartz"> quartz</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex" title=" vortex "> vortex </a> </p> <a href="https://publications.waset.org/abstracts/24586/corrosion-characterization-of-al6061-quartz-metal-matrix-composites-in-alkali-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24586.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">409</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">690</span> Influence of Dry-Film Lubricants on Bond Strength and Corrosion Behaviour of 6xxx Aluminium Alloy Adhesive Joints for Automotive Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ralph%20Gruber">Ralph Gruber</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Hafner"> Martina Hafner</a>, <a href="https://publications.waset.org/abstracts/search?q=Theresia%20Greunz"> Theresia Greunz</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Reisecker"> Christian Reisecker</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Stifter"> David Stifter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The application of dry lubricant on aluminium for automotive industry is indispensable for a high-quality forming behaviour. To provide a short production time those forming aids will not be removed during the joining step. The aim of this study was the characterization of the influence of dry lubricants on the bond strength and the corrosion resistance of an 6xxx aluminium alloy for automotive applications. For this purpose, samples with a well-defined surface were lubricated with 1 g/m² dry lubricant and joined with a commercial thermosetting 1K-epoxy structural adhesive. The bond strength was characterized by means of lap shear test. To evaluate the corrosion resistance of the adhered aluminium samples an immersion test in 5 w% NaCl-solution was used. Based on fracture pattern analysis, the corrosion behaviour could be described. Dissolved corrosion products were examined using ICP-MS and NMR. By means of SEM/EDX the elementary composition of precipitated solids was determined. The results showed a dry lubricant independent bond strength for standard testing conditions. However, a significant effect of the forming aid, regarding the corrosion resistance of adhered aluminium samples against corrosive infiltration of the metal-adhesive-interface, was observed <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium%20alloys" title="aluminium alloys">aluminium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20film%20lubricants" title=" dry film lubricants"> dry film lubricants</a>, <a href="https://publications.waset.org/abstracts/search?q=automotive%20industry" title=" automotive industry"> automotive industry</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesive%20bonding" title=" adhesive bonding"> adhesive bonding</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a> </p> <a href="https://publications.waset.org/abstracts/154769/influence-of-dry-film-lubricants-on-bond-strength-and-corrosion-behaviour-of-6xxx-aluminium-alloy-adhesive-joints-for-automotive-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154769.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">689</span> Effects of Array Electrode Placement on Identifying Localised Muscle Fatigue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20R.%20Al-Mulla">Mohamed R.

In the beginning, single electrodes were utilised; however, the newest approach is to use an array of electrodes or a grid of electrodes to improve the accuracy of the recorded reading. This research focuses on electrode placement on the biceps brachii, using an array of electrodes placed longitudinal and diagonally on the muscle belly. Trials were conducted on four healthy males, with sEMG signal acquisition from fatiguing isometric contractions. The signal was analysed using the power spectrum density. The separation between the two classes of fatigue (non-fatigue and fatigue) was calculated using the Davies-Bouldin Index (DBI). Results show that higher separability between the fatigue content of the sEMG signal when placed longitudinally, in the same direction as the muscle fibers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=array%20electrodes" title="array electrodes">array electrodes</a>, <a href="https://publications.waset.org/abstracts/search?q=biceps%20brachii" title=" biceps brachii"> biceps brachii</a>, <a href="https://publications.waset.org/abstracts/search?q=electrode%20placement" title=" electrode placement"> electrode placement</a>, <a href="https://publications.waset.org/abstracts/search?q=EMG" title=" EMG"> EMG</a>, <a href="https://publications.waset.org/abstracts/search?q=isometric%20contractions" title=" isometric contractions"> isometric contractions</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20fatigue" title=" muscle fatigue"> muscle fatigue</a> </p> <a href="https://publications.waset.org/abstracts/63793/effects-of-array-electrode-placement-on-identifying-localised-muscle-fatigue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63793.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">688</span> A Life Cycle Assessment (LCA) of Aluminum Production Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaa%20Al%20Hawari">Alaa Al Hawari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Khader"> Mohammad Khader</a>, <a href="https://publications.waset.org/abstracts/search?q=Wael%20El%20Hasan"> Wael El Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Alijla"> Mahmoud Alijla</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Manawi"> Ammar Manawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelbaki%20Benamour"> Abdelbaki Benamour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The production of aluminium alloys and ingots -starting from the processing of alumina to aluminium, and the final cast product- was studied using a Life Cycle Assessment (LCA) approach. The studied aluminium supply chain consisted of a carbon plant, a reduction plant, a casting plant, and a power plant. In the LCA model, the environmental loads of the different plants for the production of 1 ton of aluminium metal were investigated. The impact of the aluminium production was assessed in eight impact categories. The results showed that for all of the impact categories the power plant had the highest impact only in the cases of Human Toxicity Potential (HTP) the reduction plant had the highest impact and in the Marine Aquatic Eco-Toxicity Potential (MAETP) the carbon plant had the highest impact. Furthermore, the impact of the carbon plant and the reduction plant combined was almost the same as the impact of the power plant in the case of the Acidification Potential (AP). The carbon plant had a positive impact on the environment when it comes to the Eutrophication Potential (EP) due to the production of clean water in the process. The natural gas based power plant used in the case study had 8.4 times less negative impact on the environment when compared to the heavy fuel based power plant and 10.7 times less negative impact when compared to the hard coal based power plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title="life cycle assessment">life cycle assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminium%20production" title=" aluminium production"> aluminium production</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20impacts" title=" ecological impacts"> ecological impacts</a> </p> <a href="https://publications.waset.org/abstracts/8005/a-life-cycle-assessment-lca-of-aluminum-production-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8005.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">532</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">687</span> Biologically Synthesized Palladium Nanoparticles Impregnated Porous Aluminium Catalyst in CO2 Detection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20B.%20Patel">I.

Doped aluminium oxides (DAO) using silvery white coloured alkaline earth metals such as Mg and Ca as dopants in the concentration of 0.4 % are synthesized by microwave combustion method and referred as MA ( Mg doped aluminium oxide) and CA ( Ca doped aluminium oxide). The as-synthesized materials are characterized for the electrical resistance, X–ray diffraction, FE-SEM, TEM and FTIR. The electrical resistances of the DAOs are observed to be ~ 8-20 MΩ. This means that the resistance of aluminium oxide (Corundum) α-Al2O3 which is ~ 1010Ω is reduced by the order of ~ 103 to 104 Ω after doping. XRD studies reveal the doping of Mg and Ca in aluminium oxide. The microstructural study using FE-SEM shows the flaky clusterous structures with the thickness of the flakes between 10 and 20 nm. TEM images depict the rod-shaped morphological geometry of the particles with the diameter of ~50-70 nm. The nanocomposites are synthesized by incorporating the DAOs in the concentration of 75 phr (parts per hundred parts of rubber) into VMQ polymer. The electrical resistance of VMQ polymer, which is ~ 1015Ω, drops by the order of 108Ω. There is a retention of the electrical resistance of ~ 30-50 MΩ for the nanocomposites which is a static dissipative range of electricity. In this work white coloured electrically conductive VMQ polymer-DAO nanocomposites (MAVMQ for Mg doping and CAVMQ for Ca doping) have been synthesized. The physical and mechanical properties of the composites such as specific gravity, hardness, tensile strength and rebound resilience are measured. Hardness and tensile strength are found to increase, with the negligible alteration in the other properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doped%20aluminium%20oxide" title="doped aluminium oxide">doped aluminium oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=methyl%20vinyl%20silicone%20polymer" title=" methyl vinyl silicone polymer"> methyl vinyl silicone polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20synthesis" title=" microwave synthesis"> microwave synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20dissipation" title=" static dissipation"> static dissipation</a> </p> <a href="https://publications.waset.org/abstracts/33200/preparation-static-dissipative-nanocomposites-of-alkaline-earth-metal-doped-aluminium-oxide-and-methyl-vinyl-silicone-polymer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33200.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">557</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">685</span> An Analytical Systematic Design Approach to Evaluate Ballistic Performance of Armour Grade AA7075 Aluminium Alloy Using Friction Stir Processing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lahari%20Ramya%20Pa">Lahari Ramya Pa</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudhakar%20Ib"> Sudhakar Ib</a>, <a href="https://publications.waset.org/abstracts/search?q=Madhu%20Vc"> Madhu Vc</a>, <a href="https://publications.waset.org/abstracts/search?q=Madhusudhan%20Reddy%20Gd"> Madhusudhan Reddy Gd</a>, <a href="https://publications.waset.org/abstracts/search?q=Srinivasa%20Rao%20E."> Srinivasa Rao E.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Selection of suitable armor materials for defense applications is very crucial with respect to increasing mobility of the systems as well as maintaining safety. Therefore, determining the material with the lowest possible areal density that resists the predefined threat successfully is required in armor design studies. A number of light metal and alloys are come in to forefront especially to substitute the armour grade steels. AA5083 aluminium alloy which fit in to the military standards imposed by USA army is foremost nonferrous alloy to consider for possible replacement of steel to increase the mobility of armour vehicles and enhance fuel economy. Growing need of AA5083 aluminium alloy paves a way to develop supplement aluminium alloys maintaining the military standards. It has been witnessed that AA 2xxx aluminium alloy, AA6xxx aluminium alloy and AA7xxx aluminium alloy are the potential material to supplement AA5083 aluminium alloy. Among those cited aluminium series alloys AA7xxx aluminium alloy (heat treatable) possesses high strength and can compete with armour grade steels. Earlier investigations revealed that layering of AA7xxx aluminium alloy can prevent spalling of rear portion of armour during ballistic impacts. Hence, present investigation deals with fabrication of hard layer (made of boron carbide) i.e. layer on AA 7075 aluminium alloy using friction stir processing with an intention of blunting the projectile in the initial impact and backing tough portion(AA7xxx aluminium alloy) to dissipate residual kinetic energy. An analytical approach has been adopted to unfold the ballistic performance of projectile. Penetration of projectile inside the armour has been resolved by considering by strain energy model analysis. Perforation shearing areas i.e. interface of projectile and armour is taken in to account for evaluation of penetration inside the armour. Fabricated surface composites (targets) were tested as per the military standard (JIS.0108.01) in a ballistic testing tunnel at Defence Metallurgical Research Laboratory (DMRL), Hyderabad in standardized testing conditions. Analytical results were well validated with experimental obtained one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AA7075%20aluminium%20alloy" title="AA7075 aluminium alloy">AA7075 aluminium alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20processing" title=" friction stir processing"> friction stir processing</a>, <a href="https://publications.waset.org/abstracts/search?q=boron%20carbide" title=" boron carbide"> boron carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=ballistic%20performance" title=" ballistic performance"> ballistic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=target" title=" target"> target</a> </p> <a href="https://publications.waset.org/abstracts/21635/an-analytical-systematic-design-approach-to-evaluate-ballistic-performance-of-armour-grade-aa7075-aluminium-alloy-using-friction-stir-processing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21635.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">684</span> Studies on the Feasibility of Cow Dung as a Non-Conventional Energy Source</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20Kumar%20Rajak">Raj Kumar Rajak</a>, <a href="https://publications.waset.org/abstracts/search?q=Bharat%20Mishra"> Bharat Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bio-batteries represent an entirely new long-term, reasonable, reachable and ecofriendly approach to produce sustainable energy.

It is evident that heavy metals released in the environment affect the reproductive processes and fertility of animals. Toxic metals affect the male and female reproductive system directly or indirectly. Considering the toxic nature of aluminium and also the major role of secretory products and lipids in sperm maturation, the present study was planned to investigate the effect of aluminium chloride on secretory products like glyceryl phosphoryl choline (GPC), sialic acid, carnitine and acetyl carnitine content and also lipid profiles in the epididymis and spermatozoa of adult rats. Aluminium chloride, 50 mg/kg body weight was administered orally daily for 60 days. 24 hours after the last dose the rats were sacrificed and immediately epididymis was dissected out and spermatozoa was isolated. The weight of the epididymis decreased significantly. GPC and sialic acid content was significantly reduced in the epididymis and not much altered in spermatozoa. Carnitine and acetyl carnitine contents were markedly decreased in the spermatozoa as well as in the epididymis. Aluminium chloride administration caused a marked reduction in total lipid, cholesterol, phospholipids and cholesterol content in epididymis and no significant changes in spermatozoa. Several changes take place in the spermatozoa as they pass through the epididymis. These changes are directly related to the acquisition of fertilizing ability of spermatozoa. From the results, it is evident that aluminium chloride has definite influence on secretory products and lipid profiles in the epididymis. This may eventually have an adverse impact on the fertility of the animal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium%20chloride" title="aluminium chloride">aluminium chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=rat" title=" rat"> rat</a>, <a href="https://publications.waset.org/abstracts/search?q=carnitine" title=" carnitine"> carnitine</a>, <a href="https://publications.waset.org/abstracts/search?q=GPC" title=" GPC"> GPC</a>, <a href="https://publications.waset.org/abstracts/search?q=sialic%20acid" title=" sialic acid"> sialic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=epididymis" title=" epididymis"> epididymis</a>, <a href="https://publications.waset.org/abstracts/search?q=spermatozoa" title=" spermatozoa"> spermatozoa</a> </p> <a href="https://publications.waset.org/abstracts/10221/changes-in-secretory-products-and-lipid-profile-in-the-epididymis-and-spermatozoa-of-rats-induced-by-aluminium-chloride" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10221.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">387</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">682</span> Effect of the Aluminium Concentration on the Laser Wavelength of Random Trimer Barrier AlxGa1-xAs Superlattices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samir%20Bentata">Samir Bentata</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Bendahma"> Fatima Bendahma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have numerically investigated the effect of Aluminium concentration on the the laser wavelength of random trimer barrier AlxGa1-xAs superlattices (RTBSL).

We discuss the impact of the Aluminium concentration associate to the structure profile on the laser wavelengths. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=superlattices" title="superlattices">superlattices</a>, <a href="https://publications.waset.org/abstracts/search?q=correlated%20disorder" title=" correlated disorder"> correlated disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20coefficient" title=" transmission coefficient"> transmission coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20wavelength" title=" laser wavelength "> laser wavelength </a> </p> <a href="https://publications.waset.org/abstracts/15343/effect-of-the-aluminium-concentration-on-the-laser-wavelength-of-random-trimer-barrier-alxga1-xas-superlattices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15343.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">337</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">681</span> Developing an Empirical Relationship to Predict Tensile Strength and Micro Hardness of Friction Stir Welded Aluminium Alloy Joints </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurmeet%20Singh%20Cheema">Gurmeet Singh Cheema</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurjinder%20Singh"> Gurjinder Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Amardeep%20Singh%20Kang"> Amardeep Singh Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aluminium alloy 6061 is a medium to high strength heat-treatable alloy which has very good corrosion resistance and very good weldability. Friction Stir Welding was developed and this technique has attracted considerable interest from the aerospace and automotive industries since it is able to produce defect free joints particularly for light metals i.e aluminum alloy and magnesium alloy. In the friction stir welding process, welding parameters such as tool rotational speed, welding speed and tool shoulder diameter play a major role in deciding the weld quality. In this research work, an attempt has been made to understand the effect of tool rotational speed, welding speed and tool shoulder diameter on friction stir welded AA6061 aluminium alloy joints. Statistical tool such as central composite design is used to develop the mathematical relationships. The mathematical model was developed to predict mechanical properties of friction stir welded aluminium alloy joints at the 95% confidence level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium%20alloy" title="aluminium alloy">aluminium alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title=" friction stir welding"> friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20composite%20design" title=" central composite design"> central composite design</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20relationship" title=" mathematical relationship"> mathematical relationship</a> </p> <a href="https://publications.waset.org/abstracts/52425/developing-an-empirical-relationship-to-predict-tensile-strength-and-micro-hardness-of-friction-stir-welded-aluminium-alloy-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52425.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">502</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">680</span> Hydrogen Production Using Solar Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20M.%20Sakr">I.

Two methods are used and compared for separation between the cathode and anode, which are acrylic separator and polymeric membrane. Further, the effects of electrolyte concentration, solar insolation, and space between the pair of electrodes on the amount of hydrogen produced and consequently on the overall electrolysis efficiency are investigated. It is found that the rate of hydrogen production increases using the polymeric membrane installed between the electrodes. The experimental results show also that, the performance of alkaline water electrolysis unit is dominated by the electrolyte concentration and the gap between the electrodes. Smaller gaps between the pair of electrodes are demonstrated to produce higher rates of hydrogen with higher system efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20production" title="hydrogen production">hydrogen production</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20electrolysis" title=" water electrolysis"> water electrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration" title=" concentration"> concentration</a> </p> <a href="https://publications.waset.org/abstracts/62050/hydrogen-production-using-solar-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62050.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">378</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">679</span> Numerical Investigation for Ductile Fracture of an Aluminium Alloy 6061 T-6: Assessment of Critical J-Integral</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Bensaada">R.

The assessment of fracture toughness is performed with the calculation of Jc (the critical value of J-Integral) through the resistance curves. The study is done using finite element code calculation ABAQUSTM including an elastic plastic with damage model of material’s behaviour. The procedure involves specimens of four different thicknesses and four ligament sizes for every thickness. The material of study is an aluminium alloy 6061-T6 for which the necessary parameters to complete the study are given. We found the same results for the same specimen’s thickness and for different ligament sizes when the fracture criterion is evaluated. <p class="card-text"><strong>Keywords:</strong> <a
