Application of Fe3O4 magnetite nanoparticles grafted in silica (SiO2) for oil recovery from oil in water emulsions
Published 2021“…Using an MDdose as low as 10 mg/L attained a %ηdem in the range of 93%–94.3% for O/W mixtures with Coil < 2000 mg/L, which slightly decreased to ∼90% for higher concentrations. The reported %Roil (p-value <0.05) was >90 ± 0.1 for tests carried out with pH ≤ 7 and Csur ≤ 0.1 g/L and declined at higher pH and Csur to % 86.5 due to the increase in emulsion stability. …”

Estimation of Mechanical Properties of Copper Powder Filled Linear Low-Density Polyethylene Composites
Published 2022“…The input parameters manipulated for the prediction were elongation at break (δ), stress at break (ρ), Young’s modulus (Y), volume fraction of the filler (ϕ) and constants (KE1,KE2,KS1,KS2,KS3,KS4,KY1). Copper powder filled LLDPE has a complex structure which makes it difficult to accurately predict the mechanical properties. …”

Novel electroless deposited corrosion — resistant and anti-bacterial NiP–TiNi nanocomposite coatings
Published 2019“…The addition of TiNi nanoparticles into the NiP matrix leads to the transformation of the amorphous structure of the as-plated NiP into a semi-crystalline one. The microhardness of the composite coating significantly enhances with increasing the TiNi concentration up to 0.4 g L−1 and further improvement takes place after the heat treatment. …”

Experimental study of exhaust emissions and performance of a dual fuel IDI diesel engine
Published 1999“…Methane and, sometime, propane were used as the gaseous fuel while regular diesel fuel was used as the pilot one. The admission of more gaseous fuel with the intake air increased the engine power, thermal efficiency, and NOx emissions while CO and UHC emissions increased up to the flame initiation limit beyond which they decreased sharply. …”
