3D resonators for spectral processorsSpectral processors for wireless communication can be created using acoustic resonators made from 3D silicon nano-fins with hafnia–zirconia ferroelectric gates wrapped around them. The scanning electron microscopy image on the cover shows an array of filters created by electrically coupling 3D resonators with different frequencies, with the different devices highlighted by different false colours.

Recapture and reuseWith the help of processes that can recycle organic conductors, semiconductors and dielectrics, flexible electronic devices can be created in which each component of the device can be recaptured and reused. The computer-generated image on the cover shows a flexible electronic device developed using this closed-loop recycling approach.
