Perhaps you should try some spelling variations:
surface diffusion » state diffusion
information act » information age, information a, information about
array string » array strong, arrays strings, array sharing
array arcing » array forming, array probing, array sharing
act surface » actin surface, bet surface, cut surface
array using » arrays using

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: information act surface diffusion ((array string) OR (((array using) OR (array arcing))))~.
• Adding a wildcard symbol may retrieve word variants: information act surface diffusion ((array string) or (((array using) or (array arcing))))*.
