Back Cover: Polymerization under Hypersaline Conditions: A Robust Route to Phenolic Polymer-Derived Carbon Aerogels (Angew. Chem. Int. Ed. 47/2016).

The polymerization of phenol–formaldehyde resin under hypersaline conditions, for example, in the presence of ZnCl2, generates a black monolith. In their Communication on page 14623 ff., N. Fechler, M. Antonietti, S. H. Yu et al. further show that a foam‐like carbon aerogel with good mechanical robustness can be directly obtained from the monolith without any special drying processes. ZnCl2 plays a key role in this process, serving as dehydration agent, foaming agent, and porogen. [ABSTRACT FROM AUTHOR]
