Hi, I am looking for phd free scholarship for inorganic chemistry. Wher I can get? I prefer european countries. I live in iran.

Good luck with that as a PhD course is extremely expensive.

Not sure how it works in Europe, but in the US it is common for PhD students in science majors to work as Teaching Assistants (TAs) and/or with a faculty advisor on research projects that are funded by outside grants. The money you earn may be enough to offset tuition. If you are interested, you start by investigating which universities have programs that interest you, and then start inquiring how to go about applying for this.
