Ecological and Health Risks Assessment of Potentially Toxic Metals and Metalloids Contaminants
(
Qatar University Press
, 2021 , Poster)
Potentially toxic environmental contaminants, including metals and metalloids, are commonly found in emerging economies. At high concentrations, elements such as As, Cr, and Ni can be hazardous and may lead to various ...
Omega-3 fatty acid-rich fish oil supplementation prevents rosiglitazone-induced osteopenia in aging mice
(
Qatar University Press
, 2021 , Poster)
Rosiglitazone is an effective insulin-sensitizer, however, associated with bone loss mainly due to increased bone resorption, and bone marrow adiposity, and decreased bone formation. We investigated the effect of the ...
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 ...

(
Qatar University Press
, 2021 , Poster)
Salinity is an abiotic influencer to the growth and the efficiency of the algal Symbiodinium that coexists in symbiosis with corals. In light of the high salinity conditions that prevail in the Arabian Gulf including the ...
Germanium Oxide/germanium/ reduced Graphene (GeO2/Ge/r-GO) Hybrid Composite Anodes for Lithium-ion Batteries: Effect of Ge loading on Electrochemical Performance
(
Qatar University Press
, 2021 , Poster)
Hybrid composites between Germanium (Ge) and carbonaceous materials are promising anode materials for Li-ion batteries (LIBs). The mitigation of reduced cycling ability and rate capability allows for the unhindered benefit ...
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 ...
