Perhaps you should try some spelling variations:
"advances in chemistry specimen" » "advances in chemistry species", "advances in chemistry sediment", "advances in chemistry special"
"advances in chemistry spaces" » "advances in chemistry space", "advances in chemistry species", "advances in chemistry snakes"
"Advances in chemistry simple" » "Advances in chemistry some", "Advances in chemistry space"
"Advances in chemistry self" » "Advances in chemistry solid", "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 spaces") OR ((("Advances in chemistry simple") OR ("Advances in chemistry self"))))) OR ("advances in chemistry specimen")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"advances in chemistry spaces\") or (((\"Advances in chemistry simple\") OR (\"Advances in chemistry self\"))))) or (\"advances in chemistry specimen\"))".
• Removing quotes may allow a broader search: (((( advances in chemistry spaces ) or ((( Advances in chemistry simple ) OR ( Advances in chemistry self ))))) or ( advances in chemistry specimen )).
• Adding a wildcard symbol may retrieve word variants: (((("advances in chemistry spaces") or ((("Advances in chemistry simple") OR ("Advances in chemistry self"))))) or ("advances in chemistry specimen"))*.
