Production of metal-oxide nanoclusters using inert-gas condensation technique
(
Elsevier B.V.
, 2017 , Article)
Inert-gas condensation is a novel technique that can be used to produce nanoclusters for different applications. In the present work, dc sputtering combined with inert-gas condensation were used to produce copper oxide ...
Characterization of H2S gas sensor based on CuFe2O4nanoparticles
(
Elsevier Ltd
, 2017 , Article)
Copper ferrite (CuFe2O4) nanoparticles were prepared by the sol-gel auto-combustion method and used to construct a conductometric gas sensor in this work. The as-prepared CuFe2O4 nanoparticles were annealed at 500 °C and ...
Selective hydrogen gas sensor using CuFe 2 O 4 nanoparticle based thin film
(
Elsevier B.V.
, 2016 , Article)
Hydrogen gas sensors based on CuFe2O4 nanoparticle thin films are presented in this work. Each gas sensor was prepared by depositing CuFe2O4 thin film on a glass substrate by dc sputtering inside a high vacuum chamber. ...
Engineering the band gap of BN and BC2N nanotubes based on T-graphene sheets using a transverse electric field: Density functional theory study
(
Elsevier
, 2022 , Article)
A new class of nanotubes formed by rolling boron nitride (BN) and boron carbonitride (BC2N) sheets in the form of T-graphene is suggested in this work. The structural and electronic properties of these nanotubes, named ...
Fabrication of Selective Sensors for Hg2+ Traces in Water Using Graphene Decorated with Metal Nanoclusters
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Mercury metal is released into water by different sources including sewage industrial waste, thus, it can enter human food chain. It is considered one of the most harmful pollutant of heavy metals since it is non-biodegradable, ...
Sensitive SO2 gas sensor utilizing Pt-doped graphene nanoribbon: First principles investigation
(
Elsevier Ltd
, 2021 , Article)
The objective of this work is to seek a highly sensitive gas sensor for the detection of sulfur dioxide (SO2) by investigating the impacts of passivation as well as metal doping of armchair-edge graphene nanoribbon (AGNR) ...
First principle study of transition metals codoped MoS2 as a gas sensor for the detection of NO and NO2 gases
(
Elsevier B.V.
, 2021 , Article)
Exposure to nitrogen oxides (NOx) has been reported to seriously affect the respiratory systems. More precisely, breathing NOx may lead to the appearance of asthma symptoms, and may also result in the infection with asthma ...
Co-doped zigzag graphene nanoribbon based gas sensor for sensitive detection of H2S: DFT study
(
Academic Press
, 2021 , Article)
In this work, we present a highly sensitive gas sensor for the detection of poisonous hydrogen sulfide gas (H2S) based on copper and zinc co-doped zigzag graphene nanoribbon (Cu/Zn-ZGNR). The electronic properties as well ...
Computational study of metal doped graphene nanoribbon as a potential platform for detection of H2S
(
Elsevier Ltd
