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 ...
