In this issue, T. Nguyen et al. review the promotion of organic reactions by non-benzoid carbocyclic aromatic ions. What is their potential in synthetic chemistry? In a Minireview, C. Wesdemiotis summarizes multidimensional mass spectrometry of synthetic polymers and advanced materials.

In the Communications section, K. Zhu et al. present a bioinspired antibacterial heptapeptide (see picture). Y. Tsuji et al. succeeded in the boraformylation and silaformylation of allenes, and J. Gaubicher et al. used lithium n-doped polyaniline for rechargeable batteries.
