Modified Kirchhoff's Laws for Electric-Double-Layer Charging in Arbitrary Porous Networks
Filipe Henrique, Pawel J. Zuk, Ankur Gupta
Understanding the dynamics of electric-double-layer (EDL) charging in porous media is essential for advancements in next-generation energy storage devices. Due to the high computat…
Asymmetric rectified electric and concentration fields in multicomponent electrolytes with surface reactions
Nathan Jarvey, Filipe Henrique, Ankur Gupta
Recent studies have utilized AC fields and electrochemical reactions in multicomponent electrolyte solutions to control colloidal assembly. However, theoretical investigations have…
Incorporating Ion-Specific van der Waals and Soft Repulsive Interactions in the Poisson-Boltzmann Theory of Electrical Double Layers
Aniruddha Seal, Utkarsh Tiwari, Ankur Gupta +1
Electrical double layers (EDLs) arise when an electrolyte is in contact with a charged surface, and are encountered in several application areas including batteries, supercapacitor…
Two-dimensional diffusiophoretic colloidal banding: Optimizing the spatial and temporal design of solute sinks and sources
Ritu R. Raj, C. Wyatt Shields, Ankur Gupta
In this work, we numerically investigate the impact of two-dimensional solute gradients on the distribution of colloidal particles, i.e., colloidal banding, induced via diffusiopho…
Ion Transport in an Electrochemical Cell: A Theoretical Framework to Couple Dynamics of Double Layers and Redox Reactions for Multicomponent Electrolyte Solutions
Nathan Jarvey, Filipe Henrique, Ankur Gupta
Electrochemical devices often consist of multicomponent electrolyte solutions. Two processes influence the overall dynamics of these devices: the formation of electrical double lay…
Charging Dynamics of Electrical Double Layers Inside a Cylindrical Pore: Predicting the Effects of Arbitrary Pore Size
Filipe Henrique, Pawel J. Zuk, Ankur Gupta
Porous electrodes are found in energy storage devices such as supercapacitors and pseudocapacitors. However, the effect of electrode-pore-size distribution over their energy storag…
