TL;DR: In this paper, a carbon dioxide gas sensor from the room-temperature reduction of graphene oxide via hydrogen plasma was developed, where the hydrogen plasma contains radicals and atoms which give dissociation energies for oxygen functional groups, which is capable of reducing the graphene oxide.
Journal ArticleDOI
Piezoresistive effects in controllable defective HFTCVD graphene-based flexible pressure sensor.
Muhammad Aniq Shazni Mohammad Haniff,Muhammad Aniq Shazni Mohammad Haniff,Syed Muhammad Hafiz,Khairul Anuar Abd Wahid,Zulkarnain Endut,Hing Wah Lee,Daniel C. S. Bien,Ishak Abdul Azid,Mohd Zulkifly Abdullah,Nay Ming Huang,Saadah Abdul Rahman +10 more
TL;DR: The sensor performance is strongly dominated by the defect density in the graphene, where graphene with the highest defect density exhibited an almost four-fold sensitivity as compared to that deposited at 1000 °C.
Journal ArticleDOI
Electrochemical Performance of Supercapacitor with Stacked Copper Foils Coated with Graphene Nanoplatelets
TL;DR: A method for enhancing the energy density of a device through the parallel stacking of five copper foils coated on each side with graphene nanoplatelets, which yielded an optimum specific energy density and a specific power density.
Journal ArticleDOI
Piezoresistive Effect in Plasma-Doping of Graphene Sheet for High-Performance Flexible Pressure Sensing Application.
Muhammad Aniq Shazni Mohammad Haniff,Syed Muhammad Hafiz,Nay Ming Huang,Saadah Abdul Rahman,Khairul Anuar Abd Wahid,Mohd Ismahadi Syono,Ishak Abdul Azid +6 more
TL;DR: The high sensitivity and good robustness demonstrated by the plasma-treated graphene sensor suggest a promising route for simple, low-cost, and ultrahigh resolution flexible sensors.
Journal ArticleDOI
Nitrogen-doped multiwalled carbon nanotubes decorated with copper(I) oxide nanoparticles with enhanced capacitive properties
Muhammad Aniq Shazni Mohammad Haniff,Syed Muhammad Hafiz,Khairul Anuar Abd Wahid,Zulkarnain Endut,Mohd Ismahadi Syono,Nay Ming Huang,Saadah Abd Rahman,Ishak Abd Azid +7 more
TL;DR: In this paper, the enhanced capacitive properties of a copper(I) oxide nanoparticle (Cu2O NP)-decorated multiwalled carbon nanotube (MWCNT) forest with nitrogen (N) doping were investigated.
