    • Activated carbon-doped polystyrene fibers for direct contact membrane desalination 

      Esteves, R.J.A.; Gornick, V.; Alqurwani, D.S.; Koenig-Lovejoy, J.; Abdelrazeq, H.; ... more authors ( Springer Nature , 2020 , Article)
      Membranes for direct contact membrane distillation were produced from electrospun polystyrene microfibers doped with activated carbon. The addition of activated carbon reduced the hydrophobicity of the fibers. Therefore, ...

    • Electron-impact ionization of W5+ 

      Jonauskas V.; Kyniene A.; Kučas S.; Pakalka S.; Masys Š.; ... more authors ( American Physical Society , 2019 , Article)
      Electron-impact single-ionization cross sections for the W5+ ion have been studied experimentally and theoretically. Measurements of a detailed ionization spectrum and of absolute cross sections were performed employing ...

    • Energy efficiency of direct contact membrane distillation 

      Ullah R.; Khraisheh M.; Esteves R.J.; McLeskey J.T.; Jr; ... more authors ( Elsevier B.V. , 2018 , Article Review)
      Membrane distillation (MD) is a promising technology due to its ability to function using low temperature differences and low-quality heat sources, thus allowing it to operate on solar or waste heat. The flux and energy ...

    • Energy efficiency of direct contact membrane distillation 

      Ullah R.; Khraisheh M.; Esteves R.J.; McLeskey J.T.; Jr; ... more authors ( Elsevier B.V. , 2018 , Article)
      Membrane distillation (MD) is a promising technology due to its ability to function using low temperature differences and low-quality heat sources, thus allowing it to operate on solar or waste heat. The flux and energy ...

    • Global change effects on plant communities are magnified by time and the number of global change factors imposed 

      Komatsu K.J.; Avolio M.L.; Lemoine N.P.; Isbell F.; Grman E.; ... more authors ( National Academy of Sciences , 2019 , Article)
      Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure ...

    • Molecular Dynamic Simulations of Fibrous Distillation Membranes 

      Hemeda A.A.; Esteves R.J.A.; McLeskey J.T.; Jr; Gad-el-Hak M.; ... more authors ( Elsevier Ltd , 2018 , Article)
      The rate of heat and mass transfer through distillation membranes is typically estimated using an over-simplified, straight-cylindrical-pore approach coupled with several empirical correction factors that are included to ...

    • Performance of electrospun polystyrene membranes in synthetic produced industrial water using direct-contact membrane distillation 

      Abdelrazeq H.; Khraisheh M.; Al Momani F.; McLeskey J.T.; Jr; ... more authors ( Elsevier B.V. , 2020 , Article)
      Desalination of produced water in the gulf petrochemical industry is a continuing challenge to major research groups in the field. With a focus on produced water from desalination plants, it has become crucial to define ...

    • PV power prediction in Qatar based on machine learning approach 

      Benhmed K.; Touati F.; Al-Hitmi M.; Chowdhury N.A.; Gonzales A.S.P.; ... more authors ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)
      PV output power is highly sensitive to many environmental parameters, hence, power available from plants based on this technology will be affected, especially in harsh environments such that of Gulf countries. In order to ...

    • Quantification of pv power and economic losses due to soiling in Qatar 

      Zeedan A.; Barakeh A.; Al-Fakhroo K.; Touati, Farid; Gonzales A.S.P.; ... more authors ( MDPI , 2021 , Article)
      Soiling losses of photovoltaic (PV) panels due to dust lead to a significant decrease in solar energy yield and result in economic losses; this hence poses critical challenges to the viability of PV in smart grid systems. ...

    • Scholarly publishing depends on peer reviewers
