Perhaps you should try some spelling variations:
chemistry specimen » chemistry sediment, chemistry special, chemistry specific
chemistry species » chemistry special, chemistry spaces, chemistry specific
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 series ) OR ( advances in ((chemistry species) OR (chemistry specimen)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( advances in chemistry series ) or ( advances in ((chemistry species) OR (chemistry specimen)) ))".
• Adding a wildcard symbol may retrieve word variants: (( advances in chemistry series ) or ( advances in ((chemistry species) OR (chemistry specimen)) ))*.
