Surfactant/organic solvent free single-step engineering of hybrid graphene-Pt/TiO2 nanostructure: Efficient photocatalytic system for the treatment of wastewater coming from textile industries
(
Nature Publishing Group
, 2018 , Article)
In this study, hybrid graphene-Pt/TiO2 nanostructure were synthesized by single-step, inexpensive and surfactant/organic solvent free route; hydrothermal technique. The physicochemical properties of hybrid graphene-Pt/TiO2 ...
Comparison of antibody immune responses between BNT162b2 and mRNA-1273 SARS-CoV-2 vaccines in naïve and previously infected individuals.
(
Oxford University Press
, 2021 , Article)
Two mRNA vaccines, Pfizer-BNT162b2 and Moderna-mRNA-1273, obtained the Emergency Use Listing by WHO for preventing COVID-19. However, little is known about the difference in antibody responses induced by these two mRNA ...
Rational synthesis, characterization, and application of environmentally friendly (polymer–carbon dot) hybrid composite film for fast and efficient UV-assisted Cd2+ removal from water
(
Springer
, 2020 , Article)
Background: Carbon dots (CDs) are of particular interest in numerous applications. However, their efficiency for heavy metal removal from wastewater was not yet reported. Herein, we rationally synthesized CDs from petroleum ...
A reservoir bubble point pressure prediction model using the Adaptive Neuro-Fuzzy Inference System (ANFIS) technique with trend analysis
(
Public Library of Science
, 2022 , Article)
The bubble point pressure (Pb) could be obtained from pressure-volume-temperature (PVT) measurements; nonetheless, these measurements have drawbacks such as time, cost, and difficulties associated with conducting experiments ...

البصائر
, 2021 , Article)
من بين أهم عوائق النهضة، تلك الهزيمة النفسة التي تسكن كثيرا من صناع القرار وقادة المجتمع والفكر في بلداننا الإسلامية، أو ما يسميها ابن خلدون بولع المغلوب بتقليد الغالب، أو ما سماه مالك بن نبي القابلية للاستعمار. وما كان ...
Self-healing behavior of epoxy-based double-layer nanocomposite coatings modified with Zirconia nanoparticles
(
Elsevier
, 2021 , Article)
This work reports the self-healing behavior of epoxy-based double-layer nanocomposite coatings designed to mitigate corrosion in various industrial applications. Zirconia (ZrO2) nanoparticles were used as a carrier to load ...
Fabrication of low emissivity paint for thermal/NIR radiation insulation for domestic applications
(
Elsevier
, 2022 , Article)
Recently, low-emissivity paint has gained more importance than commercial paints. Low emissivity (Low-E) Paint also termed as a coating for radiation control, in which the emissivity of radiations of longer waves are reduced ...
Genomic Characterization and Annotation of Two Novel Bacteriophages Isolated from a Wastewater Treatment Plant in Qatar
(
American Society for Microbiology
