Microbubble-enhanced dielectric barrier discharge pretreatment of microcrystalline cellulose [PDF]

open access: yes, 2018
Cellulose recalcitrance is one of the major barriers in converting renewable biomass to biofuels or useful chemicals. A pretreatment reactor that forms a dielectric barrier discharge plasma at the gas-liquid interface of the microbubbles has been ...

Cavitation Characterization of Size-Isolated Microbubbles in a Vessel Phantom Using Focused Ultrasound

open access: yesPharmaceutics, 2022
Pharmaceutical delivery can be noninvasively targeted on-demand by microbubble (MB) assisted focused ultrasound (FUS). Passive cavitation detection (PCD) has become a useful method to obtain real-time feedback on MB activity due to a FUS pulse.

Shrinking microbubbles with microfluidics: mathematical modelling to control microbubble sizes [PDF]

open access: yesSoft Matter, 2017
Microbubbles have applications in industry and life-sciences. In medicine, small encapsulated bubbles (< 10 μm) are desirable because of their utility in drug/oxygen delivery, sonoporation, and ultrasound diagnostics. While there are various techniques for generating microbubbles, microfluidic methods are distinguished due to their precise control ...

Investigating the significance of multiple scattering in ultrasound contrast agent particle populations

open access: yes, 2005
The majority of the existing models describing the behavior of microbubble ultrasound contrast agents consider single, isolated microbubbles suspended in infinite media.

High yielding microbubble production method [PDF]

open access: yes, 2016
Microfluidic approaches to microbubble production are generally disadvantaged by low yield and high susceptibility to (micro)channel blockages. This paper presents an alternative method of producing microbubbles of 2.6 μm mean diameter at concentrations ...
