Freezing stress threatens the survival of trees by inducing the accumulation of ice bodies within wood tissues. However, accurately assessing ice content in wood tissues remains a challenge. This study aimed to develop a theoretical-empirical prediction model of frozen water content (FWC) to evaluate the quantity of ice forming in wood tissues. Differential scanning calorimetry was employed to examine the changes in FWC of pine (<i>Pinus koraiensis</i> Siebold & Zucc.) and poplar (<i>Populus simonii</i> Carr.) wood tissues under a series of subzero temperature points at two cooling rates. The corresponding responses of specific extracellular resistance(<i>r</i><sub>e</sub>) and intracellular resistance(<i>r</i><sub>i</sub>) were obtained by electrical impedance spectroscopy. Experimental study showed that FWC increased as temperature decreased, with a notable transition around − 40 °C. The corresponding <i>r</i><sub>e</sub> initially increased and then decreased, peaking at − 40 °C. The change trend of <i>r</i><sub>i</sub> was consistent, but reached its peak value at − 30 °C. In the temperature ranges of 0 to − 30 °C and below − 40 °C, the specific theoretical linear models between FWC and <i>r</i><sub>i</sub>, and the logistic model of FWC at a semi-lethal temperature zone of − 30 °C to − 40 °C were respectively established for both wood species. The theoretically predicted values fitted well with experimental values, with the prediction error below 5%, verifying the validity of the theoretical model.

The accuracy and reliability of this theoretical model are verified through actual measurements of the wave velocity conversion ratio in several different tree species, and the following conclusions were obtained: the theoretical wave velocity conversion ratios for the tested tree species are all greater than 1.1. Radiata pine and loblolly pine have the highest theoretical conversion ratios, both at 1.19, while western hemlock has the lowest value at 1.10. The theoretical conversion ratio for larch used in this study is similar to that of radiata pine and loblolly pine, at 1.18. Except for loblolly pine, the theoretical conversion ratios for the other species are all lower than those of larch and radiata pine. This may be due to differences in species or factors such as moisture content. Therefore, when calculating the theoretical wave velocity conversion ratio for a specific species in the future, it is best to use the elastic constant values for that particular species in its green condition. The measured wave velocity conversion ratio for ponderosa pine is the highest at 1.36, while red pine has the lowest at 1.10. The difference between the measured and theoretical wave velocity conversion ratios for radiata pine is the smallest, at only − 0.8%, while the largest difference is for ponderosa pine, at 22.5%.

To this purpose, various parameters (β–cyclodextrin ratio, temperature, PBB extract volume, and time) were optimized using Response Surface Methodology–Central Composite Design. The significant parameters and optimum conditions that influenced the response were identified. Under optimum conditions, the experimental encapsulation efficiency was 90.45 ± 1.34%, closely matching the predicted encapsulation efficiency of 93.31%.

Its radial structure, composed of distinct anatomical regions—such as the bamboo outer layer (BOL), inner layer (BIL), pith ring (BPR), and membrane (BM)—results in variations in chemical composition and contributes to complex moisture diffusion behavior. To explore how these regions contribute to moisture transport, three types of bamboo samples were prepared: intact (BOL/BM), BM removed (BOL/BPR), and both BM and BPR removed (BOL/BIL). Water vapor diffusion was assessed using the wet cup method (humidity levels of 85% and 0%). The work measured diffusion in both the outer-to-inner (BM-BOL, BPR-BOL, BIL-BOL) and inner-to-outer (BOL-BM, BOL-BPR, BOL-BIL) directions. The results indicated that the moisture diffusion was significantly more efficient in the inner-to-outer direction compared to the outer-to-inner direction. BOL-BIL showed the lowest water vapor resistance factor (<i>µ</i> = 62.73 ± 1.55), attributed to the exposure of parenchyma cells and vessels following BPR removal. Conversely, BOL-BPR showed the highest resistance (<i>µ</i> = 108.96 ± 4.93) due to the high lignin content and thick-walled cell structure of BPR. The BM’s layered and porous architecture, formed by collapsed pith cells, facilitated efficient moisture diffusion, endowing it with optimal hygroscopic properties. However, BPR’s inhibitory effect increased resistance in BOL-BM (<i>µ</i> = 81.17 ± 2.43).

For simulations, an innovative simplified moso bamboo model comprising three primary components (cellulose, hemicellulose, and lignin) was constructed by the Materials Studio software. The LIG formation process was simulated at the atomic scale using LAMMPS software with the ReaxFF reactive force field to elucidate the underlying mechanism. During experiments, the multiple characterization techniques were employed to analyze the microstructure, elemental composition, structural features, crystalline phases and defect structure of the LIG.

The results indicated that BCNF exhibited superior performance compared to LCNF in improving the mechanical properties of the epoxy composites. Specifically, a 0.75% BCNF loading significantly enhanced the composite’s toughness (41% increase) and elastic modulus (79% increase) while reducing brittleness, making the material stronger and more ductile. In contrast, LCNF composites displayed lower mechanical performance and reduced ductility. The interaction between BCNF and the epoxy matrix was more pronounced, as confirmed by QCM-D and FTIR analysis, suggesting better compatibility. Thermal analysis showed that both BCNF and LCNF reduced the thermal stability of the epoxy matrix, but LCNF, with lignin, provided some protection. Lignin’s aromatic and antioxidant structure helped maintain thermal resistance, making LCNF composites at 1% loading thermally comparable to neat epoxy.

To address this limitation, this study introduces a novel approach utilizing delignified biomass from branch (BH) and bark (BK) along with SW in combination with polyvinyl alcohol (PVA), a biodegradable and eco-friendly polymer matrix. The delignification process effectively removed the lignin, leading to enhanced cellulose crystallinity, increased optical transmittance, and improved polymer infiltration.

In contrast, transparent composites made from stem wood (TSWs) exhibited the highest mechanical strength, which was attributed to their densely packed fiber structure and high cellulose content, making them more suitable for load-bearing applications.
