... cells are also active areas of research. Before multiphase flow in microchannels becomes a reality, however, several fundamental problems that arise from the small dimension of the channels must ... Most of these problems originate from the large curvature of the interface between two phases in these small channels. As a result, capillary effects and other related phenomena dominate in...

... volume, microelectromechanical systems (MEMS) are typically constructed on the micrometer scale, with some thin layers being perhaps in the nanometer range. As has already been demonstrated by microelectronic ... microelectronic circuits, the lateral dimensions of MEMS are being pushed into the nanometer range as well. This advance has been dubbed “nanoelectromechanical sys- tems,”...
