The implementation of nano-sized TiO2 dispersions for mass coloration of polyimide fibers is considered in the paper. Titanium dioxide (TiO2) is not classified as hazardous according to United Nations (UN) Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The...

The objective of this research is to develop cost-effective surfactant flooding technology by using simulation studies to evaluate and optimize alternative design strategies taking into account reservoir characteristics process chemistry, and process design options such as horizontal wells. Task...

CO2 hydrate slurry can be used in a lot of practical applications such as CO2 capture, CO2 storage-transportation and CO2 sequestration processes. However, CO2 hydrate slurry is generally formed at low temperature and high pressure. The objectives of this study are to develop new absorbents to...

In this work, we consider bilayer biomembranes or surfactants made of two amphiphiles A and B. Under a variation of a suitable parameter, such as temperature or difference of lengths of hydrophobic chains, these systems undergo a phase separation from a homogeneous liquid-phase to two distinct...

Imidazoline surfactants belong to the category of cationic surfactants. Cationic surfactants are often quaternary nitrogen salts and are widely used both in nonaqueous systems and in applications such as textile softeners, dispersants, and emulsifiers. This study describes the surface-active...

We investigate the effect of shear flow on a lamellar-sponge phase-separating fluid when subjected to shear flow. We show the existence of two different steady states (droplets and ribbons structures) whose nature does not depend on the way to reach the two-phase unstable region of the phase...

In this paper a constitutive equation is derived for surface diffusion in multicomponent surfaces that exhibit linear viscoelastic behavior with fading memory. The equation is based on the Maxwell–Stefan theory for diffusion. The constitutive equation incorporates the effects of ordinary...
