Research NotesOpen accessIn the abstractA Study on Fabrication and Structural Characterization of PbS Thin FilmsMustika Wati, Kamsul AbrahaPbS thin films are fabricated from 99.9% PbS powder on glass substrates using the vacuum evaporation method. Some of the samples are then treated in an advanced process called annealing. Samples are annealed in temperatures of 80, 100, 120 and 150°C for two h. Characterization using an X-Ray Diffractometer (XRD) resulted in values of lattice constant of the films ranging … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 20 Nov 2017 · 7,847 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabrication and Mechanical Properties of Glass Fiber/Talc/CaCO3 Filled Recycled PP CompositesUğur Soy, Fehim Findik, Salih Hakan Yetgin et al.Until now, recycling studies brought to the agenda after the rapid increasing of plastic materials in every area and causing those plastics to environmental pollution after discarding them following the utilization. The purpose of recycling plastic waste is to minimize environmental pollution and to create of new resources. To perform the present study, Recycled Polypropylene Granules (RPP) belonging to Polypropylene … …American Journal of Applied Sciences, Vol. 14, Issue 9 · 15 Aug 2017 · 9,364 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Graphene Oxide via Liquid Exfoliation Using Self-Custom-Made Tweeter Piezoelectric Ultrasound Generator and Assisted by Surfactant from Commercial DetergentAchmad Ainul Fikri, Aminah Nur Aisyah, Suhufa Alfarisa, Wipsar Sunu Brams DwandaruRapid progress in nanotechnology requires the production of novel nanomaterials. This study aims to synthesize Graphene Oxide (GO) via the Liquid Exfoliation (LE) method using a self-custom-made tweeter piezoelectric system as the ultrasound generator. Linear Alkylbenzena Sulfonate (LAS) surfactant contained in commercial detergent is used to assist the exfoliation process. This synthesis method is simple, inexpensive and may produce GO … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 3 Nov 2016 · 7,251 accessesView PDFCite
Research ArticleOpen accessIn the abstractDissolution Sintering Technique to Create Porous Copper with Sodium Chloride Using Polyvinyl Alcohol Solution through Powder MetallurgyCynthia Waters, Stephen Ajinola, Mustafa SalihThe main purpose of this paper was to investigate the relative densities, porosities, compression strength and energy absorbed by porous copper (Cu) formed via the dissolution sintering technique using Polyvinyl Alcohol (PVA) solution as a binder with Sodium Chloride (NaCl) as space holder. Porous Cu was fabricated through powder metallurgy route using dissolution sintering technique by mixing Cu with NaCl … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 13 Mar 2016 · 8,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Role of Fly Ash and Silica Fume in the Cement Hydration ProcessLucas Suarez, Taher M. Abu-Lebdeh, Miguel Picornell, Sameer A. HamoushThis research work investigates the effect of fly ash and silica fume on cement paste hydration. Percentages of each additive were selected to replace the cement by volume to be studied at five different ages using water curing and vacuum curing. These percentages were compared alongside a controlled cement paste without additives. Testing was carried out on 350 samples. Analysis … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 12 Mar 2016 · 8,640 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Porous Ti-6Al-4V Mix with Palm Stearin Binder by Metal Injection Molding TechniqueMohamad Ikhwan Jamaludin, Nur Atikah Abu Kasim, Nor Hafiez Mohamad Nor, Muhammad Hussain IsmailGood potential of biocompatibility and excellent mechanical properties, porous Ti-6Al-4V has become a great interest for biomedical applications. In this study, porous Ti-6Al-4V was fabricated by Metal Injection Molding (MIM) using Palm Stearin (PS) and Polyethylene (PE) binder together with sodium chloride (NaCl) as a space holder. Rheological characterization was performed to evaluate the flowability of the feedstocks for injection … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 31 Oct 2015 · 7,564 accessesView PDFCite
Research ArticleOpen accessIn the abstractORGANIC SOL-GEL METHOD IN THE SYNTHESIS AND CHARACTERIZATION OF ZINC OXIDE NANOPARTICLESKeanchuan Lee, Zulhilmi Akmal Saipolbahri, Beh Hoe Guan, Hassan SoleimaniNanosized Zinc Oxide (ZnO) was synthesized using sol-gel method. The nanomaterials with structure were annealed at different temperatures ranging from 500 to 700°C which were chosen based on the Thermogravimetric (TGA) Analysis. The structure and morphology were characterized by Powder X-Ray Diffraction (PXRD) and Transmission Electron Microscope (TEM), respectively. The PXRD shows the increasing tendency in crystallite size when the … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 7 Apr 2014 · 7,296 accessesView PDFCite
