With the right app, smartphones can become a powerful tool for teaching physics and for increasing the popularity of this important subject.

Resistive switching materials enable novel, in-memory information processing, which may resolve the von Neumann bottleneck. This Review focuses on how the switching mechanisms and the resultant electrical properties lead to various computing applications.

Compounds that adopt the ReO₃-type structure, like their perovskite counterparts, are both numerous and wide ranging in their chemistries and their properties. In this Review, the similarities between the subfamilies of this exciting class of materials are illustrated, showing that often the materials are more alike than they are different.

The preparation of multiphase nanodroplets has enabled the fabrication of emulsions with novel structures and functions for nanomaterials design and formulation. In this Review, the strategies and challenges to produce, stabilize and characterize such multiple nanoemulsions are discussed, as well as the applications they enable.

Solid-state batteries based on electrolytes with low or zero vapour pressure provide a promising path towards safe, energy-dense storage of electrical energy. In this Review, we consider the requirements and design rules for solid-state electrolytes based on inorganics, organic polymers and organic–inorganic hybrids.
