Summary: This study investigates the application possibility of non-modified nanocellulose and nanocellulose functionalized with APTES as a formaldehyde scavenger in UF adhesive. The results show that functionalization significantly reduces the formaldehyde content in the adhesive. Although nanocellulose reinforcement improves the mechanical properties of the boards, silanization has no effect. However, functionalization with APTES contributes to a decrease in formaldehyde emission from the boards.

Summary: This study investigated the effect of nanofibrillated cellulose (NFC) and titanium dioxide (TiO2) addition in urea-formaldehyde resin formulation on the physical, mechanical, and morphological properties of particleboard samples. NFC (0.5% and 1%) and TiO2 (0.5%, 1%, and 2%) were added to a 10% adhesive formulation, and samples were produced under different pressure times (4 and 8 min). Water absorption, thickness swelling, internal bonding strength, modulus of rupture, modulus of elasticity, scanning electron microscopy, and statistical analysis were performed. The thickness swelling values ranged from 19.9% to 34.9%, and water absorption values were from 74.50% to 110.6%. The maximum values for MOR, MOE, and IB were 22.2 MPa, 2570 MPa, and 1.1 MPa, respectively.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
