Research ArticleOpen accessPhrase in the titleEffect of Partial Orientation in [100] Direction on the Magnetic Properties of Co-Ferrite Prepared from Nano ParticlesH. M. El-SayedChemical co-precipitation method was used for the preparation of Co-ferrite nano particles. The particle size was about 18 nm. A magnetic anisotropy of Co-ferrite could be increased by applying an external magnetic field during the pressing of the nano particles before the final sintering. This anisotropy enhanced the squareness and the coercivity of investigated samples. …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,220 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePositron 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 PDFCite
Research ArticleOpen accessIn the abstractBiogenic Silver Nanoparticles Produced by Bacteria Isolated from University Campus Environment Soil Samples in Ras Al KhaimahPooja Shivappa, Grisilda Vidya Bernhardt, Sheela Haridas, Michael V MagaogaoSilver is observed to be comprised of a huge percentage ofsilver oxide and the utilization of silver and silver salts is in practicesince ancient human civilization. Silver nanoparticles remain to be potentialantifungal, antibacterial, anti-inflammatory, and antiviral agents. Further, itis demonstrated that silver nanoparticles have been involved in arresting thegrowth of several bacterial species thereby reducing their harmful effects.Micro-organisms are being … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 5 Sep 2022 · 5,870 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Sintering Mechanisms for Additive Manufacturing of Conductive TracesJasmine McKenzie, Salil DesaiAdditive Manufacturing (AM) processes enable the fabrication of miniaturized and flexible devices on complex geometries. This paper explores a hybrid additive manufacturing technology that integrates micro-extrusion and PICO-jetting methods. Conductive slurries and colloidal inks were optimized for their rheological properties to aid their precise deposition. A variety of conductive materials which include carbon, silver, nano-particle silver and nickel were deposited … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 5 May 2018 · 8,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnderstanding Hybrid Additive Manufacturing of Functional DevicesSantosh Kumar Parupelli, Salil DesaiThe fabrication of electronic components in three-dimensional space is critical for building multifunctional devices. Traditional manufacturing approaches are limited to building planar device configurations. In order to address this limitation, our group has developed a novel hybrid additive manufacturing process that can deposit multi-material patterns on conformal substrates. This direct-write approach involves the combination of microextrusion, pico jet and laser … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 8,154 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Nano Silica for Improving Mechanical Properties of Hardened Cement PasteIntisar Kuli, Taher M. Abu-Lebdeh, Elham H. Fini, Sameer A. HamoushThe influence of adding Nano particles of silicon dioxide (SiO2) on cement pastes was studied for both water and vacuum curing methods. Specimens made up of different percentage of Nano Silica were tested at different ages ranging from 3-56 days. The effect of (5-20 nm) Nano-Silica on the strength development of Nano-cement was determined using Material Tests System (MTS). The … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 9,084 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbout Nano Fusion and Dynamic FusionFlorian Ion T. Petrescu, John Kaiser CalautitHot fusion is currently a difficult goal to accomplish due to the high temperatures required, which are difficult to achieve and also to be maintained. For these reason, it is much easier to try to achieve cold fusion, or a combined method. In this paper, the author will briefly present some original relationships for setting up a theoretical model for … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 12 Mar 2016 · 11,303 accessesView PDFCite
Research ArticleOpen accessIn the abstractInsulating Properties of Low Density Polyethylene/Alumina NanocompositesSi-Jiao Wang, Jun-Wei Zha, Yun-Hui Wu et al.High-Voltage Direct Current (HVDC) cable has become an important factor in the development of HVDC transmission. However, there are still difficulties such as space charge distribution in the development of HVDC cables. In this study, Low Density Polyethylene (LDPE) nanocomposites filled with nano alumina (nano-Al2O3) particles with or without modification were prepared by employing melting blend method. The results show … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 4 Jul 2015 · 7,936 accessesView PDFCite
