ABSTRACT:  Complexes formed in systems containing both positive and negative charges are of fundamental importance in a variety of materials applications.  A common method for producing polyelectrolyte complex films is to sequentially deposit oppositely charged polymers, an effective but tedious process that is not readily scalable.  A focus on this talk is on the deposition of relatively thick films directly onto conducting surfaces, using electrochemical processes to modulate the local pH.  The process is carried out on a quartz crystal microbalance, which in addition to

ABSTRACT:  Carbon nanotube (CNT)/polymer nanocomposites (CPNs) have recently drawn great interest for use in electronics, due to their superior properties such as tunable electrical conductivity, light weight, low cost, corrosion resistance, processability, etc. (compare with properties of currently used metals). In fact, the polymer matrix is insulative; however, incorporating a low content of conductive filler transforms it into conductive via forming a conductive network.

ABSTRACT: In this work, the issue of stability for two-phase incompressible flow in homogeneous porous media out of the Darcy regime (i.e. when inertia must be taken into account) is considered. The development is based on a macroscopic model derived by upscaling the pore-scale Navier-Stokes equations, assuming that the inertial correction is quadratic in the filtration velocity, as widely admitted with the classical Darcy-Forchheimer model.
