... and characterization in order to reveal criticalities associated to the application of this technology. A possible key role of the coexistence, in nanoemulsions, of small droplets size, surfactants mixture and solvent has been highlighted. In fact, these factors can favourably impact, in a synergic way, some critical...

... as presented at OMC 2017 has not been reviewed by the Programme Committee. ABSTRACT The aim of this research is to Preparation of nonionic surfactants from Oleic acid and their application in the field of corrosion inhibitors are the main goal of the present work. In this respect, oleic acid reacted...

... ABSTRACT Some quaternary ammonium Gemini surfactants were prepared, characterized, and evaluated as corrosion inhibitors for carbon steel in oil wells formation water containing sulfide ions. The effect of molecular structure on the inhibition efficiency was investigated by quantum chemical...

... nanometric solvent droplets are dispersed in water using proper surfactant mixtures. Nanoemulsions can be formed with different techniques including high energy or low energy methods and, if properly formulated, can show very high kinetic stability as a direct consequence of monodispersity that minimize...
