Micro-bubble emission boiling with the cavitation bubble blow pit [PDF]

open access: yesScientific Reports, 2016
AbstractThe miniaturization boiling (micro-bubble emission boiling [MEB]) phenomenon, with a high heat removal capacity that contributes considerably to the cooling of the divertor of the nuclear fusion reactor, was discovered in the early 1980s. Extensive research on MEB has been performed since its discovery.

Planar laser induced fluorescence for temperature measurement of optical thermocavitation [PDF]

open access: yes, 2019
Pulsed laser-induced cavitation, has been the subject of many studies describing bubble growth, collapse and ensuing shock waves. To a lesser extent, hydrodynamics of continuous wave (CW) cavitation or thermocavitation have also been reported.

Eulerian-Lagrangian method for simulation of cloud cavitation [PDF]

open access: yes, 2017
We present a coupled Eulerian-Lagrangian method to simulate cloud cavitation in a compressible liquid. The method is designed to capture the strong, volumetric oscillations of each bubble and the bubble-scattered acoustics.

Activating a Metallization Switch for Record Hydrogen Evolution in Single‐Atom Modified Polar MOF Piezocatalysts

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Piezocatalytic hydrogen evolution enables the conversion of mechanical energy into chemical fuels, but its efficiency is constrained by a trade‐off between piezoelectric polarization and electronic conductivity. Strong piezoelectric polarization is essential for sufficient driving force, yet highly polar materials typically suffer from poor ...

Scaling laws for jets of single cavitation bubbles [PDF]

open access: yes, 2016
Fast liquid jets, called micro-jets, are produced within cavitation bubbles experiencing an aspherical collapse. Here we review micro-jets of different origins, scales and appearances, and propose a unified framework to describe their dynamics by using ...

Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

open access: yesAdvanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Cavitation from Stable Bubbles [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1971
It is desirable for both scientific and practical reasons to improve control of sonic cavitation. A problem in doing this is to provide gas bubbles in specified numbers, sizes, and configurations. Another is to prevent onset of chaotic surface waves with their associated complications.

Breaking the Rayleigh-Plateau instability limit using thermocavitation within a droplet [PDF]

open access: yes, 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.

Ultrasound Modulation of Visual Circuits in Mice Independent of Auditory Confound

open access: yesAdvanced Science, EarlyView.
In this study, Qiu et al. found that low‐intensity ultrasound can directly activate sparse ultrasound‐sensitive neurons (UNs) in the primary visual cortex (V1) of deafened mice. The proportion of these sparse UNs is pressure‐dependent. Furthermore, ultrasound modulates visual circuitry with distinct excitatory and inhibitory effects.
