Perhaps you should try some spelling variations:
"particles interconnection" » "partial interconnection", "parallel interconnection", "particles introduction"
"partial interconnections" » "partial interconnection", "optical interconnections", "mail interconnections"
"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: (((("particles interconnection") OR ("particles interaction"))) OR ("partial interconnections")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"particles interconnection\") OR (\"particles interaction\"))) or (\"partial interconnections\"))".
• Removing quotes may allow a broader search: (((( particles interconnection ) OR ( particles interaction ))) or ( partial interconnections )).
• Adding a wildcard symbol may retrieve word variants: (((("particles interconnection") OR ("particles interaction"))) or ("partial interconnections"))*.
