During photosynthesis, nature uses an enzyme with a manganese–calcium core for water oxidation. Here, the authors report the synthesis of a stable, water-soluble manganese cluster that acts as a homogeneous water oxidation electrocatalyst, displaying low overpotential and high Faradaic efficiency.
Control over nanoparticle atomicity has not yet been extended to metal oxides. Here, the authors present the synthesis and X-ray crystal structures of a family of atomically precise ceria nanoclusters, a pivotal step for understanding the relationship between their atomic structure and reactivity.
C-type inactivation is a process by which ion flux through a voltage-gated K+ channel is regulated at the selectivity filter. A recent structure of the Kv1.2 channel provides a view into the structural changes of the selectivity filter during C-type inactivation.
Mathematically modelling metal–ligand bonding in late transition-metal complexes has been an important tool in catalyst development — although lacking for early transition metals such as Cr and Ti. Now, a simple method for measuring ligand donor properties promises to elevate high-valent early transition metal catalysis to the same level.
Our understanding of actinide chemistry lags behind that of the rest of the periodic table. A collection of articles in this issue highlights recent progress featuring uranium(VI) dianions bearing four U–N multiple bonds, berkelium(IV) stabilized in solution and delocalization of 5f electrons in a plutonium material.
