Bubble dynamics near the onset of single-bubble sonoluminescence [PDF]

Physical Review E, 2004
A number of groups have reported measurements of the location in the parameter space of bubble size versus acoustic pressure amplitude of shape- and size-stable bubbles. For air/water systems, a general trend emerges: stable bubbles are found on one of two line paths in this space defined by their range of acoustic pressure.

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Grouping method for acoustic wave propagation in bubbly liquids

Engineering Applications of Computational Fluid Mechanics
The bubble radii within a bubble cluster typically distribute over a wide range, and bubble dynamics under acoustic excitation are strongly dependent on the radius. To accurately predict the oscillation behaviour of the bubble cluster and the propagation

2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots

Advanced Functional Materials, EarlyView.
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

ATP‐Mediated Bidirectional Communication Between Natural and Artificial Cells for Controlled Bioreactions

Advanced Functional Materials, EarlyView.
Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...

Bubble Dynamics in a Two-Phase Bubbly Mixture [PDF]

Volume 7: Fluid Flow, Heat Transfer and Thermal Systems, Parts A and B, 2010
The dynamics of a primary relatively large bubble in a water mixture including very fine bubbles is investigated experimentally and the results are provided to several parallel on-going analytical and numerical approaches. The main/primary bubble is produced by an underwater spark discharge from two concentric electrodes placed in the bubbly medium ...

Effects of Polydispersity in Bubbly Flows [PDF]

, 2010
This thesis concerns the dynamics of bubbly flows with a distribution of equilibrium bubble sizes. The main goal is to formulate the physical and numerical models of continuum bubbly flows that enable us to efficiently compute the average mixture ...
