Frequency-Dependent Conductivity of Concentrated Electrolytes: A Stochastic Density Functional Theory
Haggai Bonneau, Yael Avni, David Andelman +1
The response of ionic solutions to time-varying electric fields, quantified by a frequency-dependent conductivity, is essential in many electrochemical applications. Yet, it consti…
Sociohydrodynamics: data-driven modelling of social behavior
Daniel S. Seara, Jonathan Colen, Michel Fruchart +3
Living systems display complex behaviors driven by physical forces as well as decision-making. Hydrodynamic theories hold promise for simplified universal descriptions of socially-…
Charge Regulation of Polyelectrolyte Gels: Swelling Transition
Bin Zheng, Yael Avni, David Andelman +1
We study the effects of charge-regulated acid/base equilibrium on the swelling of polyelectrolyte gels, by considering a combination of the Poisson-Boltzmann theory and a two-site…
Conductance of concentrated electrolytes: multivalency and the Wien effect
Yael Avni, David Andelman, Henri Orland
The electric conductivity of ionic solutions is well understood at low ionic concentrations of up to a few millimolar but becomes difficult to unravel at higher concentrations that…
Conductivity of Concentrated Electrolytes
Yael Avni, Ram M. Adar, David Andelman +1
The conductivity of ionic solutions is arguably their most important trait, being widely used in electrochemical, biochemical, and environmental applications. The Debye-Hückel-Onsa…
Phase Separation of Polyelectrolytes: The Effect of Charge Regulation
Bin Zheng, Yael Avni, David Andelman +1
Complex coacervation, known as the liquid-liquid phase separation of solutions with oppositely charged polyelectrolytes, has attracted substantial interest in recent years. We stud…
Brownian motion of a charged colloid in restricted confinement
Y. Avni, S. Komura, D. Andelman
We study the Brownian motion of a charged colloid, confined between two charged walls, for small separation between the colloid and the walls. The system is embedded in an ionic so…
Critical behavior of charge-regulated macro-ions
Yael Avni, Rudolf Podgornik, David Andelman
Based on a collective description of electrolytes composed of charge-regulated macro-ions and simple salt ions, we analyze their equilibrium charge state in the bulk and their beha…
Charge Oscillations in Ionic Liquids: A Microscopic Cluster Model
Yael Avni, Ram M. Adar, David Andelman
In spite of their enormous applications as alternative energy storage devices and lubricants, room temperature ionic liquids (ILs) still pose many challenges from a pure scientific…
Charge Regulation with Fixed and Mobile Charges
Yael Avni, David Andelman, Rudolf Podgornik
Uncompensated charges do not occur in Nature and any local charge should be a result of charge separation. Dissociable chemical groups at interfaces in contact with ions in solutio…
Charge Regulating Macro-ions in Salt Solutions: Screening Properties and Electrostatic Interactions
Yael Avni, David Andelman, Tomer Markovich +1
We revisit the charge-regulation mechanism of macro-ions and apply it to mobile macro-ions in a bathing salt solution. In particular, we examine the effects of correlation between…
