About this collection

The annual #RSCPoster Twitter Conference (https://rsc.li/poster) is our flagship celebration of science, drawing together researchers to network with peers, engage in scientific debate and share their research with the global chemistry community. The event takes place for just 24 hours on Twitter each year but following feedback from participants, we are showcasing work from poster presenters in this collection to give a more permanent home to the research presented.

If you have participated in an #RSCPoster and would like to present your work in this collection, please see our survey at https://www.smartsurvey.co.uk/s/RSCPoster/. Please note that to be featured, your work must be published in a Royal Society of Chemistry journal; we cannot display articles at other publishers on this platform. We will be continuously updating the collection and adding articles as requested by presenters, so please return to this page to view the latest works from the #RSCPoster community.
