Microemulsions, as thermodynamically stable mixtures of oil, water, and surfactant, are
known and have been studied for more than 70 years. However, even today there are still …

Supercritical carbon dioxide (scCO2) is a unique solvent with a wide range of interesting
properties. This review focuses upon recent advances in the use of scCO2 in materials …

The concept of hydrophilic/CO2-philic balance (HCB) was extended to describe stabilization
of carbon dioxide-in-water (C/W) foams (also called emulsions) with silica nanoparticles …

Synergistic interactions at the interface of nanoparticles (bare colloidal silica) and surfactant
(caprylamidopropyl betaine) led to the generation of viscous and stable CO2‐in‐water (C/W) …

Recent improvements in beam-line accessibility and technology have led to small-angle
neutron scattering (SANS) becoming more frequently applied to materials problems. SANS …

The morphologies, stabilities, and viscosities of high-pressure carbon dioxide-in-water (C/W)
foams (emulsions) formed with branched nonionic hydrocarbon surfactants were …

Nonionic methylated branched hydrocarbon surfactants, poly (ethylene glycol) 2, 6, 8-
trimethyl-4-nonyl ethers, form water-in-carbon dioxide (W/C) microemulsions. A …

The interfacial tensions, surface pressures, and adsorption of nonionic hydrocarbon
surfactants at the air–water (A–W) and carbon dioxide–water (C–W) interfaces were …

In this work, we have prepared CO2-in-water foam by mixing partially hydrophobic SiO2
nanoparticles and sodium bis (2-ethylhexyl) sulfosuccinate (AOT) and studied its properties …

CO2 foam injection has been shown to be effective under reservoir conditions for enhanced
oil recovery. However, its application requires a certain stability and surfactant absorbability …
