Spatially optimized gene transfection by laser-induced breakdown of optically trapped nanoparticles [PDF]
, 2014 We demonstrate laser-induced breakdown of an optically trapped nanoparticle with a nanosecond laser pulse. Controllable cavitation within a microscope sample was achieved, generating shear stress to monolayers of live cells. This efficiently permeabilize

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

Molecular Simulation of MoS2 Exfoliation. [PDF]
, 2018 A wide variety of two-dimensional layered materials are synthesized by liquid-phase exfoliation. Here we examine exfoliation of MoS2 into nanosheets in a mixture of water and isopropanol (IPA) containing cavitation bubbles.

Asia-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 ...

The importance of (un)dissolved gases on early-stage cavitation dynamics within an acoustic field
Ultrasonics SonochemistryGas content strongly affects cavitation dynamics; however, most studies rely solely on dissolved gas measurements, overlooking the influence of undissolved bubbles. This study investigates their role by introducing air bubbles (

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study presents the design and construction of an experimental system for evaluating the thermal performance of heat pipes, using sintered‐wick heat pipes charged with CuO nanofluids. The device used in this study is a sintered‐wick heat pipe, in which the liquid return is driven by capillary forces within the porous wick structure.
