Summary: Providing the equilibrium moisture content values is crucial for avoiding issues in wooden products caused by dimensional changes. This study determined the average equilibrium moisture content values for twelve months in Laos and created a map illustrating these values. By utilizing temperature and relative humidity data, a model was used to generate the equilibrium moisture content values for 18 provinces (148 districts) in Laos based on their geographic coordinates. The results showed that Vientiane Capital City and Champasak province had the lowest equilibrium moisture content values (12% to 13%), while the rest of the districts mostly fell within the range of 13% to 16%. The monthly average equilibrium moisture content values varied from 10% to 18% across the country.

Summary: A terahertz time-domain spectroscopy system was utilized to monitor the crystallinity and moisture content of PET specimens. The crystallinity and moisture content were controlled by adjusting the cooling rate and immersion time. The crystallinity, crystallite size, and moisture content of the PET specimens were determined using DSC, XRD, and gravimetric methods respectively. The THz signals were analyzed in the time and frequency-domain to evaluate the crystallinity and moisture content, and the optical parameters such as refractive index and absorption coefficient were also obtained. Therefore, the THz signals can be employed to measure the crystallinity and moisture content simultaneously.

Summary: This study investigates the effect of surface free energy and pore volume on the moisture resistance of sol-gel silica coatings, and finds that both factors independently and synergistically affect moisture resistance. As the surface free energy and pore volume decrease, the moisture resistance improves. Once the surface free energy reaches a certain value, the moisture resistance becomes superior, regardless of the microstructure of the coatings. Similarly, once the pore volume of the coatings reaches a certain value, notable moisture resistance is observed, regardless of the surface chemical composition.

Summary: This study tested the compression properties of natural bamboo and observed the crush morphologies under different moisture contents and fibrous structures. The results showed that dry bamboo had higher compression strength with shearing as the predominant failure mode, while wet bamboo demonstrated delamination and splitting. Acoustic emission and fracture morphology indicated five compression behavior categories. Bamboo node samples exhibited heightened compressive strength and modulus due to their coarser 3D fibrous structures.

Summary: This study focuses on the in-plane shear behavior of carbon fiber-reinforced polyamide 6 cross-ply laminates. Bias-extension tests are conducted at different temperatures and deformation rates to compare forming behavior with the prediction of the pin-jointed net (PJN) idealization and investigate the effects of temperature and deformation rate. The results show that the shear behavior is comparable to woven fabrics, with the PJN holding up to a shear angle of 30 degrees. The locking angle of the material is estimated to be 45 degrees, and after locking, significant fiber slippage and compaction occur.

Summary: In this study, we investigate the temporary network topology and elasticity of micellar networks formed by hydrophobically associating multiblock copolymers. By using a combinatorics approach, we extend the mechano-statistical transient network model to multiblock copolymers and show that the micellar network microstructure can predict the concentration dependent elasticity. The network transitions from loop-dominated, poorly elastic structures with low functional cross-linking nodes at low concentrations to bridge-dominated, highly elastic structures with higher functional nodes at elevated concentrations.

Summary: This study reveals the mechanism of catalyst poisoning by organic sulfur species in commercial 5-HMF feedstock during its hydroconversion. Various sulfur species were found to have a significant catalyst poisoning effect on HMF hydroconversion. The degree of poisoning is correlated with the thermodynamic favorability of metal sulfide formation. The presence of reduced sulfur species was identified as the ultimate metal poisoning agent, and their formation from more oxidized sulfur compounds explains the observed poisoning effect.

Summary: In conventional bifunctional catalysts, metal sites are responsible for catalytic activity, while acid sites are typically located on oxide supports. This study investigates the modification of metal sites with halogens to generate acidity through the heterolytic dissociation of hydrogen. High-throughput screening of different combinations of metals (Co, Ni, Ru, Pt, Pd, Rh) and halogens (Cl, Br, I) reveals that only Pd and Pt catalysts can form acid sites through interaction with Br, Cl, and I. Characterization and density functional theory (DFT) modeling suggest that hydrogen undergoes heterolytic dissociation over halogens located at the edges and corners of Pd and Pt nanoparticles, with the strength of the acid sites increasing with the electronegativity of the halogen.

Summary: In this study, a thermoresponsive and biocompatible hydrogel composed of poly(N-isopropylacrylamide) (PNIPAAm) and cellulose nanocrystals (CNC) was developed. The hydrogel was generated through simple mixing without complicated derivatization, and its composition was optimized to enhance its stiffness. The hydrogel showed good compatibility with fibroblast cells and its thermoresponsive characteristics were observed. The findings suggest that this PNIPAAm-CNC hydrogel can be used as a versatile and affordable material for controllable 3D cell culture and may have potential applications in 3D-printing.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
