Acknowledgment to friend in research article I have a research article that has been accepted in reputed journal and is in final stage of publication. Now I want add acknowledgment in my article, as I independently written this article so nobody has academically contributed to my research. But I strongly believe that my research could been effected very badly if my close friend had not been there for my help(not academic of-course).

Can I add his name in acknowledgment?
This sort of thing is quite normal in books. In articles, one frequently sees the author(s) thanking a colleague for fruitful discussions and such. If you really feel so strongly about your friend's impact on your work, I think it would be perfectly appropriate to include it. Just avoid specifics such as "X helped me deal with the effects of my depression and drug dependency". (In other words, use common sense.)
