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

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