Outline of Final Research Achievements

Scanning Probe Microscope, which can detect both geometry and properties, was used for observation on wood cell walls. The phase difference on the surface was able to tell the cellulose from matrix in a cell wall. Cellulose aggregated into a microfibril, the size of which was 15 to 20 nm, in a cell wall.
Layered nanostructure was seen on transverse cell wall. That structure seemed to consist of several microfibrils. Cell wall thickening diurnally, the nanostructure must be focused.
