The current ChemistryOpen issue features the group of F. Matthias Bickelhaupt and their computational work on geometries adopted by d¹⁰-ML₂ transition-metal complexes. The front cover and cover profile nicely complement their Full Paper and give interesting and valuable background information on their work and the incentive behind it. The Full Paper by Marc Steinmetz and Stefan Grimme presents a further computational paper that reports on an extensive benchmark for evaluating modern density functionals in transition-metal-catalyzed bond-activation reactions.

 Two other papers in this issue also revolve around transition metals. Yan-Yan Song, Patrik Schmuki and co-workers use self-organized TiO₂-nanotube layers in combination with CdTe quantum dots for immunoassay-type detection and achieve excellent detection limits with this electrochemiluminescent technique. Narayane S. Hosmane and colleagues, on the other hand, synthesize nanocomposites of Fe₁₀BO₃/Fe₃O₄/SiO₂ and GdFeO₃/Fe₃O₄/SiO₂ using a gel combustion technique for potential applications in diagnostic analysis of cancer through use in neutron capture therapy.
