Figure 4. Oxygen delivery kinetics.
(a) Dissolved oxygen kinetics after the addition of oxygenated water, bare motor (with or without US), RBC-PFC (with or without US), Motor-PFC (with or without US) into deoxygenated water. The US field was applied at 6 V. (b) Time to reach kinetic equilibrium of each sample indicated in (a). (c) Dissolved oxygen levels within first 40 seconds of each sample indicated in (a). (d) Dissolved kinetics after the addition of Motor-PFC into deoxygenated water at different US voltages. (e) Time to reach kinetic equilibrium of each sample indicated in (d) at different US voltages. (f) Dissolved oxygen levels within first 40 second of each sample indicated in (d) at different US voltages. A constant US frequency of 2.66 MHz was used in all experiments.
