Water under tension, as can be found in several systems including tree vessels, is metastable. Cavitation can spontaneously occur, nucleating a bubble. We investigate the dynamics of spontaneous or triggered cavitation inside water filled microcavities of a hydrogel. Results show that a stable bubble is created in only a microsecond time scale, after transient oscillations. Then, a diffusion driven expansion leads to filling of the cavity. Analysis reveals that the nucleation of a bubble… 

Radiation dynamics of a cavitation bubble in a liquid-filled cavity surrounded by an elastic solid.

A specific cavitation phenomenon that occurs inside the stems of trees is modeled by taking into account acoustic waves produced by bubble oscillations, and radiation damping is found to be predominant in comparison with viscous damping, except for very small bubbles.

The fast dynamics of cavitation bubbles within water confined in elastic solids.

The dynamics of cavitation bubbles when the liquid is fully entrapped in an elastic solid is explored, using light scattering, laser strobe photography and high speed camera recordings to show unexpectedly fast bubble oscillations in volume.

Turning Drops into Bubbles: Cavitation by Vapor Diffusion through Elastic Networks.

The initial shrinkage as a classical diffusive process, while the sudden bubble growth and oscillations are described using an inertial-(visco)elastic model, in excellent agreement with the experiments.

Molecular mechanism for cavitation in water under tension

Comparison of the observed bubble dynamics to the predictions of the macroscopic Rayleigh–Plesset (RP) equation, augmented with thermal fluctuations, demonstrates that the growth of nanoscale bubbles is governed by viscous forces.

The detailed acoustic signature of a micro-confined cavitation bubble.

A novel experimental setup where a micrometric volume of water is confined by a hydrogel-based material and it is shown that, submerging the sample in a hypertonic solution, the water within the cavity is placed under tension and the acoustic emission produced by the resulting bubble nucleation is precisely detected.

Driving water cavitation in a hydrogel cavity.

An analysis of the factors allowing cavitation pressure to form inside the cavity is proposed, to allow for precise tuning of the key geometrical and material parameters.

Effect of entropy on the nucleation of cavitation bubbles in water under tension.

The entropy of bubbles in water is computed as a function of their volume over a wide range of tensions from free energy calculations and it is found that the bubble entropy is an important contribution to the free energy that significantly lowers the barrier to bubble nucleation, thereby facilitating cavitation.

Soft cavitation in colloidal droplets.

The results reveal an unexpected dependence with the particle size and with the size distribution of the colloidal particles, which could be eventually used to measure tensile strengths of particle solutions with accuracy.



Cavitation in trees

Cavitation pressure in water.

This work investigates the limiting mechanical tension (negative pressure) that liquid water can sustain before cavitation occurs, and describes the method which consists in focusing a high amplitude sound wave in the bulk liquid, away from any walls, to obtain highly reproducible results.

Cavitation and fracture behavior of polyacrylamide hydrogels

The mechanical properties of gels present qualitatively contradictory behavior; they are commonly soft but also notoriously brittle. We investigate the elasticity and fracture behavior of swollen

Microevaporators with accumulators for the screening of phase diagrams of aqueous solutions

We design near-autonomous microfluidic devices for concentrating aqueous solutions steadily over days in a very controlled manner. We combine suction pumps that drive the solution and concentrate it

The transpiration of water at negative pressures in a synthetic tree

The design and operation of a microfluidic system formed in a synthetic hydrogel captures the main attributes of transpiration in plants: transduction of subsaturation in the vapour phase of water into negative pressures in the liquid phase, stabilization and flow of liquid water at large negative pressures.

Stability limit of liquid water in metastable equilibrium with subsaturated vapors.

The limit of stability of liquid water--the degree of subsaturation at which the liquid cavitates--in this metastable state within microscale voids embedded in hydrogel membranes is presented, and the cause of the disparity between the observed and predicted stability limit is examined.

Optimal vein density in artificial and real leaves

Scaling relations for evaporatively driven flow through simple networks reveal basic design principles for the engineering of evaporation–permeation-driven devices, and highlight the role of physical constraints on the biological design of leaves.

Gravitational stability of suspensions of attractive colloidal particles.

The compressional modulus is measured for emulsion networks induced by depletion attraction and a model that quantitatively predicts their gravitational stability is presented, which determines the relationship between the strength of the depletion attractions and the magnitude of the compressionalModulus.

Spectrum of light scattered from a viscoelastic gel

We report measurements of the spectrum of light scattered from thermally excited displacement fluctuations in polyacrylamide gels. These measurements have been carried out on the polarized scattered

Cavitation Events in Thuja occidentalis L.? : Utrasonic Acoustic Emissions from the Sapwood Can Be Measured.

Strong circumstantial evidence indicates that the ultrasonic AE result from cavitation events because: (a) they occur only when the xylem pressure potential Psi(xp) is more negative than a threshold level of about -1 megapascal; (b) the rate of AE events increases as Psi(-xp) decreases and when the net rate of water loss increases; (c) the AE can be stopped by raising Psi (xp) above -1Megapascal.
