Non Technical Summary
As a building material, wood fails because it gets wet. Wood exhibits swelling upon moisture uptake and shrinkage upon drying, and these cyclical moisture changes lead to internal stresses and can eventually form splits and checks within the wood. When there is an abundance of moisture in the wood, it is susceptible to microbial growth, fungal decay, corrosion of embedded metals, and chemical depolymerization from certain ions and free radicals. This problem area performs fundamental research on how and why wood gets wet so that new strategies for wood protection can be developed.


Objectives Summary
The objective of this problem area is to conduct fundamental research on heat and mass transfer in wood so that a mechanistic, physical understanding can be used to develop new methods of making wood more durable and fire resistant.


Approach Summary
This objective requires the development of new, unconventional research techniques. Since water affects wood at multiple length scales (from 10 superscript -9 m to 10 superscript 1 m), the research needs to be conducted across multiple length scales as well as research aimed at understanding the relationship between the length scales.
