Liquid exfoliated MoS2 sheet coupled with conductive polyaniline for gas sensor
(
Qatar University Press
, 2021 , Poster)
Polyaniline (PANI)/MoS2 composites with porous microspheres were prepared by a hydrothermal and in situ polymerization method. The structural, optical, and morphological properties were characterized by X-ray powder ...
Self-healing behavior of epoxy-based double-layer nanocomposite coatings modified with Zirconia nanoparticles
(
Qatar University Press
, 2021 , Poster)
This work reports the self-healing behavior of epoxy reinforced ZrO2 double-layer nanocomposite coatings to alleviate the deleterious effects of corrosion in the oil and gas industry. The corrosion inhibitor (imidazole) ...
Experimental Investigations of Gas Kick for Single and Two-Phase Gas-liquid Flow in near Horizontal Wells
(
Qatar University Press
, 2021 , Poster)
Multiphase flow in pipelines is of great importance and broadly used in several industries for various applications. A multiphase flow is a complex physical phenomenon where more than one phase occurs. In oil and gas ...
Mercury levels in tar mat contaminated beaches and its marine organisms living along the Qatari coasts
(
Qatar University Press
, 2021 , Poster)
One of the pollutants that affects the coastal environment of Qatar is the vast expanse of oil residue ‘tarmats’ deposited on its beaches. The current study is aimed at gauging the concentration levels of total mercury ...
Experimental Investigation of Foam drilling fluid using Visualization Technique
(
Qatar University Press
, 2021 , Poster)
Cutting transport is one of the major factors, which affects the cost, time and quality of drilling operations. Over the years, as the number of directional wells have increased to improve the productivity, it has been ...
Prevalence of Toxigenic Fungi and Mycotoxins in Arabic Coffee: Protective Effect of Traditional Coffee Roasting, Brewing and Microbial Volatiles
(
