Metal–organic frameworks (MOFs) have shown promise in a broad range of applications, including catalysis. In this Review, the chemical, thermal and mechanical stabilities of MOFs, in particular with catalytic uses in mind, are discussed.

Acoustic metamaterials can be used manipulate sound waves with a high degree of control. Their applications include acoustic imaging and cloaking. This Review outlines the designs and properties of these materials, discussing transformation acoustics theory, anisotropic materials and active acoustic metamaterials.

Single-molecule electronic junctions comprise three components: anchors, electrodes and the molecular bridge. This Review surveys the relationship between the chemical structures and the electronic properties of each component, and extends the discussion to switching functions and the phenomenon of quantum interference.

Grafting DNA strands onto colloidal nano- and microparticles endows them with sequence-specific interactions. This Review explains how these interactions emerge from reactions between the strands and how the DNA sequences can add information that tells the particles how to self-assemble.
