Perhaps you should try some spelling variations:
chemistry specificity » chemical specificity, chemistry electricity, industry specificity
chemistry experiment » chemistry experiments, chemistry experimental, chemistry department
chemistry specific » chemistry special, chemistry specimen, chemistry scientific
chemistry species » chemistry specimen, chemistry special, chemistry series

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