When asymmetric Janus micromotors are immobilized on a surface, they act as chemically
powered micropumps, turning chemical energy from the fluid into a bulk flow. However, such …

The out of equilibrium nature of active systems can be exploited for the design of information-
based engines. We design two types of an active Szilard engine that use a Maxwell demon …

We show both numerically and analytically that a chemically patterned active pore can act
as a micro-or nanopump for fluids, even if it is fore-aft symmetric. This is possible due to a …

Lubrication theory is broadly applicable to the flow characterization of thin fluid films and the
motion of particles near surfaces. We offer an extension to lubrication theory by starting with …

Janus particles with the ability to move phoretically in self-generated chemical concentration
gradients are model systems for active matter. Their motion typically consists of straight …

Phoretic colloids self-propel thanks to surface flows generated in response to surface
gradients (thermal, electrical, or chemical), that are self-induced and/or generated by other …

An efficient, accurate, and flexible numerical method is proposed for the solution of the
swimming problem of one or more autophoretic particles in the purely diffusive limit. The …

Microchannels with asymmetrically ratcheted walls are here shown to behave as effective
and versatile microfluidic pumps if locally heated. When the boundary walls have different …

Autophoretic microswimmers self-propel via surface interactions with a surrounding solute
fuel. Chemically-active filaments are an exciting new microswimmer design that augments …

Artificial microswimmers are a new technology with promising microfluidics and biomedical
applications, such as directed cargo transport, microscale assembly, and targeted drug …
