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"

You may be able to get more results by adjusting your search query.

• 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"))))*.
