Perhaps you should try some spelling variations:
"particles interconnection" » "parallel interconnection", "partial interconnections", "particles introduction"
"optimal interconnections" » "optical interconnections", "optimal interconnection", "optical interconnection"
"partial interconnection" » "partial interconnections", "vertical interconnection", "spiritual interconnection"
"particles interaction" » "particle interaction", "particle interactions", "particles interacting"

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: (((("optimal interconnections") OR ((("particles interconnection") OR ("particles interaction"))))) OR ("partial interconnection")).
• Removing quotes may allow a broader search: (((( optimal interconnections ) or ((( particles interconnection ) or ( particles interaction ))))) or ( partial interconnection )).
• Adding a wildcard symbol may retrieve word variants: (((("optimal interconnections") or ((("particles interconnection") or ("particles interaction"))))) or ("partial interconnection"))*.
