Silica is one of the most referenced materials for the preparation of heterogeneous metal catalysts. However, silica spheres with smooth surfaces have difficulty encapsulating active metals due to their small surface area and the presence of only a handful of silicon hydroxyl groups on the...

The control of the interface states between the electric contacts and semiconductor is a key issue to develop high-performance functional devices. In this work, a serial of surface treatments including mechanical polishing (MP) + chemical polishing (CP) + surface passivation (SP) were conducted...

This study investigates the role of analysts on the relationship between trend information and cross-sectional returns. Our results show that the trend information about past price and trading volume significantly predicts future stock returns in the Chinese stock market. The trend effect is...
