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 ...

Robust spatially resolved pressure measurements using MRI with novel buoyant advection-free preparations of stable microbubbles in polysaccharide gels [PDF]
, 2008 MRI of fluids containing lipid coated microbubbles has been shown to be an effective tool for measuring the local fluid pressure. However, the intrinsically buoyant nature of these microbubbles precludes lengthy measurements due to their vertical ...

Microbubbles in Food Technology
Annual Review of Food Science and Technology, 2023 Microbubbles are largely unused in the food industry yet have promising capabilities as environmentally friendly cleaning and supporting agents within products and production lines due to their unique physical behaviors. Their small diameters increase their dispersion throughout liquid materials, promote reactivity because of their high specific ...

A Simulation for Detecting Nonlinear Echoes from Microbubbles Packets
Archives of Acoustics, 2014 This work presents a simulation of the response of packets of microbubbles in an ultrasonic pulse-echo scan line. Rayleigh-Plesset equation has been used to predict the echo from numerically obtained radial dynamics of microbubbles. Varying the number of

Separation of chemically modified carbon nanotubes by surfactant free microbubble generation
AIP Advances, 2020 Bubble separation is a widely used and effective method for separating solids from liquids. In this study, we propose a method to generate roughly ∼104 microbubbles/μl in an ethanol–water solution (surfactant-free) by subjecting the container of the ...
