Abstract:
Acoustic energy is used to control motion in a fluid. According to one embodiment, the invention directs acoustic energy at selected naturally occurring nucleation features to control motion in the fluid. In another embodiment, the invention provides focussed or unfocussed acoustic energy to selectively placed nucleation features to control fluid motion. According to one embodiment, the invention includes an acoustic source, a controller for controlling operation of the acoustic source, and one or more nucleation features located proximate to or in the fluid to be controlled.

Abstract:
Apparatus and methods are disclosed for treating a sample by selectively controlling sonic energy and/or selectively controlling the location of the sample relative to the sonic energy.
Abstract:
Method and apparatus for controlling acoustic treatment of a sample including a liquid. A processing volume in which the sample is acoustically treated may be controlled, e.g., by positioning a suitable element so as to reduce and/or eliminate a headspace at a sample/gas interface. An interaction between the acoustic energy and the sample may be controlled, e.g., by using an energy director positioned at least partially in the sample that helps to reduce splashing or other sample ejection that would otherwise occur.

Abstract:
The invention, in various embodiments, provides systems, methods and devices relating to processing a sample. A vessel is described for containing a sample. The vessel includes a reversibly sealable chamber for containing the sample which has a flexible portion to allow the vessel to deform nondestructively in response to a mechanical impact to fragment the sample. In certain embodiments the vessel may include a port for reversibly engaging with a second vessel to enable transfer of material between the two vessels while maintaining a barrier between the sample and an external environment. The vessel may be exposed to mechanical impacts of various energies and at various temperatures, and the internal surface of the structural barrier of the vessel may be treated with various chemical agents to maintain integrity of the sample.

Abstract:
The invention is based on the discovery that biological and non-biological materials can be sterilized, decontaminated, or disinfected by repeatedly cycling between relatively high and low pressures. Pressure cycling can be carried out at low, ambient, or elevated temperatures (e.g., from about −40° C. to about 95° C., or intermediate ranges). New methods based on this discovery can have applications in, for example, the preparation of vaccines, the sterilization of blood plasma or serum, plant, animal, and human tissue, sputum, urine, feces, water, and ascites, the decontamination of military devices, food and beverage production, and the disinfection of medical equipment. The new methods can also be incorporated into production processes or research procedures.
