In order to understand the competitive situation of wood, it is essential to consider the end consumer of building materials. The knowledge of factors affecting the end consumer’s choice of building material f...
Influences of moisture content on the catalysis of sulfur dioxide and physical properties of reaction products were examined for a vapor-phase treatment of spruce wood with formaldehyde. The reaction rate was ...
The amount of apparently nonfreezing water per dry mass unit significantly differs between earlywood and latewood, and drying changes the nonfreezing water content of earlywood cell walls in a time-dependent m...
To improve the drying method in the manufacture of woodwind reeds, green canes (Arundo donax L.) were dried under various humidity–temperature conditions and the intensity of cell collapse was evaluated from the ...
