No. 12 December 2019
Scaling relationships have been established between certain physical or chemical properties of heterogeneous catalytic reactions. In this Review, these properties, or reactivity descriptors, are described and their ability to predict catalytic performance, and thus enable the rational design of catalysts are outlined. See Zhao et al.

2D materials exhibit diverse properties and can be integrated in heterostructures: this makes them ideal platforms for quantum information science. This Review surveys recent progress and identifies future opportunities for 2D materials as quantum-dot qubits, single-photon emitters, superconducting qubits and topological quantum computing elements. See Liu & Hersam.

No. 9 September 2019
Despite their excellent macroscopic operational parameters, halide perovskites exhibit heterogeneity in materials properties at all lateral and vertical length scales. This Review discusses heterogeneity in halide perovskites and assesses the impact of these non-uniformities on their optoelectronic properties and how heterogeneity may be beneficial for device properties.

No. 4 April 2019
Oxide superlattices reveal emergent phenomena if the balance between competing degrees of freedom is altered. In this Review, synthetic approaches to tap the properties of competing ground states are described, focusing on an example yielding a room-temperature multiferroic and another example producing polarization skyrmions. See Ramesh & Schlom
