Site for chemical journals from sciencedirect, springerlink, ACS

I need some chemical materials for my final project in university. And I've found several awesome sources providing those, those are sciencedirect, springerlink or ACS (American Chemical Society), but they're not free :( So I need your help to find out some sites which supply free downloading of those.

By the way, my project is about passive sampler and ozone.

so, you're going to be a dphil wasting your time on torrents? go out and PAY

I coulda helped you out but you are a leech,i don't like leeches.seems like you'll just have to go buy the books instead.
