Thermocavitation in gold-coated microchannels for needle-free jet injection
Jelle J. Schoppink, Nicolás Rivera Bueno, David Fernandez Rivas
Continuous-wave lasers generated bubbles in microfluidic channels are proposed for applications such as needle-free jet injection due to their small size and affordable price of th…
Bubble collapse near porous plates
Elijah D. Andrews, David Fernández Rivas, Ivo R. Peters
The collapse of a gas or vapour bubble near a non-porous boundary is directed at the boundary due to the asymmetry induced by the nearby boundary. High surface pressure and shear s…
Cavity dynamics after the injection of a microfluidic jet in capillary bridges
Miguel A. Quetzeri-Santiago, David Fernandez Rivas
The impact of solid and liquid objects (projectiles) onto liquids and soft solids (targets) generally results on the creation and expansion of an air cavity inside the impacted obj…
Microuidics control the ballistic energy of thermocavitation liquid jets for needle-free injections
Loreto Oyarte Galvez, Arjan Fraters, Herman L. Offerhaus +3
Illuminating a water solution with a focused continuous wave laser produces a strong local heating of the liquid that leads to the nucleation of bubbles, also known as thermocavita…
High speed imaging of solid needle and liquid micro-jet injections
Loreto Oyarte-Gálvez, Maria Brió Pérez, David Fernández Rivas
High speed imaging was used to capture the fast dynamics of two injection methods. The first one and perhaps the oldest known, is based on solid needles and used for dermal pigment…
Interacting bubble clouds and their sonochemical production
Laura Stricker, Benjamin Dollet, David Fernandez Rivas +1
Acoustically driven air pockets trapped in artificial crevices on a sur- face can emit bubbles which organize in (interacting) bubble clusters. With increasing driving power Fernan…
Efficient Sonochemistry through Microbubbles Generated with Micromachined Surfaces
David Fernandez Rivas, Andrea Prosperetti, Aaldert G. Zijlstra +2
Sonochemical reactors are used in water treatment, the synthesis of fine chemicals, pharmaceutics and others. The low efficiency of sonoreactors have prevented its massive usage at…
Sonoluminescence and sonochemiluminescence from a microreactor
David Fernandez Rivas, Muthupandian Ashokkumar, Thomas Leong +5
Micromachined pits on a substrate can be used to nucleate and stabilize microbubbles in a liquid exposed to an ultrasonic field. Under suitable conditions, the collapse of these bu…
