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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"advances in chemistry species\\") or (\\"advances in ((chemistry specimen) OR (chemistry specific))\\"))\"".
• Removing quotes may allow a broader search: (( advances in chemistry species ) or ( advances in ((chemistry specimen) OR (chemistry specific)) )).
