Efficient & Selective Ion Pumps based on Ratchet Mechanisms

I propose a novel membrane-like device that utilizes a ratchet mechanism to drive ions selectively up a concentration gradient. This device can serve as a building block for an efficient, ion selective separations technology. Ion selective separation with membrane-based processes may advance dramatically technologies for water treatment, resource extraction from sea water, ion specific sensors and many other applications. Moreover, since about 10-15% of the global energy consumption is used for chemical separations, a high efficiency, membrane-based ion separation processes can reduce greenhouse gas emissions significantly. However, membrane-based ion selective separation is a longstanding…
