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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( advances in chemistry species ) OR ((( advances in chemistry specimen ) OR ((( Advances in chemistry specific ) OR ( Advances in history specific )))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( advances in chemistry species ) or ((( advances in chemistry specimen ) or ((( Advances in chemistry specific ) OR ( Advances in history specific ))))))".
• Adding a wildcard symbol may retrieve word variants: (( advances in chemistry species ) or ((( advances in chemistry specimen ) or ((( Advances in chemistry specific ) OR ( Advances in history specific ))))))*.
