Alumina is one of the most widely used ceramic materials as catalysts, catalyst supports and absorbents, and also wear resistant coating. This study focused on fabricating and characterizing of alumina ceramic nanoparticles fabricated using new and simple sol-gel method. Aluminium oxide (Al2O3) nanoparticles were synthesized by iron (III) nitrate 9-hydrate as precursor. Physicochemical properti...
Background and Objectives: The contamination of nitrate (NO3−) in groundwater resources causes two adverse health effects: induction of “blue-baby syndrome” (methemoglobinemia), especially in infants, and the potential formation of carcinogenic nitrosamines. The aim of this research is to investigate nitrate removal from groundwater using alumina nanoparticles and to determine the adsorption is...
Abstract Nanotechnology is widely used in construction to advance high performance and durability materials, as represented by concrete, which nanomaterials such nanosilica (SiO 2 ), nano-alumina (Al O 3 nanotitanium oxide (TiO ) are replace cement a partial binder. Suitable amounts of adding these beneficial with regard the mechanical, economic, environmental aspects concrete.
Abstract: composition of MgO and nano boehmite. The reactant and potassium chloride, as the reaction media, were fired at800-1000 °C at different dwell times (0.5-5 h) in the ambient atmosphere. After washing and filtration, the spinel nanopowder was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) techniques. It was demonstrated tha...
