Perhaps you should try some spelling variations:
informatics rough » information rough, bioinformatics rough, informatics group
state diffusion » surface diffusion
array forming » array format, array arcing, array fermi
array string » array strong, arrays strings, array sharing
rough state » through state, through stat
array using » arrays using

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "informatics rough state diffusion ((((array using) OR (array forming))) OR (array string))~".
• Adding a wildcard symbol may retrieve word variants: informatics rough state diffusion ((((array using) OR (array forming))) OR (array string))*.
