A Aziz,Hong Ngee Lim,S. H. Girei,Mohd Hanif Yaacob,Mohd Adzir Mahdi,Nay Ming Huang,Alagarsamy Pandikumar +6 more
TL;DR: In this article, a silver nanoparticle-incorporated reduced graphene oxide (Ag/rGO) nanocomposite-based tapered optical fiber sensor was successfully fabricated for the sensing of ethanol in an aqueous medium.
Journal ArticleDOI
Room temperature ammonia sensing using tapered multimode fiber coated with polyaniline nanofibers.
S.A. Ibrahim,Norizah Abdul Rahman,M. H. Abu Bakar,S. H. Girei,Mohd Hanif Yaacob,Harith Ahmad,Mohd Adzir Mahdi +6 more
TL;DR: An ammonia sensor composed of a tapered multimode fiber coated with polyaniline nanofibers that operates at room temperature (26°C) and the highest sensitivity is achieved when the diameter is reduced to 20 µm.
Journal ArticleDOI
Dynamic Response of Tapered Optical Multimode Fiber Coated with Carbon Nanotubes for Ethanol Sensing Application
A. A. Shabaneh,S. H. Girei,P. T. Arasu,Mohd Adzir Mahdi,Suraya Abdul Rashid,Suriati Paiman,Mohd Hanif Yaacob +6 more
TL;DR: The developed sensors showed high sensitivity, repeatability and fast responses (<55 s) towards ethanol, and when the developed sensor was exposed to different concentrations of ethanol, the sensor reflectance reduced proportionally.
Journal ArticleDOI
Reflectance response of tapered optical fiber coated with graphene oxide nanostructured thin film for aqueous ethanol sensing
A. A. Shabaneh,S. H. Girei,P. T. Arasu,Wan Baihaqi Wan Ab Rahman,Ahmad Ashrif A Bakar,A. Z. Sadek,Hong Ngee Lim,Nay Ming Huang,Mohd Hanif Yaacob +8 more
TL;DR: In this paper, the performance of a tapered multimode fiber tip coated with graphene oxide (GO) nanostructured thin film towards aqueous ethanol with different concentrations is investigated.
Journal ArticleDOI
Tapered optical fiber coated with graphene based nanomaterials for measurement of ethanol concentrations in water
S. H. Girei,Atafat A. Shabaneh,Hong Ngee-Lim,Mohd Nizar Hamidon,Mohd Adzir Mahdi,Mohd Hanif Yaacob +5 more
TL;DR: Tapered optical fibers coated with graphene and graphene oxide (GO) as the active layer for ethanol sensing were reported in this article, which showed better performance with 80 % towards ethanol concentration of 5 % when compared to graphene-coated sensor with 40 % absorbance change towards ethanol with similar concentrations.
