Perhaps you should try some spelling variations:
"surfaces and interfaces, think films" » "surfaces and interfaces, thin films", "surfaces and interfaces, thick films", "surfaces and interfaces, think film"
"surfaces and interfaces, thin files" » "surfaces and interfaces, thin films", "surfaces and interfaces, thin fibers", "surfaces and interfaces, thin film"

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: "((\"surfaces and interfaces, thin files\") OR (\"surfaces and interfaces, think films\"))".
• Removing quotes may allow a broader search: (( surfaces and interfaces, thin files ) OR ( surfaces and interfaces, think films )).
• Adding a wildcard symbol may retrieve word variants: (("surfaces and interfaces, thin files") OR ("surfaces and interfaces, think films"))*.
