The Catalytic Thermo-oxidative Decomposition of Glimepiride
( Qatar University Press , 2021 , Poster)In this study, the thermal decomposition of glimepiride, a common antidiabetic drug, was analyzed in the presence of N2 and O2 and various metal oxide catalysts. The analysis was conducted using TGA. The results showed ... -
The efficacy of two household cleaning and disinfecting agents on Lentil (Lens culinaris Medik) and Faba bean (Vicia faba) seed germination
( Qatar University Press , 2021 , Poster)A germination test of Vicia faba and Lens culinaris seeds under the effect of bleach and vinegar was conducted for seven days, and the observations were recorded daily. The completely randomized design (CRD) was used to ... -
The Influence of Qatari Dust on the Element Composition of Marine Plankton
( Qatar University Press , 2021 , Poster)The Exclusive Economic Zone (EEZ) of Qatar is affected by extreme dust and extensive industrialization, making it an ideal location to examine influences of coastal processes on biological activity, which greatly affects ... -
The Separation of Emulsified Water/Oil Mixtures through Adsorption on Plasma-Treated Polyethylene Powder
( Qatar University Press , 2021 , Poster)This work addresses the preparation and characterization of efficient adsorbents for tertiary treatment (oil content below 100 ppm) of oil/water emulsions. Powdered low-density polyethylene (LDPE) was modified by radio-frequency ... -
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 ... -
Towards Sustainable Management of Coastal and Offshore Islands in Arabian Gulf Typology: Sensitivity Analysis, Ecological Risk Assessment of Halul and Al-Alyia Islands
( Qatar University Press , 2021 , Poster)The great majority of marine ecosystems in Qatar are in fast decline and nearing collapse, where most ecosystem has lost the biological and economic functionality. Aiming to support the decision makers in the management ... -
Understanding the electrochemical performance of LiNi0. 5Mn1.5O4 coated with Yttria and distributed over graphene nanosheets as cathode in li-ion batteries
( Qatar University Press , 2021 , Poster)LiNi0.5Mn1.5O4 is a promising cathode material for lithium-ion batteries with a high-voltage spinel structure. A microwave-assisted chemical co-precipitation method was used to synthesize Y2O3 coated quasi-spheres of ... -
Variability of Physical and Biogeochemical Parameters in the Exclusive Economic Zone of Qatar
( Qatar University Press , 2021 , Poster)The oceanographic data collected along a transect in the Exclusive Economic Zone (EEZ) of Qatar during late summer (September 2014) and winter (January 2015) have been analyzed to investigate the spatial and temporal ...
