Summary: Complex pollutants in rivers and oceans can be efficiently treated using C,N co-doped TiO2 hollow nanofibers coated stainless steel meshes, which enable oil/water separation and visible light-driven dyes photodegradation. The functional mesh is obtained by generating poly(divinylbenzene-co-vinylbenzene chloride) nanofibers on the mesh framework and coating them with TiO2 through a sol-gel process. The resulting mesh demonstrates superhydrophilic/underwater superoleophobic property and high photodegradation ability to dyes under visible light. This work presents a cost-effective and high-performance multifunctional mesh for potential applications in wastewater treatment.

Summary: This article introduces a fluoride-free UV-responsive material for oil/water separation and dye degradation. Environmentally friendly and low cost materials such as cellulose, silicon dioxide, titanium dioxide, and stearic acid were used to fabricate a superhydrophobic coating that can transition from superhydrophobic to superhydrophilic under UV irradiation. The coated cotton fabric can effectively separate oil/water mixtures and emulsions.

Summary: This article proposes a facile one-step method for forming silver thin-film nanostructures on Al2O3 substrates using the hydrothermal method. The study shows the dependency of the SERS effect intensity of the formed films on synthesis conditions, additional temperature treatment, and laser radiation wavelength. The article also demonstrates the effect of synthesis temperature on the particle size, crystal structure, and microstructure features of the obtained thin films based on silver nanoparticles. Additionally, the study reveals the factors associated with the properties of the obtained SERS substrates and the parameters of recording the spectra that affect the amplification factor of the spectral lines intensity of the analyte.

Summary: In this paper, low-cost electrochemical processing and heat treatment were used to fabricate titanium alloy surfaces with switchable wettability. The effects of surface structure, roughness, oxide content, temperature, and time of heat treatment on switchable wettability were investigated. Surface chemistry of electrochemical processed surfaces was changed by organic matter transfer during heat treatment. The hypothesis that the concentration difference promotes organic matter transfer was proposed and verified by experiments. The electrochemical processed surfaces with switchable wettability were obtained through organic matter transfer in two ways.

Summary: Micro/nano-textured metal or metal oxide surfaces undergo a wettability transition from superhydrophilic to hydrophobic when exposed to ambient air. This transition affects surface evaluation and performance. A solvent cleaning method is proposed to restore the superhydrophilicity while maintaining the surface morphology and composition. Dense surface nanostructures delay the wettability transition by suppressing organic molecule diffusion.

Summary: Superwetting properties with multiple superlyphobic states have unique advantages in specific interfacial applications. However, there is currently a lack of systematic research on fine controlling superwetting surfaces. Controllable fabrication of superoleophobic surfaces from superhydrophilicity to superhydrophobicity in oil is still a challenge due to the harsh conditions involved.

Summary: The photoinduced hydrophilic behavior of TiO2 thin film synthesized by atomic layer deposition method on p-Si wafer and SiO2-coated glass has been studied. The significant difference in hydrophobicity between the TiO2 film on SiO2-coated glass and the Si wafer is attributed to the formation of a type-II TiO2-Si heterostructure. The role of photoelectrons in the mechanism of light-induced hydrophilic conversion of the TiO2 surface was elucidated.
