Dosage Optimization of Polypropylene Fiber for Strength Enhancement of Cementitious Composites
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"Concrete is the most commonly used materials for construction in Qatar as well as in
the world. Exposure to sever environmental conditions causes physical deterioration
of concrete structures and significantly affect ...
Design of hybrid clay/ polypyrrole decorated with silver and zinc oxide nanoparticles for anticorrosive and antibacterial applications
(
Elsevier
, 2020 , Article)
In this work, a novel and cost-effective bentonite intercalated with polypyrrole Zinc oxide-silver nanocomposite (B-PPy/ZnO) hybrid material was prepared via in situ photopolymerization of pyrrole in the presence of silanized ...
High and Ultra-high Performance Concretes: A Solution to Reinforced Concrete Durability under Harsh Climate of Arabian Gulf
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Reinforced concrete (RC) infrastructure in the Arabian Gulf region deteriorates under
severe environmental conditions after only short service life. To overcome this problem,
it is imperative to employ high-quality concretes ...
Effect of Alkaline Activators on the Mechanical Properties of Geopolymer Mortar
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"Geopolymerization is a process where silica and alumina rich source materials turn
into excellent binding materials by the aid of alkali solutions. Materials such as fly ash
are by-products in energy power plants. Fly ...
Recent developments in the application of nanomaterials in agroecosystems
(
MDPI AG
, 2020 , Article)
Nanotechnology implies the scientific research, development, and manufacture, along with processing, of materials and structures on a nano scale. Presently, the contamination of metalloids and metals in the soil has gained ...
Sustainable use of nanomaterials in textiles and their environmental impact
(
MDPI AG
, 2020 , Article)
At present, nanotechnology is a priority in research in several nations due to its massive capability and financial impact. However, due to the uncertainties and abnormalities in shape, size, and chemical compositions, the ...
Separation of water/oil emulsions by an electrospun copolyamide mat covered with a 2D Ti3C2Tx MXene
(
MDPI AG
, 2020 , Article)
Purpose: Copolyamide 6,10 (coPA) electrospun mats were covered with multilayered (ML) and single-layered (SL) MXene (Ti3C2Tx) as a membrane for the separation of water/vegetable oil emulsions. Methods: Prepared membranes ...
Improved electrochemical performance of SiO2-coated Li-rich layered oxides-Li1.2Ni0.13Mn0.54Co0.13O2
(
Springer
, 2020 , Article)
Lithium-rich layered oxides (LLOs) such as Li1.2Ni0.13Mn0.54Co0.13O2 are suitable cathode materials for future lithium-ion batteries (LIBs). Despite some salient advantages, like low cost, ease of fabrication, high capacity, ...
Long-Term Stability Analysis of 3D and 2D/3D Hybrid Perovskite Solar Cells Using Electrochemical Impedance Spectroscopy
(
MDPI
, 2020 , Article)
Despite the remarkable progress in perovskite solar cells (PSCs), their instability and rapid degradation over time still restrict their commercialization. A 2D capping layer has been proved to overcome the stability issues; ...
Enhanced corrosion protection of Epoxy/ZnO-NiO nanocomposite coatings on steel
(
MDPI AG
, 2020 , Article)
ZnO-NiO nanocomposite with epoxy coating on mild steel has been fabricated by the sol–gel assisted method. The synthesized sample was used to study corrosion protection. The analysis was performed by electrochemical impedance ...
