Perhaps you should try some spelling variations:
surfaces diffusion » surface diffusion, surfaces dimension, stresses diffusion
information gels » information geo's, information gaps, information gis
gels surfaces » des surfaces, gaas surfaces, les surfaces
array probing » arrays probing, assay probing, array profiling
array paving » array planning, array imaging, 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 gels surfaces diffusion ((array paving) OR (((array using) OR (array probing))))~.
• Adding a wildcard symbol may retrieve word variants: information gels surfaces diffusion ((array paving) or (((array using) or (array probing))))*.
