Tuning the activity of Cu-containing rare earth oxide catalysts for CO oxidation reaction: Cooling while heating paradigm in microwave-assisted synthesis
( Elsevier Ltd , 2018 , Article)(Ce-La-xCu)O2 catalysts with low (3 at.%) and high (10 at.%) Cu content were prepared by conventional microwave (MW) and enhanced microwave methods where air cooling (AC), while heating, was applied. The catalysts were ... -
Tuning the electrical properties of polyaniline by copolymerization with o-bromoaniline
( World Scientific Publishing Co. Pte Ltd , 2017 , Article)Polyaniline, poly(o-bromoaniline) and poly(aniline-co-o-bromoaniline)s have been prepared by chemical oxidative polymerization methods. A series of poly(aniline-co-o-bromoaniline) derivatives has been prepared by the ... -
Tuning the Intermolecular Electron Transfer of Low-Dimensional and Metal-Free BCN/C60Electrocatalysts via Interfacial Defects for Efficient Hydrogen and Oxygen Electrochemistry
( American Chemical Society , 2021 , Article)The development of low-dimensional (LD) supramolecular materials with multifunctional electrocatalytic properties has sparked the attention of the catalysis community. Herein, we report the synthesis of a new class of 0D-2D ... -
Tunisia: The Transformative Media Landscape after the Revolution
( Open Book Publishers , 2021 , Book chapter)The media landscape in Tunisia has witnessed significant transformations since the revolution of 14 January 2011. After decades of being direct controlled and tightly monitored by the dictatorial regimes of Bourguiba and ... -
The Tunisian experience post-2011: The crisis of democratization
( Taylor and Francis , 2023 , Book chapter)Offering a critical counter-narrative that upends the received wisdom about Tunisia’s fledgling democracy, the analysis here challenges existing literature on Tunisia’s democratization since the 2011 revolution, eschewing ... -
Tunisia’s peripheral cities: Marginalization and protest politics in a democratizing country
( Middle East Institute , 2021 , Article)This article investigates Tunisia's southern "periphery within the periphery," drawing on original interviews to examine marginalization and center-periphery relations in the country since the 2011 revolution. Comparisons ... -
Tunisia’s “civic parallelism”: Lessons for Arab democratization
( Taylor and Francis , 2019 , Book chapter)This chapter suggests that knowledge must be situated at the centre of explorations of Arab democratization, primarily through the inclusion of subaltern voices. To demonstrate this line of argument, the chapter addresses ... -
Tunnel Surveying Works: A Technical Challenge of 10 km-long tunnel under the Arabian Gulf-Qatar
( Qatar University Press , 2023 , Conference Paper)The Musaimeer Pump Station & Outfall Tunnel project (MPSO) was constructed as one of the longest Outfall tunnels in the World with a total length of 10.189m and at the same time being the longest undersea tunnel in the ... -
Turbuelence Modeling and Valication to Predict Velocity Profiles in Close-Coupled Five-Gore Elbows
(2021 , Dissertation)This research work aims to validate advanced turbulence modeling techniques used to predict complex flows in close-coupled five-gore elbows and similar complex geometries using data from 2016 ASHRAE RP-1682 (Study to ... -
Turbulence effects on the autoignition of DME in a turbulent co-flowing jet
( Elsevier , 2017 , Article)Dimethyl ether (DME) autoignition in turbulent co-flowing jets with preheated air is studied using the one-dimensional turbulence (ODT) model. We investigate the effects of molecular and turbulent transport on the autoignition ... -
Turbulence Modeling Using Z-F Model and RSM for Flow Analysis in Z-SHAPE Ducts
( Wiley , 2020 , Article)Turbulent flow in Z-shape duct configuration is investigated using Reynolds stress model (RSM) and ζ-f model and compared to experimental results. Both RSM and ζ-f models are based on steady-state RANS solutions. The focus ... -
