Perhaps you should try some spelling variations:
"polymers science" » "polymers surface", "polymers spin", "polymer sequence"
"polymer sciene" » "polymer gene", "polymer size", "biopolymer science"
"polymer sphere" » "polymer spheres", "polymeric spheres", "polymer sheet"

Try widening your search to All Fields.

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: (((((((("polymer sciene") OR ("polymer sphere"))) OR ("polymers science"))) OR ("polymer science"))) OR ("polymer sciences")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((((\"polymer sciene\") OR (\"polymer sphere\"))) or (\"polymers science\"))) or (\"polymer science\"))) or (\"polymer sciences\"))".
• Removing quotes may allow a broader search: (((((((( polymer sciene ) OR ( polymer sphere ))) or ( polymers science ))) or ( polymer science ))) or ( polymer sciences )).
• Adding a wildcard symbol may retrieve word variants: (((((((("polymer sciene") OR ("polymer sphere"))) or ("polymers science"))) or ("polymer science"))) or ("polymer sciences"))*.
