Perhaps you should try some spelling variations:
surface diffusion » state diffusion
information it's » information its, information items, information ideas
array probing » arrays probing, assay probing, array profiling
it's surface » its surface, io's surface, e's surface
array string » array strong, arrays strings, array sharing
array arcing » array forming, array sharing, array 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 it's surface diffusion ((array string) OR (((array arcing) OR (array probing))))~.
• Adding a wildcard symbol may retrieve word variants: information it's surface diffusion ((array string) or (((array arcing) or (array probing))))*.
