(
Qatar University Press
, 2021 , Poster)
The research work deals with the implementation of various chargers used for electric vehicles in the context of Qatar. These chargers are categorized as slow, fast, and super-fast chargers. The electric vehicles not only ...
Effect of UV/ozone treatment on surface hydrophilicity and humidity sensing properties of PVDF-BaTiO3 composite films
(
Qatar University Press
, 2021 , Poster)
In this research work, we have studied the impact of UV/ozone treatment on the hydrophilicity of the PVDF-BaTiO3 nanocomposite film. We have prepared the nanocomposite solution by mixing PVDF (2.5 wt% kept constant) and ...
Liquid exfoliated MoS2 sheet coupled with conductive polyaniline for gas sensor
(
Qatar University Press
