Abstract ：
Wood surface superhydrophobic modification effectively mitigates liquid-water-induced shrinkage/swelling, enhancing dimensional stability. However, most researches focus on wood transverse sections due to inherent roughness, whereas few have achieved superhydrophobicity on environmentally exposed tangential surfaces. Furthermore, practical application of superhydrophobic wood remains challenging due to its poor interfacial stability. Herein, a scalable alkali etching strategy that partially removes hemicellulose/lignin to enhance roughness and active sites on wood tangential surfaces is proposed. Subsequent spraying of hydroxyapatite-polydimethylsiloxane (HAP-PDMS) composite solution forms a robust superhydrophobic coating. Etching-induced microcracks and voids facilitate nanoparticle anchoring, synergistically functioning with the cellular framework as a protective barrier to ensure exceptional durability. The modified surface can withstand mechanical abrasion, chemical corrosion, and UV exposure, retaining superhydrophobicity after 60-day outdoor aging. Notably, it exhibits autonomous self-healing: post seven abrasion-repair cycles, the water contact angle recovers to 142 degrees (92.4% restoration efficiency). This work provides an economical route to engineer stable superhydrophobic tangential wood surfaces, extending product service life.

Abstract ：
Thin films with adjustable refractive indices are crucial for fabricating multi-layer antireflective coatings (ARCs). Conventional sol-gel methods typically require the incorporation of templates or modifiers to precisely control film porosity and refractive index. In this work, we propose a template-and modifier-free sol-gel method to precisely engineer the chemical-and micro-structure of silica nanoparticles (SNPs), enabling the fabrication of silica thin films with tunable refractive indices ranging from 1.15 to 1.38 using only tetraethoxysilane (TEOS), ethanol, ammonia water, and water as raw materials. By simply adjusting NH3 center dot H2O and H2O content, the hydrolysis and condensation of TEOS can be controlled to obtain SNPs with adjustable chemical-and microstructure, which enable the control of inter-particle and intra-particle porosity. It is found that at low NH3 center dot H2O content, the resulting SNPs exhibit a surface abundant in hydrophobic ethoxy groups, which effectively reduce the capillary pressure within a thin film during the drying process, thereby inhibiting the film shrinkage, increasing the porosity, and ultimately producing a hydrophobic film with a refractive index as low as 1.15. Conversely, with high NH3 center dot H2O content, the resultant SNPs have few hydrophobic ethoxy groups on their sur-face, exhibiting excellent hydrophilicity. The resultant increased capillary pressure induces significant film shrinkage during the drying process, resulting in a thin film with low porosity and high refractive index. Finally, leveraging this tunability of refractive index, we successfully fabricated a double-layer hydrophobic broadband ARC with excellent optical performance, where the thin films prepared with high and low NH3 center dot H2O contents were integrated as bottom and top layers, respectively.

Abstract ：
Poor mechanical stability of superhydrophobic coating limits its practical application. In this work, robust superhydrophobic organically modified silicate (ORMOSIL) hybrid coatings were fabricated on wood surface by a chemical-assembly engineering induced by click reaction of PMHS. The superhydrophobic ORMOSIL coating was hybridized from poly(methylhydrogen)siloxane (PMHS), tetravinyltetramethylcyclotetrasiloxane (V4), and silica nanoparticles (SNPs). The click reaction between PMHS and SNPs built a chemically bonded rough surface with very low surface energy, while click reaction between PMHS and V4 resulted in a strong glue of adjacent SNPs, endowing ORMOSIL hybrid coatings with good mechanical stability. Chemical-assembly engineering afforded ORMOSIL coatings superhydrophobicity, self-cleaning property, and good robustness, and the unique physical characteristic of ORMOSIL also gave superhydrophobic coatings excellent resistance to UV light, high and low temperature, and humid and salt mist environments. Finally, chemical-assembly engineering had been demonstrated to be applicable in fabrication of superhydrophobic coating on various substrates containing hydroxyl groups and various nanoparticles could be applied to replace SNPs.

Abstract ：
Rechargeable aqueous zinc-ion batteries (AZIBs) are promising candidates for stationary energy storage owing to their intrinsic safety, environmental sustainability, and cost-effectiveness. However, their cycling stability is hampered by uncontrollable dendrite formation and hydrogen evolution reactions (HERs) at the Zn anode. Herein, we propose a cost-effective commercial viscose fabric derived from profiled viscose rayons as a versatile separator for reconfiguring the interface dynamics of Zn deposition, enabled by the surface grooves with abundant carboxyl groups on the profiled viscose rayons. Results show that carboxyl groups facilitate the desolvation of hydrated Zn2+ to suppress HERs, while the surface grooves provide epitaxial Zn2+ pathways for rapid horizontal transport of Zn2+ on the surface of the Zn anode, which promotes the transition of the Zn deposition manner from 2D to 3D diffusion and regulates the growth direction of Zn crystals from (101) to (002) to form uniform and dense Zn deposition on the anode. Consequently, AZIBs implementing the viscose fabric separator exhibit high battery performance, including an improved cycle life of over 4600 h at 1 mA cm-2 and enhanced rate capability. This work highlights the significant potential of profiled viscose rayon in reconfiguring the interface dynamics of Zn deposition, providing guidance for the design of advanced separators in AZIBs.

Abstract ：
The development and evaluation of a novel separator material for aqueous zinc-ion batteries (ZIBs) are discussed, which are promising for energy storage due to their use of abundant zinc metal, eco-friendly electrolytes, and high safety. The main challenges in ZIBs are the formation of zinc dendrites and the hydrogen evolution reaction (HER), which can lead to short circuits and reduced battery life. To address these issues, the authors have functionalized chitin separators through a process involving alkaline treatment and mechanical grinding, resulting in nano-chitin fibers with varying degrees of deacetylation (D-x-ChNF). The D-4-ChNF separator, in particular, has been shown to have uniformly distributed nanochannels, high mechanical strength, and excellent electrochemical stability. It also exhibits a strong affinity for aqueous ZnSO4 electrolytes and enhances the electrochemical reversibility of zinc through increased coordination with Zn2+ ions. This leads to a significant improvement in the battery's cycle life, with the D-4-ChNF separator outperforming traditional glass fiber (GF) separators by more than six times in cycle life at 5 mA cm-2 and 5 mAh cm-2. The D-4-ChNF separator also demonstrates superior rate performance and long-term cycling stability, with capacity retention rates of 90.46% and 96.68% after 1000 cycles at 5 A g-1 and 10 A g-1, respectively. The separator's ability to suppress dendrite growth and improve the uniformity of zinc deposition is attributed to its ability to reduce nucleation overpotential and promote uniform zinc deposition along the (002) crystal plane. The D-4-ChNF separator, with its low cost and high stability, offers a promising solution for enhancing the performance and practical application of ZIBs, providing new insights into the development of efficient and sustainable energy storage technologies.

Abstract ：
The oil/water separation material is beneficial to the respective detection of organic and inorganic impurities in samples by retaining the water-soluble impurities in water and the liposoluble impurities in the oil phase. Cotton fiber@SiO2 superhydrophobic fabric was prepared by a facile modifier-free sol-gel method for oil/water separation. By adjusting the hydrolysis and condensation of TEOS, the preparation of superhydrophobic and superhydrophilic fabrics can be achieved. The hydrolysis and condensation of TEOS are simply controlled by changing the content of ammonia water (as a catalyst). When the content of ammonia water is 3-6 %, cotton fiber@SiO2 superhydrophobic fabric was obtained with the water and oil contact angle of similar to 156 degrees and 0 degrees, respectively. When the content of ammonia water is 7-10 %, cotton fiber@SiO2 superhydrophilic fabric was realized. In addition, the as-prepared cotton fiber@SiO2 superhydrophobic fabric can be used for the separation of oil/water mixtures with a separation efficiency of 98 %. Finally, the mechanism for the modifier-free sol-gel preparation of cotton fiber@SiO2 superhydrophobic and superhydrophilic fabric was discussed.
