in this study, the effect of soluble chitosan, thyme oil and linseed oil on the mold resistance of wood and its surface properties was investigated. both low and medium molecular weight chitosan with concentration of 1 and 2% were used. cypress wood samples with dimensions of 20 × 20 × 70 mm and moisture content of 12% were saturated by the preservatives. the results showed that the maximum abs...

Although paramagnetic contrast agents have an established track record in medical uses of magnetic resonance imaging (MRI), only recently has a contrast agent been used for enhancing MRI images of solid wood specimens. Expanding on this concept, wood veneers were treated with a gadolinium-based contrast agent and used in a model system comprising three-ply plywood panels fabricated from two unt...

CCA has been banned for residential use as a wood preservative in North America by the end of 2003. The alternatives will be copper-based chemicals, such as Ammonium Copper Quat (ACQ) or Copper Azole (CA). Leaching of copper from treated wood to environment will become one of the most important issues for the wood preserving industry. So far, no wood treatment with the new copper alternatives o...

In in vitro ruminal fermentation, micronised wood powder is digested to produce volatile fatty acids, but its fermentability is weak. The aim of the present study was to ascertain a suitable pretreatment of micronised wood powder to enhance volatile fatty acid production in vitro. Rumen fluid taken from beef cattle was anaerobically incubated with micronised wood powder. Initially, effects of p...
