Abstract: A plurality of polymer slides, each having a polymer part with a first polymer surface portion uncoated and a second surface portion coated with a metal. The first and second surface portions each have different surface coating properties and have respective first and second specified degrees of hydrophobicity which are different from each other. A hydrophobic small molecule is located in the polymer part of each polymer slide, and the hydrophobic small molecule and the polymer are essentially inert to one another. Adjacent polymer slides are arranged in a manner that the first polymer surface of one slide faces a metal coated second surface portion of another slide. The hydrophobic small molecule evaporates from said first polymer surface portion of the polymer part of one polymer slide onto the adjacent metal coated second surface portion of another polymer slide.

Abstract: Nanostructured polyelectrolyte bilayers deposited by Layer-by-Layer deposition on nanoporous membranes can be selectively crosslinked to modify the polyelectrolyte charge density and control ionic selectivity independent of ionic conductivity. For example, the polyelectrolyte bilayer can comprise a cationic polymer layer, such as poly(ethyleneimine), and an anionic polymer layer, such as poly(acrylic acid). Increasing the number of bilayers increases the cation selectivity when the poly(ethyleneimine) layer is crosslinked with glutaraldehyde. Crosslinking the membranes also increases the chemical and mechanical strength of the polyelectrolyte films. This controllable and inexpensive method can be used to create ion-selective and mechanically robust membranes on porous supports for a wide range of applications.

Abstract: A system and method configured to restore ion exchange kinetic properties and purify resin is described. Degraded ion exchange kinetic properties of anion resin will eventually result in impurity slippage through resin charges. This system and method employs an acid catalyst in combination with sulfite cleaning solution to remove organic material and to protonate iron oxides for deconstruction and removal from anion resins. The cleaning solution, when applied via a cleaning vessel utilizing an eductor(s)/plenum and wedge-wire screen draw chamber, while controlling all phases of cleaning by electronic monitoring, yields complete restoration of ion exchange kinetics on usable resin. As such, the system and method provides a safe, effective, and vastly improved method for restoring anion resin kinetics and improving regeneration quality, for improved resin performance and minimizing resin replacement costs.
