Perhaps you should try some spelling variations:
surface diffusion » state diffusion
information line » information lines, information life, information online
array forming » array format, array arcing, array fermi
line surface » plane surface, spline surfaces, large surface
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 line surface diffusion ((((array using) OR (array string))) OR (array forming))~.
• Adding a wildcard symbol may retrieve word variants: information line surface diffusion ((((array using) or (array string))) or (array forming))*.
