Perhaps you should try some spelling variations:
vibrational properties » functional properties
additional properties » functional properties, medicinal properties
physical properties » optical properties, mechanical properties

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: ((((physical properties) OR (vibrational properties))) OR (additional properties)).
• Adding a wildcard symbol may retrieve word variants: ((((physical properties) or (vibrational properties))) or (additional properties))*.
