Research Interests
My research work is focused to understand adsorption, self-assembly and desorption of amphiphilic molecules (fatty acids, fatty amines, aromatic surfactants) on solid substrates, in the context of getting a better understanding of enhance oil recovery processes. The microscopic forces governing the interaction of various components of crude oils (e.g. asphaltenes, fines) with the rock depend on the local chemistry and charge of the surface. The latter is known to vary upon exposure to electrolytes of variable composition (ionic strength, valency, chemical nature of ions, pH). I use high resolution AFM imaging and spectroscopy techniques to characterize the surface properties of model clay/rock surfaces exposed to salt solutions of variable composition.
