Our increasing understanding of non-covalent interactions involving aromatic systems is reviewed, and the use of these insights in the design of small-molecule catalysts and enzymes is surveyed.
The recent expansion of observational data has changed our understanding of the ocean iron cycle and its linkages with nutrients such as carbon and nitrogen.
The experimental state-of-the-art in the field of chiral quantum optics is reviewed and the ways in which chiral light–matter interaction could be exploited to add a new dimension of control to quantum networks and quantum many-body physics are discussed.
