Sterilization of Biofilm in Foam Using a Single Cavitation Bubble [PDF]

MATEC Web of Conferences, 2020
This article presents the sterilization of bacteria using cavitation bubbles. Cavitation generated by ultrasound creates a cavitation cloud. Therefore is more advantageous to generate the cavitation bubbles by laser-induced breakdown, because it is ...

Heat transfer during cavitation bubble collapse

, 2016
Cavitation phenomenon has found various industrial applications. The collapse process of a cavitation bubble is extremely violent in its final stage and the gas within the bubble can become extraordinarily hot. This paper introduces a heat transfer model

Shockwaves from air bubbles within pits induced by nearby cavitation bubbles

Ultrasonics Sonochemistry
The cavitation intensity in near-boundary regions was significantly affected by the smoothness of boundaries. Micro pits on these boundaries may harbor smaller air bubbles or gas nuclei, and cavitation bubbles within cavitation clouds or cavitation ...

Mass transfer enhancement produced by laser induced cavitation

, 2006
A microelectrode is used to measure the mass transfer perturbation and characteristics during the growth and subsequent collapse of a single bubble (which, following its initial expansion, achieved a maximum radius, Rm, of not, vert, similar500–1000 ?m).

Culinary Chemistry as a Platform for Interfacial Materials Design

Advanced Materials Interfaces, EarlyView.
Culinary processes control interfaces through heating, shear, gelation, and molecular transport. This Review connects selected gastronomic examples with food‐derived nanomaterials, plasmonic sensing, anthocyanin photovoltaics, and intelligent packaging. Original agar‐based plasmonic films illustrate the proposed translation.

Bubble cloud-mediated cavitation for tumor mechanical ablation and effector immune cell deployment

Ultrasonics Sonochemistry
Histotripsy is a cavitation-based tumor ablation technology. To achieve precise cavitation-based ablation requires investigating the cavitation behavior of the bubble cloud and their impact on tumor tissue.

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

Advanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

Study on the Collapse Process of Cavitation Bubbles Near the Concave Wall by Lattice Boltzmann Method Pseudo-Potential Model

Energies, 2020
In this paper, the lattice Boltzmann pseudo-potential model coupled the Carnahan–Starling (C-S) equation of state and Li’s force scheme are used to study the collapse process of cavitation bubbles near the concave wall.
