Effects of air oversaturation and wettability on ultrasonication-generated surface microbubbles and their implications for froth flotation [PDF]

Ultrasonics Sonochemistry
Surface microbubbles generated during ultrasonic pretreatment can enhance froth flotation. However, the effective utilization of these microbubbles requires air-oversaturated conditions in the liquid after ultrasonication.

Microbubbles Reforming Endothelium

AIP Conference Proceedings, 2006
Ultrasound contrast microbubbles have the ability to enhance cell permeability and thus may be used as a new way to deliver drugs inter-vascular. It facilitates the transfer of extracellular molecules into cells through ultrasound-activated microbubbles.

DEVELOPMENT OF A FLUIDIC OSCILLATOR-DRIVEN FLOTATION SYSTEM [PDF]

, 2013
Treatment of liquid effluents is a serious challenge owing to the high stability and colloidal nature of the particles. In many applications, microbubbles (5 bars and consequently consuming ~90% of the total energy required in water purification plants ...

The Impact of Lipid Handling and Phase Distribution on the Acoustic Behavior of Microbubbles

Pharmaceutics, 2021
Phospholipid-coated microbubbles are ultrasound contrast agents that can be employed for ultrasound molecular imaging and drug delivery. For safe and effective implementation, microbubbles must respond uniformly and predictably to ultrasound.

Microbubble surface modes [PDF]

IEEE Ultrasonics Symposium, 2004, 2005
We have investigated surface vibrations generated by ultrasound excitation of individual unencapsulated micron-sized bubbles. In addition, we present surface modes (n=2 and 3) observed for phospholipid-coated ultrasound contrast agents excited through excitation of radial modes at frequencies between 1 and 4 MHz.

On the theory of multiple encapsulated microbubbles interaction: Effect of lipid shell thickness

Case Studies in Thermal Engineering, 2023
Encapsulated microbubbles are empty, micrometer-sized, spherical bubbles, typically micron which are used in many applications as lipid-shells in soft tissues.

Nonspherical ultrasound microbubbles

Proceedings of the National Academy of Sciences, 2023
Surface tension provides microbubbles (MB) with a perfect spherical shape. Here, we demonstrate that MB can be engineered to be nonspherical, endowing them with unique features for biomedical applications. Anisotropic MB were generated via one-dimensionally stretching spherical poly(butyl cyanoacrylate) MB above their glass transition temperature ...
