TiO2 nanotubes and mesoporous silica as containers in self-healing epoxy coatings
( Nature Publishing Group , 2016 , Article)The potential of inorganic nanomaterials as reservoirs for healing agents is presented here. Mesoporous silica (SBA-15) and TiO2 nanotubes (TNTs) were synthesized. Both epoxy-encapsulated TiO2 nanotubes and amine-immobilized ... -
TiO2 nanotubes with ultrathin walls for enhanced water splitting
( Royal Society of Chemistry , 2015 , Article)We demonstrate, for the first time, the synthesis of titania nanotubes with ultrathin (3–5 nm) wall thickness. As revealed by the incident photon-to-current collection efficiency (IPCE) and electrochemical impedance ... -
TiO2-functionalized biochar from pistachio nutshells: adsorptive removal and photocatalytic decolorization of methyl orange
(2023 , Article)Pistachio nutshells-derived biochar (PNS-BC) was utilized as a cost-effective adsorbent for competently removing a model dye, methyl orange (MO) from wastewater. Three concentrations of TiO2; 1%, 2%, and 3% were used to ... -
TiO2-pillared clays with well-ordered porous structure and excellent photocatalytic activity
( Royal Society of Chemistry , 2015 , Article)TiO2-pillared clays with well-ordered porous structures are successfully prepared via incorporating TiO2 nanosol particles into the clays, where empty octahedral sites are partially modified with divalent metal ions such ... -

The framing of the World Cup 2022 in the press of the UAE is especially ... -
Toads in Qatar: The species present and their probable original source
( Elsevier , 2019 , Article)Toads are likely to have been introduced to Qatar, but little information is available on toad populations in the country, including the species present and their probable origin. Therefore, we collected tissue samples for ... -
Tobacco Use and Its Health Effects among Professional Athletes in Qatar
( Hindawi Limited , 2016 , Article)The objective of the study was to determine the effects of tobacco use on selected markers of health and lung function in professional athletes. A total of 108 male professional athletes participated in the study from ten ... -
Total asymptotically nonexpansive mappings in uniformly convex metric spaces
( Politechnica University of Bucharest , 2019 , Article)We approximate common fixed point of a pair of total asymptotically nonexpansive mappings in the setting of a uniformly convex metric space. The proposed algorithm is computationally simpler than the existing ones in the ... -
