Perhaps you should try some spelling variations:
"advances in chemistry species" » "advances in chemistry specimen", "advances in chemistry special", "advances in chemistry spaces"
"advances in chemistry series" » "advances in chemistry studies", "advances in chemistry sources", "advances in chemistry erich"
"advances in chemistry optics" » "advances in chemistry topics", "advances in chemistry metrics", "advances in chemistry basics"
"advances in chemistry simple" » "advances in chemistry some", "advances in chemistry self"
"advances in chemistry space" » "advances in chemistry some"

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