Multiresolution Wavelet Method for Trend Removal in Electrochemical Noise Data From LiFePO₄ Batteries

IEEE Access
Electrochemical potential noise signals from LiFePO4 batteries often contain a slowly varying trend component that overlaps with and distorts the intrinsic low-frequency electrochemical noise.

Moving Beyond Oligoethers: Polar Side‐Chain Engineering for Aqueous Mixed Ionic–Electronic Conductors

Advanced Functional Materials, EarlyView.
We investigate how side‐chain chemistry and hydrogen bonding affect electrochemical doping in poly(propylenedioxythiophene) polymers. Replacing oligoether side chains with hydroxyl or carboxylic acid groups nearly triples electrochemical conductivity.

Study of the Corrosion Behaviour of the Steel Q315NS Heat-affected Zone in H2SO4 Solution by Electrochemical Noise

International Journal of Electrochemical Science, 2018
To provide insight into the influence of the welding thermal cycle on the corrosion behaviour of Q315NS steel, the corrosion behaviours of the base metal (BM) and heat-affected zone (HAZ) in 50 wt.% H2SO4 solution at 25 °C were investigated with surface ...

Dual‐Inductive and Programmable Switching: A New Paradigm in Ionic Interface‐Controlled Perovskite Memory

Advanced Functional Materials, EarlyView.
A fully programmable, dual‐inductive switchable halide perovskite memristor is demonstrated through precise BDAI2‐mediated interface engineering. This ion‐modulating layer suppresses stochastic filamentary growth, enabling stable, non‐filamentary switching via dynamic barrier modulation.

Near‐Infrared Light‐Driven Zn/Au Janus Micromotors for Multiplex SERS Detection of Anticancer Drugs

Advanced Functional Materials, EarlyView.
Zn/Au Janus micromotors, propelled by thermophoretic effects under NIR light, function as active SERS platforms for single and multiplex detection of anticancer drugs. Their dynamic motion enhances analyte exchange at the Au interface, reducing saturation and competitive adsorption, thereby improving sensitivity and extending the linear detection range.
