Abstract: A mixing apparatus is used to effect mixing between one or more fluid streams. The mixing apparatus generally functions by creating a transverse flow component in the fluid flowing within a channel without the use of moving mixing elements. The transverse or helical flow component of the flowing fluid or fluids can be created by weak modulations of the shape of the walls of the channel. Transverse or helical flow component can be created by grooves features defined on the channel wall. Specifically, the present invention can be used in laminarly flowing fluids. The mixing apparatus and methods thereof can effect mixing of a fluid or fluids flowing with a Reynolds number of less than about 100. Thus, the present invention can be used to mix a fluid flowing in the micro-regime. The mixing apparatus can be used to mix a fluid in a microfluidic system to significantly reduce the Taylor dispersion along the principal direction. The mixing apparatus can be used to increase the effective exposed area to promote diffusion of components between or within the fluid or fluids.

Abstract: A microtensiometer is provided that includes a substrate layer having an enclosed reservoir formed therein. A porous membrane is disposed on a surface of the substrate layer. The membrane includes a liquid side fluidly coupled to the reservoir and a vapor side fluidly coupled to a vapor interface. The porous membrane includes a plurality of through holes fluidly coupling the liquid reservoir to the vapor interface, and a nanoporous filler material disposed within the plurality of through holes. The filler material includes a plurality of open pores having a maximum diameter in the range of 0.2 to 200 nanometers. In one embodiment, the microtensiometer includes a molecular membrane disposed adjacent to the vapor side of the porous membrane. In one example, the molecular membrane is a highly crystalline polytetrafluoroethylene polymer having a microstructure characterized by nodes interconnected by fibrils. In one application, the microtensiometer may be used to measure the average water potential within a network of plant or tree xylem. In another application, the microtensiometer may be useful in real-time determination of the water potential in soil.
