The structures of the ZnS films were confirmed by an X-ray diffractometer with a Cu-Kα radiation source (λ=1.5406 Å).
Structure For ZnS, there are usually two kinds of structures, sphalerite structure (cubic forms) which is stable at room temperature and wurtzite structure (hexagonal forms) which is stable at high temperature.
Al electrodes Thin films Substrate Fig.5 The designed sample structure for resistivity measurement.
The ZnS thin films with cubic structure are polycrystalline and have a preferred orientation in (111) plane.

Precursor TiO2 presented a broad diffractions at 2θ= 25, 37, 38, 39, 48, 54, 55, 63, 69, 70 and 75 related to anatase structure (Fig. 1).
While in the latter dosage, the chemical structure of nondegradable organic matter was shifted and they were decomposed to degradable intermediate products, so the contribution was less for COD removal in the latter dosage.

Materials physics, chemistry can guide the synthesis of new materials research.
Study the new material needs of the organization, structure, composition distribution of atoms, combined with a more subtle relationship between the observed, more clearly; the material at room temperature and high temperature macro-and micro-chemical analysis need to be more accurate, sensitive, and convenient; test materials physics and chemical properties should be more accurate, simple; need to be able to accurately, quickly and easily test, analyze material in the melting or softening temperature or the cooling process of solid-state transformation and deformation process, combined with state of the atom, atomic diffusion migration, changes in motion and crystal defects organizational status, performance status, and the actual situation.
Present and future may have important research value and may result in breakthrough areas of new materials: magnesium alloys and magnesium matrix composites and other light metal materials to replace steel and other structural materials, parts or as a supplement functional materials; with ultra-performance Nano-materials and non-crystalline materials; high-performance carbon / carbon composites and other inorganic materials; special performance or functional polymer; high-performance composite materials and composite material; advanced ceramics; biological materials; storage or energy conversion materials; high-temperature superconducting materials; high performance of the sensor material; special functional materials; significant performance optimization of conventional metal structure materials.

The adsorbent surface area is directly proportional to the amount of adsorbent on a certain structure.
As it is strong, which has a greater impact on the structure of the adsorbed molecule, chemical adsorption is looked on as a chemical reaction.
