Perhaps you should try some spelling variations:
"Advances in chemistry studies" » "Advances in chemistry study", "Advances in chemical studies"
"advances in chemistry species" » "advances in chemistry specimen", "advances in chemistry special", "advances in chemistry series"

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 studies\") OR (\"advances in chemistry species\"))".
• Removing quotes may allow a broader search: (( Advances in chemistry studies ) OR ( advances in chemistry species )).
• Adding a wildcard symbol may retrieve word variants: (("Advances in chemistry studies") OR ("advances in chemistry species"))*.
