CO 2-switchable surfactants have selective surface-activity, which can be activated or
deactivated either by adding or removing CO 2 from the solution. This feature enables us to …

The use of different types of chemicals in upstream oilfield operations is critical for optimizing
the different operations involved in hydrocarbon exploration and production. Surfactants are …

CO 2/N 2 switchable surfactants have recently attracted significant attention in enhanced oil
recovery. Their environmental and economic benefits are the main driving forces for their …

Emulsification and separation are of great significance in oil recovery. Herein, we report a
synergic system of polymers and silica particles, which can achieve the emulsification and …

Chitin has a unique hierarchical structure, spanning the macro-and nanoscales, and
presents chemical characteristics that make it a suitable component of multiphase systems …

Responsive Pickering emulsions are an excellent platform to control the interfacial
properties of oil–water systems. However, the removal of viscous crude oil from oily waste by …

Hybrid smart emulsification systems are highly applicable in manipulating oil-in-water (O/W)
droplets. Herein, novel switchable block polymers containing both zwitterionic and tertiary …

Pyrolysis of marine biomass (MB) to create marine biomass-derived carbon materials
(MBCs) for industry is a sustainable solution. In this study, we systematically examined …

Thermal recovery techniques for producing oil sands have substantial environmental
impacts. Surfactants can efficiently improve thermal bitumen recovery and reduce the …

Surfactants are extensively employed in the cold production of heavy oil. However,
producing heavy oil emulsions using conventional surfactants poses a challenge to …
