I am interested in this paper An Evaluation of the Potential of NMR Spectroscopy and Computational Modelling Methods to Inform Biopharmaceutical Formulations. But it seems that it could not be found on Google Scholar. Can I ask why?
That paper was published on Friday 21 September 2018. You're asking this question on Sunday 23 September 2018... In my experience it usually takes a week or longer for Google Scholar to index a paper, depending on the journal. Also see How long does it usually take for published articles to show up on Google Scholar? for more information on the variability. The bottom line is that papers don't show up on Google Scholar the instant they are published, so be patient or use other ways of accessing it.
