This cover was designed by Jie for an article published in Chem. Eur. J. (2010, 16, 12559-12563). It shows the color changes associated with colloidal suspensions of silver nanoplates upon exposure to air at a specific temperature. The intrinsic structural instability and striking color changes associated with the nanoplates make them particularly useful as a reliable recorder of environmental factors. Such nanomaterials can serve as indicators of time and temperature for various commercial needs.

This cover was designed by Jie for an special issue of Adv. Mater. (Volume 22, Issue 17. May 4, 2010). It shows a gold medal presented by the editors to the University of Science and Technology of China (USTC) for outstanding achievements in producing a cadre of well-trained, independent investigators who can proficiently spearhead cutting-edge research in advanced materials and nanotechnology.
