Summary: Four-dimensional (4D) printing is a form of 3D printing technology that utilizes additional stimulus and stimulus-responsive materials, such as temperature-sensitive polymers like poly-N-vinylcaprolactam. This study aims to alter the phase transition temperature of poly-N-vinylcaprolactam hydrogels by incorporating two additional monomers, vinylacetate and N-vinylpyrrolidone, through photopolymerization. The findings show that the inclusion of N-vinylpyrrolidone increases the lower critical solution temperature above the physiological range, while the incorporation of vinylacetate decreases it to allow for self-assembly of 4D-printed objects at room temperature.

Summary: The paper discusses the enhancement of hydrophilicity and anti-biofouling properties of polymer coatings through PEG-modification. By incorporating a limited amount of a low-surface energy dangling chain, the surface concentration of PEG can be significantly increased, leading to a lower water contact angle. The study also proposes a mechanism for this observation and validates it through various experiments, demonstrating the potential of mixed hydrophobic/hydrophilic dangling chains strategy for low-protein adsorption applications.

Summary: In this research, a novel light-trapping texture on the surface of bio-hydrogel was presented, which improved solar absorption through a low-cost fabrication method. The light-trapping textures effectively converted solar irradiance into heat energy with minimal reflection loss, resulting in enhanced photothermal energy conversion efficiency compared to flat surfaces. Under 1 sun illumination, a superb seawater evaporation rate of 2.851 kg m(-2)h(-1) and an evaporation efficiency of 91.17 % were achieved. The decoration of bio-hydrogel with TaTe2 quantum dots exhibited remarkable antibacterial and anti-biofouling properties, with reduction rates exceeding 95 %.

Summary: Water-mediated interactions play important roles in aqueous solutions, affecting processes such as protein folding and nanoparticle aggregation. This study investigates the impact of temperature and pressure on different types of interactions between graphene-based surfaces. The results show that hydrophobic, hydrophilic, and hybrid interactions are all sensitive to pressure, while only hydrophobic interactions are significantly affected by temperature variations. The findings have implications for understanding protein denaturation and biomolecular interactions, as well as for the design of water models for molecular and nanoparticle systems under different thermodynamic conditions.

Summary: The hydrophobicity found in rare-earth oxides is intriguing. Despite its hydrophilic nature, the CeO2 (100) surface exhibits hydrophobic behavior when immersed in water. A detailed analysis of the water structure and dynamics reveals that the first water layer in contact with the hydroxylated CeO2 surface acts as a hydrophobic interface. This discovery introduces a new concept of hydrophobicity mediated by specific water patterns on a hydrophilic surface in water/rare-earth oxide interfaces.

Summary: This study reports an innovative strategy to achieve longer antifogging duration by enhancing the water absorption capacity of the coating. The combination of strong interfacial adhesion and hydrophilic/hydrophobic heteronetwork structure is key to this approach, which avoids interfacial failure and swelling-induced wrinkles under typical fogging conditions. Moreover, the coating also has potential as underwater glues.

Summary: In this study, a thin layer of diverse synthetic hydrogels was applied on polyethylene terephthalate (PET) track-etched membrane and conventional polyethersulfone (PES) ultrafiltration membrane to study their anti-biofouling properties. The hydrophilicity, roughness, and surface charge had a minor effect on algae fouling, while the degree of swelling of the attached hydrogel played a role in biofouling control. After 11 months of operation in a membrane bioreactor (MBR), the module equipped with hydrogel modified membranes showed higher permeability compared to the reference membranes.

Summary: Nanoconfinement effect has a significant impact on chemical reactivity. Chemists have designed various porous nanoconfined systems for catalyzing reactions, but achieving effective flow reactions under mild conditions remains challenging. In this study, multilayer aminated graphene oxide (GO-NH2) membranes were prepared to achieve rapid and efficient Knoevenagel condensation with directional flow. By reducing the interlayer spacing of GO-NH2 membranes, the conversion of the reaction increased, reaching nearly 100% at 22 degrees Celsius with a short reaction time when the interlayer spacing was 14.7 angstroms. Mechanistic studies showed that interlayer confinement enhanced the matching of reactants' frontier orbital symmetry. The characterization of catalysts and density functional theory calculation demonstrated that the delocalized pi electrons of graphitic domains on GO-NH2 could reduce the overall confined reaction energy level. This work provides insights for constructing artificial catalytic systems with high conversion under mild conditions.
