Research ArticleOpen accessEvery word in the titleUse 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 keywordsSynthesis and Characterizations of MmtO-Copolymer (St-THF) NanocompositeHattab Youcef, Hakiki WahibaNanocomposites are synthesized by one or two polymers and optimized organophilic clay proportions. The aim of Synthesis of the Organophilic clay (montmorillonite) with a two monomers to get a copolytetrahydrofuran- styrene nanocomposite by insitu polymerization. Organophilic montmorillonite (MmtO) was synthesized by ion exchange between Na+ ions in the clay and HDTMAB alkylammonium cations in an aqueous medium. The MmtO were … …American Journal of Applied Sciences, Vol. 16, Issue 10 · 19 Dec 2019 · 7,116 accessesView PDFCite
Research ArticleOpen accessIn the keywordsESR and FT-IR Studies on GeO2 Substituted Lead Vanadate Semiconducting Glass SystemP. Tejeswara RaoA series of Germania-lead-vanadium pentoxide glasses with x=5, 10 and 15 mol% were prepared by melt quenching technique and they were characterized by X-ray diffraction (XRD), Differential scanning calorimetry (DSC), Fourier Transform Infrared (FT-IR) and Electron Spin Resonance (ESR) techniques. X-ray diffraction results reveal that all samples are perfect amorphous in nature. Differential scanning calorimetry results indicate that the substituent … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 19 Apr 2019 · 6,793 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCompositional Analysis on Ancient Bricks from Candi Sungai Mas (Site 32/34), Bujang Valley, KedahZuliskandar Ramli, Nik Hassan Shuhaimi Nik Abd. Rahman, Adnan Jusoh, Mohd. Zobir HusseinProblem statement: The significance of Kampung Sungai Mas as an importance archaeology site in Lembah Bujang was revealed in the year 1979 when a cannel was built along Kampung Sungai Mas area. During the construction study of this cannel, thousands of ceramic pieces from India, Middle East, China, Southeast Asia and Europe was discovered, pieces of glasses from Middle East … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 12 Dec 2011 · 9,839 accessesView PDFCite
Research ArticleOpen accessIn the keywordsX-Ray Diffraction and X-Ray Fluorescent Analyses of Prehistoric Pottery Shards from Ulu KelantanZuliskandar Ramli, Nik Hassan Shuhaimi Nik Abdul Rahman, Adnan Jusoh, Yunus SaumanProblem statement: X-Ray Diffraction (XRD) and X-Ray Fluorescent (XRF) were used in order to obtain mineralogical and elemental composition of seven pottery shards that have been unearthed during the excavation at Peraling Cave and Cha Cave in Ulu Kelantan, Malaysia. Approach: Peraling Cave and Cha Cave were prehistoric sites dating from 10, 000 BC which were inhabited by Hoabinhian people … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 20 Oct 2011 · 7,751 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInvestigation of Nano Structural Changes by Annealing Temperature and Uniform Oxygen Flow on Ti LayersHaleh Kangarlou, Saeid RafizadehProblem statement: Ti films of the same thickness, deposition angle (near normal) and deposition rate were deposited on glass substrates at room temperature under UHV conditions. Approach: Different annealing temperatures 423 K, 523 K and 623 K with uniform 7 cm3 sec-1, oxygen flow, were used to produce titanium oxide layers. Results: Thin film structures were studied using AFM, XRD … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,378 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImproving the Polypropylene-Clay Composite Using Carbon Nanotubes as Secondary FillerSalawudeen T. Olalekan, Suleyman A. Muyibi, Qasim H. Shah et al.Problem statement: Current researches have shown that the thermoplastic-clay nanocomposites have failed to live up to the earlier predictions albeit they have found some niche area of applications. This research work therefore aimed at studying the effect of carbon nanotube as secondary filler on the mechanical properties of polypropylene-clay nanocomposite. Approach: Hybrid polypropylene-clay nanocomposite was prepared in the presence of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,668 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStandardization of Metal-Based Herbal MedicinesArun Sudha, V. S. Murty, T. S. ChandraProblem statement: Standardization of herbal drugs is a burning topic in herbal drug industry today. Standardization is difficult because they are usually mixtures of many constituents and the active principle in most cases is unknown. However it is possible to generate a physico-chemical fingerprint for the standardization of these drugs with reference to authentic drugs, for monitoring variation between preparations … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,904 accessesView PDFCite
