Experimental study on the characteristics of microjets and shock waves of cavitation bubbles near elastic boundaries

Yanwei Zhai et al.

Summary: This paper studies the interaction between cavitation bubbles and different elastic boundaries from the perspective of microjets and shock waves. The elastic deformation characteristics of elastic materials under the penetration of microjets are found to be the main influencing factors of cavitation erosion.

Dynamics of cavitation bubbles near granular boundaries

A. B. Sieber et al.

Summary: In this study, the dynamics of a cavitation bubble near beds of sand with different grain sizes were investigated using high-speed imaging. The results show that compared to a rigid boundary, a granular boundary leads to shorter bubble lifetimes and reduced centroid displacements. The behavior of the bubble is almost independent of the sand granularity within a certain range, and the collapsing bubble can form micro-jets and granular jets.

The influence of inter-bubble spacing on the resonance response of ultrasound contrast agent microbubbles

Hossein Yusefi et al.

Summary: This research explores the mutual influence between neighboring microbubbles and studies the effect of inter-bubble distance on microbubble radial resonance response using a finite element model. The findings indicate that two equal-sized microbubbles lead to a decrease in frequency response and an increase in amplitude response, while two unequal-sized microbubbles show minimal changes in the larger bubble but significant changes in the smaller bubble, including an increase in frequency response and a decrease in amplitude response, with a secondary off-resonance peak when in very close proximity.

The Role of Cavitation in Energy Delivery and Stone Damage During Laser Lithotripsy

Derek S. Ho et al.

Summary: This study investigates the role of cavitation bubbles in energy delivery and stone damage during laser lithotripsy, finding that longer pulse durations result in higher energy delivery but smaller craters. Stones treated in water showed greater volume, wider yet shallower craters compared to those treated in air. The findings suggest that cavitation is a contributor to stone damage during laser lithotripsy.

Cavitation bubble dynamics in a vicinity of a thin membrane wetted by different fluids

Ziga Lokar et al.

Summary: Understanding and controlling the interaction of cavitation bubbles with nearby materials is crucial for optimizing various processes. Significant differences in bubble behavior were observed depending on the properties of the surrounding fluids, while the influence of membrane properties was less pronounced. This study highlights the importance of focusing on liquid properties rather than membrane mechanics in the optimization process.

Supersonic needle-jet generation with single cavitation bubbles

Fabian Reuter et al.

Summary: Researchers have successfully generated single laser-induced bubbles in an aqueous environment near a solid surface, leading to the formation of a needle jet that propagates at supersonic speeds exceeding 850m/s, an order of magnitude faster than regular jets observed in cavitation bubbles. This highly repeatable, localized flow phenomenon could be utilized for injection purposes or material processing, potentially generating significantly larger water hammer pressures.

Effects of surface tension on the Richtmyer-Meshkov instability in fully compressible and inviscid fluids

Kaitao Tang et al.

Summary: Numerical simulations were conducted to investigate the Richtmyer-Meshkov instability with surface tension, validating and bridging theoretical models across different growth regimes. Results showed good agreement with theoretical predictions in both linear and nonlinear growth regimes, and a heuristic criterion was defined to identify the transition between the two. This highlights the utility of the numerical method for compressible problems with surface tension and paves the way for further investigation into mixed compressible/incompressible problems.

Poroviscoelasticity and compression-softening of agarose hydrogels

Abderrahim Ed-Daoui et al.

Summary: This study investigates the mechanical response of agarose hydrogels under compression, revealing compressible behavior at low strain rates, a decrease in Poisson's ratio with slow compressive ramp, and a mechanical response in the linear regime dominated by the bending of semiflexible strands or stretching of the network at higher agarose concentration.

Femtosecond lasers for eye surgery applications: historical overview and modern low pulse energy concepts

Thomas Asshauer et al.

Summary: This review provides an overview of the historical development and modern applications of femtosecond lasers in ophthalmology, focusing on the optical concepts. The latest laser system concept involves low pulse energy and high pulse frequency, enabling precise cutting with minimal side effects. Femtosecond lasers have been widely used for refractive cornea surgery, therapeutic cornea procedures, and lens surgery, with new areas of ophthalmic application currently under development.

Ultrasound and Microbubbles for Targeted Drug Delivery to the Lung Endothelium in ARDS: Cellular Mechanisms and Therapeutic Opportunities

Rajiv Sanwal et al.

Summary: ARDS is a lung disease characterized by increased permeability of the alveolar-capillary membrane, resulting in pulmonary edema and severe hypoxemia. The use of thoracic ultrasound and microbubbles can deliver therapeutic cargo preferentially to severely injured areas of the lung. This technique has potential for both therapy and research in lung injury.
