Perhaps you should try some spelling variations:
chemistry surfaces » chemistry surface, chemistry space
chemistry sources » chemistry courses, chemistry studies, chemistry force
chemistry current » chemistry recent
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 sources) OR (chemistry surfaces))) OR (chemistry current)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "advances in ((((chemistry sources) OR (chemistry surfaces))) or (chemistry current))".
• Adding a wildcard symbol may retrieve word variants: advances in ((((chemistry sources) OR (chemistry surfaces))) or (chemistry current))*.
