      The cover picture shows the molecular level defect healing based on spiropyran solid film during UV/Vis light triggered process. Self-healing is one of important properties in nature, especially in the field of nano surface science. Spiropyran thin film with capability of light-triggered molecular level self-healing has been successful designed and fabricated by Langmuir-Blodgett technology. Various remarkable shrinkage or height increase or nano-defect recovery of the thin film has been observed, attributing to the self-healing effect. In addition, further evidence of self-healing process has also been observed, which resulted from the movement of spiropyran molecules. More details are discussed in the article by Zhang et al. on page 1483–1487.

      Six new bis(o-diiminobenzosemiquinonato)nickel(II) complexes bearing halogenated diiminobenzosemiquinonato backbone and/or halogenated phenyl substituents on the imino nitrogen have been synthesized and characterized by spectroscopic methods. Cyclic voltammetry studies on these complexes revealed the ease of reduction of these complexes parallels the electron-donating and -withdrawing ability of the substituent group.

    2. Light-Triggered Molecular Level Self-Healing Spiropyran Thin Film (pages 1483–1487)

      Bingjie Yang, Juehuan Liu, Hongzhi Zheng and Sean Xiao-An Zhang

      Spiropyran thin film with capability of light-triggered molecular level self-healing has been successfully designed and fabricated by Langmuir-Blodgett technology. Various remarkable shrinkage or height increase or nano-defect recovery of the thin film under different fabrication conditions was observed by AFM, attributing to the self-healing effect. In addition, further evidence of self-healing process has also been observed from the reversible contact angle (CA) change of the thin film, which resulted from the movement of spiropyran molecules.

      The figure shows the correlation between prediction and experimental values. The outputs of the CSPSO-FC RBF ANN model show a fair agreement with the experiment. It could also mean that the proposed model has excellent prediction capability and has good correlation with the experimental data. The results indicate that our proposed model outperforms PSO ANN and RBF ANN.
