Synthesis and characterization of cobalt hydroxide carbonate nanostructures
( Royal Society of Chemistry , 2017 , Article)Battery-type electrodes of three-dimensional (3D) hierarchical cobalt hydroxide carbonate arrays on Ni foam were fabricated using a hydrothermal method for use in supercapacitors. X-ray diffraction analysis, scanning ... -
Synthesis of Calcium Nitrate Self-Healing Microcapsules Using Aerosol OT Hexane Solution for Cementitious Materials
( Qatar University Press , 2023 , Conference Paper)Calcium nitrate synthesis of in urea-formaldehyde shell has recently been used to produce self-healing microcapsules for construction applications. The original synthesis was based on water-in-oil emulsion with sulfonic ... -
Techno-economic assessment of forward osmosis as a pretreatment process for mitigation of scaling in multi-stage flash seawater desalination process
( Elsevier , 2023 , Article)Thermal desalination processes suffer from the formation of scalants on the heat exchangers of the evaporator unit which negatively affect the process efficiency. This study evaluated the technical and economic feasibility ... -
Temporal variation in walking behavior: An empirical study
( Elsevier Ltd , 2017 , Article)This study provides a baseline for understanding the variation in walking behavior with respect to seasonal conditions in a hot weather country in the Arabian Gulf region. A busy neighborhood with different land-use patterns ... -
Tensile characterization of multi-ply fabric-reinforced cementitious matrix strengthening systems
( Wiley-Blackwell , 2019 , Article)Fabric reinforced cementitious matrix (FRCM) is a composite consisted of high-strength fibers impregnated in a cement-based mortar, and is commonly used for strengthening reinforced concrete and masonry structures. ... -
Textile-Reinforced Mortar (TRM) System as a Strengthening Technique on Reinforced Concrete Beams
