Physicochemical properties of pyrolitic carbon black from waste tyres
(Trans Tech Publications, 2014)
Waste tyres which are mainly generated from automotive industries have become a major environmental problem to the local authorities, the tyre industries and tyre dealer. When tyres are no longer usable due to worn-out, ...
NaAuS chicken-wire-like semiconductor: electronic structure and optical properties
(Elsevier, 2014-01)
The electronic structure, charge density and optical properties of NaAuS a chicken-wire-like semiconductor was calculated using full potential linear augmented plane wave based on density functional theory. The Ceperley-Alder ...
Review of the characterization and processing of palm ash as a geopolymer composite
(American Scientific Publishers, 2013-01)
Malaysia is the world's largest producer and exporter of palm oil and it produces a million tons of palm oil waste annually. Palm ash is a by-product from the use of palm oil shells and palm oil bunches, which are used to ...
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 ...
Mechanical, morphological and thermal properties of chitosan filled polypropylene composites: The effect of binary modifying agents
(Elsevier B.V., 2013)
This work investigates the effects of the binary modifying agents-organosolv lignin and acrylic acid, on the mechanical and thermal properties of chitosan-filled polypropylene (PP) composites. We analyse the mechanical and ...
Feasibility study on composition and mechanical properties of marine clay based geopolymer brick
(Trans Tech Publications, 2014)
Geopolymer is an inorganic polymer performed in synthesis process of an aluminosilicate material which activated by alkaline activator solution. Marine clay, considered to be a waste substance which have an important ...
Optimization of solids-to-liquid and alkali activator ratios of calcined kaolin geopolymeric powder
(Elsevier Ltd, 2012-12)
This paper investigates the effect of S/L and alkali activator ratios on the synthesis of geopolymeric powder. Geopolymeric powder was synthesized by applying geopolymerization process. By adopting the concept of "just ...
Wettability analysis on platinum deposited wafer after reactive ion ecthing using SF6+argon/CF4+argon gaseous
(AENSI Publisher All rights reserved, 2013-10)
Wettability in microfluidic has direct influence to its fluid flow channels. This paper investigates the variable parameters that affect the wetability in terms of contact angle on a Platinum deposited wafer after reactive ...
Calcined kaolin geopolymeric powder: Influence of water- to geopolymeric powder ratio
(Trans Tech Publications, 2012-07)
This paper describes the synthesis of calcined kaolin geopolymeric powder from the alkaline activation of calcined kaolin followed by solidification and pulverizing process. The geopolymeric powder was used by just adding ...
Processing and characterization of calcined kaolin cement powder
(Elsevier Ltd, 2012-05)
Abstract
This paper aimed at investigating the possibility of calcined kaolin to produce cement powder that could be an alternative to Portland cement by applying geopolymerization process. Cement paste was firstly made ...
