Confining effect of oxide film on tin whisker growthYushuang Liu1,Peigen Zhang1,Jin Yu1,Jian Chen1,Yamei Zhang2,Zhengming Sun11. Jiangsu Key Laboratory of Advanced Metallic Materials,School... to be modulated by oxide film. A striated whisker morphology forms as growing in air, whereas a faceted morphology forms in vacuum.Furthermore, the evolution to the faceted morphology is attributed......

. On the sites where the fluoride film is not complete or dense, oxide (MgO/Mg(OH)2) can be formed after samples are taken out of the activation solution, since magnesium has a very high chemical activity and the formation of magnesium oxide on the surface is rapid. Additionally, the different activation solutions and pretreatment affect the composition of fluoride film, particularly on the F/O ratio......

The as-prepared powder was made into a soliquoid,from which films were made by dip coating process with indium-tin oxide(ITO).The obtained films were characterized by thermogravimetric......
Photocatalytic oxidation activity of titanium dioxide film enhanced by Mn non-uniform doping ZHANG Kai-jian(张开坚)1, 3, XU Wei(徐 伟)2, 4, LI Xin-jun(李新军)2, ZHENG Shao-jian(郑少健)2, XU Gang(徐 刚.... Each film was characterized by XPS, SEM, UV-vis spectrophotometry and electrochemistry workstation analysis. The activity of the photocatalyst was evaluated by the kinetics of photocatalytic......
with specific capacitance of 782 F/g. Besides, it is found that the specific capacitance of the film decreased by roughly 20% with voltage scan rate increasing from 5 to 250 mV/s.Key words:ruthenium oxide...Composition change and capacitance properties of ruthenium oxide thin filmLIU Hong(刘泓)1, GAN Wei-ping(甘卫平)2, LIU Zhong-wu(刘仲武)1, ZHENG Feng(郑峰)2(1.

depth profile analysis showed that the surface oxide film could be pided into three sub layers. The outside layer was mainly made up of magnesia, the middle layer, which consisted of beryllium oxide, magnesia and aluminum oxide, was compound and compact, the inside layer was a transition layer to substrate. Thermodynamic analysis indicated that the structure of the surface oxide film was accordant......
