Identification of unknown diffusion coefficient in pure diffusive linear model of chronoamperometry. I. The theory

, 2010
Coefficient identification problem for diffusion equation u (t) (x, t) = (D(x)u (x) (x, t)) (x) arising in chronoamperometry is studied. The adjoint problem approach is developed for the case when the output measured data is given in the form of left ...

Chronoamperometry as effective alternative technique for electro-synthesis of ortho-phenylendiamine permselective films for biosensor applications

, 2020
Analyte quantification in first generation electrochemical biosensors is threatened by electro-active molecules, such as ascorbic acid (AA). Electrochemical deposition of ortho-phenylendiamine (oPD) on transducer considerably reduces AA interfering ...

Gate Metal‐Driven Sensing and Memory Bifunctionality in Intrinsically Stretchable Organic Electrochemical Transistors for Soft Neuromorphic Systems

Advanced Science, EarlyView.
Intrinsically stretchable OECTs enable bifunctional operations via gate engineering. Polarizable Ag/AgCl gates provide volatile sensing, while Au gates enable non‐volatile memory. The SEBS‐blended channel maintains performance under strain, supporting reliable signal transduction.

Chelation‐Driven Dual‐Interface Regulation for Long‐Life Aqueous Zn–I2 Batteries

Advanced Science, EarlyView.
Zn2+–TPEN coordination generates TPEN‐derived coordination species (TCC) that contribute to the regulation of both electrode interfaces. At the Zn anode, it creates an interfacial environment with reduced water accessibility that suppresses HER and corrosion while promoting uniform deposition; at the I2 cathode, it captures polyiodide to inhibit ...

Simulation and Performance Optimization of an Amperometric Histamine Detection System

Proceedings, 2018
One of the most widely known biogenic amines is histamine, which plays an important role in the human immune system. Some people suffer from allergic reactions after a histamine-rich diet; this is called histamine intolerance.

Weakly Coordinated Solvent Network‐Induced Ternary Water‐Deficient Eutectic Electrolytes for Low‐Polarization Zn Anodes

Advanced Science, EarlyView.
A water‐deficient ternary eutectic electrolyte employs weakly coordinating solvents to decouple strong solvation interactions, constructing a loose and dynamic solvation network. This optimized solvation structure accelerates Zn2+ transport and interfacial kinetics, promotes robust SEI formation, and ultimately enables highly stable and reversible Zn ...
