Switching ionic diode states with proton binding into intrinsically microporous polyamine films (PIM-EA-TB) immersed in ethanol

چکیده
Intrinsically microporous polyamines (PIM-EA-TB) provide tertiary amine binding sites for protons and in this way allow switching/gating from a low ionic conductivity state to semipermeable anion through micropores. In ethanolic NaClO4 media PIM-EA-TB films (approx. 10 μm thick; deposited asymmetrically onto diameter microhole 5 thick Teflon) is lowered by ion exclusion compared observed aqueous environments. However, the presence of ethanol are shown switch essentially insulating anionic diode behaviour. Similar observations reported Cu2+ but not other types cations such as Na+, K+, Mg2+ (all perchlorate salts). Binding constants evaluated, protonation identified cause gating both H+ Cu2+. Both chemical electrochemical gating/switching demonstrated placing platinum electrode close film applying positive or negative bias locally generate acid/base.

Investigation of resistive switching in anodized titanium dioxide thin films
In this work, TiO2 nanostructures were grown on titanium thin films by electrochemical anodizing method. The bipolar resistive switching effect has been observed in Pt/TiO2/Ti device. Resistive switching characteristics indicated the TiO2 nanotubes are one of the potential materials for nonvolatile memory applications. Increasing anodizing duration will increase nanotube lengths which itself c...
متن کاملSelf-assembled oxide films with tailored nanoscale ionic and electronic channels for controlled resistive switching
Resistive switches are non-volatile memory cells based on nano-ionic redox processes that offer energy efficient device architectures and open pathways to neuromorphics and cognitive computing. However, channel formation typically requires an irreversible, not well controlled electroforming process, giving difficulty to independently control ionic and electronic properties. The device performan...
متن کاملProton source size measurements in the eA-->e'ppX reaction.
Two-proton correlations at small relative momentum q were studied in the eA(3He,4He,C,Fe)-->e(')ppX reaction at E(0)=4.46 GeV using the CLAS detector at Jefferson Lab. The enhancement of the correlation function at small q was found to be in accordance with theoretical expectations. Sizes of the emission region were extracted, and proved to be dependent on A and on the proton momentum. The size...
متن کاملElectrotunable Lubricity with Ionic Liquid Nanoscale Films
One of the main challenges in tribology is finding the way for an in situ control of friction without changing the lubricant. One of the ways for such control is via the application of electric fields. In this respect a promising new class of lubricants is ionic liquids, which are solvent-free electrolytes, and their properties should be most strongly affected by applied voltage. Based on a min...
