- PublicationThe Effect Of Annealing On Random Lasing In Zinc Oxide Nanorods Grown By Chemical Bath Deposition(2019-04)Maad Tazri, Nur 'IzaziOne dimensional ZnO nanostructure have been extensively studied due to its potential application in electronic and optoelectronic devices. The work presented here utilizes ZnO nanorods prepared by CBO method on pretreated glass substrate.
- PublicationRandom Laser Action In Zinc Oxide Nanorodspreparedbychemicalbath Deposition(2018-09)Alias, Nor FazrinaRecently photon localization effects that give rise to random lasing in ZnO have been widely studied. However the fabrication method required complicated and high cost system. Thus an alternative method is necessary to consider. This study aimed to fabricate ZnO nanorods using low cost yet robust via chemical bath deposition. In this work, ZnO nanostructures were grown onto ZnO seeded glass substrates with different ZnO seeding thickness.
- PublicationThe Development Of Light Emitting Diode (Led)-Based As A Baby-Friendly Device For Treatment Of Neonatal Jaundice(2018-09)Zainudin, Nadira SyuhadaSixty percent of newborns are jaundiced in their first two weeks oflife for their liver is immature and unable to cope with the production of bilirubin. Phototherapy treatment is proven and widely known to treat hyperbilirubinemia. The common light sources used in conventional phototherapy device are special blue fluorescent tubes, compact fluorescent tubes (CFT), halogen spotlights and fibre optic blankets. However, the conventional device is capacious, expensive and cost involved in periodical maintenance. Hence, the idea ofBiliBaju which based on LED is to develop a low cost, mobile, and baby-fiiendly phototherapy device, and promising the same or better effectiveness in treating neonatal jaundiced.
- PublicationEmpirical Modelling And Experimental Investigation On Absorption Spectra Of Colloidal Metal Nanoparticles And Quantum Dots Suspended In Ionic Surrounding Media(2019-04)Mehrdel, BaharakThis study investigates the influence of the nanoparticle size and refractive index of non-absorbent ionic surrounding media on the optical absorption spectra of noble metal nanoparticles (Au, Ag; excited emission) and semiconductor quantum dots (CdSe/ZnS; spontaneous emission) designed for sensing application.
- PublicationDetection Of Subsurface Geological Features Using Selected Geophysical Techniques(2018-10)ArisonaThis study aimed (i) to simulate synthetic model using selected geophysical techniques buried subsurface, (ii) to characterize the subsurface geological features based on field data and (iii) to validate the measured physical parameter using statistical analysis.
