We are delighted to announce that Metallomics will be publishing a themed web collection from the 6^th International Symposium on Metallomics 2017 with Gunda Köllensperger and Bernhard Keppler as guest editor. We welcome papers based on oral or poster presentations given at the meeting and there will be no limit to the number of papers an author can submit. All submissions will be subject to initial assessment and peer review in the usual manner and must meet the scope, standards and requirements for the journal.

Manuscripts should be prepared according to the Author Guidelines available on the journal website. The submission deadline for the papers is 30 September 2017. Accepted papers will be published on the RSC website as Advance Articles as soon as they are ready and published in the next available issue of the journal. All accepted papers will be gathered together in an online web collection on the Metallomics webpage.
