Research ArticleOpen accessEvery word in the titleELECTROLYSIS OF SWINE MANURE EFFLUENTS USING THREE DIFFERENT ELECTRODES Fe-Fe, Al-Al AND Fe-AlS. Rahman, M. S. BorhanSwine effluent with high organic strength need to be treated to make it suitable for applying to crop/pasture fields, or discharging to any waterways. Electrocoagulation is a relatively simpler and cheaper technique over biological and chemical treatment methods currently used to treat high-strength industrial and municipal wastewater. The performance of an electrocoagulation system mainly depends on the pH, Electrical Conductivity … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 4 · 9 Oct 2014 · 9,177 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudy on Infrared PbS Detector Prepared Using Copper Electrodes of Printed Circuit BoardHariyadi Soetedjo, Gunawan S. Prabowo, Darsono BahrunCopper layers of Printed Circuit Board (PCB) have been used as electrodes for PbS infrared structure detector to introduce low cost and simple in preparation. PbS deposition as an active layer detector has been prepared for a few micrometers in thickness using an evaporation technique under vacuum pressure at 10-6 Torr. Photoconductivity phenomenon has been observed from the measurement when … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 11 Jun 2013 · 6,566 accessesView PDFCite

Ab Rahman, Anuar Bin KassimProblem statement: Glassy carbon electrode GCE was modified with different microparticles to increase the efficiency of analysis Mn2+ in blood samples by cyclic voltammetry and applied for the detection of trace Mn(II) by oxidation process. Approach: The structure and composition of the modified GCE processed by using Carbon Nanotubes CNT and C60 to produce two modified electrodes CNT/GCE and C60/GCE, … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,489 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUse of 2D Multi Electrodes Resistivity Imagining for Sinkholes Hazard Assessment along the Eastern Part of the Dead Sea, JordanAbdallah S. Al-Zoubi, Abd El-Rahman A. Abueladas, Rami I. Al-Rzouq et al.Sinkholes and subsidence are natural phenomena can be occurred in shallow geology sediments at different regions in the world. Sinkholes assessment is one of the most difficult near subsurface investigations. Geophysical prospecting is appropriate method to determine environmental and geotechnical problems. 2D multi electrodes resistivity imagining with Wenner-Schulmberge array was conducted within active sinkholes area. The objective of the survey … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,049 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHarvesting Chaetoceros Calcitrans and Nannochloropsis sp. Via ElectroflocculationNitin Raut, Dinesh Kumar Saini, Reena VaidyaThe efficiency of harvesting the algal biomass plays a dominant role in the production of biodiesel from microalgae. On a commercial scale the choice and efficiency of the harvesting techniques may be a deciding factor for economic viability of this renewable energy source. The highly energy intensive centrifugation and filtration process are followed by flocculation for harvesting microalgae. Therefore the … …American Journal of Applied Sciences, Vol. 14, Issue 9 · 12 Apr 2017 · 7,719 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiosensor Based on Xanthine Oxidase for Monitoring Hypoxanthine in Fish MeatHelena S. Nakatani, Luciane V. dos Santos, Cristiano P. Pelegrine et al.An amperometric enzyme electrode for the detection of hypoxanthine in fish meat is described. The hypoxanthine sensor was prepared from xanthine oxidase immobilized by covalent binding with glutaraldehyde and bovine serum albumin on a nafion-coated platinum disc electrode. The responses for hypoxanthine were obtained in 0.1 mol L-1 phosphate buffer (pH 7.0), at potential of 600mV vs Ag/AgCl. This biosensor … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 8,597 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Biosensors to Analyse a Soldier’s Stress LevelJosé Miguel Martinho Silva, Ricardo A. Marques Lameirinhas et al.Currently and increasingly, biosensors are present in our daily lives, even if tendentiously and imperceptibly. As such and given their importance, the scientific community is clearly interested in making progress in this research field. This study is part of the study of biosensors using pre-gelled electrodes and was focused on the analysis of the ability to extract information on the … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 1 Mar 2024 · 4,972 accessesView PDFCite
Research ArticleOpen accessIn the abstractPoly(3,4-Ethylenedioxythiophene):Poly(4-Styrenesulfonate) Anode for ITO-Free Organic Light-Emitting DiodesKeanchuan Lee, Martin WeisOrganic Light-Emitting Diodes (OLEDs) devices using flexible substrates are envisioned for flexible, low-cost and roll-to-roll mass production. However, transparent conductive oxides such as indium tin oxide (ITO) do not fit the requirements of flexible devices, fabricated without vacuum-based technology. Hence, conductive polymer poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) has been proposed as an alternative approach to transparent conductive electrodes. The secondary doping of PEDOT:PSS … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 8 Jan 2018 · 7,590 accessesView PDFCite
