Perhaps you should try some spelling variations:
ionization instrumentation » operation instrumentation, radiation instrumentation, collection instrumentation
instrumentation emerging » instrumentation imaging, instrumentation generating, instrumentation energy
emerging dimensions » emerging directions, changing dimensions
image spaces » image space, image stacks, image states
gate » gave, game

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

• Performing a fuzzy search may retrieve terms with similar spellings: ionization instrumentation emerging dimensions ((image spaces) or (((gate OR gae) or gale) stacks))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ionization instrumentation emerging dimensions ((image spaces) OR (((gate OR gae) OR gale) stacks)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ionization instrumentation emerging dimensions ((image spaces) or (((gate OR gae) or gale) stacks))".
• Adding a wildcard symbol may retrieve word variants: ionization instrumentation emerging dimensions ((image spaces) or (((gate OR gae) or gale) stacks))*.
