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"
"advances in chemistry sources" » "advances in chemistry courses", "advances in chemistry surfaces", "advances in chemistry force"

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"))) OR ("advances in chemistry sources"))*.
• 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\"))) or (\"advances in chemistry sources\"))*".
• Removing quotes may allow a broader search: (((((( Advances in chemistry studies ) OR ( Advances in chemistry study ))) or ( advances in chemistry species ))) or ( advances in chemistry sources ))*.
