Abstract: A super strong and tough densified wood structure is formed by subjecting a cellulose-based natural wood material to a chemical treatment that partially removes lignin therefrom. The treated wood retains lumina of the natural wood, with cellulose nanofibers of cell walls being aligned. The treated wood is then pressed in a direction crossing the direction in which the lumina extend, such that the lumina collapse and any residual fluid within the wood is removed. As a result, the cell walls become entangled and hydrogen bonds are formed between adjacent cellulose nanofibers, thereby improving the strength and toughness of the wood among other mechanical properties. By further modifying, manipulating, or machining the densified wood, it can be adapted to various applications.

Abstract: An ergonomic modular ergonomic multi-layer platform with a synthetic tapered marginal border including a non-compressible wood base covered with at least one compressible mat disposed between the wood base and a top non-slip mat to provide occupational workers with a therapeutic, forgiving work surface to protect them from the health risks of working, walking and standing on a concrete floor or common anti-fatigue mat used in many factories today. The therapy platform is raised off the floor to offer suspension, thus promoting a spring effect for absorbing and returning compression force resulting in reduced stress loads and compression force for people who work, walk or stand fort extended periods of time. The therapy platform is modular in design so that the tapered borders of separate modular sections connect for a snug fit. The vertical edges of the wood sections also have connection points that provide a leveling effect and further enhance the fit of the module sections.
