Research ArticleOpen accessIn the keywordsProduction and Evaluation of Hydroxyapatite (HAp) Properties of Broiler’s Composite Bone (BCB) Waste at Different Sintering TemperaturesMuhammad Irfan Said, Effendi Abustam, Asdar Gani et al.Bone is one of the perishable livestock wastes, so serious attention is needed. The wastes are produced by Poultry Slaughterhouse (PSh) primarily in the process of separating meat from bone to produce boneless products. The main constituent of bone is the crystals Ca and P, which are the major elements of Hydroxyapatite (HAp). The purpose of this study was to … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 8 May 2018 · 7,711 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of ball milling times on phase formation of Mg0.7Zn0.3Fe2O4Aurawan Rittidech, Panuthat KhotsongkramMg0.7Zn0.3Fe2O4 (MZF) powder was prepared by a solid-state mixed oxide using ball-milling technique. The phase identification of calcined powders was performed using X-ray diffraction technique (XRD). It has been found that MZF powders were successfully obtained for calcination conditions of 800 oC for milling times of 36 h, whereas milling times of 12 h, unreacted ZnO, Fe2O3 and MgO phases … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,324 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis of Nanoparticles of Mixed Oxides Containing Titanium Cerium Silver and Silicon: Phase TransformationAkkarat Wongkaew, Waree Jansome, Supachai Khemchan et al.Problem statement: Titanium dioxide is a well known material using with self-cleaning application. This is due to its properties after exposed to UV light: Superhydrophilicity and photocatalysis. The addition of other oxides could prolong these properties without continuing exposed to UV. However, titanium dioxide phase is essential. In order to obtain these properties, titanium dioxide needs to be in anatase … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,824 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Removal of 4-Chlorophenol and Dichloroacetic Acid in Water Using Ti-, Zr- and Ti/Zr-Pillared Bentonites as PhotocatalystMohamed Houari, Mohamed Saidi, Djamel Tabet et al.Heterogeneous photocatalysis could be alternative remediation technology for water since it does not need the addition of any chemicals and it is suitable for treating low concentrations of pollutant. Although the TiO2 Degussa P 25 is most used photocatalyst its photonic efficiency still low and its recovery from water is considered as an awkward process. In this study the effect … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 7,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATING EFFECTS OF INTRODUCTION OF CORNCOB ASH INTO PORTLAND CEMENTS CONCRETE: MECHANICAL AND THERMAL PROPERTIESAntonio Price, Ryan Yeargin, Ellie Fini, Taher Abu-LebdehThe purpose of this study was to evaluate the benefits of replacing Ordinary Portland Cement (OPC) with Corncob Ash (CCA) blended cements. The cement industry contributes considerable amount of Carbon Dioxide (CO2) emissions into the atmosphere. The main contribution of CO2 emissions from cement production results from the process of creating Calcium Oxide (CaO) from limestone (CaCO3) commonly known as … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 31 Mar 2014 · 9,813 accessesView PDFCite
