Five Years of ChemRxiv: Where We Are and Where We Go From Here.

ChemRxiv was launched on August 15, 2017 to provide researchers in chemistry and related fields a home for the immediate sharing of their latest research. In the past five years, ChemRxiv has grown into the premier preprint server for the chemical sciences, with a global audience and a wide array of scholarly content that helps advance science more rapidly. On the service's fifth anniversary, we would like to reflect on the past five years and take a look at what is next for ChemRxiv.

Editorial: Introducing… Advisory Editors and New Author Profiles at Angewandte Chemie.

One year ago, Angewandte Chemie pledged to become a more inclusive and diverse journal. We have made significant progress, but our work is not done. Starting today with the inaugural ten Advisory Editors of the journal and our new Author Profiles "Introducing…", and continuing over the next several months, we are pleased to share our achievements so far and our plans for the future.

Three Chemistry Europe Council Members Retiring.

After many years of the representing Chemistry Europe and its predecessors, three of its Presidents are retiring. In this Guest Editorial, their Chemistry Europe Council colleague, Wolfram Koch, looks back on their many contributions to European science publishing.

Mindo/3 and mndo calculations of closed- and open-shell cations containing C, H, N, and O.

Heats of formation of 119 closed- and open-shell carbocations calculated by the semiempirical quantum chemical methods MINDO/3 and MNDO are reported and compared with experimental data. With proper consideration of failures in specific areas, both methods can be used for the thermodynamics of carbocations containing C, H, N, and O. MINDO/3 predicts unrealistic values for nitrogen containing cations with nitrogen multiple bonds and is not suited for closed-shell cations containing oxygen.
