Perhaps you should try some spelling variations:
"advances in chemistry series" » "advances in chemistry species", "advances in chemistry sources", "advances in chemistry erich"
"advances in chemical studies" » "advances in biochemical studies", "advances in clinical studies", "advances in classical 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 studies") OR ("advances in chemical studies"))))) OR ("advances in chemistry study")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"advances in chemistry series\") or (((\"advances in chemistry studies\") OR (\"advances in chemical studies\"))))) or (\"advances in chemistry study\"))".
• Removing quotes may allow a broader search: (((( advances in chemistry series ) or ((( advances in chemistry studies ) OR ( advances in chemical studies ))))) or ( advances in chemistry study )).
• Adding a wildcard symbol may retrieve word variants: (((("advances in chemistry series") or ((("advances in chemistry studies") OR ("advances in chemical studies"))))) or ("advances in chemistry study"))*.
