While thanking the wide participation of dear researchers in the 8th zeolite conference of the Iranian Chemical Society, we would like to remind you that according to the request of some researchers, the deadline for submitting articles for the last time will be extended for another week until the end of July 3, 1402. It is obvious that this is the final opportunity and considering the short time until the day of the conference, after that it will not be possible to submit articles and also to modify the articles.
