Research ArticleOpen accessEvery word in the titleSynthesis of Zeolite from Aluminium Etching By-Product: the Effect of Reaction Temperature on Crystallinity and Its CO2 Adsorption PropertyKanokorn Hussaro, Supaporn Douglas, Noppadon CheamsawatThe synthesis of zeolite from the by-product of aluminium etching process was investigated. The starting by-product reactant had high aluminium content, 92.17% wt. as Al2O3. Si and Na compositions were adjusted by the addition of sodium metasilicate, in the hydrogel process.The reaction time was fixed at 1 h., while the stirring speed was controlled at 200 rpm. and the temperature … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,524 accessesView PDFCite
Research ArticleOpen accessIn the keywordsINFLUENCE OF ELECTRON BEAM TREATMENT ON THE CRYSTALLIZATION AND THERMAL STABILITY OF LDPE/EPDM BLENDSBhuwanesh Kumar Sharma, Subhendu Ray Chowdhury, P. A. Mahanwar, K. S.S. SarmaThe effect of blend composition and Electron Beam (EB) irradiation on the crystallization and thermal behavior of Low Density Polyethylene (LDPE)/Ethylene-Propylene-Diene elastomer (EPDM) blends had been studied. Melting temperatures were found to remain unchanged upon variation of blend composition as well as irradiation dose. But the degree of crystallinity and Tc (crystallization temperature) were decreased with increase in EPDM content … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 17 Nov 2014 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUse of X-Ray Diffractometry (XRD) for Identification of Fritillaria According to Geographical OriginWang Shujun, Yu Jinglin, Gao WenyuanFritillaria is a traditional Chinese herbal medicine for anti-tussive and expectorant use in China and some other Asian countries. The Fritillaria Chinese medicine material derived from different geographical origins is always difficult to discriminate each other. The objective of the study is to develop a nondestructive and simple method to identify five Fritillaria Chinese materia medica such as Fritillaria thunbergii … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractWettability and Interfacial Tension Alteration of Rare-Earth Doped Yttrium Iron Garnet under Influence of Electromagnetic WavesLau Zhen Yin, Lee Kean Chuan, Beh Hoe Guan et al.Yttrium Iron Garnet (YIG) doped with rare-earth elements have shown to alter the magnetic properties of garnet nanoparticles (NPs), which is believed to have direct influence on the wettability, interfacial tension and viscosity alteration of garnet nanofluids. In this study, Y2.8R0.2Fe5O12 (R = Lanthanum (La), Neodymium (Nd) and Samarium (Sm)) NPs were synthesized by using the sol gel auto-combustion method … …American Journal of Applied Sciences, Vol. 16, Issue 6 · 25 Jul 2019 · 7,684 accessesView PDFCite
Review ArticleOpen accessIn the abstractContinuous Flow Synthesis of Zeolite-A from Coal Fly Ash Utilizing Microwave Irradiation with Recycled Liquid StreamSalman Bukhari, Sohrab RohaniCoal Fly Ash (CFA) was converted to zeolite using continuous microwave reactors while minimizing the wastewater produced during the zeolitization process. At bench scale, a continuous flow tubular microwave reactor was used to explore the effect of microwave irradiation on the crystallinity of the product. The waste water was reused in consecutive runs and Inductively Coupled Plasma (ICP) analysis was … …American Journal of Environmental Sciences, Vol. 13, Issue 3 · 19 Jun 2017 · 7,237 accessesView PDFCite
Research ArticleOpen accessIn the abstractProperties of ZnO:Ga Thin Films Deposited by dc Magnetron Sputtering: Influence of Ga-Doped Concentrations on Structural and Optical PropertiesPutut Marwoto, Edy Wibowo, Dwi Suprayogi et al.ZnO:Ga thin films were deposited on corning glass by dc magnetron sputtering. Influence of Ga-doped concentrations on the structural and optical properties of ZnO:Ga thin films were investigated. The XRD patterns show that the crystallinity of deposited films improved with the increase of Ga concentrations from 1 to 2%, then decrease at 3% Ga concentrations. The optical transmittance of films … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 14 Dec 2016 · 7,477 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural and Dielectrical Properties of Sterilized Human TeethMostafa Fawzy Eissa, Hassan Mohamed El-Shamy, Hassan Saad HanafyProblem statement: This study investigated the changes in crystallinity and dielectrical properties (conductivity) that could be demonstrated in extracted human teeth (enamel and dentin) subjected to γ-radiation at the sterilization dose (25 kGy). Approach: Twenty human third molar teeth were used in the study. Teeth were prepared so forty enamel and dentin samples were obtained. The samples were divided into … …Physics International, Vol. 3, Issue 1 · 20 Dec 2012 · 7,182 accessesView PDFCite
