, 2023 Electrohydrodynamic atomization (EHDA) provides unparalleled control over the size and production rate of particles from solution. However, conventional methods produce highly charged particles that are not appropriate for inhalation drug delivery.

Swimming and Swarming of Self-Propelled Particles [PDF]
, 2009 A number of micro-organisms and cells, such as sperm and some spieces of roundworms (nematodes), employ a sinusoidal beating motion of their rod-like body to swim though a fluid medium. For the motion of these microscopic swimmers, the viscosity is dominating and the inertia is negligible.

Circular Motion of Asymmetric Self-Propelling Particles [PDF]
Physical Review Letters, 2013 Micron-sized self-propelled (active) particles can be considered as model systems for characterizing more complex biological organisms like swimming bacteria or motile cells. We produce asymmetric microswimmers by soft lithography and study their circular motion on a substrate and near channel boundaries.

Role of particle conservation in self-propelled particle systems [PDF]
, 2013 Actively propelled particles undergoing dissipative collisions are known to develop a state of spatially distributed coherently moving clusters. For densities larger than a characteristic value, clusters grow in time and form a stationary well-ordered

Non-Gaussian statistics for the motion of self-propelled Janus particles: Experiment versus theory [PDF]
, 2013 Spherical Janus particles are one of the most prominent examples for active Brownian objects. Here, we study the diffusiophoretic motion of such microswimmers in experiment and in theory.

Forces that control self-organization of chemically-propelled Janus tori
Communications Physics, 2022 The presence of a constraining environment exerts an influence on the behavior of self-propelled synthetic microswimmers, challenging the prediction and control of their individual and collective behaviour in realistic situations.

Cavitation Inception on Microparticles: A Self-Propelled Particle Accelerator [PDF]
Physical Review Letters, 2004 Corrugated, hydrophilic particles with diameters between 30 and 150 microm are found to cause cavitation inception at their surfaces when they are exposed to a short, intensive tensile stress wave. The growing cavity accelerates the particle into translatory motion until the tensile stress decreases, and subsequently the particle separates from the ...

Self-organization in systems of self-propelled particles [PDF]
Physical Review E, 2000 We investigate a discrete model consisting of self-propelled particles that obey simple interaction rules. We show that this model can self-organize and exhibit coherent localized solutions in one- and in two-dimensions.In one-dimension, the self-organized solution is a localized flock of finite extent in which the density abruptly drops to zero at the
