Optothermal shaping of lamb waves with square and spiral phase fronts

Romain Christophe Rémy Fleury, Janez Rus, Aleksi Antoine Bossart

We introduce a Lamb-wave medium with tunable propagation velocities, which are controlled by a two-dimensional heating pattern produced by a laser beam. We utilized it to demonstrate that waves in an appropriately designed medium can propagate in the form ...

Ultrasound inspection training system

Romain Christophe Rémy Fleury, Janez Rus

An ultrasound inspection training system comprising a test object (1), an ultrasound producing device (3) configured to generate ultrasonic signals in the test object and read ultrasonic response signals emitted from the test object, a property altering de ...

Design and fabrication of a vigorous "cavitation-on-a-chip" device with a multiple microchannel configuration

Luis Guillermo Villanueva Torrijo, Morteza Ghorbani, Merve Zuvin, Mohammad Jafarpour, Farzad Rokhsar Talabazar

Hydrodynamic cavitation is one of the major phase change phenomena and occurs with a sudden decrease in the local static pressure within a fluid. With the emergence of microelectromechanical systems (MEMS), high-speed microfluidic devices have attracted co ...

Phonon-Driven Selective Modulation of Exciton Oscillator Strengths in Anatase TiO2Nanoparticles

Majed Chergui, Edoardo Baldini, Enrico Pomarico, Thomas Charles Henry Rossi, Malte Oppermann, Tania Palmieri, Gerald Auböck

The way nuclear motion affects electronic responses has become a very hot topic in materials science. Coherent acoustic phonons can dynamically modify optical, magnetic, and mechanical properties at ultrasonic frequencies, with promising applications as se ...

Synergistic Coupling Between Electrochemical and Ultrasound Treatments for Organic Pollutant Degradation as a Function of the Electrode Material (IrO2 and BDD) and the Ultrasonic frequency (20 and 800 kHz)

César Pulgarin, Erika Herrera Calderon, Fernando Guzman Duque

Solutions of the organic pollutant model, Crystal Violet (CV), were subjected to ultrasonic, electrochemical treatment and its combination. Ultrasound was tested at two frequencies (20 kHz or 800 kHz) and 80 W in deionized water. After 120 min, 20 kHz cond ...
