While we certainly welcome experts to make contributions in their areas of expertise, I notice that all your edits involve rapidly adding a paper by Al-Tarawni to multiple articles. In general, this is inappropriate and is often considered spamming. It certainly looks like your only purpose here is self-promotion. Please have a look at Wikipedia's conflict of interest guidelines at Conflict of interest. Kind regards. ChemNerd (talk) 21:24, 13 February 2019 (UTC)
