Hybrid Amperometric and Potentiometric Sensing Based on a CMOS ISFET Array [PDF]

, 2017
Potentiometry and amperometry are some of the most important techniques for electroanalytical applications. Integrating these two techniques on a single chip using CMOS technology paves the way for more analysis and measurement of chemical solutions.

Dissolution périodique du nickel dans l'acide nitrique en présence de chlorures

CHIMIA, 1975
In the presence of Cl-, nickel dissolves periodically in HNO3 for normalities between 9 < N < 17. This phenomenon is investigated by potentiometry and thermometry.
