Electrochemical sensors

, 2023
This thesis focuses on the development of electrochemical sensors, in which three main perspectives are explored. First, bespoke pH sensors for near-neutral conditions are developed for both freshwater and seawater. Inspired by the importance and challenge of detection in seawater, bromide and chloride quantifications are subsequently studied.

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
