In recent years, extensive researches were devoted to iron oxide nanoparticles (IONPs), including magnetite (Fe3O4) and maghemite (γ-Fe2O3), due to their low toxicity and cost, in addition to their unique physicochemical and magnetic properties. In this review, we present a brief introduction on IONPs in terms of classification and properties. [...]

Fabrication of a suitable photocatalyst which can efficiently propagate catalytic properties in visible spectrum has always been a challenge. Novel nanocomposites LaDySn 2 O 7 /SnSe as well as the individual components of the composite were fabricated via the hydrothermal route. The structural, textural as well as optical characteristics of [...]

ANN is a very well-known approach used for classification based on supervised machine learning. This approach faces some issues, notably the local minima problem, which leads to diminished accuracy in the results. To solve the problem of local minima, a new algorithm called RPSOGAC has been proposed. The proposed algorithm [...]

Pure and Ni-doped WO 3 nanoparticles were synthesized by hydraulic acid-assisted precipitation, followed by thermal calcinations. The procedure utilized sodium tungstate (Na 2 WO 4 ) doped with different amounts of Ni ions. The samples were characterized by X-ray diffraction (XRD), diffuse reflectance spectroscopy (DRS), and magnetic measurements. The XRD [...]

The aim of this work is to reduce the impact on the environment of a basic textile dye (azucryl red) using a semiconductor TiO2 and Fe doped TiO2 powders calcined at 600 °C as catalysts. The refinements based on the Rietveld method of x-ray diffraction patterns indicate the formation of [...]

Nitro aromatic compounds such as, 2-nitrophenol and 4-nitrophenol are identified lethal to human due to their constructive role in causing the problems such as, vertigo, headache, fainting and mental disturbance. A strong remedy is desired to treat aqueous environment for these toxic aromatic species. In this pursuance, gum arabic (GA) [...]

In 2011, Bahrain Petroleum Company inaugurated the country’s first Hybrid Renewable Energy System (HRES) as a demonstration project, which partially supplies the electricity required for the reception hall of the company’s park. Data collected from the system for a full year were analyzed to assess the performance of this grid-connected [...]

Tin sulfide (SnS)has attracted a great interest recently due to its high absorption coefficient (∼104 cm−1), facile deposition and low-cost. This research work consists on a comprehensive photoresponse investigation of flexible π-SnS photodetector analyzed under illumination of near-infrared (NIR). The π-SnS film has been deposited onto a flexible substrate polyethylene [...]

Generation system reliability is an important factor in the long-term planning for future capacity expansion to make sure that the total installed capacity is enough to support demand. This case is very important for smart cities, because it is focusing on the optimal solution. Whenever the number of days very [...]

Citizen records are scattered between different state organizations. It wastes time, effort, and resources for both citizen and organization to collect, maintain, and update records to fulfill citizen services. Interoperability is a key element that enables seamless collaboration between different entities. It requires non-conventional methods to overcome interoperability challenges such [...]
