Electron beam-induced demetallation of Fe, Co, Ni, Cu, Zn, Pd, and Pt metalloporphyrins: insights in e-beam chemistry and metal cluster formations
By operando high-resolution transmission electron microscopy, we show that slow secondary electrons from the specimen can demetallate metalloporphyrins. This general approach allows study of the dynamics of various single metal atoms and metal clusters.

Anti-Arrhenius passage of gaseous molecules through nanoporous two-dimensional membranes
Temperature variations reveal a gating effect on molecular permeation across two-dimensional membranes. The reason appears to be adsorption–desorption equilibria on the membrane surface.

About this collection
Recognising that physical chemistry stands at the centre of efforts to obtain a deeper understanding of materials and molecular processes involved in energy transformation that hold the keys to future technology innovation and development, the DBG and the organizing committee of this year’s Bunsen-Tagung are pleased to showcase contributions describing recent research in physical chemistry either to the main topic of energy transformations or to the general topics of Physical Chemistry.
This themed collection is Guest Edited by Timo Jacob (Ulm University), Swetlana Schauermann (Kiel University), Robert Schlögl (Fritz Haber Institute of the Max Planck Society), and Alec Wodtke (Georg-August University & Department of Dynamics at Surfaces, Max-Planck-Institute for Multidisciplinary Sciences).
