DFT investigation of H2S adsorption on graphenenanosheets and nanoribbons: Comparative study
( Elsevier , 2020 , Article)Graphenenanosheet (GNS), armchair graphenenanoribbon (AGNR), and zigzag graphenenanoribbon (ZGNR) systems were investigated by first principle calculations using the density functional theory (DFT). The DFT calculations ... -
The effect of graphene on the activation energy of grain growth for the nanocrystalline thermoelectric n‑type Bi2Te2.7Se0.3
(2022 , Article)Even though bismuth telluride is frequently produced by mechanical alloying for thermoelectric materials, no data has been published addressing the thermal behavior and activation energy of the milled n-type Bi2Te2.7Se0.3 ... -
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, ... -
PbS/CdS heterojunction quantum dot solar cells
( Springer New York LLC , 2016 , Article)The present work investigates the effects of combination of lead sulfide PbS quantum dots and cadmium sulfide CdS nanoparticles (NPs), with n-type and p-type semiconductors, on the photovoltaic performance of heterojunction ... -
Selective gas sensors using graphene and CuO nanorods
( Elsevier B.V. , 2018 , Article)This work reports on the fabrication of sensitive and selective gas sensors fabricated using graphene and/or copper oxide (CuO) nanorods. Herein, three batches of sensors were produced based on graphene/SiO2/Si, CuO nanorods, ...
