About this collection

We are delighted to celebrate Journal of Materials Chemistry C’s tenth anniversary in 2023!

This special issue celebrates and thanks members of our community who have supported the journal over the last ten years, and we are honoured that these authors have shared their latest discoveries with us.

Ten years ago, with the launch of the three separate titles, the vision of Journal of Materials Chemistry A, B and C was to provide venues for highly topical research in a broad range of materials chemistry and this is exemplified in the three anniversary issues, which highlight diversity in its broadest sense, across the global materials chemistry community and covering the full breadth of our discipline.

We believe that Journal of Materials Chemistry A, B and C will continue to be the home of innovative, and impactful materials chemistry research for many years to come and hope you enjoy reading the diverse range of papers featured in the anniversary issues.
