1. A method of forming nano-objects, the method comprising:

  • combining two or more liquid streams together such that the two or more liquid streams contact over spatial dimensions sufficient to form a composite liquid stream; and

    exposing at least a portion of the composite liquid stream to an electric force field sufficient to form a nano-sized cone jet that is fragmented and then the composite liquid stream is solidified to form the nano-objects, the nano-objects having a non-fibrous shape and comprising multiple phases and multiple chemically distinct exposed surface regions.
