Search engine optimization for scientific authors
As the ACS ads puts it, it is no longer sufficient to publish not to perish, your paper needs to be found. The good news is that scientific editors come to maximize the benefit we (and they) can get from search engine optimization for scientific papers.Check...

New article submitted
Aaaarrrrgggghhhhh…. I finally submitted that doomed paper to this high-impact factor physics journal. Took me a too long time to write it down, and to get it into the limited article length :o(( For those interested, here is the abstract : We resolve...
