where [[mu].sub.total] = total porosity (%), which is equal to fractional volume occupied by air plus water fraction in green condition [V.sub.p0] = oven-dry true volume of wood cell
The densified wood--referred to as Super Wood--has a unique microstructure, in which the fully collapsed wood cell
walls are tightly intertwined along their cross-section and densely packed along their length.
In 2018, the Group was awarded the "2017 State Science and Technology Improvement Award" (Second Class) in respect of material modification and functionalization technology based on modification of wood cell
, as well as the "High and New Technology Enterprise Certificate" which allows the Group to enjoy preferential taxation until 2019.
The interfacial bonding between the wood cell
wall and monomer mixture was examined using a scanning electron microscope (TM3030) supplied by JEOL Company Limited, Japan.
The template was prepared by removing the light-absorbing lignin component, creating nanoporosity in the wood cell
walls are composed of cellulose, hemicelluloses and lignin (Stefanidis et al, 2014).

(20) Silica nanoparticles, although having a low modulus (88.7 GPa) (21) compared to that of the nanoclays (170 GPa), (22) if well dispersed in the primer formulation, could enhance the mechanical properties of primer which has partly diffused in wood cell
cavities at the surface.
The maximum wood moisture content allowing fungal growth is determined by the minimum air content within the wood cell
. The tunnel within wood cell
walls produced by hyphae of wood decay fungi [4,9] appears to be a unique form of fungal decay different from any of the well known fungal decay types.
Additionally, the SEM-EDS images of the samples treated with both phosphorus flame retardants and Si[O.sub.2] sol (S5) indicate that the P and Si elements exist concurrently in the wood cell
. This means that phosphorus based flame retardants and Si[O.sub.2] sol can reside in the poplar wood since poplar wood itself does not have P and Si elements.
