It turns out that the chemical structure of successfully prepared gel-type wood composite material does not changes and its microstructure retains a complete timber microscopic structure.
Therefore, to find an ideal solvent with good cellulose dissolving ability is one of the urgent difficulties for cellulose chemistry to solve.
Cellulose molecular chain structure and Figure.2.
In slitting plane, the bare cell cavity structure is exposed after the cutting.
Moreover, this structure becomes looser

Keywords: Zn-Al-Cu alloys, corrosion resistance, REE, structure.
Results of examination The as-cast ZnAl22Cu3 alloy is characterized by dendritic structure.
For base alloy the highest copper content was observed in the border zone with the "healthy" structure.
Fine-grained structure disadvantageously influences on resistance to electrochemical corrosion.

Lignin FTIR spectra had obvious differences at 3400cm-1, which was attributed to OH groups in phenolic and aliphatic structures.
Obviously, a remarkable increase of carboxyl absorption observed in acetic acid lignin spectrum revealed that a noticeable oxidation of the lignin structure did occur during the organic acid treatment.
SEM and FTIR analyses proved that the acetic acid processes had great influence on lignin structure and pulp fiber surface.

Additionally, there was no new crystalline phase for N-TiO2 and N, Cd-TiO2, illustrating that the nitrogen and cadmium doping did not change the catalysts structure.
The addition of nitrogen and cadmium played the synergistic effect in modification the structure of TiO2, which enhanced the photocatalytic performance of TiO2.
Doping led to the crystal structure distortion, crystallinity reduction, and the specific surface area increasing, with the photocatalytic activity increasing.

Abstract.
According to Mariatti et al. [7] the alkali treatment destroyed the cellular structure of the bagasse fiber resulted in a compressed structure which could act as thermal insulators.
Cao et al. [10] reported that the alkali treatment decreased bagasse fiber diameter by the compression of cellular structure which could enhance the mechanical properties of the composite.
