Interfacial Layering in the Electric Double Layer of Ionic Liquids [PDF]

open access: yesPhysical Review Letters, 2020
Ions in ionic liquids and concentrated electrolytes reside in a crowded, strongly-interacting environment, leading to the formation of discrete layers of charges at interfaces. Here, we propose a continuum theory that captures the transition from overscreening-- alternating layers of excess charge at low surface potential, to overcrowding-- the ...

Simulation of the Impedance of the Electrical Double Layer and Evaluation of the Surface Excess Concentration by Finite Element Analysis

open access: yesOrbital: The Electronic Journal of Chemistry, 2021
Understanding the structure of the electrical double layer (EDL) is of great importance for many different technological and scientific applications, but some information is not always accessible from experiments. In this sense, the aim of this study was

High On-Off Ratio Graphene Switch via Electrical Double Layer Gating

open access: yesIEEE Access, 2020
This paper discusses the production and investigation of novel graphene switches by gating through an electrical double layer (EDL). Controlled voltage biases across a liquid dielectric and graphene induce electrochemical reactions within the dielectric ...

Analysis of impedance measurements of a suspension of microcapsules using a variable length impedance measurement cell

open access: yesJournal of Electrical Bioimpedance, 2012
Electrical impedance measurements of a suspension have to take into account the double layer impedance that results from a very thin charged layer formed at the electrode-electrolyte interface.

Enhancing Output Power of Textured Silicon Solar Cells by Embedding Indium Plasmonic Nanoparticles in Layers within Antireflective Coating

open access: yesNanomaterials, 2018
In this study, we sought to enhance the output power and conversion efficiency of textured silicon solar cells by layering two-dimensional indium nanoparticles (In NPs) within a double-layer (SiNx/SiO2) antireflective coating (ARC) to induce plasmonic ...

Cytoplasmic anion/cation imbalances applied across the membrane capacitance may form a significant component of the resting membrane potential of red blood cells

open access: yesScientific Reports, 2022
Electrical aspects of cell function manifest in many ways. The most widely studied is the cell membrane potential, V m , but others include the conductance and capacitance of the membrane, the conductance of the enclosed cytoplasm, as well as the charge ...

An electrical method to measure low-frequency collective and synchronized cell activity using extracellular electrodes

open access: yesSensing and Bio-Sensing Research, 2016
An electrical method to measure extracellular bioelectrical activity in vitro is presented. This method exploits the Helmholtz capacitive double-layer established at the electrode surface. Small extracellular voltage variations in the order of μVs induce

Enhancement of non-contact friction between metal surfaces induced by the electrical double layer

open access: yesApplied Surface Science Advances, 2021
Casimir and electrostatic non-contact friction between two gold plates, and a gold tip and a gold plate, are calculated taking into account the contribution of the electrical double layer.

Clay micromechanics: Numerical modelling of electrical double-layer interactions to develop particle-based models for clay [PDF]

open access: yesE3S Web of Conferences
Discrete element modelling of clays requires defining the interaction energy between two particles. The Derjaguin, Landau, Verwey and Overbeek (DLVO) theory combining the effect of the van der Waals forces and the Coulombic forces due to the double layer
