Perhaps you should try some spelling variations:
chemistry specificity » chemical specificity, chemistry electricity, industry specificity
chemistry specific » chemistry species, chemistry specimen, chemistry scientific
chemistry studies » chemistry study, chemical studies
chemistry special » chemistry social, chemistry chemical, chemistry section
chemistry series » chemistry species, chemistry sources, chemistry sars
chemistry erich » chemistry metrics, chemistry africa, chemistry ethics

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 (chemistry studies)) ) OR ( advances in chemistry erich ))) OR ( advances in ((((chemistry specific) OR (chemistry specificity))) OR (chemistry special)) )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( advances in ((chemistry series) or (chemistry studies)) ) or ( advances in chemistry erich ))) or ( advances in ((((chemistry specific) OR (chemistry specificity))) or (chemistry special)) ))".
• Adding a wildcard symbol may retrieve word variants: (((( advances in ((chemistry series) or (chemistry studies)) ) or ( advances in chemistry erich ))) or ( advances in ((((chemistry specific) OR (chemistry specificity))) or (chemistry special)) ))*.
