Validation of an innovative algorithm for detecting self-propulsion in manual wheelchair users [PDF]
Journal of Rehabilitation and Assistive Technologies EngineeringIntroduction Actimetry is increasingly used to measure physical activity (PA) for manual wheelchair (MWC) users. However, conversion of raw data into interpretable PA outcomes remains imprecise, and the differentiation between propulsion and non ...

Intrinsic enzymatic properties modulate the self-propulsion of micromotors [PDF]
Nature Communications, 2019 Self-propulsion of biocatalytic micro- and nanomotors is facilitated by enzymes converting substrates into products. Here, the authors show that intrinsic enzymatic properties such as conformational changes are crucial for the self-propulsion of silica ...

Hydrophobic Janus Foam Motors: Self-Propulsion and On-The-Fly Oil Absorption [PDF]
Micromachines, 2018 In this work, we for the first time have proposed and fabricated a self-propelled Janus foam motor for on-the-fly oil absorption on water by simply loading camphor/stearic acid (SA) mixture as fuels into one end of the SA-modified polyvinyl alcohol (PVA)

Clausius Relation for Active Particles: What Can We Learn from Fluctuations
Entropy, 2017 Many kinds of active particles, such as bacteria or active colloids, move in a thermostatted fluid by means of self-propulsion. Energy injected by such a non-equilibrium force is eventually dissipated as heat in the thermostat. Since thermal fluctuations

Numerical Self-Propulsion Assessment of a Generic Submarine Model at Various Forward Speeds
Journal of Eta Maritime Science, 2021 In this study, we use computational fluid dynamics (CFD) to investigate the self-propulsion characteristics of a submarine model. Predicting a marine vehicle’s self-propulsion features, and as a result, determining the thrust force required to drive the ...
