<jats:title>Graphene nanoribbons made on oxides</jats:title> <jats:p> Atomically precise nanographenes and nanoribbons have been synthesized on metal surfaces that catalyze cyclode-hydrogenation of precursors. However, for use in devices, these structures usually must be transferred to insulating or semiconducting surfaces. Kolmer <jats:italic>et al.</jats:italic> synthesized precise graphene nanoribbons on the surface of rutile titanium dioxide (TiO <jats:sub>2</jats:sub> ) that assisted the cyclode-hydrofluorination of specifically designed precursor molecules through a series of thermally triggered transformations. Scanning tunneling microscopy and spectroscopy confirmed the formation of well-defined zigzag ends of the nanoribbons as well as their weak interaction with the substrate. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6503" page="571" related-article-type="in-this-issue" vol="369" xlink:href="10.1126/science.abb8880">571</jats:related-article> </jats:p>
