Historical Background The application of nanosized materials is much older than today’s science, and dates back to ancient Egyptian, Chinese, and Roman times.
In materials science, zinc oxide is classified as a semiconductor in group II-VI, whose covalence is on the boundary between ionic and covalent semiconductors.

The library to provide users with academic research material, and some common service website can only provide to the user general information, such as weather forecast, news, etc., can't meet a full range of information needs.
At present domestic existing Chinese academy of sciences, the national science digital library, Hainan university library, Xiamen university, Zhejiang university library and launch My library personalized service, the user can from the library network to provide all of the library digital resources, to select the desired information organization to their own web pages, establishing access personal database for future.
The Chinese academy of sciences such as libraries use this model to carry out joint western journal title side service, Chinese academy of sciences Shanghai literature information center to carry out new book information delivery.
