Combined amperometric-potentiometric oxygen sensor
(2020)The present investigation describes the results of the performance and the assessment of a combined electrochemical oxygen sensor, equipped with a diffusion barrier and consisted of an electrochemical cell-pump and a ... -
Determination of nitrous oxide concentration using a solid-electrolyte amperometric sensor
(2019)Herein, are presented the results of the investigation of an electrochemical sensor, based on oxygen-conducting yttria stabilized zirconia (YSZ) solid-state electrolyte, used for the determination of nitrous oxide in gas ... -
An electrochemical method for the determination of concentration and diffusion coefficient of ammonia‑nitrogen gas mixtures
(2018)In the present investigation an electrochemical method for the determination of concentration and diffusion coefficient of ammonia in nitrogen (NH3/N2) is proposed by the means of a solid-state amperometric sensor based ... -
Ion incorporation on the Zr2CS2 MXene monolayer towards better-performing rechargeable ion batteries
(2022)We study Li and, for the first time, K, Mg and Zn ion intercalation on the surface of the Zr2CS2 MXene monolayer, taking advantage of the fact that the S terminations lower the diffusion barrier of the ions. We find that ... -
Mg-ion diffusion on the surface of Ti3C2S2 MXene
(2022)Obtaining the structure of the Ti3C2S2 MXene using Density Functional Theory, we study here for the first time the adsorption and diffusion of an Mg ion on the surface of the MXene. We find a very strong adsorption and the ... -
Orientational randomness and its influence on the barrier properties of flake-filled composite films
(2017)This direct numerical study investigated the effect of orientational randomness on the barrier properties of flake-filled composites. Over 2500 simulations have been conducted in two-dimensional, doubly periodic unit cells, ... -
