Sono‐Mechanogenetics: Linking Ultrasound Physics With Cellular Mechanobiology

open access: yesAdvanced Science, EarlyView.
Sono‐mechanogenetics links ultrasound physics with cellular mechanotransduction to enable noninvasive control of engineered biological systems. Acoustic forces generate distinct deformation modes that activate intracellular signaling pathways, which can be coupled to synthetic gene circuits to regulate diverse cellular functions, including gene ...

A new cavitation model considering inter-bubble action

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2021
The process of cavitation involves generation, growth, coalescence, and collapse of small bubbles and is tremendously influenced by bubble–bubble interactions.

Particle Motion Induced by Bubble Cavitation

open access: yesPhysical Review Letters, 2015
Cavitation bubbles induce impulsive forces on surrounding substrates, particles, or surfaces. Even though cavitation is a traditional topic in fluid mechanics, current understanding and studies do not capture the effect of cavitation on suspended objects in fluids.

Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

open access: yesAdvanced Science, EarlyView.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

open access: yesAdvanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Growth and Collapse of Cavitation Bubbles : Distribution Change of Cavitation Nuclei due to the Collapse of Cavitation Bubbles

open access: yesBulletin of JSME, 1984
The growth and collapse of cavitation bubbles are observed in distilled water using a hydro shock tube which alternately generates low The cavitation bubbles pressure and high pressure in the test section. are fragmentized into numerous small bubbles (so called nuclei) after their collapse.

Ultrasound–Calcination Synergistic Control of (Ce, La)PO4 Catalyst Structure for Enhanced Low‐Temperature NH3‐SCR Performance

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, (Ce, La)PO4 catalysts were synthesized via an ultrasound‐assisted method. The effects of ultrasound duration and calcination temperature on the low‐temperature NH3‐SCR performance were systematically investigated. The results indicated that the (Ce, La)PO4 catalyst prepared with an ultrasound treatment time of 20 min and a ...

Study on the coupling characteristics of different numbers of cavitation bubbles and particle groups in the free domain

open access: yesUltrasonics Sonochemistry
In a free field multiphase environment, the coupling between cavitation bubble dynamics and particle groups can markedly reshape local flow structures and thereby influence particle impact risks.
