Crystal Nucleation by Laser-Induced Cavitation\ud [PDF]

, 2011
High-speed and high-resolution photography have been used to investigate the relationship between creation, expansion, and collapse of a vapor cavity induced by a 6 ns laser pulse and the subsequent nucleation of crystals.

Tree shrew model of early diabetic retinopathy reveals microvascular dysfunction and identifies phosphoserine aminotransferase 1 as a novel therapeutic target

Animal Models and Experimental Medicine, EarlyView.
We developed an animal model of early diabetic retinopathy (DR) in the tree shrew by feeding a high‐fat and high‐sugar diet in combination with STZ. Physiological and biochemical index detection, hematoxylin and eosin staining, and transmission electron microscopy were performed to examine DR.

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.

Rebounds of deformed cavitation bubbles

, 2018
Presented here are experiments clarifying how the deformation of cavitation bubbles affects their rebound. Rebound bubbles carry the remaining energy of a bubble following its initial collapse, which dissipates energy mainly through shock waves, jets ...

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

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 ...

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine

BMEMat, EarlyView.
Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

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.

A Review of Cavitation Uses and Problems in Medicine; Invited Lecture [PDF]

, 2006
There are an increasing number of biological and bioengineering contexts in which cavitation is either utilized to create some desired effect or occurs as a byproduct of some other process.

Dynamics of bubble absorption over porous membranes in an immersed medium

Droplet, EarlyView.
The dynamics of a bubble interacting with a flat, porous superhydrophobic membrane underwater has been illustrated. Abstract Porous superhydrophobic (SHP) membranes are gaining considerable attention due to their excellent underwater absorption and drag reduction properties. They exploit the Cassie‒Baxter state of wetting to remove the bubble in a fast

Recent advances in boosting interfacial bubble dynamics with external fields

Droplet, EarlyView.
External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...
