(Universiti Malaysia Perlis, 2013)In the present work, a direct precipitation method using wet chemical reaction was used to synthesize pure and Sb doped ZnO nanoparticles. The zinc nitrate and sodium hydroxide were used as staring materials or precursors ... -
Characterization of LUSI mud volcano as geopolymer raw material
(Trans Tech Publications, 2012)The mud of mud volcano samples were collected from an eruption site named 'LUSI' (Lumpur "mud" -Sidoarjo), East Java, Indonesia for characterization. Analysis showed that, the major constituents of mud are SiO 2 and Al 2O ... -
Characterizations of biocompatible and bioactive hydroxyapatite particles
(Elsevier B.V., 2013)The most common gene vectors used are virus based (viral gene vectors). These possess high immunological risk, so a non-viral gene vector maybe preferable. Nanocrystalline hydroxyapatite, HAp [Ca10(PO 4)6(OH)2] is an example ... -
Chemical & Mineralogical Properties of Fly Ash
(Malaysian Nuclear Society, 2007)Fly ash is the finely divided mineral residue resulting from the combustion of coal in electric generating plants. Fly ash consists of inorganic, incombustible matter present in the coal that has been fused during combustion ... -
Comparison of original and sintered LUSI mud from East Java, Indonesia as raw material for making a geopolymer
(American Scientific Publishers, 2013-01)This paper presents the characterization of LUSI mud from East Java, Indonesia, as a potential raw material for making a geopolymer. Two types of LUSI mud were analyzed, i.e., original LUSI mud and LUSI mud that had been ... -
Electronic structure of quaternary chalcogenide Ag₂In₂Ge(Si)S₆ single crystals and the influence of replacing Ge by Si: Experimental X-ray photoelectron spectroscopy and X-ray diffraction studies and theoretical calculations
(American Scientific Publishers, 2013-04)Ag₂In₂GeS₆ and Ag₂InSiS₆ are two interesting quaternary-sulfide single crystals. Starting from our previous investigation on Ag₂In₂GeS₆ single crystals, the Ag₂In₂SiS₆ is investigated here. We demonstrate the effect of ... -
