Bark samples of two particle sizes were stored either outdoors (exposed to precipitation) or indoors (dry, dark conditions). The extracts were analyzed monthly by gravimetry and UV-Vis spectrophotometry. The results showed that both particle size and storage conditions significantly influenced the retention of extractives and polyphenols in the samples. The highest losses occurred in ground bark samples stored outdoors, while the best retention was achieved with larger bark particles stored in a covered, dry environment.

AC was incorporated into the urea–formaldehyde (UF) adhesive at 0.5–1.5% by weight and applied to both surface and core chips, ensuring its distribution across all three layers of the particleboard.

Mechanical test results of particleboard indicate that the inclusion of 1.5% AC increased MOR by 26% (from 10.02 N/mm² to 12.65 N/mm²) and MOE by 52% (from 1083.83 N/mm² to 1645.33 N/mm²), while IB rose from 0.41 N/mm² to 0.53 N/mm². Additionally, formaldehyde emissions of particleboard decreased significantly from 11.25 mg/100 g (control) to 8.01 mg/100 g at production (0th month) and further to 3.20 mg/100 g after 12 months.

The present article addresses the experimental assessment of the mechanical and bonding performance of glulam beams made by European beech (<i>Fagus sylvatica</i> L.) from Spain. A total of 48 glulam beams (homogeneous and combined) have been produced at the laboratory facilities (20 without finger joints and 28 with finger joints).

For the prediction of the mechanical properties (modulus of elasticity), the Transformed Section Method and Longitudinal Vibration Method were considered. Correlation coefficients of 0.90 or higher have been obtained. Additionally, 41 lamellas with finger joints have been characterized by tension, resulting in a characteristic tensile value of 50.8 MPa. Its influence on the bending properties of the glulam beams has been evaluated, obtaining a characteristic bending strength value of 52.9 MPa.

Wood, a naturally abundant and lingocellulosic material, exhibits sound absorption properties influenced by its porosity, gas permeability, and structural integrity. This study aimed to investigate the relationship between these properties and the sound absorption coefficient (SAC) of five wood types: Coconut (<i>Cocos nucifera L.</i>), Hackberry (<i>Carya ovata</i>), Malas (<i>Homalium foetidum Roxb</i>.), Oak (<i>Quercus mongolica</i> Fisch.), and Paulownia (<i>Paulownia tomentosa</i>). Using the two-microphone transfer function method, SAC was measured across a frequency range of 250–4000 Hz, both with and without back air cavities (0–4 cm). Additional analyses included porosity determination via helium pycnometer, gas permeability using a capillary flow porometer, and surface morphology assessment with a 3D optical profilometer. Results showed that back air cavities significantly enhanced low-frequency SAC. Hackberry and Oak achieved the highest Noise Reduction Coefficients (NRC) values (0.55 and 0.53, respectively at a 4 cm cavity depth). Porosity was critical for low-frequency absorption in Coconut (80.91%) and Paulownia (55.56%), while high permeability and large pore sizes favored low-frequency performance in Oak and Hackberry. Malas demonstrated balanced acoustic properties across frequencies due to its intermediate porosity and diffuse pore structure. This research highlights the novelty of correlating wood anatomy with acoustic behavior and optimizing back air cavity depth to tailor performance.

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.
