Perhaps you should try some spelling variations:
chemistry specific » chemistry specificity, chemistry special, chemistry scientific
chemistry specimen » chemistry sediment, chemistry special, chemistry experiment
chemistry species » chemistry special, chemistry spaces, chemistry studies
chemistry series » chemistry studies, chemistry sources, chemistry erich

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: "((\"advances in ((chemistry species) OR (chemistry series))\") or (\"advances in ((chemistry specific) OR (chemistry specimen))\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"advances in ((chemistry species) or (chemistry series))\\") or (\\"advances in ((chemistry specific) OR (chemistry specimen))\\"))\"".
• Removing quotes may allow a broader search: (( advances in ((chemistry species) or (chemistry series)) ) or ( advances in ((chemistry specific) OR (chemistry specimen)) )).
