Molecular interpretability of the bulk electrochemical impedance of concentrated electrolytes

Connie J Fairchild, Stephen J Cox, Benjamin Rotenberg, Thomas Sayer

Electrochemical impedance spectroscopy (EIS) is a widely used technique to understand time-dependent response and relaxation under applied voltage. While these spectra contain a wealth of information, major gaps in our understanding can hinder our ability to interpret EIS spectra in terms of…

Probing the Enhancement of 1H NMR Relaxation Rate in Hydrated Boehmite Systems

Alice Ducroix, Zlanseu Ruth Tan, Thierry Allard, Thibaud Chevalier, Guillaume Mériguet, Sandrine Leclerc, Serge Durand-Vidal, Flavien Guenneau, Natalie Malikova, Vincent Sarou-Kanian, Anne‐laure Rollet, Pierre Levitz

The 1H NMR relaxation dispersion (NMRD) profile of water in boehmite systems has been studied in detail. The NMRD profiles, recorded for weakly hydrated particles up to diluted suspensions, exhibit the very same shape, and a mastercurve can be obtained. 1H NMR relaxation rate R1 strongly varies…

Dynamics of charge fluctuations in nanocapacitors: Effects of salt concentration and electrode metallicity from Brownian dynamics

Paul Desmarchelier, Benjamin Rotenberg

Electric double-layer capacitors (EDLCs) rely on the dynamical response of confined electrolytes to store and release charge, yet the interplay between ion transport, electrostatic interactions, and electrode metallicity remains poorly understood at the nanoscale. In this work, we develop a…

Quantifying the Features of an Amorphous Solid's Local Yield Surface

Spencer Fajardo, Paul Desmarchelier, Sylvain Patinet, Michael L Falk

In continuum mechanics, a yield surface defines the boundary in stress space between elastic response and the onset of plastic flow. In two-dimensional Lennard-Jones model glasses, we construct local analogues of this surface and show that their angular dependence is dominated by regions with a…
