Investigation of Asphaltene Adsorption at Liquid-Liquid and Liquid-Solid Interfaces
<p>Asphaltenes, as indigenous components in crude oils, are believed to play an important role in the petroleum production and processing industry. For example, asphaltene molecules can adsorb onto the water / oil interface like the amphiphiles and hinder water droplet coalescence, resulting in the …

Nuclear magnetic resonance and dynamic polarization studies of liquid/liquid and liquid/solid interfaces
In the present study, interactions at the liquid/liquid and liquid/solid interfaces have been investigated by the combination of both nuclear magnetic resonance (NMR) and dynamic nuclear polarization (DNP) techniques. The ¹³C and ¹⁵N paramagnetic contact shifts, and ¹H, ¹³C, and ¹⁵N relaxation …

Quantitative analysis of protein liquid-liquid phase separation
… proteins tend to demix into a protein-rich liquid condensate phase and a protein-poor dilution phase. This process of liquid–liquid phase separation (LLPS) has emerged as a crucial mechanism for describing the production of biological condensates in live cells, which have been found to be …

Liquid-on-liquid mixing for slide-based biological assays
… of results, can take days to achieve. The liquid-on-liquid mixing (LOLM) method overcomes the diffusion barrier by layering an immiscible spectator fluid, such as mineral oil, on the thin film. Stirring the spectator fluid transmits shear at the liquid-liquid interface into the thin film. …

The Modification of Solvents for Liquid-Liquid Extraction Processes
… to modify the efficiency of selected solvents in liquid-liquid extraction by the addition of small amounts of additives would offer advantages in extraction, solvent recovery and inventory costs. Therefore, the literature relating to desirable solvent properties, variations in solvent use, methods …

Modeling Flow-Induced Microstructure of Inhomogeneous Liquid-Liquid Mixtures
Liquid-liquid dispersions are found commonly in nature and industry. As these dispersions flow, the microstructure changes due to deformation and breakup processes at the microscale. The ability to predict this microstructural evolution has many applications, including controlling properties in …
