Properties and thermal stabilization of Nanocrystalline copper via solute additions of niobium
(Material Science and Technology, 2017 , Master Thesis)
Nanocrystalline materials, those with grain size <100 nm, were found to have superior mechanical properties compared to their coarse-grained (CG) counterparts. However, these materials are not thermally stable because of ...
NITROGEN AND SULFUR– DOPED CARBON NANOFIBER MIXED OXIDES COMPOSITES FOR SUPERCAPACITOR APPLICATIONS
(Materials Science and Technology, 2016 , Master Thesis)
Energy storage devices including supercapacitor are among the rapidly growing field of alternatives for rechargeable batteries due to its high energy density and long life cyclability performance. Electrospinning is a ...
Er Doped III-Nitride Semiconductors
(Material Science and Technology, 2017 , Master Thesis)
Erbium ions (Er3+) doped in a solid material enables the intra 4f shell transitions from its first excited state (4I13/2) to the ground state (4I15/2). The intra-4f shell transition at 1540 nm is of exceptional interest ...
Biodegradable thermoplastic polyurethane composites as potential plating systems in pediatric facial fractures
(Material Science and Technology, 2022 , Master Thesis)
Due to the rapid growth of facial bone in the pediatric age group, the use of metallic plates would require a second surgical intervention to remove it. The alternative is biodegradable plating systems which are safe but ...

(Material Science and Technology, 2020 , Master Thesis)
Carbon-based (CNs) nanostructures attracted great attention in various conversion energy technologies, owing to their unique"physicochemical properties such as high surface area, abundant active sites, and stability. Herein, ...
Designing of polyethylene-based material modified by plasma discharge for water/oil separation
(Material Science and Technology, 2021 , Master Thesis)
Produced water (PW) from petrochemical industries is one of the largest
wastewaters generated in Qatar. Soluble and insoluble oil contaminants occur in this
water and must be removed if water will be used or discharged ...
