Perhaps you should try some spelling variations:
"particles acceleratedd" » "particles acceleration", "particle accelerators", "particle acceleration", "particles accelerationd", "partially acceleratedd", "lattices acceleratedd"
"particles accelerated" » "particles acceleration", "partially accelerated", "lattices accelerated"
"particle accelerator" » "particle accelerators", "particle acceleration"

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