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 abstractEffect of Film thickness on the Electrical and Structural Properties of CdS: In Thin FilmsShadia J. Ikhmayies, Riyad N. Ahmad-BitarPolycrystalline CdS:In thin films were prepared by the Spray Pyrolysis (SP) technique on glass substrates at a substrate temperature Ts= 490°C. The effect of film thickness on the electrical and structural properties of the films was investigated through the analysis of the I-V plots, x-ray diffraction spectra (XRD) and the scanning electron microscope (SEM) images. The conductivity of the films … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 6,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Processing on the Electrical Properties of Spray-Deposited SnO2:F Thin FilmsShadia J. Ikhmayies, Riyad N. Ahmad-BitarHighly transparent SnO2:F thin films were produced by the Spray Pyrolysis (SP) technique to be used as forcontacts in the home made CdS/CdTe solar cells. Films of thickness 100-200 nm were prepared at substrate temperatures in the range 380-480°C. To improve the electrical properties of the films, annealing in nitrogen atmosphere at 400°C and etching by HNO3 were tried. The … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,002 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Charaterization of Magnesium Zinc Ferrites as Electromagnetic SourceNoorhana Yahya, Ami Salwani Mohamad Nor Aripin, Azizuddin A. Aziz et al.Fabrication of Mg1-XZnXFe2O4 (where x = 0.2, 0.3, 0.4 and 0.5) samples using a conventional technique is reported. Oxides of magnesium, zinc and iron with purity of about 99.99% were mixed with distilled water in a milling machine for 12 hours. They were then filtered and presintered at 1250°C and sintered at 1350°C for 10 h in air. The phase … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 8,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Preparation and Investigation of Magnetic Properties of Magnesium Zinc ferritesA. Rittidech, N. Sinthorn, A. NoisaguanMg0.7Zn0.3Fe2O4 (MZF) is a ferrites material, displaying interesting magnetic properties. It has a wide range of magnetic coils and electronic devices. In this research, MZF ceramics was prepared by solid state reaction route and interested on sintering temperature that have effective on phase formation of MZF, microstruce and magnetic properties. The phase identification of ceramic ferrites was performed using X-ray … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,470 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect 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 abstractPreparation of Magnetic Paper from Kenaf: Lumen Loading and in situ Synthesis MethodC. H. Chia, S. Zakaria, S. Ahamd et al.Magnetic papers have been successfully prepared from unbleached kenaf (hibiscus cannabinus) kraft pulps via the lumen loading and in situ synthesis process. The lumen loading method allows the magnetic fillers to be introduced into the lumen of fibres and at the same time leaving the external surfaces free from filler, resulting the better inter-fibre bonding and subsequently its papermaking properties … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,514 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSpectral 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 accessAll words, across the recordUse 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
