Optical and Structural Properties of ZnO:Au Nanocomposite Thin films
(Universiti Malaysia Perlis (UniMAP), 2018-07)
Zinc Oxide (ZnO) nanoparticles were mixed carefully with gold (Au) nanoparticles. These chemical-compounds were used to make nanocomposite thin films by using the technique of spray pyrolysis. This work studies the XRD ...
Removal of Oxidative Debris from Chemically Functionalized Multi‐walled Carbon Nanotube (MWCNT)
(Universiti Malaysia Perlis (UniMAP), 2018-01)
Oxidized multi‐walled carbon nanotubes (MWCNTs) were prepared by functionalizing
MWCNTs with nitric acid (70%). In order to remove the oxidative debris, in which
partially attached onto the outer layer of MWCNTs side ...
Effect of Laser Energy on the Structure of Ni46–Ti50–Cu4 Shape-Memory Alloy
(Universiti Malaysia Perlis (UniMAP), 2018-10)
The structural and physical properties of nickel–titanium–copper shape-memory alloy and the effect of laser irradiation on the alloy were investigated in this study. The alloy was prepared using the powder metallurgy method. ...
Synthesis and Characterization of Structural, Magnetic and Electrical Properties of Ni–Mn–Zn Ferrites
(Universiti Malaysia Perlis (UniMAP), 2018-01)
Polycrystalline ferrites (NiXMnZn1−XFe2O4) were synthesized by a conventional ceramic
method and sintered at 1100°C for 4 hours. The structure and surface morphology of the
samples were characterized by X‐ray diffraction ...
Effects of Series Resistance and Frequency on the Capacitance/ Conductance –Voltage C/G-V Characteristics of Au/GaN/GaAs and Au/GaAs Diodes
(Universiti Malaysia Perlis (UniMAP), 2018-10)
In order to analyze the effect of the presence of the GaN layer and series resistance, the
electrical characteristics of the Au/GaAsand Au/GaN/GaAsdiodes are investigated. The
study is realized by a nitridation process ...

(Universiti Malaysia Perlis (UniMAP), 2018-01)
The influence of dielectric nanoparticles in an amplifier is still actively sought in many
research laboratories. This paper presents the effect of doped nanoparticle namely
magnesium in fiber amplifiers. Phase separation ...
An Innovative Method for Measuring the Optical Band Gap of Oxidized Surface Layer of Aluminum Tablets based on Absorption Spectra
(Universiti Malaysia Perlis (UniMAP), 2018-01)
This research highlight an innovative method for calculating the optical band gap of thin
layers of aluminum oxide resulting from the surface oxidation of non‐transparent
samples of aluminum. The aluminum samples were ...
Modelling of Silicon based Electrostatic Energy Harvester for Cardiac Implants
(Universiti Malaysia Perlis (UniMAP), 2018-01)
The concept of energy harvesting using the ability of heart to develop an acceptable
amount of power for its natural operation (up to 10W) could address the power
source requirements of leadless pacemakers. This paper ...
Design and Preparation of Low Absorbing Antireflection Coatings Using Chemical Spray Pyrolysis
(Universiti Malaysia Perlis (UniMAP), 2018-10)
Transmission of laser optical elements has been increased when Indium tin oxide (ITO) thin film of relatively high index with different content of Sn was used to prepare ultra thin antireflection coating(ARC's) utilizing ...
