Perhaps you should try some spelling variations:
chemistry specific » chemistry specificity, chemistry specimen, chemistry scientific
chemistry species » chemistry specimen, chemistry series, chemistry spaces
chemistry special » chemistry social, chemistry chemical, chemistry section

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 (chemistry special))\\") or (\\"advances in chemistry specific\\"))\"".
• Removing quotes may allow a broader search: (( advances in ((chemistry species) OR (chemistry special)) ) or ( advances in chemistry specific )).
