Diversity of self-propulsion speeds reduces motility-induced clustering in confined active matter
(Royal Soc Chemistry, 2021)
Self-propelled swimmers such as bacteria agglomerate into clusters as a result of their persistent motion. In 1D, those clusters do not coalesce macroscopically and the stationary cluster size distribution (CSD) takes an ...
Effect of Added Mass Location on Manual Wheelchair Propulsion Forces
(2020-01-01)
This study investigated the influence of mass distribution on the handrim forces during manual propulsion in four different mobility tasks: Straightforward motion at self-selected speed; straightforward sprint; zero radius ...
Particles With Negative Mass: Production, Properties And Applications For Nuclear Fusion And Self-acceleration
(AMER SCIENTIFIC PUBLISHERSVALENCIA, 2015)
Influence of swimming strategy on microorganism separation by asymmetric obstacles
(Amer Physical Soc, 2013-05)
It has been shown that a nanoliter chamber separated by a wall of asymmetric obstacles can lead to an inhomogeneous distribution of self-propelled microorganisms. Although it is well established that this rectification ...
Swimming versus swinging effects in spacetime

Observed frequency-independent torque in flagellar bacterial motors optimizes space exploration
(American Physical Society, 2012-12-17)
A surprising feature of many bacterial motors is the apparently conserved form of their torque-frequency relation. Experiments indicate that the torque provided by the bacterial rotary motor is approximately constant over ...
Self-propulsion of N-hinged 'Animats' at low Reynolds number
(2003)
Optimal locomotion of micro-organisms (on a small Reynolds number flow) can be regarded as a sub-riemannian geometry on a principal bundle with a mechanical connection. Aiming at robotic applications, flagella are modeled ...
Effects of preparation on catalytic, magnetic and hybrid micromotors on their functional features and application in gastric cancer biomarker detection
(Elsevier, 2020)
Artificial micromotors evolve to improve multitasking performance in different research areas, and different power sources are combined to give rise to hybrid micromotors. Such combinations can alter physical features and ...
Could cell membranes produce acoustic streaming? Making the case for synechococcus self-propulsion
(Pergamon-Elsevier Science Ltd, 2011-04)
Sir James Lighthill proposed in 1992 that acoustic streaming (AS) within the mammalian cochlea could play a role in the transmission of acoustic signals to the auditory sensory cells. Microelectromechanical devices for ...
On the fluid dynamical effects of synchronization in side-by-side swimmers
(Multidisciplinary Digital Publishing Institute, 2019-12)
In-phase and anti-phase synchronization of neighboring swimmers is examined experimentally using two self-propelled independent flexible foils swimming side-by-side in a water tank. The foils are actuated by pitching ...
