Local Chemical Enhancement and Gating of Organic Coordinated Ionic-Electronic Transport
Record ion mobility and conductivities are revealed within a nanoscopic interfacial superhighway of an organic mixed ionic-electronic conductor. Fast ion transport can be controlled by hydrophobicity of molecules local to this channel, effectively gating ion access to the superhighway. This mechanism is used in a novel chemical sensing device which detects the dynamics of a local, buried chemical reaction. Read more »
