The continuous increase in the demand for plastics is causing severe problems of managing increased waste plastic generation. The hydrocracking of plastic materials is considered an important method of converting these wastes into liquid fuels of high quality. Many attempts have been made in the search for a suitable catalyst [...]

In this study, an electrolyser was used to supply hydrogen to the SI engine. Firstly, the appropriate operation point for the electrolyser was determined by adjusting the amount of KOH in the electrolyte to 5%, 10%, 20% and 30% by mass, and applying 12 V, 16 V, 20 V, 24 [...]

Electricity demand forecasting is an essential process for electricity planning, designing strategies and recommending future energy policies. The changing behavior of the socio-economic growth beside the incomplete coverage of the environmental impacts can make a long-term energy demand forecasting process for a specific energy network challenging. This article presents four [...]

Polycrystalline CuIn0.5Ga0.5Te2 films were deposited by flash evaporation from ingot prepared by reacting, in stoichiometric proportions, high purity Cu, In, Ga and Te elements in vacuum sealed quartz. The as-obtained films were characterized by X – ray diffraction (XRD), transmission electron microscopy (TEM) combined with energy dispersive spectroscopy (EDS). XRD [...]

In this study, the feed-in tariff (FIT) scheme was considered to facilitate an effective introduction of renewable energy in the Kingdom of Bahrain. An economic model was developed for the estimation of feasible FIT rates for photovoltaic (PV) electricity on a residential scale. The calculations of FIT rates were based [...]

In this work, pure and Li-doped Mg2NiH4 hydrides are explored for potential Li-ion battery conversion anode materials applications from state-of-the-art Density functional theory. The most thermodynamically stable Li-doped Mg2NiH4 structure is determined, which possesses a smaller band gap than pure material and owns a theoretical specific capacity of 975.35 mA [...]

An interconnection of a renewable energy source: photovoltaic generator (PVG) with the power grid is investigated. The interconnection uses the conventional power inverter to link the DC PVG with the AC power grid sides. What is new in the interconnection is that an improved control strategy/technique is proposed to control [...]

Abstract: Tungsten oxide (W-oxide) nanoparticles doped and codoped with different transition-metal (TM) ions (Fe, Pt, Cu and Pd) were synthesized by hydrochloric acid-assisted precipitation. The synthesized powders were characterized by X-ray diffraction (XRD), diffuse reflectance spectroscopy (DRS) and magnetic characterization methods. The room temperature (RT) monoclinic (P21/n) structure founded for [...]

Sb2Se3 powder is achieved by mechanical milling of Sb and Se elements. X-ray diffraction analysis indicated the formation of Sb2Se3 orthorhombic phase. The latter finding is confirmed by both X-ray photoelectron spectroscopy characterization and Raman spectroscopy. Magnetic measurement revealed the ferromagnetic character of Sb2Se3 powder. Thin films were obtained by [...]

Replacing the normal electricity and water meters with smart ones is one of the major transformations toward smart cities in the Kingdom of Bahrain. This transformation eliminates the need for manual reading and the estimated monthly billing values. The current approach of the system infrastructure is having the smart meters [...]
