... The hydrophobicity of most wooden materials is observed only on their surfaces, and when the internal structure is exposed, the hydrophobic effect weakens or even disappears. Therefore, the development of construction schemes that consider superhydrophobic properties on the surface and in the internal structure of wood has gained importance [86]. The hydrothermal method creates a high-temperature and high-pressure environment using an aqueous solution as the reaction medium. ...

... Far-infrared paper, with its excellent far-infrared emission properties, can emit far-infrared electromagnetic waves of specific wavelengths when attached to the wood surface. These far-infrared waves promote ion migration and charge distribution within the wood, thereby enhancing its conductivity (Shi et al. 2025). This synergistic effect enables the wood to exhibit higher current and voltage during hygroscopic electricity generation, thus significantly improving its energy conversion efficiency. ...

... The bands at 1509 and 1596 cm −1 (aromatic skeletal vibrations) and at 808 cm −1 (C-H out-of-plane aromatic in lignin) completely disappeared. A decrease in the intensity of the absorption bands can also be observed in the region 1485-1440 cm −1 (overlapping bands of C-H deformation vibrations in lignin and polysaccharides) and 1300-1185 cm−1 (C aryl -O, guaiacyl ring breathing with CO stretching at 1264 cm −1, and C-O linkage in guaiacyl aromatic methoxyl groups and acetyl groups in xyloglucan at 1230 cm −1 ) [74,75]. These findings are consistent with Hoffman et al. [76] and Godinho et al. [77], indicating that thermal modification does not contribute to lignin protection. ...

... This phenomenon is due to the enhanced electrolyte movement under high current density, which does not react with Co(OH) 2 in time, resulting in a significant reduction in the pseudocapacitance ratio. This observation is consistent with most of the current findings [39,40]. The corresponding specific capacitance is shown in Fig. 9c. Figure 9d shows the CV curves of 3C/ HG@BE-Co-1500 as the scan rate increases from 2 mV/s to 50 mV/s. ...

... The interface modification mechanism of the SCA on the concrete with excessive mica is illustrated in Figure 15. The SCA first undergoes the hydrolysis reaction by mixing water and dehydration condensation to form the silane oligomers [69]. Then, the hydroxyl group in the silane oligomers forms hydrogen bonds with the hydroxyl groups on the surface of the mica or C-S-H gel, thereby forming a bridging structure in the mica or hydration products [47,70]. ...

... It is usually used as raw material for wood-based panel such as fiberboard, particleboard, plywood and other wood-based board, indirectly used in household and other fields, or as raw materials for papermaking and building templates [4]. Although domestic and foreign scholars have developed corresponding processing and technologies to modify and functionalize the fast-growing wood such as recombination [5][6][7], consolidation, softening, plasticization, color treatment [8,9], anti-corrosion [10], and flame retardant [11,12], so as to broaden the application field of fast-growing wood. With the increasing pursuit of sustainable architecture, wooden structures are widely favored due to their environmental characteristics and the utilization of renewable resources. ...

... Teakwood components submitted to synergistic treatment with softening solution and saturated steam impregnation can obtain excellent bending properties [1,2], but even after molding, these components have a strong shape memory effect due to their high moisture content [3,4]. When wood's cell walls are saturated with moisture and have intense internal thermal movement, and an external bending force is removed, the bending components may demonstrate rapid spring-back [5]. ...
