This study pioneered a novel hierarchical composite architecture integrating ball-milled <i>Melaleuca</i> bark-derived activated carbon (BAC) with nickel-cobalt layered double hydroxide (Ni-Co LDH) via a facile solvothermal method. Systematic optimization of synthesis parameters including the Ni: Co molar ratio, solvothermal reaction temperature/duration, and the BAC to NiCo-LDH mass ratio unveiled that controlled conditions induced a distinctive urchin-like spherical morphology, where vertically-aligned LDH microspheres uniformly anchor onto the porous BAC scaffold. This unique structure fosters a synergistic dual-function: BAC serves as a conductive backbone that mitigates LDH aggregation and enhances ion transport kinetics, while Ni₃Co₆-LDH delivers robust pseudocapacitance. Crucially, the optimal BAC/Ni<sub>3</sub>Co<sub>6</sub> composite achieved a remarkable specific capacitance of 587.5 F g<sup>− 1</sup>, surpassing pristine BAC and Ni₃Co₆-LDH by 101.2% and 79.0%, respectively.

Furthermore, the quality of commercial agarwood is determined through subjective evaluation by human experts, and standard quality controls are lacking. In this study, we evaluated the effects of chemical injury treatments using plant hormones (salicylic acid, methyl jasmonate, and ethylene), which have attracted attention in the production of artificial agarwood. Resin-deposited areas on the treated branches were quantified using image analysis as an objective quality indicator. In addition, the yield of 2-(2-phenylethyl)chromones (2PECs), which are essential fragrance compounds in high-quality agarwood, was quantified. Treatment with salicylic acid or methyl jasmonate resulted in resin-deposited areas more than double those of the control, with enhanced 2PEC content, such as oxidoagarochromone A, B, and C, and agarotetrol. Additionally, treatment of wood with over-the-counter medicines containing salicylic acid resulted in a dramatic increase in the resin-deposited area and 2PEC content. Furthermore, the total oxidoagarochromone A, B, and C content was positively correlated with the resin-deposited area in the six months treatment samples. This is the first study to quantitatively demonstrate the effect of plant hormones on the agarwood resin-deposited area and 2PEC content, especially oxidoagarochromone A, B, and C, and agarotetrol, simultaneously, and is expected to contribute to further development of artificial agarwood production, quality evaluation methods, and elucidation of the resin deposition process.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"60 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146026910","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}

Heat-treated wood showed reduced dimensional changes in both radial and tangential directions, particularly in LW. The shrinking coefficient significantly decreased after heat treatment, while the swelling coefficient remained relatively stable. Desorption and absorption isotherms revealed reduced sorption hysteresis as well as swelling hysteresis, particularly above 10% moisture content.

Wood’s insulation performance can be enhanced by creating additional porosity through the removal of non-cellulosic substances. Although delignification techniques have been used in the pulping industry to produce cellulose pulp, they have evolved to produce cellulose nanofibers or cellulose scaffolds for functional materials. Various top-down delignification techniques have been suggested for solid wood, but most studies have focused on a single technique applied to a specific wood species, making it difficult to compare the effectiveness of different methods. This paper addresses this gap by presenting a comparative analysis of literature-established delignification techniques applied to solid wood pieces: soda pulping, alkaline sulfite pulping followed by hydrogen peroxide bleaching, and organosolv pulping followed by sodium chlorite bleaching. This study evaluated the impact of these techniques by examining the changes in mass loss, chemical constituents and FTIR spectra of French poplar wood planks of 100 cm<sup>3</sup> after treatment. The combination of organosolv pulping by alcoholysis and sodium chlorite bleaching was found to be the most effective method for complete lignin removal. Our findings reveal the strengths and limitations of these methods, providing insights into the selection of wood modification techniques for upscaling purposes. Further research on drying delignified wood is required to complete a preliminary study of the industrialization of insulating wood.

Yamamoto et al. (2022) proposed a hypothetical mechanism to explain the origin of HTR behavior in G-fibers, suggesting that two modes of denaturation of matrix components—namely, softening and degradation of non-crystalline polysaccharides in the G-layer—cause contractile recovery of the stretched cellulose microfibrils (CMFs). However, this mechanism remains qualitative and cannot quantitatively predict the complex HTR-strain behavior observed in G-fibers, such as the “initial recovery” and “continuous contraction” reported by Sujan et al. (2015). To address this limitation, the present study employed a numerical simulation approach based on a theoretical model. First, a mathematical rule was extracted from observed temperature- and time-dependent patterns of HTR-strain in the G-fibers. Second, the softening and degradation of non-crystalline polysaccharides in the G-layer matrix, as hypothesized by Yamamoto et al. (2022), were formulated within the framework of reaction kinetics. Third, by integrating this formulated mechanism with the extracted mathematical rule, a predictive model for HTR- behavior in G-fibers was developed. Finally, the newly developed model was used to quantitatively simulate experimental results. This model facilitates a rational elucidation of the microscopic mechanism of HTR in G-fibers by representing the dynamics of cell wall components and reproducing the macroscopic HTR-behavior observed in the G-fibers of TW.</p></div>","PeriodicalId":810,"journal":{"name":"Wood Science and Technology","volume":"60 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145730144","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}
