Abstract

loops, demonstrating that extreme confinement alone is insufficient to induce ionic memory. Introducing a molecular solvent (such as acetonitrile) or applying compositional asymmetry (salt-concentration gradients) restores pinched hysteresis. These results identify solvent dielectric properties, miscibility, and ion-correlation strength as key control parameters for enabling or suppressing ionic memory in nanochannels, even under strong confinement. Our findings provide both mechanistic insight into ionic memristor behavior and practical methods for controlling hysteresis in nanofluidic devices.
