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…
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…
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.…
