UC Irvine, Tel Aviv Team Build Ion Pump With No Moving Parts

New ion pump technology promises more efficient water desalination

Researchers from the University of California, Irvine, and Tel Aviv University have unveiled a first-of-its-kind ratchet-based ion pump.

First-of-its-kind ion pump developed for seawater desalination, energy and biomedical applications

Researchers at the University of California, Irvine, Israel's Tel Aviv University and other institutions have developed a first-of-its-kind membrane through which charged molecules pass using nothing more than a rapidly switching low-voltage signal. This "ratchet-based ion pump" has no moving parts and requires no chemical reactions.

Ratchet-Based Ion Pumps for Selective Ion Separations

The development of a highly selective, membrane-based ion separation technology could significantly improve the sustainability and energy efficiency of water treatment technologies and emerging applications, such as electrochemical CO2 reduction, extraction of valuable metals from seawater, and battery recycling. In this work, we show through computational modeling that an electronic flashing ratchet mechanism can be used for high-precision ion s

Scientists create an ion pump with no moving parts that removes up to 50% of the salt from water using low voltage, potentially revolutionizing desalination, energy, and metal extraction with clean and efficient technology.

Desalination could enter a new phase with the creation of an ion pump without moving parts, developed by researchers at the University of California, Irvine, and Tel Aviv University. The device managed to remove up to 50% of the salt from water in proof-of-concept tests, using only a low-voltage electrical signal and rapid switching.
