Channel‐trap coupled charge modulation in sulfur‐vacancy‐rich nanotransducer for enhanced dual‐mode cancer catalytic therapy

BMEMat, EarlyView.
Sulfur vacancy‐rich ZnS–NCx heterojunctions are engineered as dual‐function nanotransducers, in which channel‐trap‐coupled electronic pathways enable efficient capture and transport of ultrasound‐induced piezoelectrons. This vacancy‐mediated regulation simultaneously enhances sonodynamic activity and biomimetic POD/GSHOx catalysis, triggering a self ...

Analysis of radial oscillations of gas bubbles in Newtonian or viscoelastic mediums under acoustic excitation [PDF]

Acoustic cavitation plays an important role in a broad range of biomedical, chemical and oceanic engineering problems. For example, kidney stone can be crushed into the powder (being discharged naturally) by the acoustic cavitation generated by carefully

Acoustic cavitation and bubble dynamics

Archives of Acoustics, 2008
Acoustic cavitation is investigated experimentally and theoretically starting with a single bubble in an acoustic field. The single bubble is trapped in an acoustic resonator and observed by high-speed imaging and acoustic measurements following its transient dynamics to a possible steady state after generation by laser light.

Acoustic cavitation, bubble dynamics and sonoluminescence

Ultrasonics Sonochemistry, 2007
Basic facts on the dynamics of bubbles in water are presented. Measurements on the free and forced radial oscillations of single spherical bubbles and their acoustic (shock waves) and optic (luminescence) emissions are given in photographic series and diagrams.

Polarization‐Reoriented Piezocatalysis Enables Plastic Upcycling with Mechanical Energy

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mixed plastic waste remains difficult to upcycle selectively under mild conditions, and piezocatalysis has been constrained by a persistent see‐saw effect: Stronger piezoelectric polarization tends to divert charge carriers away from the very active sites that drive catalysis. Sha et al.

Origin of broadband acoustic emission from a dancing cavitation bubble

Applied Physics Express
Acoustic cavitation generates bubbles exhibiting violent expansion and contraction under intense ultrasound in liquids. The acoustic emissions (AE) spectrum from cavitation bubbles contains harmonics, subharmonics, ultraharmonics, and broadband noise ...
