Influence of Chloride and Electrolyte Stability on Passivation Layer Evolution at the Negative Electrode of Mg Batteries Revealed by operando EQCM-D. [PDF]
Angew Chem Int Ed EnglAbstractRechargeable magnesium batteries are promising for future energy storage. However, among other challenges, their practical application is hindered by low coulombic efficiencies of magnesium plating and stripping. Fundamental processes such as the formation, structure, and stability of passivation layers and the influence of different ...

A modulation QCM applied to copper electrodeposition and stripping [PDF]
, 2021 A fast electrochemical quartz crystal microbalance with dissipation monitoring (EQCM−D) was applied to copper electrodeposition and subsequent stripping. Accumulation brings the frequency noise down to the mHz range, corresponding to 0.1 % of a monolayer.

Quantification of the Mass and Viscoelasticity of Interfacial Films on Tin Anodes Using EQCM-D
ACS Applied Materials & Interfaces, 2015 Electrochemical quartz crystal microbalance coupled with dissipation (EQCM-D) is employed to investigate the solid electrolyte interphase (SEI) formation and Li insertion/deinsertion into thin film electrodes of tin. Based on the frequency change we find that the initial SEI formation process is rapid before Li insertion but varies significantly with ...

Controlling Competitive Radical Pathways: Insights From Aryl Diazonium Electrografting. [PDF]
ChemistryThis work shows that nitrobenzene diazonium electrografting results from competition between aryl and diazenyl radicals, which govern film composition. Using simulations and control strategies, grafting conditions are tuned to favor specific radicals. It enables selective formation of azo‐enriched films and paves the way toward the precise control of ...
