An investigation of the Performance of a Conical Solar Water Heater in the Kingdom of Bahrain

Authors: Gaaliche N., Ayhan T., Fathallah R.
Domestic water heater corresponds to 25% of the house energy consumption and can play an important role to reduce energy house expenses. Solar energy offers a preferred renewable energy resource because of its economic and environmental advantages. It is considered the best alternative to reduce domestic water heater energy consumption [...]

Energy Consumption Trends in Energy Scarce and Rich Countries: Comparative Study for Pakistan and Saudi Arabia

Authors: Gazder U.
Energy crisis is raising serious concerns throughout the world. There has been constant rise in energy consumption corresponding to the increase in global population. This sector affects the other pillars of national economy including industries and transportation. Because of these reasons, the traditional fossil-based energy sources are depleting rapidly, resulting [...]

Smart PV grid to reinforce the electrical network

Authors: Al-Hamad M.Y., Qamber I.S.
Photovoltaic (PV) became the new competitive energy resources of the planet and needs to be engaged in grid to break up the congestion in both Distribution and Transmission systems. The objective of this research is to reduce the load flow through the distribution and transmission equipment by 20%. This reduction [...]

A Geospatial Database for Wind and Solar Energy Applications: The Kingdom of Bahrain Study Case

Authors: Al-Joburi K., Dahman N.
This research is aimed at designing, implementing, and testing a geospatial database for wind and solar energy applications in the Kingdom of Bahrain. All decision making needed to determine economic feasibility and establish site location for wind turbines or solar panels depends primarily on geospatial feature theme information and non-spatial [...]

Fabrication of covalently bonded nanostructured thin films of epoxy resin and polydimethylsiloxane for oil adsorption

Authors: Batool S., Mahmood A., Gill R., Qureshi S.S., Mazhar M., Bououdina M.
Thin films of architectures PEI(CNERa/PDMS)n, PEI(CNERb/PDMS)n, (PEI/CNERb)n and PEI(CNERb/NH2-MMT/PEI)n have been fabricated via covalent layer-by-layer technique. Different film deposition parameters such as solvent type, polymer concentration, polymer ratio and dipping time have been optimized to achieve a uniform growth of layers. The effect of polymer concentration and dipping time on [...]

Structural, Optical, and Magnetic Properties of Zn-Doped CoFe2O4 Nanoparticles

Authors: Tatarchuk T., Bououdina M., Macyk W., Shyichuk O., Paliychuk N., Yaremiy I., Al-Najar B., Pacia M.
The effect of Zn-doping in CoFe2O4 nanoparticles (NPs) through chemical co-precipitation route was investigated in term of structural, optical, and magnetic properties. Both XRD and FTIR analyses confirm the formation of cubic spinel phase, where the crystallite size changes with Zn content from 46 to 77 nm. The Scherrer method, Williamson-Hall [...]

Purchase behaviour of Indian customers towards environment friendly motor vehicles

Authors: Upadhyaya M.
At the present time lot of customers in India are buying environment friendly motor vehicles like hybrid and electric vehicles. Therefore, this study was performed to recognize the factors that influence the purchase intention of buying environment friendly motor vehicles among Indian customers. Information is collected from 125 vehicle owners [...]

Structural characterization and optical constants of CuIn3Se5 vacuum and air annealed thin films

Authors: Segmane N.E.H., Abdelkader D., Amara A., Drici A., Akkari F.C., Khemiri N., Bououdina M., Kanzari M., Bernède J.C.
Milled powder of ordered defect compound (ODC) CuIn3Se5 phase was successfully synthesized via milling process. Thin films of CuIn3Se5 were deposited onto glass substrates at room temperature by thermal evaporation technique. The obtained layers were annealed in vacuum and air atmosphere. The structural and compositional properties of the powder were [...]

Facile hydrogenation of N-heteroarenes by magnetic nanoparticle-supported sub-nanometric Rh catalysts in aqueous medium

Authors: Nasiruzzaman Shaikh M., Aziz M.A., Kalanthoden A.N., Helal A., Hakeem A.S., Bououdina M.
The hydrogenation of nitrogen-containing heterocyclic precursors in aqueous medium at low temperature without imposing molecular hydrogen pressure is quite challenging. Herein, we report the synthesis and performance of a novel catalyst capable of facile hydrogenation (employing tetrahydroxydiboron (THDB) as the reductant) of N-heteroarenes in water at 80 °C with good [...]
