摘要： Porous filters having uniform pore size and close packing density are described, along with methods and apparatus for making the porous filters based on nanopatterning. One method includes applying a polymeric liquid to a mold consisting of an array of posts having a desired pore size and distribution. Solidification of polymeric membrane followed by separation from the mold produces a polymer membrane with a predetermined spaced array of pores. A pre-filter film can also be bonded with the membrane during formation to provide increased mechanical support and filtration of larger particles on the input side of the filter. Other process variants are described, including methods for incorporating additional functionalities to the filter.

摘要： The invention relates to a device, a method, and a kit for separating particles of different sizes in a liquid. The invention additionally relates to applications of the device. The device and the method involve the capability of binding particles to solid phase particles with different diameters in a liquid, whereby the hydrodynamic diameter of the solid-phase particles determines whether the particles can pass through pores of a filter element, the diameter of said pores being modifiable in a controlled manner (e.g., the diameter can be increased or decreased). Thus, particles of equal size (e.g., B-cells and T-cells) of a liquid can be separated from one another with a high degree of separation efficiency, wherein the particles can be separated simply, quickly, and inexpensively. High yields can be produced, and the particles can be provided in a therapeutically applicable liquid.

摘要： A hydrophobic biofilm membrane modified with a spiropolyurethane may be used for desalination of salt water to fresh water. The spiropolyurethane component of the membrane can produce a hydrophobic spin membrane boundary which attracts saline water, and where the hydrophobic spin membrane boundary can comprise a hinge-like motion for capture of salt molecules via a loose pore-gate spongy membrane surface texture while allowing desalinated water to flow through the porous membrane. The membrane is useful in both reverse osmosis (RO) and membrane distillation (MD) separations, including the desalination.

摘要： A photodialysis device that can desalinate saline streams is described herein. The device can have a desalination rate that is significantly faster than current solar thermal desalination technology. Salt is removed from water by passing ionic current derived from sunlight through this water using dye-sensitized membranes. The device can serve as a distributed, low-cost technology that can efficiently and effectively desalinate low salinity sources of water, which is particularly useful for agriculture and drinking water applications.
