Electrochemical Noise Analysis of the Corrosion of Titanium Alloys in NaCl and H₂SO₄ Solutions

Metals, 2021
Titanium alloys have been used in aerospace, aeronautic, automotive, biomedical, structural, and other applications because titanium alloys have less density than materials like steel and support higher stress than Al-alloys.

Noise as Data: Nucleation of Electrochemically Generated Nanobubbles [PDF]

ACS Nano, 2019
Single-entity electrochemistry aims to expand the toolkit for probing matter at the nanometer scale. Originally focused largely on electrochemically active systems, these methods are increasingly turning into versatile probes complementary to optical, electrical, or mechanical methods.

Empirical study of noise dependence in electrochemical sensors

5th IEEE International Workshop on Advances in Sensors and Interfaces IWASI, 2013
We report the experimental study of noise in electrochemical biosensors as related to voltage and concentration. A comparison with experiments is performed for H2O2 and Ferrocyanide with bare sensors, and with sensors functionalized with Multi-Walled Carbon Nanotubes (MWCNT) modified electrodes. Chronoamperometry measurements at different voltages were
