Curved channels are one of the most fundamental units natural or artificial channels, in which there different kinds obstacles; these include vegetation patches, bridge piles, electrical tower foundations, etc., all present over a channel bend, and can significantly alter hydrodynamic characteristics when compared to bare bed. In this study, laboratory experiments numerical simulations were com...

Capture and, subsequently, in situ characterization of microparticles generally require complex fabrication processes and sophisticated techniques microfluidic devices. In this paper, we present a simple inexpensive technique for capturing applying chemical agents to individual charged with the same glass microelectrode circular channel. The device features thin poly-dimethyl-siloxane (PDMS) la...
