Pan, in: Proceedings of 2013 International Conference on Frontiers of Energy, Environmental Materials and Civil Engineering, Shanghai, China

Forty-three papers selected by the Editors for inclusion in this volume are thematically pressented in eight sections: I Atomic Layer Engineering; II Electrochemical Processing; III Nanostructured Materials; IV Fullerenes and Nanotubes; V Biomaterials; VI Polymers and Composites; VII Physical Metallurgy; and VIII Spectroscopic and Structural Characterization.
Dear colleagues, I would like to take this opportunity to express my personal view on both the general situation in the country and the status of materials science and engineering in the period between the two Conferences.
The danger and fear of civil war is present.
On the other side, dear colleagues, it is well known that the materials science and engineering in the west are reaching heavenly heights.
