Polymer Mechanochemistry in Microbubbles
Advanced Materials, 2023 AbstractPolymer mechanochemistry is a promising technology to convert mechanical energy into chemical functionality by breaking covalent and supramolecular bonds site‐selectively. Yet, the mechanochemical reaction rates of covalent bonds in typically used ultrasonication setups lead to reasonable conversions only after comparably long sonication times.

Optical microbubble resonator [PDF]
Optics Letters, 2010 We develop a method for fabricating very small silica microbubbles having a micrometer-order wall thickness and demonstrate the first optical microbubble resonator. Our method is based on blowing a microbubble using stable radiative CO(2) laser heating rather than unstable convective heating in a flame or furnace.

Flotation of fine particles in the presence of combined microbubbles and conventional bubbles
, 2020 It is known that fine and ultrafine particles are difficult to float mainly due to their low collision efficiency with bubbles. In this paper, the effect of microbubble addition, on the recovery of fine quartz particles floated with conventional bubbles ...
