Understanding the small world: an insight into the application of transmission electron microscopy in characterizing epitaxial layers
(Penerbit Universiti Malaysia PerlisSchool of Microelectronic Engineering, 2010-04)Transmission electron microscopy (TEM) is an unrivalled technique for observing, characterizing and analyzing almost any type of materials. In physical science, the first observations of defects (i.e. dislocations) by TEM ... -
Temperature cycling analysis for ball grid array package using finite element analysis
(Emerald Group Publishing Limited, 2011)Purpose – The purpose of this paper is to discuss the capability of finite element analysis (FEA) in performing the virtual thermal cycling reliability test to evaluate the reliability of solder joints in a ball grid array ... -
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 ... -
Mechanical and thermal properties of chitosan-filled polypropylene composites: The effect of acrylic acid
(Society of Plastics Engineers, 2011-06)The mechanical properties, morphology, and thermal properties of chitosan-filled polypropylene (PP) composites have been studied. The effect of the chemical modification of chitosan by acrylic acid treatment was also ... -
Development and performance evaluation of hierarchical quadrature amplitude modulation (HQAM) for image transmission over wireless channels
(Institute of Electrical and Electronics Engineers (IEEE), 2011-09-20)Asymmetric modulation techniques like Quadrature Amplitude Modulation system is one of the key techniques in building a broadband mobile communication network because of increasing shortage of wireless communication channels. ... -
Synthesis of finite length multi level sequences for clutter rejection in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-07-24)In radar systems the very low side-lobes that can be achieved with amplitude and phase modulated pulse trains make their use particularly attractive in systems requiring a large dynamic range. Moreover, the excellent ... -
A brief review of layered rock salt cathode materials for lithium ion batteries
(Trans Tech Publications, 2013)Nowadays, many researchers have been studying on the layered rock salt-type structure as cathode materials for the lithium ion batteries. LiCoO2 is the most commonly used cathode material but Co is costly and toxic. Thus, ... -
Ferroelectric and relaxor ferroelectric to paralectric transition based on Lead Magnesium Niobate (PMN) materials
(Trans Tech Publications, 2013)First ferroelectric materials were found in Rochelle salt was in a perovskite structure. Lead Magnesium Niobate (PMN) is a perovskites with a formula of PbMg1/3Nb2/3O3 (PMN) and are typical representatives for most of all ... -
