Perhaps you should try some spelling variations:
"advances in chemistry specimen" » "advances in chemistry species", "advances in chemistry special", "advances in chemistry experiment"
"advances in chemistry sediment" » "advances in chemistry experiment", "advances in chemistry experiments", "advances in chemistry department"
"advances in chemistry specific" » "advances in chemistry specificity", "advances in chemistry special", "advances in chemistry species"
"advances in chemistry spaces" » "advances in chemistry space", "advances in chemistry species", "advances in chemistry snakes"

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