Towards Developing a Hybrid Nonlinear Vibration Energy Harvester for Remote Sensing Applications: A Design and Optimization Study
(
Qatar University Press
, 2021 , Poster)
A novel design of a hybrid piezoelectric-electromagnetic harvester for vortex-induced vibration applications inside a pipe-flow is proposed. The piezoelectric energy harvester is modeled with a macro-fiber composite with ...
Oil Spill Index (OSI) to Sentinel-2 satellite data: QU in International Contribution
(
Qatar University Press
, 2021 , Poster)
An Oil Spill Index (OSI = (B3+B4)/B2) was developed and applied to Sentinel-2 optical satellite data of the European Space Agency (ESA) to map marine oil spills using spectral absorption characters of spectral bands of the ...
Effect of Silicon Nitride and Graphene Nanoplatelets on the Properties of Aluminum Metal Matrix Composites
(
Qatar University Press
, 2021 , Poster)
This research work aims at investigating the influence of a fixed content of silicon nitride (Si3N4) and varied contents of graphene nanoplatelets (GNPs) on the physical and mechanical properties of Al-Si3N4-GNPs composites. ...
Surface waves generated by shamal and easterly winds off Qatar
(
Qatar University Press
, 2021 , Poster)
Waves in the Arabian Gulf are primarily controlled by the regional winds, for example, shamal winds during winter and early summer. Though Gulf wave characteristics have been heavily utilized for the design of offshore ...
Facile and Novel LiAlO2 Film Electrodes for Energy Efficient Li recovery from Seawater Reverse Osmosis (SWRO) Brine
(
Qatar University Press
, 2021 , Poster)
Concentration of Li in seawater is too low at 0.17 ppm despite its high content altogether with a reported 230 billion tons. Hence, seawater is not a practical source to recover Li from; Li is largely extracted by solar ...
Bio-Inspired Fabrication of Ultrafiltration Membranes incorporating Polydopamine Functionalized Graphene Oxide Nanoparticles
(
Qatar University Press
, 2021 , Poster)
Novel PSF composite UF membranes incorporating low loadings of polydopamine-functionalized graphene oxide particles (rGO-PDA) were fabricated and investigated. The functionalization was confirmed using FTIR-UATR, Raman ...
Preliminary Investigation of Heavy Metals in Deposited Dust on Roadside Sidr Leaves
(
Qatar University Press
, 2021 , Poster)
Urban pollution has different forms; one of them is air pollution by natural sources such as dust storms or by anthropogenic sources such as traffic, whereas both are considered among the most risky environmental problems ...
Military Fuel Cell-Based Vehicles: Modular Power DC-DC Converter System
(
Qatar University Press
, 2021 , Poster)
Electric Vehicles (EVs) have attracted researchers' attention to further develop and enhance this strategic area. Compared to fuel-based vehicles, EVs are more in demand nowadays due to their high performance and modern ...
Gearless Powertrain for Electric Vehicles
