Ultrasonic metamaterial at MHz frequencies using microstructured glass
Oscar Demeulenaere, Nikita Ustimenko, Athanasios G. Athanassiadis +3
Acoustic metamaterials enhance traditional material properties through microstructure engineering, providing new opportunities to shape sound fields in applications ranging from bi…
Spatially Selective Acoustic Pressure Reporting Using Antibubbles
Nicolas Moreno Gomez, Athanasios G. Athanassiadis, Fabian Reuter +5
Ultrasound offers promising applications in biology and chemistry, but quantifying local ultrasound conditions remains challenging due to the lack of non-invasive measurement tools…
Strain stiffening due to stretching of entangled particles in random packings of granular materials
Eric Brown, Kevin A. Mitchell, Alice Nasto +2
Stress-strain relations for random packings of entangling chains under triaxial compression can exhibit strain stiffening and sustain stresses several orders-of-magnitude beyond ty…
Technical Design Report for the LUXE Experiment
H. Abramowicz, M. Almanza Soto, M. Altarelli +131
This Technical Design Report presents a detailed description of all aspects of the LUXE (Laser Und XFEL Experiment), an experiment that will combine the high-quality and high-energ…
Antibubbles enable tunable payload release with low-intensity ultrasound
Nicolas Moreno-Gomez, Athanasios G. Athanassiadis, Albert T. Poortinga +1
The benefits of ultrasound are its ease-of-use and its ability to precisely deliver energy in opaque and complex media. However, most materials responsive to ultrasound show a weak…
Effects of multi-jet coupling on propulsive performance in underwater pulsed jets
Athanasios G. Athanassiadis, Douglas P. Hart
Despite the importance of pulsed jets for underwater propulsion, the effect of multiple-jet interactions remains poorly understood. We experimentally investigate how interactions b…
X-ray tomography system to investigate granular materials during mechanical loading
Athanasios G Athanassiadis, Patrick J. La Rivière, Emil Sidky +3
We integrate a small and portable medical x-ray device with mechanical testing equipment to enable in-situ, non-invasive measurements of a granular material's response to mechanica…
Particle Shape Effects on the Stress Response of Granular Packings
Athanasios G. Athanassiadis, Marc Z. Miskin, Paul Kaplan +7
We present measurements of the stress response of packings formed from a wide range of particle shapes. Besides spheres these include convex shapes such as the Platonic solids, tru…
Strain-stiffening in random packings of entangled granular chains
Eric Brown, Alice Nasto, Athanasios G. Athanassiadis +1
Random packings of granular chains are presented as a model polymer system to investigate the contribution of entanglements to strain-stiffening in the absence of Brownian motion.…
