Breaking the Rayleigh-Plateau instability limit using thermocavitation within a droplet [PDF]
, 2013 We report on the generation of liquid columns that extend far beyond the traditional Rayleigh-Plateau instability onset. The columns are driven by the acoustic pressure wave emitted after bubble collapse.

Influence of distribution parameters on acoustic radiation from bubble clusters
Ultrasonics SonochemistryCavitation noise is the major noise in underwater, and the study of acoustic radiation from bubble clusters is the primary means to reveal the mechanism of cavitation noise.

Identification of collapse patterns of cavitation bubbles close to a solid wall
EPJ Web of Conferences, 2013 The article describes different patterns of bubble deformation during the cavitation bubble collapse close to a solid wall for different bubble-wall distances. The bubble is generated by energy discharge in water.

Numerical study of the effect of liquid compressibility on acoustic droplet vaporization
Ultrasonics Sonochemistry, 2021 In acoustic droplet vaporization (ADV), a cavitated bubble grows and collapses depending on the pressure amplitude of the acoustic pulse. During the bubble collapse, the surrounding liquid is compressed to high pressure, and liquid compressibility can ...

Modeling bubble collapse anisotropy in complex geometries
Physical Review Fluids, 2022 A gas or vapor bubble collapsing in the vicinity of a rigid boundary displaces towards the boundary and produces a high-speed jet directed at the boundary. This behavior has been shown to be a function of the 'anisotropy' of the collapse, measured by a dimensionless representation of the Kelvin impulse known as the anisotropy parameter [Supponen et al.,

Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting
Advanced Functional Materials, EarlyView.A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Advanced Functional Materials, EarlyView.High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.

Collapse of an initially spherical vapor cavity in the neighborhood of a solid boundary [PDF]
, 1970 Vapor bubble collapse problems lacking spherical symmetry are solved here using a numerical method designed especially for these problems. Viscosity and compressibility in the liquid are neglected.

Rebounds of deformed cavitation bubbles
, 2018 Presented here are experiments clarifying how the deformation of cavitation bubbles affects their rebound. Rebound bubbles carry the remaining energy of a bubble following its initial collapse, which dissipates energy mainly through shock waves, jets ...
