Performance of organic dyes for textile cotton fabric
(Universiti Malaysia Perlis (UniMAP), 2020-12)
This research was focus on optimum dye concentration for self-cleaning properties for uncoated and coated dyed cotton fabrics through physical and mechanical properties. The dyed cotton fabrics were coated with aqueous ...
Theoretical demonstration of elastic wave guiding in a Pillar-Based phononic crystal slab
(Universiti Malaysia Perlis (UniMAP), 2020-12)
We demonstrated theoretically the wave guiding of elastics waves in a two-dimensional (2D) phononic crystal (PnC) slab. The simulation model based on the Finite Element Method (FEM) was used to calculate the dispersion ...
Structural Equation Modelling (SEM) of risk factors for mathematical anxiety in tertiary students
(Institute of Engineering Mathematics (Universiti Malaysia Perlis), 2020-12)
Mathematics anxiety or mathematics phobia is a general term for several disorders that will cause panic attacks, nervousness, and social anxiety, which potentially gave negative outcomes when faced with any situation related ...
Application of double natural transform to one-dimensional heat equations
(Institute of Engineering Mathematics, Universiti Malaysia Perlis, 2020-12)
This paper presents the application of double Natural transform method to solve one-dimensional heat equations 𝜕𝑈(𝑥,𝑡)𝜕𝑡=𝜕2𝑈(𝑥,𝑡)𝜕𝑥2+𝑓(𝑥,𝑡) under the given conditions. The Double Natural Transform (DNT) ...
Synthesis and characterisation of oleic acid coated Fe3O4 nanoparticles in Poly Alpha Olefin oil based nanofluid for heat transfer applications
(Universiti Malaysia Perlis (UniMAP), 2021-01)
Nanofluids are heat transfer liquids with dispersed nanoparticles. Ultrafine nano sized particles, having diameter <100 nm, are suspended in a conventional base fluid to constitute a nanofluid. The present study highlights ...
Facile fabrication of screen-printed carbon electrodes for electrochemical sensors
(Universiti Malaysia Perlis (UniMAP), 2021-01)
Carbon pastes were applied in fabricating screen-printed carbon electrodes (SPCEs) for versatile electrochemical analyses. The electrochemical behaviour of the homemade system, consists of a working electrode, a counter ...
Nanoswitch-based on ring-opening of 1,3-cyclohexadiene molecule
(Universiti Malaysia Perlis (UniMAP), 2021-01)
In the framework of the density functional theory, in combination with the method of non-equilibrium Green functions (DFT+NEGF), electric transport characteristics of nanoswitch-based on ring opening of the 1,3-cyclohexadiene ...
Preparation of CdSe quantum dots using laser ablation technique for Dye-Sensitized Solar Cell
(Universiti Malaysia Perlis (UniMAP), 2021-01)
Organic dyes are known to be widely used in the manufacture of dye-sensitized solar cells. However, theoretical screening does not play an essential role in dyes design. This work seeks to improve the conversion efficiency ...
Comparative simulation of DC and AC performances of Al0.26Ga0.74N/GaN HEMT with BGaN Back Barrier
(Universiti Malaysia Perlis (UniMAP), 2021-01)
This paper discusses the influence of BGaN layer on the structure of Al0.26Ga0.74N/ B0.02Ga0.98N /GaN HEMT with T- Gate. The use of BGaN back barrier on this device enhances confinement of the electron in the device. We ...
Evaluation of mechanical properties on Vulcanized SMRCV-60 and ENR-25 of flexible-rigid body vibration isolator
(Universiti Malaysia Perlis (UniMAP), 2020-05)
This paper presents the evaluation of tensile test results on mechanical properties of local natural rubber called the standard Malaysian rubber constant viscosity-60 and the epoxidized natural rubber 25% with different ...
