Winners Announced

Thank you to everyone that entered this year's cover competition: once again, we received many fantastic entries. Each of the ten winners below will have their image featured on the cover of an issue of the Materials Today  journal in 2019, and will also write for the journal, as part of our Uncovered feature.

We will remind you when each Uncovered article is published, so keep up to date by signing up to receive the issue alert here.
