Perhaps you should try some spelling variations:
chemistry chemical » chemistry physical, chemistry technical
chemistry specimen » chemistry species, chemistry sediment, chemistry specific
chemistry special » chemistry social, chemistry section, chemistry space

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