recommendations! Published in 2017 at "Environmental Science and Technology Letters"

DOI: 10.1021/acs.estlett.7b00130

Abstract: Biogeochemical processes are often confined to very narrow zones in aquatic systems. Therefore, highly resolved in situ measurements are required to study these processes. Potentiometric solid-contact ion selective electrodes (SC-ISEs) are promising tools for such… read more here.

DOI: 10.1039/d5cc05087a

Abstract: A novel solid contact is developed through electrodeposition, co-anchoring ethyl viologen and ferrocene on porous graphene. The proposed solid-contact ion-selective electrode using this material shows large capacitance, low drift, high reproducibility, no aqueous layer, and… read more here.
