Mg-Based Micromotors with Motion Responsive to Dual Stimuli

Figure 6

The normalized O2 concentration distribution around the Mg-based micromotor at (a) 22°C in 0.1 wt% H2O2, (b) 38°C in 0.1 wt% H2O2, and (c) 38°C in 0.8 wt% H2O2 aqueous solution. The right panels show the curves of theoretical O2 concentration on AA line segments within 20 ms versus the distance apart from the center of Mg core at different time intervals. The critical nucleation concentration of O2 bubble is 68 mM.
