This study focuses on enhancing the properties by impregnating poplar wood with polyvinyl acetate (PVAc) resin fortified with nano hexagonal boron nitride (h-BN). The vacuum-pressure impregnation process was followed for treatment and the treated samples were evaluated for fungal decay resistance against brown rot and white rot fungi, as well as density, water absorption, surface hardness, compressive strength and thermal stability. Nanoparticles distribution within the wood microstructure was analysed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) mapping. Results showed that h-BN fortification of PVAc with different concentrations further improved the properties of poplar wood.

In total 2457 specimens were tested in mechanical strength and around 1000 for dimensions of micro and macrostructural wood elements. In the case of the most important parameter – the wood density, no significant differences were found between values observed in standard forest land (0.722 g/cm³) and afforested farmland (0.701 g/cm³). Land use did not significantly influence MOR nor MOE. However, higher values for these parameters were observed on forest land. The annual ring width was significantly wider on trees that grew on former agricultural land. The high variability with significant differences was obtained within the dimensions of vessels and fibers. The presented results have confirmed that European beech species is highly suitable for former agricultural land afforestation with high-quality wood production.

Willow (<i>Salix</i> sp.), a short-rotation hardwood species, is an interesting feedstock for such applications. It can represent an alternative raw material for non-sustainable resources, long-rotation trees, and agricultural biological materials. This research aimed to characterize the chemical properties of different wood tissues of willow and to develop a nondestructive method for their prediction. Wood, bark, and twig samples were sampled from six willow clones (Alberta, Canada). Extractives, cellulose, hemicellulose, and lignin contents were measured in sampled tissues by destructive chemical analysis tests using TAPPI standard test methods. The surface chemistry of the samples was analyzed by near-infrared spectroscopy. Partial least squares regression models were developed for quantitatively predicting wood chemical components. The coefficients of determination (R² calibration, R² cross-validation, and R² prediction) ranged from 0.66 to 0.99 for extractives, lignin, cellulose, and hemicelluloses. Carbohydrates (glucose, xylose, arabinose, and mannose) ranged between 0.98 and 0.99, demonstrating excellent predictive capability for these components. These results confirm the applicability of the developed models to predict the chemical properties of willow biomass. Furthermore, the prediction models apply to all investigated tissues, emphasizing consistency. These results provide the possibility to characterize the chemical properties of willow biomass using easily implemented, cost-effective, nondestructive, and rapid NIR equipment.</p></div>","PeriodicalId":550,"journal":{"name":"European Journal of Wood and Wood Products","volume":"83 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145028286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MW_400 treatment significantly improved wood impregnability, enabling 70% higher preservative uptake while maintaining low leaching (4%). The results indicated that MW_400 samples were more stable dimensionally than MW_700, which may be related to the reduction in hemicellulose (12%) and rise in lignin content (22%) of MW_400 samples. The synergistic effect of MW_400 combined with preservative treatment resulted in the highest biological resistance, with reductions in fungal mass loss of up to 54.4%, thereby classifying the wood as resistant.

MW treatment did not increase the wood’s brittleness. Overall, the MW_400 treatment demonstrated superior performance compared to MW_700, particularly when combined with preservative impregnation, resulting in improvements in dimensional stability and durability while preserving mechanical integrity.

Enhancing its water resistance is critical for broadening its applications, especially in humid and outdoor environments. This study investigates the enhancement of MDF water resistance through the chemical modification of the constituent wood fibres (in this case, thermo-mechanical pulp or TMP) through periodate oxidation. The treatment with sodium metaperiodate results in the formation of dialdehyde fibres (DA-TMP) which are then spray-coated with a phenol-formaldehyde resin, following the industrial procedures, and converted into a MDF through proper hot pressing. Comprehensive evaluation of the physical, mechanical, and biological properties is conducted, along with the study of fire behaviour comparing boards made from both oxidized and non-oxidized fibres. The results reveal that periodate oxidation reduces water absorption by 54% and thickness swelling by 56%, indicating significant changes in the fibres’ chemistry and morphology. Despite a slight decrease in mechanical properties, the overall performance of DA-TMP based MDF confirms this as a promising method for achieving superior durability in moisture-prone environments, including outdoor constructions. Importantly, the biological resistance of the material remains unaffected by the oxidation of the fibres, ensuring continued protection against biological attack and long-term durability. Additionally, fire performance tests show that DA-TMP based MDF exhibit reduced peak heat release and smoke production, further enhancing their suitability for fire-sensitive applications. Consequently, this research contributes to expand the use and durability of wood-based materials across various industrial sectors, offering a sustainable and effective alternative to traditional moisture resistance treatments.</p></div>","PeriodicalId":550,"journal":{"name":"European Journal of Wood and Wood Products","volume":"83 5","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00107-025-02325-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the impact of secondary fibres, generated from recycling of both processing and post-consumer waste, on the properties of new MDF panels. The fibres were recycled using a modified thermo-mechanical pulping (mTMP) and steam treatment (ST) processes. Virgin pine and secondary fibres were studied for their size distributions and morphological features. MDF panels were fabricated by substituting virgin fibres with secondary fibres at 15% and 25% rates, with additional 100% recycled MDF produced using ST-obtained fibres. Secondary fibres from both waste sources were shorter and had more fines than virgin fibres. For recycled MDF incorporating ST fibres, a notable drop in internal bond strength was observed when using fibres from post-consumer fibreboard waste, while modulus of rupture, modulus of elasticity, thickness swelling, and water absorption remained consistent. Increasing substitution rates from 15 to 25% resulted in an insignificant change in the aforementioned physical and mechanical properties. However, MDF produced with 100% recycled fibres exhibited a dramatic decrease in physical and mechanical properties, despite a reduction in formaldehyde content. Compared to MDF with virgin fibres, the internal bond strength of recycled MDF statistically decreased at all substitution ratios. In contrast, other properties were comparable at 15% or 25% rates for fibres produced using the mTMP process.
