TL;DR: In this article, the authors present an apparatus and corresponding method for concentrating analytes within a fluid flowing through a tube using acoustic radiation pressure, which includes a function generator that outputs a radio frequency electrical signal to a transducer that transforms the radio frequency electric signal to an acoustic signal and couples the acoustic signal to the tube.

TL;DR: In this paper, the authors investigate the manipulation of 5 nm diamond nanoparticles in a user-defined pattern on a substrate using the acoustic radiation force associated with a bulk acoustic standing wave.

TL;DR: In this article, an apparatus for noninvasively monitoring the flow and/or the composition of a flowing liquid using ultrasound is described, where the position of the resonance peaks for a fluid excited by a swept-frequency ultrasonic signal have been found to change frequency both in response to a change in composition and in response in the flow velocity thereof.

TL;DR: In this paper, an apparatus and method for continuous and point level liquid level detection in a closed container or pipe having an inaccessible interior volume such that it is difficult to retrofit these tanks with a level gauge that operates within the storage volume.

TL;DR: In this article, a device, positioned within a well bore, configured to generate and direct an acoustic beam into a rock formation around a borehole, is described, where the transducer is coupled with a non-linear material, coupled to the source, to generate a collimated beam with a frequency equal to the difference between the first frequency and the second frequency by a nonlinear mixing process.
