Perhaps you should try some spelling variations:
chemistry specimen » chemistry special, chemistry specific, chemistry experiment
chemistry sediment » chemistry experiment, chemistry experiments, chemistry department
chemistry species » chemistry special, chemistry series, chemistry specific
chemistry spaces » chemistry space, chemistry snakes, chemistry stacey

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 spaces ) OR ((( advances in ((chemistry specimen) OR (chemistry sediment)) ) OR ( advances in chemistry species )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( advances in chemistry spaces ) or ((( advances in ((chemistry specimen) OR (chemistry sediment)) ) or ( advances in chemistry species ))))".
• Adding a wildcard symbol may retrieve word variants: (( advances in chemistry spaces ) or ((( advances in ((chemistry specimen) OR (chemistry sediment)) ) or ( advances in chemistry species ))))*.
