Summary: The artificial construction of nature-mimic inorganic-organic heterostructures for protective surface applications involves the synthesis of zinc oxide nano-spicules grown from polylactic acid templates, leading to super-hydrophilic and bactericidal surfaces. The interfacial assembly of entrapped ZnO nanoparticles allows for the growth of nano-spicules, inducing super-hydrophilicity and enhancing bactericidal activity in a new and effective way.

Summary: This study used atomic force microscopy to investigate the morphology and interactions of interfacial nanobubbles (INBs) with different surfaces. It was found that the hydrophilic probe is essential for scanning the complete morphology of INBs, and a positive correlation between INB vertical height and applied force was observed. Additionally, the interaction between INBs and hydrophobic surfaces was significantly stronger compared to hydrophilic surfaces.

Summary: In this study, molecular dynamics simulations were performed to investigate the decomposition of methane hydrates in the nanopores of graphite and hydroxylated-silica surfaces. The results showed that the solid surface can enhance hydrate decomposition, with a stronger effect observed for the hydroxylated-silica surface. Additionally, the decomposition rate was found to be higher at lower temperatures on the hydroxylated-silica surface compared to the graphite surface. These findings provide a theoretical basis for the safe and efficient exploitation and transportation of hydrates in marine sediments.

Summary: Microsecond molecular simulations were conducted to investigate the impact of surface properties on CO2 hydrate formation in slit-nanopores of graphite and hydroxylated-silica surfaces. The results showed that different surface properties affect hydrate formation primarily by altering the aqueous CO2 concentration. Hydrophobic graphite surfaces adsorbed CO2 molecules strongly, reducing the aqueous CO2 concentration, while hydrophilic silica surfaces led to high aqueous CO2 concentration due to the adsorption of CO2 nanobubbles.

Summary: This study presents a strategy for surface modification combining hydrophobicity and pH-sensitivity by using all-aqueous layer-by-layer (LbL) deposition of polyelectrolytes. The hydrophobic coatings created through this method can detect and respond to changes in environmental pH and enable precise droplet manipulation. The films exhibit excellent parahydrophobic behavior and can be used in various applications such as microfluidics and water harvesting.

Summary: Noise and environmental problems have significant impacts on human beings through various stressors. To address these issues, environmentally friendly strategies are essential, particularly in materials manufacturing. This study presents a novel biomimetic and biophilic design of a lichen-Schwarz metamaterial (SLSM) that achieves multifunctional properties in noise attenuation and humidity control. The SLSM structure mimics a biomimetic shell and meta-symbiotic exoskeleton, providing sound attenuation and humidity control capabilities for future sustainable architecture.

Summary: A hydrophilic konjac glucomannan (KGM)/ hydrophobic ethyl cellulose (EC) film was prepared in an ethanol/water environment. The study found that higher ethanol usage enhanced the stability of the film-forming solution but did not improve the film properties. The ethanol content and evaporation affected the molecular interaction during film formation.

Summary: First, nano-sized magnesium oxide particles were prepared using magnesium nitrate hexahydrate and Angelica dahurica extract. Then, the particles were loaded on cotton fabric, and the fabric was hydrophobically modified using hexadecyl trimethoxysilane and ammonia as a catalyst. The modified fabric showed a high water contact angle and excellent antibacterial properties against S. aureus and E. coli. It also demonstrated good washing durability.

Summary: Surface wetting significantly influences material performance and applications, with superhydrophobic surfaces exhibiting water repellency due to their low surface energy chemistry and micro/nanostructure roughness. The next generation of superhydrophobic surfaces, Multifunctional SHSs, are rapidly evolving with properties including self-healing, anti-bacterial, anti-fouling, and stimuli responsiveness. Designing durable Multifunctional SHSs with self-healing functions can enhance performance and lifespan, with a focus on parameters such as durability, stability, more functions, responsiveness, and environmentally friendly features.

Summary: A versatile method for the creation of multitier hierarchical structured surfaces is reported, which optimizes both antiviral and hydrophobic properties. This methodology has significant advantages, such as overcoming the droplet-pinning effect, delivering surfaces with high contact angles and good antiviral efficacy, and creating mechanically robust, nanostructured surfaces using nonspecialized equipment.

Summary: Magnetite is an iron-rich carrier that can enhance the activity and aggregation of anammox bacteria. In this study, different-sized samples from a granulation reactor were used, and it was found that larger granules had higher iron content and improved microbial cell density. The specific anammox activity increased with granule size, and the heme c content was also higher in larger granules. The extracellular polymeric substances (EPS) analysis showed differences in secretion intensity and protein structures among the different sizes. The relative abundance of Brocadia Sinica also increased with granule size. This study highlights the importance of in-depth EPS analysis beyond traditional yield and major content analysis.
