chs²

The Organizing Committee has closely monitored the evolution of the pandemic. Due to the present global situation and the uncertainties about travelling restrictions next year, we have decided to postpone the CHS² conference to 2022.

The organizing committee would like to thank all the corresponding authors for the interest and support to the CHS2 event, despite the difficult times we live in, the number of submitted abstracts are around 85% of that in previous conferences. The present authors can keep their abstracts as submitted. You can also withdraw your abstract, update it with fresh content or submit new abstracts before the new abstract deadline 14th October, 2021.

We are looking forward receiving your highly interesting papers and seeing you in World Trade Center, Barcelona, 30th May to 2nd June, 2022.
