In this issue, F. R. Wurm et al. review molecular firefighting. How can modern phosphorus chemistry help solve the challenge of flame retardancy? D. M. Haddleton et al. discuss copper-mediated reversible deactivation radical polymerization in aqueous media in a second Review. The Minireviews deal with nanoscale chemical imaging of zeolites by atom probe tomography (B. M. Weckhuysen et al.) and 3D DNA origami nanoparticles (A. Walther et al.). P. Goya and S. Dehnen contribute Editorials on the 2018 EuCheMS Congress in Liverpool and mainstream vs. original reseach, respectively. R. von Klitzing and T. N. Zemb honor the legacy of Helmuth Möhwald in an Obituary; he is also a co-author of a Communication on 2D polymer synthesis at the air/water interface.

In the Communications section, D. A. Leigh et al. secure a supramolecular architecture by tying a stopper knot (see picture). H. F. Bettinger et al. present undecacene in the evolution of the optical gap in the acene series. M. Barboiu et al. describe the structure-driven selection of adaptive transmembrane Na⁺ carriers or K⁺ channels. S. P. Thomas et al. succeeded in the manganese-catalyzed hydrofunctionalization of alkenes.
