Perhaps you should try some spelling variations:
"Advances in chemistry studies" » "Advances in chemical studies"
"advances in chemistry species" » "advances in chemistry specimen", "advances in chemistry special", "advances in chemistry series"

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