A method for achieving a desired state of fluidization of a sample, comprising:
- providing a focused acoustic field to a sample, the focused acoustic field having a frequency of between about 100 kilohertz and about 100 megahertz and a focal zone having a diameter of less than about 2 centimeters;
- monitoring emissions of acoustic energy from the sample;
- determining the state of fluidization of the sample based, at least in part, on the emissions of acoustic energy from the sample;
- and
- providing a modified focused acoustic field to the sample, the modified focused acoustic field having acoustic wave variables selected, at least in part, based on the determined state of fluidization to achieve the desired state of fluidization of the sample, wherein the selected acoustic wave variables include a frequency of between about 100 kilohertz and about 100 megahertz and a focal zone having a diameter of less than about 2 centimeters.

A method for achieving a desired state of mixing of a sample with a constituent comprising:
- providing a focused acoustic field to a sample, the focused acoustic field having a frequency of between about 100 kilohertz and about 100 megahertz and a focal zone having a diameter of less than about 2 centimeters;
- monitoring acoustic energy from the sample;
- determining the state of mixing of the sample with the constituent based, at least in part, on the acoustic energy from the sample;
- and
- providing a modified focused acoustic field to the sample, the modified focused acoustic field having acoustic wave variables selected, at least in part, based on the determined state of mixing to achieve the desired state of mixing of the sample, wherein the selected acoustic wave variables include a frequency of between about 100 kilohertz and about 100 megahertz and a focal zone having a diameter of less than about 2 centimeters.
