Special Issue Information

Dear Colleagues,

The majority of chemically formulated products involve nanotechnology. Ice creams, sun screen lotions, toothpastes, lipsticks, paints, glues, and bituminous binders are some examples. These chemical products include polyphasic systems, in which several phases (liquid, solid and gas) have to coexist, leading to various interfaces. To reach the specific end-use properties required for these systems, a subtle combination of scientific disciplines comes into play. These include formulation science (colloid chemistry, dispersed systems, surfactants and nanoparticles), chemical engineering (mixing and emulsification processes), rheology (flowing and hydrodynamic and structural characteristic properties), and interfaces (interfacial rheology, particle adsorption, surface tension and wetting). In addition, the behavior of the nanoparticles or nanoobjects at the various interfaces has become a hot topic in this field. Recently, interfacial rheology has emerged as a new method to study the hydrodynamic and structural characteristic properties of interfaces.

Therefore, the main focus of this Special Issue is to cover the recent advances in nanotechnology for chemically formulated products and, more particularly, for interfacial rheology, dispersed systems, and colloid chemistry. The main aspect of this research area may include, but is not exclusive to, the following topics:

  • Particle-laden interfaces;
  • Pickering emulsions and foams;
  • Relation between interfacial and bulk properties;
  • Repartition of the particles in liquid/liquid and liquid/gas systems;
  • Asphaltenes and enhanced oil recovery of crude oils;
  • Advantages of nanoparticles for soft matter.

Polymer flooding is one of the enhanced oil recovery (EOR) methods that increase the macroscopic efficiency of the flooding process and enhanced crude oil recovery. In this study, the effect of silica nanoparticles (NP-SiO2) in xanthan gum (XG) solutions was investigated through the analysis of efficiency in core flooding tests. First, the viscosity profiles of two polymer solutions, XG biopolymer and synthetic hydrolyzed polyacrylamide (HPAM) polymer, were characterized individually through rheological measurements, with and without salt (NaCl). Both polymer solutions were found suitable for oil recovery at limited temperatures and salinities. Then, nanofluids composed of XG and dispersed NP-SiO2 were studied through rheological tests. The addition of nanoparticles was shown to produce a slight effect on the viscosity of the fluids, which was more remarkable over time. Interfacial tension tests were measured in water-mineral oil systems, without finding an effect on the interfacial properties with the addition of polymer or nanoparticles in the aqueous phase. Finally, three core flooding experiments were conducted using sandstone core plugs and mineral oil. The polymers solutions (XG and HPAM) with 3% NaCl recovered 6.6% and 7.5% of the residual oil from the core, respectively. In contrast, the nanofluid formulation recovered about 13% of the residual oil, which was almost double that of the original XG solution. The nanofluid was therefore more effective at boosting oil recovery in the sandstone core. Full article
