Suppressing the jet formation in a bubble pair excited with an ultrasonic pulse

Ultrasonics Sonochemistry
This study numerically explores the suppression of bubble jet formation in oscillating microbubble pairs under excitation with an ultrasonic pulse, focusing on the conditions that lead to bubble collapse without jetting.

Intensification of the Near Wall Collapsing Bubble Induced Jet Using an Opposite Secondary Wall

Journal of Fluid Science and Technology, 2008
Effects of an opposite secondary wall for intensification of the liquid jet that is formed through the near wall bubble collapse were numerically investigated. The axisymmetric form of the Navier-Stokes equations was solved to predict the flow conditions

Bubbling of Ferrofluid Droplets via Coupled Magnetic and Sound Fields

Advanced Materials Interfaces, 2023
Bubbles play essential roles in many natural and industrial processes because of the unique effects of their films on heat–mass transfer and their soft confined geometry for interfacial assembly or phase transitions.

Bubble Formation in ITER-Grade Tungsten after Exposure to Stationary D/He Plasma and ELM-like Thermal Shocks

Journal of Nuclear Engineering, 2023
Plasma-facing materials (PFMs) in the ITER divertor will be exposed to severe conditions, including exposure to transient heat loads from edge-localized modes (ELMs) and to plasma particles and neutrons.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Micro-jet formation induced by the interaction of a spherical and toroidal cavitation bubble

Ultrasonics Sonochemistry
We investigate experimentally and numerically the interaction between a spherical cavitation bubble and a wall-bounded toroidal cavitation bubble. We demonstrate that shock wave focusing following toroidal bubble initiation induces the formation of micro-
