Perhaps you should try some spelling variations:
"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 studies"
"Advances in chemistry sars" » "Advances in chemistry spps", "Advances in chemistry sr", "Advances in chemistry star"
"Advances in chemistry sets" » "Advances in chemistry meets", "Advances in chemistry setac", "Advances in chemistry self"

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 sars") OR ("Advances in chemistry sets"))) 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 sars\") OR (\"Advances in chemistry sets\"))) or (\"advances in chemistry species\"))) or (\"advances in chemistry sources\"))".
• Removing quotes may allow a broader search: (((((( Advances in chemistry sars ) OR ( Advances in chemistry sets ))) or ( advances in chemistry species ))) or ( advances in chemistry sources )).
• Adding a wildcard symbol may retrieve word variants: (((((("Advances in chemistry sars") OR ("Advances in chemistry sets"))) or ("advances in chemistry species"))) or ("advances in chemistry sources"))*.
