Non Technical Summary
Comprehend key chemical and structural aspects of the cell wall so that forest products utilization can be increased and improved for traditional and non-traditional uses. The overall goal is to establish a better understanding of the chemistry of the cell wall and how the cell wall polymers are spatially arranged with respect to each other at the molecular level, as well as the nanoscale level.

Objectives Summary
The focus of this problem is to bridge the fundamental understanding of wood cell wall chemistry, biology, and mechanics with novel and applied technologies involving wood cell walls. The fundamental aspects of the cell wall that we learn will be a foundation on which all developed technologies can be built upon. Aspects will include research surrounding cell wall ultrastructure and architecture on a micron-scale, nano-scale, and Ångstrom-scale. The components of this area include: (1) characterizing cell wall polymers in native wood and modified wood; (2) establishing more accurate wood cell wall models; (3) understanding structure-property relationships via water/solvent/component inter-diffusion and infiltration in the matrix; (4) improving the cell wall properties (physical, mechanical, biological degradation, fire resistance, etc.); (5) utilizing cell wall polymers from trees and plants for bio-resins and bio-energy.

Approach Summary
Widely varied.
