Research ArticleOpen accessIn the abstractPorosity Analysis in Porous Brass Using Dual ApproachesRyan Yeargin, Rob Ramey, Cindy WatersThe goal of this research is to produce porous samples for various applications such as heat exchangers, filters and radiation shields. The level of porosity is an important objective yet the level of confidence in two main methods (hand calculations and microscopic analysis) is not high. This work will compare porosity values obtained from traditional hand calculations against analysis from … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 25 Feb 2016 · 8,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Clean-Green Synthesis of Platinum Nanoparticles Utilizing a Pernicious Weed Lantana (Lantana Camara)Musthafa O. Mavukkandy, Sudip Chakraborty, Tasneem Abbasi, Shahid A. AbbasiA rapid, reproducible single step method is proposed for synthesizing platinum nanoparticles using an invasive weed lantana (Lantana camara, L). The method involves mixing of platinum (VI) solution, lantana leaf extract and ascorbic acid in appropriate concentrations and keeping the mixture at 95°C for 8 min. The collective action of ascorbic acid and leaf extract reduced the chloroplatinic acid to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 23 Feb 2016 · 10,447 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Marine Clay-Supported Nano Zero Valent IronHo Kuok How, Wan Zuhairi Wan YaacobThis study reports the preparation and characterization of marine clay nano zero valent iron (MC+nZVI) where marine clay acts as the composite material. Marine clay was air dried and pulverized before used. Basically, MC+nZVI was synthesized by chemical reduction method. The materials synthesized were left oven dried overnight at 50°C. The obtained materials were characterized by Field Emission Scanning Electron … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 26 Jun 2015 · 7,124 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval of Copper from Aqueous Solution using Tunisian ClayN. Boujelben, S. Gharab, F. Bouhamed et al.Natural adsorbents such as clay was used to replace expensive imported synthetic adsorbents. In this study, Scanning Electron Microscopy (SEM), Infrared spectroscopy and X-ray diffraction techniques were used to characterize the used sorbent (clays C). Batch experiments were performed to evaluate the effects of contact time, solution pH and temperature on copper removal onto used sorbent from aqueous solution. Equilibrium … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 15 Jun 2015 · 7,182 accessesView PDFCite
Research ArticleOpen accessIn the abstractFacile Synthesis of AgCl Hollow Nanospheres for Enhanced Photocatalytic PropertiesJing Chen, Yuling Zhao, Xinhui Liu et al.AgCl hollow nanospheres have been synthesized successfully via a hard-template approach using silica nanospheres as hard template for the first time. The phase, size and morphology of the as-prepared AgCl were investigated by X-Ray Diffraction (XRD), Field-Emission Scanning Electron Microscopy (FESEM); which reveals that the cubic AgCl hollow nanospheres with a cell constant a = 5.549 Å are 220 nm … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 22 May 2015 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractComposition Dependent Structural and Thermal Properties of SM2O3 Doped Zinc Fluoroborate GlassesSudha D. Kamath, Akshatha Wagh, M.P. AjithkumarGlasses based on Sm3+ doped zinc fluoroborate have been synthesized and characterized. Formation of glass has been investigated in the 30 ZnF2-20 TeO2-(50-x) B2O3-x Sm2O3 matrix. Fast quenching is required to prevent melt crystallization and adequate heat treatment to diminish thermal stress, which results in an efficient amorphous material. The Differential Scanning Calorimeter (DSC), Scanning Electron Microscopy (SEM), Energy Dispersive … …Energy Research Journal, Vol. 4, Issue 2 · 15 Jul 2014 · 7,244 accessesView PDFCite
Research ArticleOpen accessIn the abstractBONE MEAL AS ALTERNATIVE TREATMENT FOR ACIDIC AND METAL CONTAMINATED ACID MINE DRAINAGE WATER EFFLUENT: LAB SCALECarolyn Payus, Olga David, Moh Pak YanThe typical methods of treatment for acidic and metal contaminated water effluent such as the Acid Mine Drainage (AMD) will always focus on either civil engineering methods, such as disposal, excavation, drainage and encapsulation or process based technologies such as effluent washing and treatment. These techniques are not environmental friendly, costly and unsustainable, thus environmental damaging. Nowadays, there is a … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 3 Mar 2014 · 7,979 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Mode of Action of Antibacterial Components from Melastoma malabathricum Linn LeavesMourouge Saadi Alwash, Nazlina Ibrahim, Wan Yaacob AhmadThe present study aimed to assess the antibacterial activity of the methanol extract of Melastoma Malabathricum Leaves (MMML), active fraction of M. Malabathricum Leaves (ML5) and isolated kaempferol-3-O-(2",6"-di-O-p-trans-coumaroyl)-β-glucopyranoside (Kf) and to describe the preliminary mode of action against Gram-positive and Gram-negative bacteria. The MMML extract was fractionated by Vacuum Liquid Chromatography (VLC) to afford M. malabathricum Leaves fractions (ML1-ML6) of … …American Journal of Infectious Diseases, Vol. 9, Issue 2 · 18 Jun 2013 · 12,621 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation of Nitrate and Phosphate Removing Bacteria from Various Environmental SitesS. DebRoy, S. Das, S. Ghosh et al.Problem statement: Nitrate and phosphate are two major pollutants due to anthropogenic activity like excessive use of fertilizers in agriculture.
