Confinement‐Induced Donnan Potential Enables Sealed Hydrovoltaic Power From Microliter Water
Advanced Materials, EarlyView.An ultrathin MXene/cellulose nanofiber (CNF) nanochannel‐based hydrovoltaic generator produces sustained direct current (DC) from a single microliter droplet under sealed operation. Asymmetric nanochannel confinement establishes a persistent ion gradient and a confinement‐induced Donnan potential, harvesting the interfacial free energy released upon ...
