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 spaces"
"advances in chemistry sources" » "advances in chemistry courses", "advances in chemistry surfaces", "advances in chemistry force"
"Advances in chemistry series" » "Advances in chemistry sars", "Advances in chemistry seeing", "Advances in chemistry semi"
"Advances in chemistry erich" » "Advances in chemistry metrics", "Advances in chemistry africa", "Advances in chemistry ethics"

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 series") OR ("Advances in chemistry erich"))) OR ("advances in chemistry studies"))) OR ("advances in chemistry species"))) OR ("advances in chemistry sources"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"Advances in chemistry series\") OR (\"Advances in chemistry erich\"))) or (\"advances in chemistry studies\"))) or (\"advances in chemistry species\"))) or (\"advances in chemistry sources\"))*".
• Removing quotes may allow a broader search: (((((((( Advances in chemistry series ) OR ( Advances in chemistry erich ))) or ( advances in chemistry studies ))) or ( advances in chemistry species ))) or ( advances in chemistry sources ))*.
