Introduction
Modern material engineering pays great attention to creating "smart" adaptive materials for various applications.
One of the most interesting classes of such systems is photosensitive organic materials.
Thus, the combination of various environmental effects opens new possibilities for the structure control and, ultimately, design of new "smart" materials.
To study the effect of different external factors on the materials structure a unique setup, that includes UV-lamp and heating/cooling stage, was developed.

Raw materials applied in power generation are
mostly sawdust and fibrous fragments [2], as a consequence, key equipment in the production of
wood powder is superfine wood powder disintegrator.
Sawdust or broken fiber materials whose granularities are rough are crushed into the wood powders that are in line with size of the requirements for power generation through triplex impact effects such as impact effect between particles and the dynamic and static cutters, impact effect between particles and particles and impact effect between particles and the shell.
The fixed cutters are divided into four layers up and down, and combination of the fixed cutters and the corresponding dynamic cutters realize to break up with raw materials of the wood powder.

Abstract.
Most people use the anatase and carbon black as starting materials of synthesizing titanium nitride [3].
Although the carbon black is the best material the cost is too high.

Abstract.
Glass is 100% recyclable and one of the safest packaging materials due to its composition and properties [3,4].
The data obtained in this study should be helpful in potential applications in Pb-free x-ray shielding materials.
