Abstract
A method of forming particles comprises accelerating a stream comprising a liquid; and vibrating the stream, to form particles. The particle may have a diameter that is smaller than the diameter of the nozzle used to form the stream, allowing for the formation of micro- and nano-sized particle.
Claims62
A method of forming particles, comprising:
- accelerating a first stream comprising a first liquid;
- and
- vibrating the first stream, to form particles.
A method of forming particles, comprising:
- accelerating a first stream comprising a first liquid;
- wherein the accelerating comprises applying charge to the first stream, and
- the particles comprise a core and a shell.
Particles having an average diameter of 50 to 100 μm, wherein 90% of the particles have a diameter that is within 2% of an average diameter of the particles.
Particles having an average diameter of 1 to 50 μm, wherein 90% of the particles have a diameter that is within 1 μm of an average diameter of the particles.
An apparatus for forming particles, comprising:
- (i) a first nozzle, for forming a first stream of a first liquid,
- (ii) a second nozzle, oriented for forming a second stream of a second liquid in contact with the first stream, and
- (iii) a vibrator, for forming particles from the first stream.
An apparatus for forming particles, comprising:
- (i) a first nozzle, for forming a first stream of a first liquid,
- (ii) a charge source, for applying charge to the first stream, and
- (iii) a vibrator, for forming particles from the first stream.
An apparatus for forming particles, comprising:
- (i) means for forming a first stream of a first liquid,
- (ii) means for accelerating the first stream, and
- (iii) means for vibrating the first stream.
An apparatus for forming particles, comprising:
- (i) a first nozzle, for forming a first stream of a first liquid,
- (ii) a second nozzle surrounding the first nozzle, for forming a second stream of a second liquid surrounding the first stream,
- (iii) a charge source, for applying charge to at least one of the first and second streams.
