Thanks to blasting peers' attention and submitting abstracts to Fragblast 13 in the context of the ongoing pandemic through the world, we have received 121 abstracts from 13 countries this year. In the hope of having more blasting peers from more countries to join the symposium physically or online, we have decided to postpone the abstract submission deadline to March 1, 2022. Thereby, the deadline for notifications of acceptance will be postponed  to April 1, 2022. But we will try to make a feedback as soon as possible to those who have submitted their abstracts.
