The effects of tree position and silvicultural practices on treatability of Douglas-fir lumber

Creator:: Hong, Seungdo
Abstract:: In spite of the lack of accurate information about the treatability of western wood species with waterborne wood preservatives, consumption of these products continues to increase. Western wood species, notably Douglas-fir, are notoriously difficult to treat with waterborne systems, yet there is relatively little data on the effects of wood...

Essential oil treatment of VTC wood

Creator:: Scouse, Adam A.
Abstract:: Western juniper and cinnamon essential oils were combined with ethanol at 2.5, 5, and 10% concentrations by weight and applied to hybrid poplar (Populus trichocarpa x P. deltoids) veneers by vacuum soaking to produce a naturally durable wood veneer with increased mechanical properties for use in structural composites. Half of...

Characterization of Fungal Communities in Selected Wood Species by Field Exposure Tests

Creator:: Torres-Andrade, Paola A.
Abstract:: Fungi are the primary biological agents of wood deterioration and cause major economic losses of wood products globally. Wood in outdoor applications tends to remain wet for extended time periods, making it susceptible to fungal attack. Understanding the factors involved in fungal colonization of wood is important for developing improved...

Natural durability of wood : a worldwide checklist of species

Creator:: Scheffer, T. C., Morrell, Jeffrey J., and Oregon State University. Forest Research Laboratory
Abstract:: Naturally durable woods have a variety of commercial uses. Natural resistance to decay has been evaluated in field and laboratory tests of wood from many species, but there are few places where commercial wood users can find comparative assessments of natural durability. In this report, previous studies have been used...

Controlling biodeterioration of western wood species with over- the-counter wood preservatives

Creator:: Newbill, Mark A.
Abstract:: Over-the-counter (OTC) wood preservatives can provide wood with both a moisture barrier and fungicidal protection against biodeterioration, yet there is little comparative data on the performance of these preservatives. In this study, the potential of various low-toxicity, OTC preservatives was evaluated on five western wood species, western red cedar (Thuja...

The effects of supercritical CO₂ on the bending properties and treatment defects of four refractory wood species

Creator:: Anderson, Matthew E.
Abstract:: It is difficult to treat the heartwood of many wood species with liquid preservatives using conventional liquid processes. Supercritical fluids (SCF) used as carriers of preservatives to impregnate refractory wood species may be an attractive alternative to conventional liquid carriers. While SCF impregnation has many potential advantages, some wood species...
