Kaolin-based geopolymers with various NaOH concentrations
(Springer Verlag, 2013-03)
Kaolin geopolymers were produced by the alkali-activation of kaolin with an activator solution (a mixture of NaOH and sodium silicate solutions). The NaOH solution was prepared at a concentration of 6-14 mol/L and was mixed ...
Numerical analysis of velocity profile in a FFS microchannel
(AENSI Publisher All rights reserved, 2013-10)
Manipulation of the fluid flow behavior in microfluidic with precision technique is crucial to satisfy the needs of miniaturized systems. Velocity measurement is one of the physical phenomena plays significant role to ...
Heat dissipation analysis under natural convection condition on high power LED
(AENSI Publisher All rights reserved, 2013-10)
As the technology downscales with superior power and increased package density, the thermal effects of the high power LED are significant. Thus, the operating junction temperature of the high power light emitting diodes ...
Mechanical properties and fracture behaviour of coconut fibre-based green composites
(Foundation for Materials Science and Engineering “Serban Solacolu”, 2012)
This paper presents the influence of natural fibre content on the mechanical properties of coconut fibre based-green composites. The mixture ratio of cement:sand by weight was fixed at 1:1. Coconut fibre was used as ...
Nutritional properties of edible bird nest
(Asian Economic and Social Society, 2013-06)
Edible bird nest (EBN) is a dried glutinous secretion from the salivary glands of several different swiftlet species. It is widely consumed as a health food due to its high beneficial effects to human health and has been ...
Influence of different exchange correlation potentials on band structure and optical constant calculations of ZrGa2 and ZrGe2 single crystals
(Elsevier B.V., 2013-10)
The all-electron full potential linearized augmented plane wave method was used to solve the Kohn Sham DFT equations. We have employed different approximations for the exchange correlation potentials, namely: LDA, GGA and ...
Low density fibrous material surface light reflectance analysis
(AENSI Publisher All rights reserved, 2013-10)
The light based surface finishing of most product measurement is an important feature in the industries. In this paper, a lab fabricated tester for investigation on the quality of low density paper which was represent by ...
Influence of oxide molar ratios on kaolin geopolymers
(American Scientific Publishers, 2013-12)
Oxide molar ratios are the main key parameter determining the performance of a kaolin geopolymers. The kaolin composition and various mixture proportions will lead to different oxide molar ratios in geopolymer system. In ...
Chemical modification of chitosan-filled polypropylene (PP) composites: The effect of 3-aminopropyltriethoxysilane on mechanical and thermal properties
(Taylor & Francis Group, 2011-01)
Chitosan was used as filler in polypropylene (PP) polymer. In order to improve compatibility between chitosan and PP, chitosan was chemically modified with 3-aminopropyltriethoxysilane (3-APE). The results show that the ...
FSS microchannel fluid flow profile investigation at high and low Re number
(AENSI Publisher All rights reserved, 2013-10)
The fundamental understanding of dynamic fluid flow behavior in different geometry channel is crucial due to transport phenomena influence on the key design and process control of the microfluidic systems. Recently, the ...
