Perhaps you should try some spelling variations:
surfaces diffusion » surface diffusion, surfaces dimension, stresses diffusion
information gaps » information gap, information games, information gain
gaps surfaces » gaas surfaces, graphs surfaces, glass surfaces
array probing » arrays probing, assay probing, array profiling
array arcing » array forming, array sharing, array using
arrays long » arrays ang, arrays load, array along

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: information gaps surfaces diffusion ((arrays long) OR (((array arcing) OR (array probing))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "information gaps surfaces diffusion ((arrays long) OR (((array arcing) OR (array probing))))".
• Adding a wildcard symbol may retrieve word variants: information gaps surfaces diffusion ((arrays long) OR (((array arcing) OR (array probing))))*.
