Universal behavior in diffuse charge dynamics with patterned electrodes
E. Krucker-Velasquez, E. Kirkinis, M. Olvera de la Cruz
Iontronic devices that replicate physiological processes will improve energy efficiency to support artificial-intelligence architectures. Energy storage and conversion devices, how…
Potential of mean force and underscreening of polarizable colloids in concentrated electrolytes
Emily Krucker-Velasquez, Martin Z. Bazant, Alfredo Alexander-Katz +1
This study uses advanced numerical methods to estimate the mean force potential (PMF) between charged, polarizable colloidal particles in dense electrolytes. We observe that when t…
Immersed boundary method for dynamic simulation of polarizable colloids of arbitrary shape in explicit ion electrolytes
Emily Krucker-Velasquez, James W. Swan, Zachary Sherman
We develop a computational method for modeling electrostatic interactions of arbitrarily-shaped, polarizable objects on colloidal length scales, including colloids/nanoparticles, p…
Underscreening and hidden ion structures in large scale simulations of concentrated electrolytes
Emily Krucker-Velasquez, James W. Swan
The electrostatic screening length predicted by Debye-Hückel theory decreases with increasing ionic strength, but recent experiments have found that the screening length can instea…
