Figure S-1: (a) Current and voltage time dependence (over a 10 ms period) of the plasma discharge, measured using a Tektronix P3010 voltage probe and TCP202 current probe. The voltage between the anode and cathode was constant at 55 V, and the upper electrode current limit was set at 3.0 A throughout the experiment; (b) Digital image of the ultrasonic cavitation field beneath the bottom of the ultrasonic horn with an Fe tip; (c), (d), (e) Digital images of plasma discharge at 0.5, 2.5 and 4.5 ms after starting discharge, respectively; (e) Termination of plasma discharge due to increased distance between the anode and cathode. Digital images were recorded by high speed video camera FASTCAM-512PCI, at (b) 500 and (c)-(e) 2000 frames per second.

Figure S-2: (a) SEM and (c) TEM images of RGO sheets. High-resolution (b) SEM and (d) TEM images of individual RGO sheets. The sheets exhibit a crumpled structure.

Figure S-3: (a) TEM image of a FePt@CNC. HR-TEM images of (b) graphene layers in the FePt@CNC shell marked in (a), and (c) carbon onions (Mykhaylyk et al. 2005).
