Multiscale directed self-assembly of composite microgels in complex electric fields.
TL;DR: The thermosensitivity of the microgels was utilized to adjust the effective volume fraction and the dynamics of the system, which provided the possibility to dynamically "solidify" the assembly of the field-responsive particles by a temperature quench from their initial fluid state into an arrested crystalline state.

Ac electrokinetics: a review of forces in microelectrode structures
TL;DR: In this article, the frequency dependency and magnitude of electrothermally induced fluid flow are discussed for low frequencies (up to 500 kHz) and the effects of Brownian motion, diffusion and buoyancy force are discussed in the context of the controlled manipulation of sub-micrometre particles.
Journal ArticleDOI
The Motion and Precipitation of Suspensoids in Divergent Electric Fields
TL;DR: In this article, it was shown that the phenomena of dielectrophoresis and dielectro-precipitation can be observed under rather ideal conditions, though it is ordinarily often difficult to do so because of the presence of the more easily produced electrophoreis or ion-type migration of charged particles.
