Latest Patents

One of Larson's latest patents is the "Ratchet-based ion pumping membrane systems." This invention describes an ion pump system that utilizes an electronic ratchet mechanism. By modulating a spatially varying electric potential distribution, the system can generate a net ionic current and voltage. The ion pumping membrane system integrates an ion-permeable layer with ion-selective membranes. The electric potential distribution within the ion-permeable layer is modulated through external stimuli. When immersed in a solution, ions within the ion-permeable layer experience a time-varying, spatially asymmetric electric field distribution, resulting in ratchet-driven direction pumping. This technology has potential applications in desalination.

Another notable patent is the "Vapor phase photo-electrochemical cell." This disclosure provides systems, methods, and apparatus related to a vapor phase photo-electrochemical cell. The device includes a photovoltaic cell, a cathode disposed on the photovoltaic cell, an ionomer membrane on the cathode, and an anode on the ionomer membrane. The cathode features a cathode catalyst, while the anode includes an anode catalyst. Both the anode and cathode are designed to be transmissive to the solar radiation spectrum, enhancing the efficiency of the system.
