Perhaps you should try some spelling variations:
"advances in chemistry sources" » "advances in chemistry courses", "advances in chemistry surfaces", "advances in chemistry studies"
"advances in chemistry series" » "advances in chemistry species", "advances in chemistry studies", "advances in chemistry erich"
"advances in chemical studies" » "advances in biochemical studies", "advances in classical studies", "advances in biblical studies"
"advances in clinical studies" » "advances in empirical studies"

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 study") OR ((("advances in chemical studies") OR ("advances in clinical studies"))))))) OR ("advances in chemistry sources")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"advances in chemistry series\") or (((\"advances in chemistry study\") or (((\"advances in chemical studies\") OR (\"advances in clinical studies\"))))))) or (\"advances in chemistry sources\"))".
• Removing quotes may allow a broader search: (((( advances in chemistry series ) or ((( advances in chemistry study ) or ((( advances in chemical studies ) OR ( advances in clinical studies ))))))) or ( advances in chemistry sources )).
• Adding a wildcard symbol may retrieve word variants: (((("advances in chemistry series") or ((("advances in chemistry study") or ((("advances in chemical studies") OR ("advances in clinical studies"))))))) or ("advances in chemistry sources"))*.
