The rapid economic and population growth of Qatar during the last few decades led to generation of substantial volume of municipal treated sewage effluent (TSE). Most of this water was disposed into Abu Nakhla depression at the outskirt of Doha city since 1985. Abu Nakhla depression is situated at the south-west of Doha. The mixture of these effluents with surface and ground waters during rainy seasons created a consp Read More

Plasmonics is an emerging broad area of research, which studies the exceptional optical properties of metallic 2D and 3D nano-structures, i.e. confinement of electromagnetic waves (surface plasmon polaritons) [1]. During the past years, there has been a huge interest in employing plasmonic structures for sunlight harvesting [2], i.e. for example in thermal photovoltaics, thin-film solar cells, or solar thermoelectrics, Read More

Performance and reliability is essential factor for deploying the solar Photovoltaic (PV) technology in desert environment due to the high ambient temperature and high humidity. During daytime, the PV conversion efficiency decreases considerably due to high temperature and weak natural cooling effects on PV modules. During night, sky radiation cooling promotes atmospheric water vapor condensation on PV modules surfa Read More

In multi layered reservoirs the fluid composition may differ from one layer to another. The knowledge of the lateral and vertical fluid heterogeneities may help to better understand the fluid distribution in the field and consequently contribute to enlighten production. Several mechanisms can affect the fluid composition, like origin, maturity, alteration or physical conditions. The objective of this study is to prese Read More

Silicon heterojunction (SHJ) solar modules are an attractive and suitable option for application in high temperature environment such as in the state of Qatar. This is mainly related to their high open-circuit voltage (Voc) [1], which is essential for achieving better performance at high temperatures. High efficiency SHJ solar cells are usually made from high-quality n-type monocrystalline silicon wafers, which increases t Read More

Degradation of materails due to corrosion has now emerged as an international challenge which is compelling the community to trace out some smart solutions on priority basis. Corrosion mitigation is not only important as it results in wastage of our natural resources, time, money and efforts, but more importantly its inadequate handling may lead to the safety threats. Some, such sad incidents have been reported in th Read More

The demand for cooling in Gulf region is the direct effect of its high atmospheric temperature. Around 60% of the electricity demand in GCC is for cooling purpose. The main source of cooling and air-conditioning in these countries are conventional electric compression cycle, which leads to the increase in the GHG emission, directly in the form of leaked gases from these systems and indirectly in the form of fossil fuel used for th Read More

This work reports on sensitive and selective gas sensors based on copper ferrite (CuFe2O4) nanoparticles. The nanoparticles were produced different methods including: colloid microwave assisted hydrothermal method, and co-precipitation method. Those methods enable a precise control of nanoparticle size, The produced nanoparticles were annealed at different temperatures. Structural analysis were carried out Read More

Physical Oceanography is the study of the conditions and processes that govern the movement of ocean water, and its interaction with coastal, seafloor, and atmospheric boundaries. Understanding these processes helps to provide deeper insight into various ecological and physical phenomena that affect the earth's near-surface systems. Furthermore, consideration of physical oceanography is critical for sustainable Read More
