Perhaps you should try some spelling variations:
"partially accelerated" » "partially correlated", "partially integrated", "naturally accelerate"
"particles accelerated" » "particles acceleration", "lattices accelerated", "particle acceleraton"
"particle accelerators" » "particle accelerate", "particle accelerating"

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: (("particle accelerator") OR ((("particle accelerators") OR ((("partially accelerated") OR ((("particles accelerated") OR ("particle acceleration")))))))).
• Removing quotes may allow a broader search: (( particle accelerator ) or ((( particle accelerators ) or ((( partially accelerated ) or ((( particles accelerated ) or ( particle acceleration )))))))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerator") or ((("particle accelerators") or ((("partially accelerated") or ((("particles accelerated") or ("particle acceleration"))))))))*.
