Facile preparation of N-S co-doped graphene quantum dots (GQDs) from graphite waste for efficient humidity sensing
(
Elsevier B.V.
, 2021 , Article)
In this work, graphene quantum dots (GQDs) were prepared from Graphitic waste. The resulting GQDs were evaluated for the potential application for resistive humidity sensors. The resistive humidity sensors were fabricated ...
Synthesis of in situ photoinduced halloysite-polypyrrole@silver nanocomposite for the potential application in humidity sensors
(
MDPI AG
, 2020 , Article)
Halloysite-polypyrrole-silver nanocomposite has been prepared via in situ photopolymerizations of pyrrole in the presence of silanized halloysite and silver nitrate as a photoinitiator. The halloysite nanoclay (HNT) was ...

(
WITPress
, 2014 , Article)
Air pollution is one of the most crucial factors affecting the quality of life and health of increasingly urban populations; a country with a fast-growing economy based on hydrocarbons such as Qatar is no exception. In ...
Effect of annealing temperature on the performance of printable carbon electrodes for perovskite solar cells
(
Elsevier B.V.
, 2019 , Article)
Perovskite solar cells (PSCs) with mesoporous TiO2 electron transport layers have reached >22% efficiency at laboratory scale (<1 cm2), however, these layers are fabricated using spin-coating, which is not conducive ...
