pH/temperature-responsive salt-tolerant Pickering emulsion formed by PNIPAM-modified chitosan particles

Tengfang Zhang et al.

Summary: In this study, chitosan was modified with PNIPAM to enhance its surface activity and temperature response. The CS-PNIPAM emulsion showed excellent emulsification performance in various oil phases. The addition of salt ions improved the stability of the emulsion. pH and temperature also affected the stability of the emulsion, with low pH causing emulsion breakage and high temperature leading to emulsion aggregation and breakage.

Magnetic Nanomotors in Emulsions for Locomotion of Microdroplets

Boris Kichatov et al.

Summary: This paper investigates the locomotion of droplets in emulsions under a nonuniform magnetic field. It is found that the mechanism of droplet locomotion largely depends on the wettability of magnetic nanoparticles (MNPs), with hydrophobic MNPs forming agglomerates and hydrophilic MNPs forming dispersed mobile magnetic clusters. These results have potential applications in drug delivery.

Lignin Nanoparticles as Highly Efficient, Recyclable Emulsifiers for Enhanced Oil Recovery

Kai Gao et al.

Summary: Emulsification is an important process in chemical flooding for enhanced oil recovery (EOR), and the use of lignin nanoparticles (LNPs) as Pickering emulsifiers shows improved interfacial activity and emulsification ability. LNPs can form stable Pickering emulsions with kerosene at various concentrations and store them for up to 6 months. Additionally, rapid oil-water separation can be achieved by alkali demulsification due to the pH responsive nature of lignin, enabling the reuse of lignin suspension under pH control.

Development of recyclable pH-responsive magnetic nanospheres via RAFT polymerization and their application in Pickering emulsions

Keran Li et al.

Summary: In this study, a controllable and efficient method for preparing dual-stimulus-responsive magnetic nanospheres as particle emulsifiers was described. The nanospheres showed pH and magnetic responsiveness, and the emulsion stability could be controlled by changing pH value or applying an external magnetic field. The stability and destabilization of the emulsion were influenced by factors such as polymer segment length, particle concentration, water-oil ratio, and oil phase polarity. This research provides opportunities for applications in oily wastewater treatment, water-oil separation, and crude oil delivery systems.
