Hierarchical functional nanocomposites

Composites Composite materials are constructed from materials that vary in size. Nanoscale materials have unique properties that may be very useful for developing new types of devices. Begley et al. review synthesis and assembly methods for functional nanocomposites with a focus on potential applications. Some challenges include scaling and ensuring mechanical stability. Combining new developments from a range of disciplines will be key for enabling advanced device concepts. Science , this issue p. [eaav4299][1] [1]: /lookup/doi/10.1126/science.aav4299
