Research ArticleOpen accessIn the keywordsA General Formula for Ion Concentration-Dependent Electrical Conductivities in Polymer ElectrolytesMahardika Prasetya Aji, Masturi, Satria Bijaksana et al.Problem statement: The aim of this study is to develop a model for describing the effect of ion concentration on the electrical conductivity of polymer electrolytes by considering two mechanisms simultaneously: Enhancements of ion concentration and amorphous phase. Approach: The problems based on new observations in polymer electrolyte when ion concentration in the polymer electrolytes was increased, both the fraction … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 30 Mar 2012 · 8,616 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbout Glassy Amorphous Metal InjectionRaffaella Aversa, Relly Victoria Petrescu, Antonio Apicella et al.The paper aims to present studies on the melt flow, melting and rheology of melting in a super-cooled metastable liquid metal, which is injection molded, of the Zr44-Ti11-Cu10-Ni10-Be25 alloy, which can induce selective crystallization. In this process, high Be-velocities were observed, Cu and Ni atoms that crystallized differently in superficial bulk metallic bulk liquids. It wants to highlight and analyze … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 22 Jan 2018 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractNear Critical Carbon Dioxide Sorption Induced Crystallization in PETAversa Raffaella, Apicella AntonioNear critical carbon dioxide sorption equilibria at 50°C and pressures up to 40 atms are analyzed and interpreted on the basis of the multiple sorption mechanisms possible in a glassy amorphous and semi crystalline polymer. Varying the penetrant-polymer testing temperature and external pressure it is possible to meet the full range of possible sorption behavior, from ideal Fickian diffusion to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 18 Jun 2016 · 8,006 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE HIGH VOLUME REUSE OF HYBRID BIOMASS ASH AS A PRIMARY BINDER IN CEMENTLESS MORTAR BLOCKCheah Chee Ban, Noor Shazea Ahmad Nordin, Part Wei Ken et al.High Calcium Wood Ash (HCWA) and Pulverised Fuel Ash (PFA) are by-products from the wood biomass and coal energy production which are produced in large quantity with combined annual production of 500 million tonnes. This poses a serious problem for disposal of the waste material especially at places where land is scarce. The prescribed study was aimed to examine the … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 29 May 2014 · 7,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis 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 abstractSelected Soil Morphological, Mineralogical and Sesquioxide Properties of Rehabilitated and Secondary ForestsB. T. Saga, O. H. Ahmed, A. S. Jamaluddin et al.Problem statement: The tropical rain forests in Southeast Asia have been characterized by several researchers. However empirical data on soil characteristics under degraded forest land in tropical rain forest and rehabilitated program are limited. A study was conducted to evaluate the soil morphology, mineralogical and sesquioxide properties of a rehabilitated degraded forest land (19 years after it was planted with … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,016 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeochemical Distribution of Trace Metals and Assessment of Anthropogenic Pollution in Sediments of Old Nakagawa River, Tokyo, JapanH.M. Zakir, Naotatsu Shikazono, Kazuo OtomoThe geochemical distributions of cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb) and zinc (Zn) were examined in sediments collected from Old Nakagawa River (NR), Tokyo, Japan. A widely used 5-step sequential extraction procedure was employed for the fractionation of the metals and the concentrations were measured in the liquid extracts by inductively coupled plasma mass spectrometry (ICP-MS). The association … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Boron Carbonitride (BCN) Thin Films Deposited by Radiofrequency and Microwave Plasma Enhanced Chemical Vapor DepositionM.A. Mannan, M. Nagano, K. Shigezumi et al.Boron carbonitride (BCN) thin films with a thickness of ~4 µm were synthesized on Si (100) substrate by radiofrequency and microwave plasma enhanced chemical vapor deposition using trimethylamine borane [(CH3)3N.BH3)] as a molecular precursor. The microstructures of the films were evaluated using field emission scanning electron microscopy (FE-SEM) and X-ray diffractometry (XRD). Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,371 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGlassy Amorphous Metal Injection Molded Induced Morphological DefectsRaffaella Aversa, Daniela Parcesepe, Relly Victoria V. Petrescu et al.Melt rheology in injection molded metastable supercooled liquid metal of Zr44-Ti11-Cu10-Ni10-Be25 alloy may induce selective crystallizations. High mobility Be, Cu and Ni atoms have been observed to differently crystallize in bulk metal glassy supercooled liquids. Here, we analyze the result of morphological microscopic observation conduct on Bulk Metallic Glass (BMG) with composition of a commercial liquid metal alloy (LM001B).
