Natural wood possesses a hierarchical and three-dimensional (3D) interconnected microstructure, making it a desirable material for water treatment. However, limited water transport pathways can reduce the efficiency of removing high-concentration organic dyes. To address this, we present a low-cost, scalable, and efficient cross-flow Ag/wood composite filter by combing the structural design and hydrothermal treatment using a silver-ammonia solution. Silver ions (Ag<sup>+</sup>) are effectively reduced to silver nanoparticles (Ag NPs) by wood lignin and then anchored by hydroxyl groups in the cellulose and hemicellulose of the wood. Importantly, the incorporation of Ag NPs does not compromise the 3D porous structure of the wood. Diagonal grooves and exposed channels on both sides of the filter guide pollutants, ensuring extensive interaction with Ag NPs along elongated reaction pathways and through microstructural vessel disturbances. An 8 mm-thick cross-flow Ag/wood composite filter, featuring grooves with a diameter of 15 mm and a depth of 4 mm, achieves a remarkable 99% degradation efficiency of methylene blue (MB) at a water flux of up to 1775 L/(m<sup>2</sup>∙h). The performance in water flux and decolorization efficiency hinges significantly on groove diameter, groove depth, and filter thickness. This cross-flow Ag/wood composite filter represents a promising advancement for rapid and effective removal of various organic pollutants in a single-step process, showcasing extensive potential for applications in water treatment. This work aims to enhance clarity and readability while maintaining the technical details and impact of the research.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"59 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, WS shows remarkable mechanical robustness, enduring 1000 stress-strain cycles with high shape recovery, ensuring its durability under operational conditions. The data highlight several strengths of MnO<sub>2</sub>/WS, including cost-effective production process, high reusability, remarkable sorption capacities for carbon tetrachloride and soybean oil (29.56 and 17.65 times its mass, respectively), and efficient performance.

Tests evaluated tensile and compressive properties in three directions, alongside shear strength and bending properties. Acoustic emission (AE) and digital image correlation (DIC) techniques probed damage evolution under bending loads before and after HIMW treatment. As microwave energy density increased, compressive, tensile, and shear strength decreased, with heartwood being the most susceptible. Substantial reductions occurred in longitudinal compressive properties and tensile properties perpendicular to the grain. After HIMW treatment (80 kWh/m<sup>3</sup> and 100 kWh/m<sup>3</sup> for sapwood and heartwood, respectively), although there was a slight decrease in the modulus of elasticity and bending strength, there was a significant increase in bending plasticity. HIMW-treated specimens exhibited more high-frequency AE signals during elastic–plastic deformation, indicating more frequent fractures in the treated wood during three-point bending. Changes in the microscopic structure of the wood specimens caused by HIMW treatment increased the damage growth rate and stress redistribution efficiency during loading, augmenting the bending plasticity of wood.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"58 5-6","pages":"2073 - 2096"},"PeriodicalIF":3.1,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142453105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Formaldehyde consumption was estimated via titration of the oximated free formaldehyde; the hydroxy-methylation degree under the reaction was estimated by calculating the ratio in Condensed hydroxyl/Guaiacyl (Condensed OH/G-OH) via a new difference UV-spectroscopy. The reliability of the difference UV-method results for the analyses of the hydroxy-methylated lignins was statistically analysed and compared with that of vacuum-dried and sonicated samples.

The study utilized molecular dynamics (MD) simulations to quantitatively investigate the hydrothermal effect on the degradation of CNC interface. The degradation mechanism induced by moisture and temperature was indicated through the reduction of adhesive energy and peak force with the consideration of hydrogen bonds. The simulation results showed that the role of water molecules in the interfacial failure depends their content. Water acted as a binder at low moisture levels, while at high moisture levels, it acted as a lubricant. Besides, temperature had a more pronounced impact on the interfacial shear performance.
