Research ArticleOpen accessAll words, across the recordDesign and Modeling the Prosthetic Foot from Suitable Composite MaterialsHasan Saad Mohammed, Jasim Mohammed SalmanThis work concerns developing a composite material, which can be used in manufacturing prosthetic feet with a reasonable cost and satisfying mechanical properties. The characteristics were investigated by mechanical tests of tensile properties and Charpy impact strength. The study of date palm wood and its effects on the mechanical properties of polyethylene have received little attention. It was found that … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 12 Sep 2020 · 7,602 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSTRUCTURAL AND OPTICAL STUDIES OF CONDUCTING PANI/CuS NANOCOMPOSITES ON NANOCRYSTALLINE ZINC-OXIDE THIN FILMM. A. Sangamesha, K. Pushpalatha, G. L. ShekarIn this article, a p-n heterostructure diode was developed by incorporating the synthesised nanocomposite of CuS/PANI into the hallow network of ZnO thin film deposited on the glass substrate, which hitherto not reported. Analyses of the obtained heterostructure were carried out using XRD, FT-IR, UV-Visible and SEM. The penetration, bonding and the interaction of the nanocomposite with ZnO was investigated … …Current Research in Nanotechnology, Vol. 5, Issue 1 · 15 Aug 2014 · 7,044 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPositron Annihilation Study on Nickel and Iron Nano-Particles in Natural Rubber CompositesEmad Hassan AlyProblem statement: The effect of Ni and Fe nano-particles as a filler on the free volume properties Of Natural Rubber (NR) was studied using Positron Annihilation Lifetime Spectroscopy (PALS). Approach: The PAL measurements revealed that the free volume properties are strongly affected by the amount and type of filler. Results: Particularly speaking, the free volume fraction dramatically decreased by increasing … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 7,625 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAC Analysis of PEO10LiCF3SO3 Polymeric Material for Memory Storage ApplicationMahmoud Z. IskandaraniProblem statement: Intelligent systems that need to accurately represent human brain requires analogue devices such as a neural switch that processes decision signals and can actually remember the made decision. Polymeric material such as PEO10LiCF3SO3, which previously used in high energy, long life storage batteries, is used here to implement the principle of storage with the required analogue memory. Approach: … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,981 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordImmobilization of Lipase from Candida Rugosa on Palm-Based Polyurethane Foam as a Support MaterialRoila Awang, Mohd Rafaei Ghazuli, Mahiran BasriLipase from Candida rugosa was immobilized onto palm-based polyurethane foam (PU), which the polymer was pre-soaked in co-immobilized agent. The activities of PU-immobilized lipase were tested by the esterification reaction of oleic acid and oleyl alcohol in hexane. The PU-immobilized lipase was then characterized in term of its thermal, operational and storage stability. The optimum temperature for native and PU-immobilized … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,478 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPolymer in Agriculture: a ReviewFrancesco Puoci, Francesca Iemma, Umile Gianfranco Spizzirri et al.In agricultural field, polymers are widely used for many applications. Although they were used, in the first time, just as structural materials (inhert polymers), in the last decades functionalized polymers revolutionized the agricultural and food industry with new tools for several applications. Smart polymeric materials and smart delivery systems helped the agricultural industry to combat viruses and other crop pathogens, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 21,407 accessesView PDF Cite
