In this issue, F. Zhang et al. review luminescence lifetime imaging based on lanthanide nanoparticles, and G. K. S. Prakash et al. summarize work on low-temperature catalysis of the homogeneous hydrogenation of CO₂ and CO to methanol. The Minireviews deal with upgrading organic compounds through the coupling of electrooxidation with hydrogen evolution (X. Feng et al.) and energy transfer from chemiluminescent spiroadamantane 1,2-dioxetane probes for bioanalyte detection and imaging (H. N. Kagalwala, A. R. Lippert). In a Scientific Perspective, S. Grimme et al. suggest best-practice DFT protocols for basic molecular computational chemistry.

In the original research section, T. Haino et al. report the synthesis of metal nanoparticles on lipophilic nanographenes (see picture). E. Anaya-Plaza et al. found a greener route to blue through the solid-state synthesis of phthalocyanines. M.-R. Gao et al. suppressed electron back-donation for a highly CO-tolerant fuel cell anode catalyst via cobalt modulation. F. Dielmann et al. succeeded in the oxidative fluorination of selenium and tellurium compounds using a thermally stable phosphonium SF₅⁻ salt accessible from SF₆.
