Underwater friction stir welding of Al-Mg alloy: Thermo-mechanical modeling and validation
Published 2021“…To better understand the effects of the water environment, the results were compared with conventional friction stir welding (FSW) conditions. Thermal profile and surface heat flux results revealed that lower preheated area (PHA) at the leading edge (LE) decreased the total amount of frictional heat generation in the UFSWed joint. …”

INVESTIGATION OF SPATIOTEMPORAL VARIABILITY AND CONTAMINATION OF PLASTIC MARINE DEBRIS IN QATAR’S COASTAL WATERS
Published 2015“…Microplastics are tiny plastic particles that seldom originate from fragmentation of large plastic debris or are produced to serve some specific purposes. Microplastics pose greater threats as they can be mistaken for food by filter-feeders and planktivorous fish, and can also adsorb large quantities of recalcitrant organic pollutants (OPs) which biomagnify up the marine food web, hence, explains the need for their investigation. …”
