Electrochemistry Study of Permselectivity and Interfacial Electron Transfers of a Branch-Tailed Fluorosurfactant Self-Assembled Monolayer on Gold

Molecules, 2018
We investigated the permselectivity and interfacial electron transfers of an amphiphilic branch-tailed fluorosurfactant self-assembled monolayer (FS-SAM) on a gold electrode by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The

Potentiometric Studies on Ion-Transport Selectivity in Charged Gold Nanotubes

Nanomaterials
Under ideal conditions, nanotubes with a fixed negative tube-wall charge will reject anions and transport-only cations. Because many proposed nanofluidic devices are optimized in this ideally cation-permselective state, it is important to know the ...

A Study on Tannic Acid-doped Polypyrrole Films on Gold Electrodes for Selective Electrochemical Detection of Dopamine

Sensors, 2005
Tannic acid-doped polypyrrole (PPY/TA) films have been grown on goldelectrodes for selective electrochemical detection of dopamine (DA). Electrochemicalquartz crystal microbalance (EQCM) studies revealed that, in vivid contrast toperchlorate-doped ...

Mussel-Inspired Surface Functionalization of AEM for Simultaneously Improved Monovalent Anion Selectivity and Antibacterial Property

Membranes, 2019
A facile membrane surface modification process for improving permselectivity and antimicrobial property was proposed. A polydopamine (PDA) coating was firstly fabricated on pristine anion exchange membrane (AEM), followed by in situ reduction of Ag ...

Oscillating the local milieu of polymersome interiors via single input-regulated bilayer crosslinking and permeability tuning

Nature Communications, 2022
Permselectivity of cellular membranes is crucial to normal cellular function but this has been hard to replicate in artificial cells. Here, the authors use pH-responsive polymersomes containing Schiff base moieties which can be used to control mesh size ...

Development of a New Hydrogel Anion Exchange Membrane for Swine Wastewater Treatment

Membranes, 2022
We developed a proprietary anion exchange membrane (AEM) for wastewater treatment as an alternative to commercial products. Following the successful development of a hydrogel cation exchange membrane on a porous ceramic support, we used the same approach

High Sensitivity of Electron Transfer Rates within Nafion Coatings Saturated with Os(bpy)^(2+)_3 to the Extent of Hydration of the Coating [PDF]

, 1995
The sensitivity of the electrochemical responses obtained from electroactive counterions incorporated in Nafion coatings to the extent of hydration of the coatings^(27-38) is shown to be enhanced significantly when the electroactive ion is the only ...
