Supercritical carbon dioxide treatment: Effect on permeability of Douglas-fir heartwood

Creator:

Demessie, Endalkachew Sahle, Hassan, Ali, Levien, Keith L., Kumar, Satish, and Morrell, Jeffrey J.

Abstract:

The effect of supercritical fluid treatment on superficial gas permeability of Douglas-fir was investigated by using carbon dioxide either alone or amended with methanol. Permeability increased in a majority of samples, although nearly one-third of the specimens declined in permeability. Improvements in permeability appeared to be unrelated to variations in...

Assessing Fungal Decay of Wood by Small-scale Toughness Tests

Creator:

Sexton, Camille M., Corden, Malcolm E., and Morrell, Jeffrey J.

Abstract:

Impact bending and breaking radius were used to measure loss in toughness caused by basidiomycetes isolated from wood. Small test pieces were used to accelerate testing. Wide differences were found among, and sometimes within, the 26 species tested. Brown-rot fungi tended to cause greater losses than white-rot fungi, but no...
