Non Technical Summary
The nanotechnologies and nano-materials developed at FPL under this problem have a high probability for success and for use by industry. The expected gains of the research will be to improve existing products and processes. Nanotechnology and processing techniques will enable industry to develop wood products that are more competitive with other building products. Products include new wood-based products having improved dimensional stability, adhesive qualities, fire, decay, and termite resistance with treatments that are environmentally safe to produce, use, and dispose of. Nanotechnology will aid in the conversion of low value forest residues, fire and insect destroyed stands to value-added forest materials and feedstocks.

Objectives Summary
Using nanotechnology concept and methods, researchers will investigate the intrinsic properties of lignocellulosic materials and the influence of modifications of wood polymer components at the molecular, nano, and cell wall dimensions. With this in mind, there are five focus areas that need to be developed. 1) Develop fundamental knowledge of nano-scale phenomena and processes and elucidate scientific and engineering principles and mechanisms governing these phenomena and processes. 2) Develop comprehensive understanding of how changes at the nano-scale modify the physical, chemical, and biological properties at the micro and macroscopic dimensions. 3) Develop new generation of instruments to measure materials properties at the nano-scale. 4) Develop methods for synthesis, structure evaluation, materials and systems design. 5) Develop standards for testing, manufacture, and characterization of nano-materials.

Approach Summary
Investigating lignocellulosic materials at the nano-scale requires a comprehensive assessment in the types of analysis techniques that will be necessary to measure the desired property, feature, characteristic, or interaction. The use of conventional or established testing techniques and equipment will continue to be central to our research efforts; however, new testing techniques need to be developed so that lignocellulosic materials can be evaluated in innovative ways, thus providing a new perspective in the characterization of lignocellulosic materials. Likewise, it will be necessary to develop new equipment or modify equipment on the basis of advances in nanotechnology from other industries. There will be four focus areas for technique & equipment development: Nano-scale sensors, Nano-scale processing and process control, Analytical methods for nanostructure characterization, and Dissolution techniques.
