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 surfaces", "advances in chemistry force", "advances in chemistry some"
"advances in chemistry courses" » "advances in chemistry current"
"advances in chemistry studies" » "advances in chemistry study", "advances in chemical studies"

Try widening your search to All Fields.

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