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 simples" » "Advances in chemistry simple", "Advances in chemistry examples", "Advances in chemistry complex"
"Advances in chemistry spaces" » "Advances in chemistry species", "Advances in chemistry snakes", "Advances in chemistry stacey", "Advances in chemistry somes", "Advances in chemistry simples"
"advances in chemistry space" » "advances in chemistry some", "advances in chemistry simple"

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 simples"))) OR ("advances in chemistry space"))) 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 simples\"))) or (\"advances in chemistry space\"))) or (\"advances in chemistry specimen\"))".
• Removing quotes may allow a broader search: (((((( Advances in chemistry spaces ) OR ( Advances in chemistry simples ))) or ( advances in chemistry space ))) or ( advances in chemistry specimen )).
• Adding a wildcard symbol may retrieve word variants: (((((("Advances in chemistry spaces") OR ("Advances in chemistry simples"))) or ("advances in chemistry space"))) or ("advances in chemistry specimen"))*.
