May 15th, 2007
Abstract:
Researchers, Steven Africk and Clark K. Colton from Prodyne Corp. and MIT have developed an ultrasonic method for measuring nanoparticle concentration that may be extended to measuring size distribution, particle size and compressibility.
The technique used is an UltraSonic Pulsed Doppler (USPD) technique that measures ultrasonic power backscattered from suspended particles.
The method uses a single transducer and can be applied to particles in suspension and contained within almost any container. Acoustic energy in the form of unltrasonic energy is narrowly introduced into the container. The acoustic energy can cause movement in the suspension and subsequent Doppler effect measurements can be used to determine particle properties. may be introduced to a focal zone and narrow band interrogating signals may be used. The acoustic energy may cause movement or streaming of the fluid or suspension. The acoustic streaming may allow a Doppler effect measurement without any other source of velocity.
