Perhaps you should try some spelling variations:
chemistry special » chemistry social, chemistry chemical, chemistry second
chemistry section » chemistry education, chemistry social
chemistry space » chemistry some, chemistry simple
advances » advanced

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 special) OR (chemistry space))) OR (chemistry section)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "advances in ((((chemistry special) OR (chemistry space))) or (chemistry section))".
• Adding a wildcard symbol may retrieve word variants: advances in ((((chemistry special) OR (chemistry space))) or (chemistry section))*.
