Perhaps you should try some spelling variations:
surface diffusion » state diffusion
information type » information types, information time, deformation type
array sharing » arrays bearing, array imaging, way sharing
array probing » arrays probing, assay probing, array profiling
type surface » hyper surface, tube surface, shape surface
array string » array strong, arrays strings, array forming

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 type surface diffusion ((array string) OR (((array sharing) OR (array probing))))~.
• Adding a wildcard symbol may retrieve word variants: information type surface diffusion ((array string) or (((array sharing) or (array probing))))*.
