The cover picture shows the formation of highly hydrated and metastable calcium carbonate (CaCO 3 ·6H 2 O) crystals containing carboxylated dextran‐stabilized magnetite (Fe 3 O 4 ) nanoparticles. These crystals are microwave heated, the bound water and magnetite particles both acting as microwave absorbers. The water present is rapidly expelled as steam to form remarkable open‐framework CaCO 3 supports, decorated throughout with attached magnetite nanoparticles. These porous composite structures can act as functional catalysts, for example, as a self‐buffering co‐catalyst for visible light‐driven water oxidation. For more information, please read the Communication “Synthesis of Macroporous Calcium Carbonate/Magnetite Nanocomposites and their Application in Photocatalytic Water Splitting” by D. Walsh, F. Meldrum, and co‐workers, beginning on page 2168 .
