New open-access publication in the exciting field of acoustofluidics! In a fruitful collaboration with Felix Brand and Klaus Stefan Drese from Coburg University of Applied Sciences and Arts, Sebastian Sachs, David Schreier, Christian Cierpka and Jörg König investigated the interplay of acoustophoretic and dielectrophoretic effects in a standing surface acoustic wave (sSAW) field. In the upper video, non-spherical particles not only align perpendicular to the pressure nodes of the sSAW, but are also decelerated when entering a region where a thin metal layer has been deposited on the substrate surface to screen the electric field. However, if the main flow direction is reversed in the video below, the particles tend to agglomerate at the edge of the metal layer. Explore the physics behind this and many more acoustofluidic phenomena by checking the experimental and numerical (3D) results in the freely accessible article:Interplay of acoustophoresis and dielectrophoresis in a standing surface acoustic wave field: from spherical to non-spherical particles | Microfluidics and Nanofluidics (springer.com)We would like to express our particular appreciation to Laura Weirauch from Universität Bremen, who helped providing the ellipsoidal particles, and to the team from ZMN, without whom this study would not have been possible. Furthermore, we thank the DFG for funding within the priority program PP2045 "MehrDimPart".
