An acetylene black electrode modified by an adsorbed cationic surfactant, cetyltrimethylammonium bromide (CTAB), was developed. The influences of various types of surfactants on the electroreduction of O2 were investigated. It was demonstrated that a cationic surfactant, CTAB, on the surface of the electrode could significantly decrease the overpotential of dioxygen reduction, and the reduction...

Surfactant exfoliated 2D hexagonal Boron Nitride (2D-hBN) nanosheets are explored as a potential electrochemical sensing platform and evaluated towards the electroanalytical sensing of dopamine (DA) in the presence of the common interferents, ascorbic acid (AA) and uric acid (UA). Surfactant exfoliated 2D-hBN nanosheets (2-4 layers) fabricated using sodium cholate in aqueous media are electrica...

This paper presents the adsorption of crystal violet (CV+) from aqueous solution on surfactant-modified dolomite. Liquid phase batch operations were carried out to observe the effect of various experimental parameters such as initial dye concentration, adsorbent dosage, pH and NaCl concentration. The optimum conditions for these parameters were calculated by Taguchi method. Equilibrium isotherm...

drilling fluid is the most important lifeline of the drilling operation, that main task is facilitate the cuttings removal of the drilling. there are varieties of drilling fluids such as sodium bentonite based-drilling fluid is called “mud” and drilling foam or surfactant based-drilling fluid is called “soap”. the present work aims are study on the modified drilling mud properties by using the ...

We use a pore-scale network model in conjunction with conventional reservoir-scale simulations to investigate wettability variation within an oil/water transition zone. If the initial water saturation within the transition zone is controlled by primary drainage, we predict that initial production behavior is the same regardless of wettability. However, if the initial water saturation has been m...

Abstract Microemulsion (ME) is widely used in food, pharmaceuticals, and medical applications. In the formulation of MEs, a substantial amount surfactant needed to stabilize lipo-hydrophilic interface, which may have adverse effects on biological cells. Cellulose its derivatives been extensively utilized as solid emulsifying agents, known pickering are added improve stability emulsions. this st...
