Controlled Growth of ZnO with Different Morphologies on Zn Foils by a Simple Aqueous Solution Method Qingling Sun, Yongqin Chang*, Changjing Shao and Yi Long School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China xrd2009@sina.com, *chang@ustb.edu.cn, 13370153163@126.com, longy@mater.ustb.edu.cn Keywords: ZnO, Morphology, Controlled growth, Cl ion, Solution method.
In this work, ZnO materials with different morphologies were deposited on Zn foils by a simple aqueous solution method, and the shape of ZnO can be controlled by the concentration of Cl ions in the solution.
The competition between Cl ions and growth units in the solution results the formation of ZnO materials with different morphologies.

Performance of on-site assembly is simple and reliable ,convenient transportation, separation.So it is widely used in mining, metallurgy, building, materials, railway and other industries [1-4].
From the waveform of vibration can be seen in Figure 5:(1) With the start of crusher, The vibration signal of the eccentric shaft bearing seat began changing and until after completion of starting stage into stable no-load operation;(2) Vibration which crusher broken material is the most intense vibration;(3) Vibration amplitude corresponding to frequency of loading conditions is larger than no-load condition,so it is in line with the actual conditions of crusher.

Introduction In resistance spot welding, the thermal expansion of the weld area is measured by electrode displacement during spot welding, which reflects the direct thermal responses of the joint materials to the welding conditions.
At the initial stage of heating the rate of change of displacement is inversely proportional to the electrode force for both materials.
Material: 1.5-1.5mm aluminum.

Intorduction In recent years, nanostructural materials have been intensively studied due to both scientific interests and potential applications [1,2].
Moreover, ZnTiO3 doped with some transition metal ions has been widely researched as one of the most promising luminescent materials due to its environmental friendliness and low cost [8, 9].
This route may open a new door to make nanofibers of inorganic materials.
