Mass transfer from freely rising microbubbles in aqueous solutions of surfactant or salt

, 2020
Microbubbles are used in many applications. One of the major advantages of using microbubbles is to improve the mass transfer of gases to the bulk phase.

Microbubble intensification of bioprocessing

2020
Microbubbles have been involved in industrial processing since the 1970s with the introduction of dissolved air flotation into common practice. The turn of the century saw microbubbles become regularly used in medical imaging. But in bioprocessing, only this decade has seen rapid advances in R&D, with some bioprocesses, particularly in wastewater ...

Interaction of Microbubbles with Ultrasound

Echocardiography, 1999
The clinical need for bedside myocardial perfusion studies is obvious in the present era of revascularization. Animal and first clinical studies suggest that microbubbles can be used as intravascular tracers of perfusion in conjunction with echocardiography as an imaging modality.

Microbubbles for Medical Applications

2014
Ultrasound contrast agent (UCA) suspensions contain encapsulated microbubbles with radii ranging from 1 to 10 micrometers. The bubbles oscillate to the driving ultrasound pulse generating harmonics of the driving ultrasound frequency. This feature allows for the discrimination of non-linear bubble echoes from linear tissue echoes facilitating the ...

The lung as a filter for microbubbles

Journal of Applied Physiology, 1979
A new ultrasonic Doppler device has been used noninvasively over the femoral artery of anesthetized dogs to prove that it can detect carefully calibrated microbubbles of 14--189 micrometers diam when these are infused directly into the aorta. The same evaluated technique has then been employed to detect any bubbles escaping into the arterial system ...

The bridging action of microbubbles in particle-bubble adhesion

, 2020
Microbubbles play an important role in the adhesion between particle and bubble. In this paper, the bridging action of microbubbles on the adhesion between particle and bubble was studied at different pre-wetting times in the sodium oleate system.

Ultrasound, microbubbles, and thrombolysis

Progress in Cardiovascular Diseases, 2001
Although dissolution of thrombus using ultrasound has been attempted for over 25 years, the clinical use of this technique remains limited. The ability of microbubbles to potentiate ultrasound-induced thrombolysis has renewed interest in this technique, which recanalizes occluded vessels without the need for fibrinolytic therapy.

Bulk Nanobubbles Fabricated by Repeated Compression of Microbubbles.

Langmuir, 2019
Nanobubbles (NBs), given its extraordinary properties, have drawn keen attention in the field of nanotechnology worldwide. However, compared to that of surface NBs, generation of stable bulk NBs remains an arduous task with the prevailing method. In this
