Universal motion of mirror-symmetric microparticles in confined Stokes flow
Rumen N. Georgiev, Sara O. Toscano, William E. Uspal +4
Comprehensive understanding of particle motion in microfluidic devices is essential to unlock novel technologies for shape-based separation and sorting of microparticles like micro…
Self-Thermoelectrophoresis at Low Salinity
Joost de Graaf, Sela Samin
A locally heated Janus colloid can achieve motion in a fluid through the coupling of dissolved ions and the medium's polarizibility to an imposed temperature gradient, an effect kn…
Dynamic Stern layers in charge-regulating electrokinetic systems: three regimes from an analytical approach
B. L. Werkhoven, S. Samin, René van Roij
We present analytical solutions for the electrokinetics at a charged surface with both non-zero Stern-layer conductance and finite chemical reaction rates. We have recently studied…
Flow-induced surface charge heterogeneity in electrokinetics due to Stern-layer conductance coupled to reaction kinetics
B. L. Werkhoven, J. C. Everts, S. Samin +1
We theoretically study the electrokinetic problem of a pressure-induced liquid flow through a narrow long channel with charged walls, going beyond the classical Helmholtz-Schmoluko…
Calculating the motion of highly confined, arbitrary-shaped particles in Hele-Shaw channels
Bram Bet, Rumen Georgiev, William Uspal +3
We combine theory, numerical calculations, and experiments to accurately predict the motion of anisotropic particles in shallow microfluidic channels, in which the particles are st…
Tuning the motility and directionality of self-propelled colloids
Juan Ruben Gomez-Solano, Sela Samin, Celia Lozano +3
Microorganisms are able to overcome the thermal randomness of their surroundings by harvesting energy to navigate in viscous fluid environments. In a similar manner, synthetic coll…
