Unraveling Modular Microswimmers: From Self-Assembly to Ion-Exchange Driven Motors
Benno Liebchen, Ran Niu, Thomas Palberg +1
Active systems contain self-propelled particles and can spontaneously self-organize into patterns making them attractive candidates for the self-assembly of smart soft materials. O…
Modular approach to microswimming
Ran Niu, Thomas Palberg
The field of active matter in general and microswimming in particular has experienced a rapid and ongoing expansion over the last decade. A particular interesting aspect is provide…
Colloidal electro-phoresis in the presence of symmetric and asymmetric electro-osmotic flow
Denis Botin, Jennifer Wenzl, Ran Niu +1
We characterize the electro-phoretic motion of charged sphere suspensions in the presence of substantial electro-osmotic flow using a recently introduced small angle super-heterody…
Seedless assembly of colloidal crystals by inverted micro-fluidic pumping
Ran Niu, Thomas Palberg
We propose a simple seedless approach to assemble millimeter sized monolayer single colloidal crystals with desired orientations at predetermined locations on an unstructured charg…
Large scale Micro-Photometry for high resolution pH-characterization during electro-osmotic pumping and modular micro-swimming
Ran Niu, Stanislav Khodorov, Julian Weber +2
Micro-fluidic pumps as well as artificial micro-swimmers are conveniently realized exploiting phoretic solvent flows based on local gradients of temperature, electrolyte concentrat…
Formation of a transient amorphous solid in low density aqueous charged sphere suspensions
Ran Niu, Sabrina Heidt, Ramsia Sreij +3
Colloidal glasses form from hard spheres, nearly hard spheres, ellipsoids and platelets or their attractive variants have been studied in detail. Complementing and checking theoret…
