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...
