Electrical resistivity of wood–cement biocomposites of Pinus pseudostrobus
Abstract This study investigates the influence of incorporating 5% gray and white Portland cement on the electrical resistivity of wood–cement biocomposites manufactured from Pinus pseudostrobus sawdust and a wheat-protein adhesive. Three composite formulations were prepared: a control (no cement)…

Simultaneous confocal laser scanning microscopy (CLSM) observation of melamine–urea–formaldehyde resin and pMDI wood adhesives penetrating plywood
Abstract Wood absorbs carbon dioxide from the atmosphere, and by being converted into wood-based materials, stores carbon in the long term, thereby contributing to the mitigation of global warming. Wood production relies on adhesives, making a detailed understanding of the adhesive interface…

Machine learning-driven research in wood science: from prediction to understanding through the framework of Wood Informatics
Abstract Machine learning (ML) has rapidly expanded across wood science, enabling data-driven approaches for the characterization, performance evaluation, and process optimization of wood and wood-based materials. Although these approaches have demonstrated remarkable predictive accuracy, the field…

Quantitative evaluation of unique residual stress observed in Japanese zelkova (Zelkova serrata) trunk
Abstract This study proposed a method to quantify the unique patterns of longitudinal residual stress in large-diameter Japanese zelkova (Zelkova serrata) logs and evaluated their characteristics using 11 logs from 8 trees. While the lateral distributions of longitudinal residual stress show the…

Experimental study on seismic performance of the original and reinforced inclined dougong-fork column in the Yingxian Wood Pagoda
Abstract Ancient wooden architecture serves as invaluable repositories of historical and cultural heritage. Among their critical components, the dougong-fork column plays a pivotal role, yet it is susceptible to inclination or collapse resulting from material degradation and external load actions…

Evaluation of stem diameter, Pilodyn penetration, and stress-wave velocity of stem in almost 320 clones of the first-generation plus trees of Chamaecyparis obtusa selected from the Kanto breeding region
Abstract Tree breeding programs in Japan have aimed to improve both growth and wood quality traits in Chamaecyparis obtusa. To enhance breeding for wood quality, it is essential to understand the genetic variability of traits related to growth, wood density, and stiffness. In the present study, we…

Chemical composition of thermally modified Eucalyptus grandis and Tectona grandis short rotation wood in closed system
Abstract This study investigated the chemical composition of short-rotation Eucalyptus grandis (eucalypt) and Tectona grandis (teak) wood subjected to thermal modification in closed system. Four treatments were evaluated: untreated eucalypt wood (EW), thermally modified eucalypt wood (TMEW)…

Wood spectral variability in Entandrophragma cylindricum across northern Congo: limited association with genetic structure despite high genetic diversity
Abstract Wood plays a crucial role in the economies of Central African countries, yet knowledge of the ecological and genetic determinants of intraspecific wood quality variation remains limited. In this study, we combined microsatellite-based population genetic analyses with short-wave…

Physiological and psychological relaxation effects from palmar contact with a wooden conference table: a randomized crossover study in an office conference room
Abstract The effects of palmar contact with wood on human physiology have been investigated in laboratory settings, whereas evidence from experiments conducted in actual office conference rooms remains limited. We performed a within-subject crossover study evaluating physiological and psychological…

Preparation and evaluation of antibacterial activity of Ag+ supported modified Japanese cedar biomass
Abstract A novel antibacterial agent was synthesized from Japanese cedar sawdust, a representative woody biomass resource, through chemical modification using potassium permanganate. The oxidation treatment introduced carboxyl groups onto the biomass surface, providing active sites for Ag+…

Linkage-dependent terminal localization of p-hydroxyphenyl-containing substructures in Cryptomeria japonica compression wood lignin
Abstract Lignin is a major aromatic polymer in plant cell walls and contributes to mechanical strength, hydrophobicity, and resistance to microbial degradation. In softwoods, compression wood formed in response to gravitational stimuli contains lignin enriched in p-hydroxyphenyl (H) units, but how…

Optimization of timber design values via reliability analysis considering the load ratio and resistance factor
Abstract The aim of this study was to investigate the relationship between the reliability index (β) and the resistance factor (∅) of structural timber to establish appropriate design values under the load and resistance factor design (LRFD) framework. Specifically, β is evaluated according to the…

Effect of biomass compression on the fiber characteristics and bending properties of medium-density fiberboard from oil palm residues
Abstract To address the declining availability of rubberwood in Southeast Asia, we explored the use of oil palm residues—oil palm trunk (OPT), frond (OPF), and empty fruit bunch (EFB)—as alternative raw materials for the production of medium-density fiberboard (MDF). In particular, we focused on…

Investigation of the effect of orientations and different side arrangements of glued flattened-densified bamboo panels on physical and mechanical properties
Abstract Due to the increasing interest in bamboo as a construction material, addressing its geometric variation along the culm and the gradient fiber distribution across the wall thickness is essential to develop standardized products for large-scale use. One option is the flattening–densification…

Threaded sleeve bonded anchorage for carbon fiber reinforced polymer tendons in glulam beams: experimental testing and parametric simulations
Abstract Using prestressed carbon fiber reinforced polymer (CFRP) tendons to strengthen glulam beams is a promising approach to improve their load-carrying capacity and crack resistance. Reliable anchorage is critical for ensuring the overall performance of the beam. In this paper, a threaded…

Importance-driven bottleneck model: a multi-stage deep learning approach for analyzing swelling–shrinkage behavior of wood species and their mechanical properties
Abstract Experimental data were collected from defect-free specimens of 57 wood species in Central Europe, encompassing their structural, physical, chemical characteristics, and mechanical properties. The dataset highlights the complex relationships between physical properties (shrinkage–swelling…

Kraft lignin/aromatic compound-induced promoters in white rot fungus Gelatoporia subvermispora
Abstract White rot fungi are the only organisms that can completely degrade lignin in the plant cell walls. However, the regulatory mechanisms controlling the expression of lignin-modifying enzyme (LME) genes are still obscure. In this study, we investigated the expression of LME genes in the…

Model for damage evolution through dynamic stiffness degradation in three wood species subjected to very high cycle fatigue
Abstract The main objective of this research project is to characterize the evolution of fatigue damage produced by a flexural excitation device in three types of wooden beams of different species, namely Pinus pseudostrobus, Quercus scytophylla, and Cedrela odorata. A stiffness degradation model…
