Summary: CO2-switchable surfactants have selective surface-activity that can be activated or deactivated by adding or removing CO2. They are mainly cationic and can be activated by the protonation of a nitrogen-containing group upon sparging CO2 gas. CO2-switchable superamphiphiles can be formed by non-covalent bonding between components at least one of which is CO2-switchable. So far, CO2-switchable surfactants have been used in various types of colloids such as spherical and wormlike micelles, vesicles, emulsions, foams, and Pickering emulsions.

Summary: The study discusses the influence of surface roughness frequencies and parameters on mixed wetting and its transitions. It was found that while all roughness frequencies contribute to net roughness parameters, not all of them affect wettability transitions. Parameters such as Rz and LSm were identified as predictors for spatial roughness frequencies that dictate transitions to different wettings states.

Summary: There is growing concern about developing biobased colloid particles for Pickering stabilization due to their environmental friendliness and health safety. In this study, Pickering emulsions were formed using cellulose nanofibers and chitin nanofibers, and their physico-chemical characteristics were investigated. The results showed that higher concentrations and surface wettability of the nanofibers led to better stabilization of the emulsions. These findings provide important information for the formulation of Pickering emulsions using polysaccharide nanofibers with suitable properties.

Summary: This research investigates the impact of magnetite nanoparticles on the surface properties of silica during asphaltene precipitation. The results show that heteroatoms and aromatic rings in asphaltene affect its agglomeration and adsorption process. The presence of magnetite nanoparticles reduces the contact angle of pure silica upon asphaltene precipitation, making the silica surface preferentially oil-wet.

Summary: The experimental investigation showed significant improvements in boiling heat transfer coefficient and critical heat flux at a mass fraction of 0.1% for Al2O3 and TiO2 nanoparticles in water. An increase in mass fraction improved the surface wettability of nanofluids and reduced the surface roughness of the boiling surface. Al2O3-water nanofluids exhibited better boiling performance compared to TiO2-water nanofluids.

Summary: This article reports a new method that can control surface wettability in situ. Thiol molecules adsorbed onto gold were found to be able to change the contact angles of liquids when an electric current was provided, without ionizing the dipoles. Mixing ethanethiol with the thiol molecules allowed for further control of the contact angles. The mechanism of the conformation change induced in this article was most likely due to the dipole-electric current interaction.

Summary: Self-cleaning of textile fabrics refers to the ability to remove pollutants particles from the fabric surface without any external source. The application of this technology is environmentally beneficial as it conserves water, energy, and laundry costs. Chemical coatings have traditionally been used for self-cleaning, but recent advancements in 3D printing technology have posed challenges for printed fabrics. A recent study has established a regression model to analyze the impact of primary printing parameters on self-cleaning attributes.

Summary: This study investigates the wetting behavior and hydrophobic mechanism of 304 stainless steel surface and Ni-Cu-P coatings, showing that the water contact angle change is associated with surface area and surface roughness. The recovery of water repellency is influenced by a time constant related to micro-scale surface deformation or roughness. The research provides a theoretical basis for time-dependent wetting studies.

Summary: This study used medical X-ray computed tomography (CT) to image water-wet and oil-wet Indiana limestone core samples before and after CO2 flooding. The results showed that both water-wet and oil-wet cores experienced dissolution and an increase in pore volume after core flooding with live brine and subsequently CO2. Additionally, the oil-wet rock had a lower reactivity compared to the water-wet rock.

Summary: Renewable energy, especially hydrogen, can be the optimal solution to replace fossil fuels and achieve net-zero carbon emissions and mitigate global warming. One challenge in the hydrogen industry is the safe and economical storage of hydrogen. Underground geological storage is a potentially suitable solution for large-scale and long-term hydrogen storage. However, there is still a lack of research on the geochemical reactions associated with hydrogen wettability alteration in subsurface sandstone reservoirs. This study utilizes surface complexation modeling to understand the hydrogen wettability on quartz surface and provides a framework for evaluating the feasibility of underground hydrogen storage in depleted sandstone reservoirs.

Summary: Controlled salinity water flooding, or engineered water flood, is a potential enhanced oil recovery (EOR) method that has been tested in laboratory and at pilot/field scale. However, there have been cases where this method failed to show its potential for EOR, mainly due to a lack of understanding of the underlying mechanism specific to each case.

Summary: This study calculated the interfacial tension parameters between clay and gas as well as clay and brine at different temperatures and pressures. The results showed that the interfacial tension between clay and hydrogen gas was higher than that between clay and nitrogen gas or carbon dioxide gas under similar thermodynamic conditions. Additionally, a significant relationship was found between clay/gas interfacial tension and gas density, which could be a useful tool for estimating rock/fluid interfacial tension quickly.
