CARBON BASED CONDUCTIVE FIBERS FOR FUEL CELL APPLICATION
(2018 , Master Thesis)A novel catalyst consists of a group of metals (Ni, Co and Cu) deposited on carbon fiber support and was prepared for oxidation using methanol and ethanol in alkaline medium. The carbon fiber support was fabricated by ... -
ISOLATION, IDENTIFICATION, DIFFERENTIATION AND SCREENING OF LOCAL AEROBIC UREOLYTIC BACTERIA INVOLVED IN MICROBIALLY INDUCED CALCIUM CARBONATE PRECIPITATION IN QATARI SOIL.
(2018 , Master Thesis)Biomineralization plays an important role in stabilizing the soil by modifying its geological and physical properties, hence, acting as a stabilizer against wind erosion specially in regions characterized by harsh soil ... -
Multiscale structural evolution of citrate-triggered intrafibrillar and interfibrillar mineralization in dense collagen gels
( Academic Press Inc. , 2020 , Article)The mineralized extracellular matrix of bone is an organic?inorganic nanocomposite consisting primarily of carbonated hydroxyapatite, fibrous type I collagen, noncollagenous proteins, proteoglycans, and diverse biomolecules ... -
NEW SULFUR-DOPED CARBON FIBER – SUPPORTED ALLOYS FOR ELECTROCATALYTIC REDUCTION OF OXYGEN FOR PEM FUEL CELLS APPLICATIONS
(2018 , Master Thesis)The daily increase in the world needs for new sources of energy, the population and economy growth, and the industrial expansions made the demand for new sources of energy a critical request within different societies. ... -
Preparation and characterization of green graphene using grape seed extract for bioapplications
( Elsevier Ltd , 2016 , Article)The development of functionalized graphene materials concerning health and environmental aspects via green approaches is currently the most recent topic in the field of nanoscience and nanotechnology. Herein, we report the ... -
Synthesis and performance evaluation of Na(2-x)LixFeP2O7 (x=0, 0.6) hybrid cathodes
( John Wiley and Sons Inc , 2020 , Article)This study reports hybrid cathodes formation by cation substitution in which Li+ substitution has been considered for Na+ in the structure of Na(2-x)LixFeP2O7 (x=0, 0.6) to form Na1.4Li0.6FeP2O7 cathodes. Na(2-x)LixFeP2O7 ... -
Thermoelectric Behavior of Nanocrystalline Tin Selenide Nanocomposites
(2018 , Master Thesis)Thermoelectric technology converts thermal energy to electricity. Many studies were conducted on thermoelectric materials such as Bismuth Telluride and Lead Telluride. And the goal was to achieve an average ZT >2 which is ...
