Accelerating charging dynamics of electric double-layer capacitors
Megh Dutta, Ivan Palaia, Emmanuel Trizac +1
Electric double-layer capacitors (EDLCs), consisting of an ionic fluid between two metallic electrodes, are electrochemical energy storage devices complementary to batteries, allow…
Solvent-induced memory effects in a model electrolyte
Sleeba Varghese, Benjamin Rotenberg, Pierre Illien
The fluctuations of ions in polar solvents remain poorly understood theoretically due to the complex coupling between ionic motion and solvent polarization. Indeed, while all-atom…
The Angular Localization Function (ALF): a practical tool to measure solvent angular order with Molecular Density Functional Theory
Maïwenn Souetre, Benjamin Rotenberg, Guillaume Jeanmairet
Molecular density functional theory is a powerful technique for efficiently computing the spatially and orientationally dependent equilibrium density of a molecular solvent around…
Coupled concentration-charge dynamics in asymmetric 1:1 electrolytes, local transient response and fluctuations
Thê Hoang Ngoc Minh, Sleeba Varghese, Benjamin Rotenberg
We investigate the coupled dynamics of concentration and charge in asymmetric 1:1 electrolytes, focusing on the interplay between diffusion asymmetry and external electric fields.…
Tunable membrane-less dielectrophoretic microfiltration by crossing interdigitated electrodes
Nicolas Ruyssen, Bastien Oliva, Lylian Challier +2
Separation is a crucial step in the analysis of living microparticles. In particular, the selective microseparation of phytoplankton by size and shape remains an open problem, even…
Stochastic density functional theory for ions in a polar solvent
Pierre Illien, Antoine Carof, Benjamin Rotenberg
In recent years, the theoretical description of electrical noise and fluctuation-induced effects in electrolytes has gained a renewed interest, enabled by stochastic field theories…
