Study on Dynamic Evolution and Erosion Characteristics of Cavitation Clouds in Submerged Cavitating Water Jets

Journal of Marine Science and Engineering
The dynamic evolution behavior of submerged water jet cavitation clouds was studied by combining experiments and simulation. The formation, development, shedding, and collapsing process of a void cloud was analyzed by high-speed camera technology, and ...

Study of a Frugal Design Picosecond Laser System for Laser‐Assisted Corneal Surgery

Journal of Biophotonics, Volume 19, Issue 10, October 2026.
Stromal surface after extraction of the lamella cut with the studied frugal picosecond laser source. ABSTRACT Femtosecond lasers have long been the gold standard for corneal laser‐assisted surgery, but their high cost limits widespread use. This study challenges their supremacy by investigating a cost‐effective alternative: a frugal all‐fiber ...

Driving Drugs Deeper: Force‐Driven Microneedle Systems for Active Therapy and Their Road Towards Clinical Implementation

Small, Volume 22, Issue 55, 1 October 2026.
Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

Enhancement of an aggressive intensity of a cavitating jet by water flow holes near nozzle outlet

Nihon Kikai Gakkai ronbunshu, 2019
The cavitation cloud generated by submerged high-speed water jet has periodicity. The periodicity is provided by alternately repeating the bubbles generation and shedding process and cavitation nucleus filling process.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, Volume 7, Issue 5, October 2026.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Mechanisms of Ultrasound‐Assisted In Situ Chemical Oxidation for Groundwater Remediation: A Laboratory‐Scale Column Study

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Groundwater contamination has become an increasingly critical environmental concern worldwide. In situ chemical oxidation (ISCO) is considered a promising technology for groundwater remediation, but its performance in heterogeneous aquifers is often constrained by mass‐transfer limitations in low‐permeability zones, leading to suboptimal ...

Cavitation Observations in a Jet-Flow Gate-Valve

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1984
As a step for clarification of the mechanism of cavitation erosion as well as noises at a jet-flow gate-valve, the cavitation-aspects and the associated sound-pressures were simultaneously observed systematically by means of high-speed-photography and sensitive pressure-detection through a hydrophone, in a 1/10-scale model-valve for various openings ...

Instantaneous Behavior of Cavitation Clouds at Impingement of Cavitating Water-Jet

Progress in Multiphase Flow Research, 2007
It is known that water-jet with cavitation clouds shows unsteady behavior and causes high impact. It is useful for not only the water jet technology but also various engineering fields. The unsteadiness of cavitation clouds is one of the most interesting problems for the use of the cavitating water-jet.
