Functionalization of silica-coated magnetic nanoparticles as powerful demulsifier to recover oil from oil-in-water emulsion حسب Elmobarak W.F.

"…The Fe–Si-MNP were prepared with differing silica layer thicknesses (5 nm [Fe–Si-1], 8 nm [Fe–Si-2], 10 nm [Fe–Si-3], and 15 nm [Fe–Si-4]) and tested for the percentage of oil separation (%Soil) under different dosages (DMNP), oil concentration (Doil), surfactant dosages (Dsur), and pH. …"

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

"…The sensing mechanism of the graphene-based sensors can be summarized as follows: exposure of the graphene sensor to Hg2+ ions decreases electron concentration in the n-type graphene, thus, the conductance of the sensor decreases. …"
