Strength and microstructural properties of mechanically-activated kaolin geopolymers
(Trans Tech Publications, 2012-12)
Kaolin geopolymers exhibit low strength properties due to its plate-like nature which contribute to smaller surface area for geopolymerization reactions. Layered kaolin structure only allows very little, if any, substitution ...
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 ...
Shear strain analysis in FSS microchannel
(AENSI Publications, 2013-10)
Microfluidics has motivated the development of various fields in biological engineering due to its advantages. The favorable benefits of using microfluidicsare being easy to fabricate, requirement of minimal fluid volumes, ...
Characterizations on the effect of processing of polymers blend with petroleum coke (part I)
(Trans Tech Publications, 2013)
Global demand for plastics has grown significantly over the past decades, and will continue to expand with rising income levels in emerging economies; a number of approaches have been used to recycle polymer waste. While ...
Electronic structure, density of electronic states, and the chemical bonding properties of 2,4-dihydroxyl hydrazone crystals (C13H 11N3O4)
(Springer Science+Business Media New York., 2013-05)
Electronic crystal structure, bonding properties, and the electron charge densities of 2,4-dihydroxybenzaldehyde-4-nitrophenylhydrazone (2,4-DHNPH,C 13H11N3O4) crystal are theoretically investigated. Calculations are ...
Properties of chitosan-filled polypropylene (PP) composites: The effect of acetic acid
(Taylor and Francis Group, LLC, 2012-01)
The main objective of this research was to investigate the effect of chitosan content and chemical modification with acetic acid on mechanical and thermal properties of PP/Chitosan. It was found that the tensile strength, ...
Wettability and interfacial phenomena investigations on high-density polyethylene and petroleum coke
(Wiley Periodicals, Inc., 2012-08)
An in-depth wettability and interfacial phenomena investigation was carried out to study interactions between high density polyethylene (HDPE) and petroleum coke. The aim is to investigate the effect of temperature and ...
