Nonlocal dielectric properties of water: the role of electronic delocalisation
Darka LabaviÄ, Florian N. Brünig, Roland R. Netz +2
The nonlocal dielectric properties of liquid water are studied in the context of {\it ab initio} molecular dynamics simulations based on density functional theory. We calculate the…

pH gradient-driven deformation of a crista-like vesicle
Yorgos Chatziantoniou, Hélène Berthoumieux
The inner membrane of mitochondria presents folds, the cristae, which are the production place of ATP. This synthesis is driven by a flow of protons confined to the surface of the…

Nonlinear conductivity of aqueous electrolytes: beyond the first Wien effect
Hélène Berthoumieux, Vincent Démery, A. C. Maggs
The conductivity of strong electrolytes increases under high electric fields, a nonlinear response known as the first Wien effect. Here, using molecular dynamics simulations we sho…
