Satellite mapping and stabilization of the aeolian deposits of QAFCO site 5/6
(
Qatar University Press
, 2021 , Poster)
Aeolian processes produce vast areas of sand and dunes in the arid region and need monitoring since they are encroaching land and degrading infrastructures. In this study, we used the satellite data of ASTER and mineral ...
Origin of TPHs and PAHs in the marine sediment nearby oil and gas extraction sites on the west coast of Qatar
(
Qatar University Press
, 2021 , Poster)
Total Petroleum Hydrocarbons (TPHs) and Polycyclic Aromatic Hydrocarbons (PAHs) are priority pollutants, which are known to be associated with petroleum products. They are released into the marine environment via accidental ...
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)
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 ...
Feminization of hawksbill turtle hatchlings in the twenty-first century at an important regional nesting aggregation
(
Qatar University Press
, 2021 , Poster)
Projected climate change is forecasted to have significant effects on biological systems worldwide. Marine turtles in particular may be vulnerable, as the sex of their offspring is determined by their incubating temperature. ...
