Development of novel thin film composite reverse osmosis membranes for desalination
( American Institute of Physics Inc. , 2019 , Conference Paper)Microporous Polyetherimide (PEI) membranes were prepared by wet phase inversion at different temperatures. The thin film composites (TFC) of polyamide on microporous PEI were prepared using meta-Phenylenediamine (MPD) and ... -
Influence of TMAl preflow on AlN epitaxy on sapphire
( American Institute of Physics Inc. , 2017 , Article)The trimethylaluminum (TMAl) preflow process has been widely applied on sapphire substrates prior to growing Al-polar AlN films by metalorganic chemical vapor deposition. However, it has been unclear how the TMAl preflow ... -
Instability of Langmuir-beam waves: Kappa-distributed electrons
( American Institute of Physics Inc. , 2023 , Article)In space plasmas, electron populations exhibit non-equilibrium velocity distributions with high-energy tails that are reproduced by the Kappa power-laws and contrast with the Maxwellian distributions often used in theoretical ... -
Laundry wastewater treatment using ultrafiltration under different operating conditions
( American Institute of Physics Inc. , 2018 , Conference Paper)The laundry wastewater of one of the hospitals in Qatar was selected and studied. It was found that hospital laundry is releasing considerable amount of wastewater i.e. 1800 - 2500 liters/cycle while washing 40 - 50 kg of ...
