Summary: This study reports a wet adhesive composed of a single-component poly(ionic liquid) (PIL) that enables fast and robust underwater adhesion. The PIL adhesive film possesses excellent stretchability and flexibility, achieving anchoring on target substrates regardless of deformation and water scouring. The wet adhesion capability of PILs is attributed to the synergy of different non-covalent interactions, such as hydrogen bonding, cation-N, electrostatic, and van der Waals interactions, as revealed by surface force measurements. Surprisingly, the PIL adhesive film also exhibits impressive underwater sound absorption capacity.

Summary: The addition of B-sites breaks the trade-off between promoted exsolution and suppressed phase transition, expanding the application range of exsolution-facilitated perovskite materials. Using carbon dioxide electrolysis as a case study, this research shows that the catalytic activity and stability of perovskites with exsolved nanoparticles (P-eNs) can be enhanced by regulating the phase of host perovskites, emphasizing the important role of perovskite scaffold in catalytic reactions occurring on P-eNs. This concept may lead to the design of advanced exsolution-facilitated P-eNs materials and uncover a wide range of catalytic chemistry on P-eNs.

Summary: Infections can have serious health consequences, including death. Surfaces, such as biomedical devices, implants, textiles, tables, and doorknobs, serve as carriers for pathogens to move, attach, and multiply. Implementing antimicrobial surfaces is a reliable and long-lasting approach to combat surface transmission of germs, reduce microbial colonization, and decrease infections. This review presents recent advancements in antimicrobial surfaces, categorized into four groups based on their mechanisms of action: antifouling, bactericidal, antifouling and bactericidal, and dynamic or stimuli-responsive surfaces. The review discusses the fabrication processes and properties of each category, along with their structure-performance relationships. Special attention is given to various anchoring strategies involving tunable molecular interactions. Relevant biomedical applications are also introduced.

Summary: The effects of polyethylene oxide (PEO) dosage and solution pH on the flocculation, rheological and surface/interfacial properties of the slurry were investigated. The study found that the settling rate of the tailings was lowest in strongly acidic solutions and reached its peak in strongly alkaline solutions. PEO dosage had a modest impact on the yield stress in strong acid solutions, but a notable influence in neutral and strongly alkaline solutions. The adsorption of PEO chains on silica surfaces was enhanced in strong alkaline solutions and partially inhibited in strongly acidic solutions. Surface force measurements showed that PEO chains can bridge the tailings particles, increasing the suspension's yield stress.
