In this work, both fluorine and nitrogen were considered as potential dopants to be incorporated in the TiO2 structure.
Powder X-ray diffraction (Bruker D8 Advance) was utilized to observe phase structure of the as-prepared materials.
The presence nitrogen and fluorine in the TiO2 structure was confirmed by CHN and energy dispersive X-ray (EDX) microanalyses, respectively.

A similar dense homogeneous structure was also observed when a high bias voltage (-250 V) was applied during dc magnetron sputtering [9].
This second generation of MuBiNaFs was shown to possess a nanocomposite structure with various functional groups on the film surface that stimulate accelerated osseointegration.
Surface chemistry versus surface roughness The interaction between an implant and surrounding tissues is a complex dynamic process whose efficiency largely depends not only on the implant surface chemistry but also on the surface topography and roughness.
Yet the question arises as to whether it is possible to obtain a synergetic effect by a proper choice of both surface chemistry and roughness.
It was also shown that the bioactivity of Ti surfaces can be well controlled by a proper choice of surface chemistry and topography.

Introduction
For hydrofobic features of wooden structures covered with paints the durability of their protective action depends on the adhesion forces between paint coating and wood surface, i.e. the magnitude of adhesion.

Introduction
Zincophosphates as a multi-functional materials are especially interesting for their rich structural chemistry and compositional diversity.
To date, there are about 100 kinds of zincophosphates having chain, layered and n-dimensional framework structure have been reported and developed [1, 2].
We began to prepare thermostable zinc phosphates using inorganic ion in stead of organic amine as a structure topology agent.

The results show that the catalyst was the tetragonal primitive crystal structure and composed of homogeneous particles of fine ferrite plates.
The crystalline quality and crystal structure of BiOBr samples were examined by XRD and the diffraction pattern is shown in Fig.1.
From above results, it can be concluded that the BiOBr catalyst has a tetragonal crystal structure and fine ferrite plates.

Keywords: Soft Chemistry; NdxCo2-xZr2O7; Ammonium Perchlorate (AP); Catalysis; Thermal Decomposition.
The nano particles obtained had a perfect crystal structure, good dispersion, and the size was about 31nm.
The crystal structures were determined by German Bruker D8Advanc type X-ray powder diffraction (XRD).
The pyrochlore structure of Nd1.9Co0.1Zr2O7 can be confirmed by FT-IR and Raman.
Small changes in crystal structure would lead to the change in the Raman spectra.
