Although heat treatment can improve those wood properties, the material remains susceptible to photodegradation under prolonged ultraviolet (UV) exposure, which limits its applicability in outdoor environments. In this study, ZnO was deposited onto the surface of heat-treated Taxodium hybrid ‘Zhongshanshan’ wood via magnetron sputtering to improve its resistance to light-aging. Results revealed that the ZnO coating was uniformly deposited with well-defined crystallinity and it did not compromise the visibility of the wood’s natural texture. After sputtering for 120 min, the light-aging resistance of heat-treated wood improved significantly. For example, the color difference (ΔE) decreased by about 50% as compared to the uncoated wood after light aging. By the way, the coating also can improve the waterproofing of wood surface, such as the initial water contact angle only decreased from 139.5° to 122.8° after light aging. Comprehensive characterization by SEM, XPS, EPR, and UV-Vis demonstrated that the ZnO coating inhibited the formation of free radicals and surface oxidation, thereby enhancing the wood’s resistance to UV-induced photodegradation. These findings highlight the effectiveness of magnetron sputtering as a physical modification approach for improving the long-term weathering performance of heat-treated fast-growing wood.</p>\u0000 </div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"60 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145729893","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}

However, the microstructure of lignin-derived electrode materials obtained through traditional methods limits the effective utilization of energy storage capacity, resulting in a significant loss of electrochemical efficiency. Doping with heteroatoms in lignin-derived carbon can enhance its electrochemical performance and is a promising method for performance improvement. We employed a green and universal approach to design lignin-derived carbon materials by covalently grafting phosphorus source (DOPO) and nitrogen source (HDI) onto the lignin macromolecular framework through organic synthesis. Using modified lignin (NPAL) as a precursor, we achieved simultaneous carbonization and activation through a one-pot method. The nitrogen and phosphorus doping synergistically enhances pseudocapacitance activity (redox reactions), optimizes the hierarchical pore structure (increasing the specific surface area to 1756.79 m²/g), and improves charge transfer kinetics (reducing charge transfer resistance to 6.63 Ω). This results in a high specific capacitance (276.3 F/g @ 0.25 A/g, an increase of 275.56% compared to undoped materials), high energy density (12.5 Wh/kg), and cycling stability (capacity retention of 92.5% after 10,000 cycles), indicating a promising application prospect.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"60 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145729674","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}

In this research, 20 <i>Q. infectoria</i> trees (10 healthy and 10 infected) were selected. Trunk and branch samples from each tree were collected and analyzed in the laboratory. Fiber separation for morphological property assessments was conducted using Franklin’s method, and chemical composition analyses of the wood were carried out based on TAPPI standards. Data analysis involved checking normality using the Kolmogorov-Smirnov test, followed by one-way ANOVA and Tukey’s post-hoc test for comparisons. The results showed that the presence of <i>L. europaeus</i> significantly affected certain morphological properties, leading to reduced fiber diameter and cell wall thickness while increasing cell lumen diameter in both trunks and branches of the host. It had a significant impact on morphological coefficients, causing an increase in the flexibility ratio, and a decrease in the Runkle ratio. In terms of chemical properties, <i>L. europaeus</i> significantly decreased hemicellulose and increased lignin and extractives content, while its effect on other components was not statistically significant. These findings suggest that <i>L. europaeus</i> reduces fiber diameter, increases cell lumen diameter, and decreases cell wall thickness, resulting in diminished mechanical strength of the wood. Additionally, the reduction in hemicellulose and changes in extractive content significantly affect the industrial quality of <i>Q. infectoria</i> wood. This study demonstrates that <i>L. europaeus</i> infestation has profound impacts on both the structural integrity and industrial quality of <i>Q. infectoria</i> wood, providing key insights for sustainable forest management and utilization.</p>\u0000 </div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"60 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145613140","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}

This study focuses on bleaching processes as an alternative to conventional delignification, aiming to retain a significant amount of lignin while achieving the desired whiteness of the wood template. In particular, stabilized alkaline hydrogen peroxide is investigated as a bleaching agent under mild conditions. The treatment preserves more than 90% of the native mass in both balsa and birch, ensuring that most of the wood’s structural components are maintained. This results in a high wood volume fraction, corresponding to reduced porosity and a structure closely resembling that of unbleached wood. Fourier Transform Infrared spectroscopy (FTIR) semi-quantitative analysis further confirms that the relative lignin content is retained, ranging between 70 and 80% depending on the species. Unlike conventional approaches that often degrade the wood structure and require long treatment times at high temperatures, the proposed process is performed at room temperature under mild conditions and completed in less than 2–4 h, thus reducing energy demand and avoiding harmful byproducts. Overall, this work provides a bleaching strategy that combines efficiency, structural integrity, and sustainability, offering bleached wood templates suitable for further characterization and advanced applications.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"60 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00226-025-01725-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145561316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this standard model for lignin formation is challenged by certain lignin structures that cannot be easily explained by this theory. One such structure characterized by a side chain carbon (α or β-position) linked to an aromatic C6 is the focal point of this minireview.
