Perhaps you should try some spelling variations:
information rough » information through, information rugs, informatics rough
surface diffusion » state diffusion
rough surface » rough surfaces
array forming » array format, array arcing, array fermi
array string » array strong, arrays strings, array sharing
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 rough surface diffusion ((((array using) OR (array forming))) OR (array string))~.
• Adding a wildcard symbol may retrieve word variants: information rough surface diffusion ((((array using) or (array forming))) or (array string))*.
