Research ArticleOpen accessEvery word in the titleSpectral and Luminescence Properties of Manganese Doped Sodium Lead Alumino Borosilicate Glass SystemK. Vijaya Babu, A. Subba Rao, K. Naresh Kumar, M. Venugopala RaoNa2O-PbO-Al2O3-B2O3-SiO2 glasses mixed with different concentrations of MnO (ranging from 0.3 to 0.9 mol %) was prepared by melt quenching technique. The samples were characterized by X-ray diffraction technique, Optical absorption and Photo luminescence technique. A prepared glass sample is confirmed by X-ray diffraction spectra. The optical absorption spectra of these glasses exhibited a predominant broad band peak at 21,052 … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 22 Nov 2019 · 7,114 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Y2O3 Additions on Microstructure and Properties of Alumina–Magnesia CeramicsAurawan Rittidech, Pimpun Wisuwan, Thitima PinkhunthodThe purposes of this research are to prepare and investigate the characterization of 0.7MgO-xY2O3-(99.3-x)Al2O3 by varies x at 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0 wt% (AMY). AMY samples were synthesized by solid state reaction under two different sintering methods conventional sintering method (NS) and two stage sintering method (TS). Ceramic samples were sintered by conventional sintering at 1600°C for … …American Journal of Applied Sciences, Vol. 15, Issue 8 · 30 Oct 2018 · 8,029 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Nano-Alumina on Pore Structure and Durability of Class F Fly Ash Self-Compacting MortarEhsan Mohseni, Konstantinos Daniel TsavdaridisIn this study the effect of pore structure on the mechanical properties and durability characteristics of Self-Compacting Mortars (SCM) containing nano-Al2O3 (NA) and class F fly ash are investigated. Al2O3 nanoparticles with the maximum size of 15 nm in three different proportions of 1, 3 and 5% of the binder content were utilized to partially replace the cement. The 25% … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 14 Apr 2016 · 9,472 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCombustion of Bimodal Nano/Micro Aluminum Suspension with New Reaction Rate ModelM. Bidabadi, N. Moallemi, I. Shafieenejad, M. JadidiIn this study a mathematical model for combustion of bimodal particle in lean flow was developed. The difference between structure of flame in this work and previous ones was that, in those flame was divided by five zones and reaction rate was considered to be constant in reaction zones and also zero in post flame zone. In reality it was … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 6,794 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpact of Chemical Coagulants for Oscillatoria sp. Removal from Raw Water on Chemical Coagulation ProcessSaowapak Thammasane, Thaniya KaosolGrowing Oscillatoria sp. in freshwater causes several poisoning episodes of domestic livestock animal and human. The chemical coagulation of raw water using chemical coagulants is very simple and requiring less investment cost on equipment. These experiments used alum and PACl (Polyaluminium chloride) with alum as chemical coagulants for Oscillatoria sp. removal. The Oscillatoria sp. was prepared from Molecular and Cell … …American Journal of Environmental Sciences, Vol. 14, Issue 6 · 14 Dec 2018 · 8,610 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProduction of Bioelectricity Using Single Chamber Microbial Fuel CellAhmad Nawaz, Ram Sharan SinghThe present study addressed the application of sandwich-type air cathode microbial fuel cell (ACMFC) for the production of bioelectricity. Activated carbon was pasted on aluminum mesh for the manufacture of anode and cathode. This electrode design eliminated the requirement for carbon cloth or a metal catalyst, resulting in a cathode with excellent activity for oxygen reduction. The findings demonstrated that … …American Journal of Environmental Sciences, Vol. 19, Issue 2 · 4 Sep 2023 · 5,735 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBootstrap Approach to Correlation Analysis of Two Mineral ComponentsT.O. OlatayoProblem statement: In this article we considered pairs bootstrap through a truncated geometric bootstrap method for stationary time series data. Construction of valid inferential procedures through the estimates of standard error, coefficient of variation and other measures of statistical precision such as bootstrap confidence interval were considered. The method was used to confirm the correlation between Silicon Oxide (SiO2) and … …Current Research in Geoscience, Vol. 2, Issue 1 · 7 May 2013 · 6,589 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAdhesion and Hardness Evaluation of Modified Silicone-Dammar as Natural Coating MaterialsR. Zakaria, A. H. AhmadProblem statement: Dammar is a natural resin that used anciently in varnish production. The use of dammar natural resin in coating is limited by undesirable properties for application in coating where it is considered very brittle. Due to dammar's brittle nature, an aged dammar coating can be easily scratched or abraded. Approach: Dammar natural resin could be modified into Silicone-Dammar … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 20 Mar 2012 · 7,630 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Study of Solar Reflector Efficiency of Parabolic Dual TroughSopa Cansee, Adisak Pattiya, Singthong Pattanasethanon, Worraphan SombutteraProblem statement: The receiver of parabolic dual trough had been designed and built in order to increase efficiency of solar radiation accumulation by using iron-aluminum sheet as an intermediate in receiving heat and it is the study into how to benefit from solar radiation energy.
