The factors responsible for friction from bracket and archwire interface include: the size and shape of the wire, bracket type, bracket and wire materials, angulation of the wire relative to the bracket, type of ligation, environment (wet or dry), and surface coating.
Previous studies had investigated Methane (CH4) and Tetrafluoromethane (CF4) Plasma-Based Ion Implantation (PBII) to modify the surfaces of materials such as metals, plastics and ceramics.
Materials and Methods Preparation of Surface Modified NiTi Archwires. 0.016 × 0.022-inch NiTi orthodontic archwires from Smartmat Innovation Co., Ltd. were deposited with DLC films and were implanted with CH4 and CF4 using Plasma-Based Ion Implantation and Deposition (PBIID) method (Fig. 1).

The new materials industry started later in the development zone, but due to its development in recent years, the new materials industry is facing a better market prospect.
Regarding the strategies for the introduction of new materials enterprises, we suggest that the development zone should introduce enterprises with independent research and development capabilities in new materials industry.

To understand the strength behavior of solidified waste matrices as building materials, sewage sludge as a kind of municipal solid waste had been solidified/stabilized by a binder constituted of Portland cement and stone material powder.
Some researches have been reported that the strength of solidified sludge matrices can meet the requirement of materials for road use or other building materials[4,5,6].
Stone material powder is a kind of material waste produced during the stone materials polished process and is found feasible to substitute for part of Portland cement as a solidifying aid.

The binder materials were mixed in a definite ratio as given in Table 3.
Two groups of solidified waste matrices were prepared by mixing different proportions of binder materials.

In addition, this process could also be observed by naked eyes because the structure color of the materials was also changed.
Thus, the melting point of the materials could be detected by our method without using complex and expensive analyzer.
In practice, the methods were index stimulated responsive materials, using stimulated responsive materials to change the index or structure of them.
