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