Separation: Acoustic Separation of Nanoparticles in Continuous Flow (Adv. Funct. Mater. 14/2017)

Heuristic Continuous Base Flow Separation

A digital filtering algorithm for continuous base flow separation is compared to physically based simulations of base flow. It is shown that the digital filter gives comparable results to model simulations in terms of the multiyear base flow index when a filter coefficient is used that replicates the watershed-specific time delay of model simulations. This way, the application of the heuristic ...

Numerical Simulation of Particle Separation in the Fluid Flow in a Microchannel Including Spiral and Acoustic Regions

Particulate separation has many applications in medicine, biology and industry. In this research, the separation of polystyrene particles with a diameter of 10, 20 and 30 μm in the fluid flow of a microchannel is investigated. The microchannel consists of a spiral region and a straight region under the influence of acoustic waves. In the spiral region, the particles under hydrodynamic effects u...

Combined microfluidic-micromagnetic separation of living cells in continuous flow.

This paper describes a miniaturized, integrated, microfluidic device that can pull molecules and living cells bound to magnetic particles from one laminar flow path to another by applying a local magnetic field gradient, and thus selectively remove them from flowing biological fluids without any wash steps. To accomplish this, a microfabricated high-gradient magnetic field concentrator (HGMC) w...

Blood cell separation in the dog by continuous flow centrifugation.

T HERE IS EVIDENCE that homologous granulocytes are beneficial in the treatment of bacterial infection when supplied to a granulocytopenic recipient. Control studies have not been done but Freireich et al.’ and Schwarzenberg et al.2 have demonstrated lysis of fever, and clinical improvement in granulocytopenic patients given granulocytes from donors with chronic myelocytic leukemia (CML ) . Cro...
