Accelerated aging treatments are often much more severe than necessary for final panel products that are being installed. It is thought that tests under these conditions are unable to exhibit properly the degr...
Since computed tomography (CT) X-ray scanning is becoming a reality in sawmills, different studies have been made to establish how well the sawing position of a log can be optimized using CT data. It is also k...
Load and moisture content (MC) changes are the essential conditions for the mechano-sorptive (MS) creep of wood. An experiment was carried out on poplar to comprehend the mechano-sorptive creep from our point ...
Jatropha curcas L. has been cultivated in many countries for biodiesel production, and defatted kernel is generated in huge quantities as a by-product in the production. This study invest...
To evaluate the drag coefficients for roof-top tree crowns, previously developed field test methods for monitoring wind speed, wind direction, and stem deflection were improved using solar cells as a source of...
The 1–3-year-old bamboo (Phyllostachys puberscence) culms were exposed to ambient weathering conditions for 12 months. Changes in color, surface topography, and chemical features of bamboo culms by weathering wer...
The mechanism of differentiation of tracheid (earlywood or latewood) should be elucidated to improve the wood properties of sugi trees (Cryptomeria japonica). Water deficit affects tracheid differentiation in con...
In the present study, colour changes in black alder (Alnus glutinosa L. Gaertn.) and beech (Fagus sylvatica L.) wood veneers subjected to heat treatment at 190 °C for different time spans were investigated. The p...
Knowledge of the thermal conductive properties of wood at low temperatures aids the development and optimization of the application of a lethal cold temperature treatment for drywood termites. The present stud...
The tool material and the parameters of machining are the main conditions which decide the quality of particleboard surface. The objective of the study was to investigate the wear of a carbide cemented bit and...
5-Hydroxymethylfurfural (5-HMF) is one of the most important platform intermediates for the future synthesis of liquid transportation biofuel and other valuable compounds. This study aimed to identify ionic li...
As a follow-up report, the pre-treatment by compression for wood drying was systematically studied in terms of effects of compression ratio, compression direction and compression speed on the recovery rate (RR...
Cutting of wood using short-wavelength (266-, 355-, 532-, and 1064-nm) lasers was carried out and wavelength dependence in relation to machining performance and post-processing appearance was investigated. We ...
6-O-[Acetylacetonato-bis(2,2′-bipyridine)ruthenium(II)]-2,3-di-O-myristyl cellulose (3) was prepared from 2,3-di-O-myristyl cellulose (1) by two reaction steps in 37.7 % total yield. The LB monolayer film of comp...
Friction between metal tools and wood under high pressure (≥1 MPa) necessarily arises during wood deformation processes and is thus an important factor to be taken into account when wood is processed. We focus...
This paper presents a study on rolling shear damage accumulation and duration of load of cross-laminated timber (CLT) with low cycle fatigue tests. The study of the duration-of-load (DOL) effect on strength p...
