Research ArticleOpen accessIn the abstractEffect of Carboxyl-Functionalized Single Walled Carbon Nanotubes on the Interfacial Barrier Height of Malachite Green Dye Based Organic DeviceSudipta Sen, Nabin Baran ManikIn this study, we have estimated the interfacial barrier height (ɸb) of Indium Tin Oxide (ITO) coated glass/Malachite Green (MG) dye/Aluminium (Al) based organic device and subsequently we have also observed the effect of carboxylfunctionalized SWCNT (COOH-SWCNT) on the ɸb. Presence of COOH-SWCNT reduces the interfacial barrier height as SWCNT acts as filler and provides easy path for charge percolation. … …Physics International, Vol. 10, Issue 1 · 31 Jul 2019 · 12,391 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Cement Chemistry on the Performance of Cement Stabilized Tropical Lateritic SoilOdumade Adegboyega Oduniyi, Ezeah Chukwunonye, Charles Nnamdi Ezugwu, Ekeoma EmmanuelChemical composition affects overall performance of cement on other materials such as when used in concrete or for stabilization of lateritic soil. This research studied the influence of chemical composition of three Portland cement types represented as samples A, B and C on engineering performance when mixed with laterite under tropical environmental conditions.The Lateritic soil sample classified according to AASHTO … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 May 2018 · 8,804 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAcquisition and Research of the p-3C-SiC Epitaxial Layers Based on the 6H-SiC Semi-Insulating SubstratesLebedev Alexander Alexandrovich, S.P. Lebedev, E.V. Bogdanova et al.By now we know almost nothing about works on production of p-3C-SiC. Probably, it is due to the fact that the basic acceptor impurity (aluminium) accumulates on the interfaces of the twins and other structural defects in the 3C film and it is electrically neutral. We managed to produce the highly doped layers p-3C based on the conducting substrates of … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 27 May 2015 · 6,466 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRemoving Boron from an Aqueous Solution Using Turmeric Extract-Aided Coagulation-FlocculationAzhar Abdul Halim, Nur Hanani Thaldiri, Normah Awang, Mohd Talib LatifProblem statement: Boron exists in an environment naturally either through weathering of rocks or volcanic activity but due to anthropogenic activity, boron had been distributed widely into our surroundings. Boron was a problematic pollutant due to the difficulty to remove it from the water. Turmeric which had been widely used as a spice and traditional medicine, were investigated to determine … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 15 Jun 2012 · 8,329 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Polishing of Cutting-Edge Polymer-on-Glass for Pigtailing PreparationMohammad Syuhaimi Ab-Rahman, Fazlinda Ab-Aziz, Noor Azie Azura Mohd Arif et al.Problem statement: The high quality of cutting-edge surface is important in optical waveguide's efficiency. The perfect polishing of end surface is significant to deliver the best quality of light waves and minimize the device losses such as insertion loss and return loss. Hence, this research is concern on the parameters in polishing SU-8 polymer to increase the efficiency of waveguide. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 9,148 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSynthesis of Al3Fe5O12 Cubic Structure by Extremely Low Sintering Temperature of Sol Gel TechniqueNoorhana Yahya, Ramadan A.H. Masoud, Hanita Daud et al.Problem statement: Fabrication of nano materials particularly nano inductors at low sintering temperature remains a challenge. This study was carried out as our initial response to obtain a nano-size inductors, which is aluminium iron garnet using low sintering temperature. Approach: The aluminum iron garnet (Al3Fe5O12) nano crystals were prepared by sol-gel technique. The starting solution is a mixture of iron … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,563 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNon Destructive Tests of Structural Bonds by Guided Ultrasonic Waves: Effect of a Surface Pretreatment or a Localized DefectValentina Vlasie, Martine RousseauThe aim of this study was to propose a non destructive method to test the mechanical quality of a bond aluminium/epoxy/aluminium. Thus, for each aluminium/epoxy interface, an intermediate interface modelling between a simple geometrical interface and an interphase (3D material medium), i.e. a 2D material medium. In order to describe the surface stresses, we introduce the surface free energy (the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,883 accessesView PDF Cite
