X-ray photoelectron spectrum, X-ray diffraction data, and electronic structure of chalcogenide quaternary sulfide Ag2In 2GeS6: Experiment and theory
(Springer Science+Business Media, LLC, 2013-02)
We report measurements of the X-ray diffraction and X-ray photoelectron spectrum on single crystals of Ag2In2GeS6. We also present first principles calculations of the band structure and density of states using the ...
Microstructural analysis of geopolymer and ordinary Portland cement mortar exposed to sulfuric acid
(Revista De Materiale Plastice, 2013-09)
The vulnerability of ordinary Portland cement (OPC) concrete to acidic attack is a worrying subject regarding the future durability of this binder. On the other side of binder's technology, the new technology of cement ...
LED heat dissipation study using different Cu slug size
(AENSI Publisher All rights reserved, 2013-10)
High power light emitting diodes (LEDs) have significant contribution in illumination industry due exceptional advantages in terms of low power consumption, superior reliability, prolonged life time and high efficiency. ...
Study on the properties of oil palm trunk fiber (OPTF) in cement composite
(Trans Tech Publications, 2013)
Properties of oil palm trunk fiber reinforced cement composite were investigated in this study. Oil palm trunk fiber was used to improve the properties of cement composite. It was found that increasing in oil palm trunk ...
Characterization of porous aluminum fabricated via sintering- dissolution process (SDP)
(Trans Tech Publications, 2013)
Porous metals that have open pores structure with low density and light weight properties are suitable to be used in many engineering applications. In this work, the porous aluminum was fabricated via sintering dissolution ...
Study on physical and chemical properties of fly ash from different area in Malaysia
(Trans Tech Publications, 2013-12)
Fly ash is residue from the combustion of coal which widely available in worldwide and lead to waste management proposal. Moreover, the use of fly ash is more environmental friendly and save cost compared to OPC. Fly ash ...
Mechanical performances of fly ash geopolymer bricks
(American Scientific Publishers, 2013-01)
Geopolymer is a new class of three-dimensionally networked amorphous to semi-crystalline alumino-silicate materials, and first developed by Professor Davidovits in 1978. Geopolymers can be synthesized by mixing alumino-silicate ...
Effect of spot welding current and cycles on the mechanical properties of welded galvanized steel sheets
(Trans Tech Publications, 2013)
Studies on the effects of welding current and cycles were carried on the galvanized steel sheets using spot welding. The welding currents used were 3 kA, 5 kA 6 kA and the welding cycles were 4, 6 and 8. Tensile shear and ...
High power LED heat dissipation analysis via copper diamond slug
(AENSI Publisher All rights reserved, 2013-10)
The emergence of high power light emitting diode as a novel electronic based light source is due to its vast advantage in terms of optical efficacy, low power consumption and enhanced life time. However, the performances ...
Lightweight fly ash-based geopolymer concrete
(Trans Tech Publications, 2013)
The experiments of this study were preformed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) using normal sand as a fine aggregate and expanded clay as lightweight aggregate. The LWAGC ...
