INVESTIGATION OF SPATIOTEMPORAL VARIABILITY AND CONTAMINATION OF PLASTIC MARINE DEBRIS IN QATAR’S COASTAL WATERS حسب Abayomi, Oyebamiji Abib

"…The pellets were analyzed for PCBs and PAHs and undeployed pellets were also analyzed at time 0. Adsorbed PCBs and PAHs concentration showed a steady decrease with time, suggesting that contaminated pellets ending in the marine environment release their adsorbed contaminants in less contaminated seawaters revealing a complex OPs dynamic between plastics an seawater as a function of differential concentrations of pollutants. …"

Fabrication of Selective Sensors for Hg2+ Traces in Water Using Graphene Decorated with Metal Nanoclusters حسب Ayesh, Ahmad I.

"…Each Hg2+ sensor was fabricated using (1 cm × 1 cm) commercial graphene layer on SiO2/doped-Si substrate (thickness of SiO2 is 285 nm, and Si is p-type with resistivity of 0.001-0.005 ohm.cm). Interdigitated parallel Au electrodes (with electrode separation of 100 μm) were fabricated by thermal evaporation using a Torr International evaporator through a shadow mask on the surface of graphene [6]. …"
