Investigation of Electrostatic Assembly of Gold Nanoparticles Mediated by Giant Polyoxomolybdate Clusters
… which closely matched the point of aggregate electroneutrality. Successful assembly was demonstrated using UV-vis, DLS, TEM, and zeta-potential analysis. Results indicate that the point at which precipitation occurs is related to charge balance or electroneutrality, and that counter-ions at …

Understanding electrochemistry at the Molecular scale : molecular dynamics methods and applications
… ability to support significant deviations from electroneutrality. This result demonstrates the necessity of carefully reconsidering macroscopic phenomenology when designing nanoscale systems.

Mathematical Modeling of Microscale Biology in Polyelectrolyte Brushes
… to the steady state. The results quantify how electroneutrality is attained through diffusion, ion electrophoresis, spatially-varying permittivity hydration forces, and ion-specific pairing. Brush-Salt interfacial profiles of the electrostatic potential as well as bound and unbound ions are …

Experimental study and modeling analysis of ion transport membranes for methane partial oxidation and oxyfuel combustion
… consistency and conserves site balance and electroneutrality. Charged species diffusion is modeled using the dilute-limit Poisson-Nernst-Planck formulation that accounts for transport due to concentration gradient as well as electromigration. We use the experimental data to extract kinetic …

Studies of Molecular and Colloidal Semiconductors and Their Mass Transport Properties by Voltammetry, Stochastic Electrochemistry, and Electrogenerated Chemiluminescence
… no evidence of migration was observed due to electroneutrality of Fc species.We also performed a detailed study on electrochemical, spectroscopic and electrogenerated chemiluminescence (ECL) properties of three classes of polycyclic aromatic hydrocarbons (PAHs): peropyrenes, chiropeopyrenes, …

Local Structures of Niobium-Containing Cation-Disordered Rocksalt Materials: Cobalt-Free Cathodes for Lithium-Ion Batteries
… and rationalised based on the principle of electroneutrality, combined with the accommodation of Mn Jahn-Teller and Nb second order Jahn-Teller distortions within the material. This cation ordering is found to be highly sensitive to the synthesis conditions and to have significant …

Engineering electroresponsive layer-by-layer thin films
… charge in the film brings in ions and water for electroneutrality, which solubilize the film components. The release of the polyanion dextran sulfate and the small molecule antibiotic gentamicin sulfate were precisely controlled with an electric potential. When PB is reduced, the negative charge …

Development of an EQCM-based sensor for metal ions
… of highly hydrated H+ ions necessary to maintain electroneutrality. Studies on Nafion® layers impregnated with DFA+ and Fe3+ show that while Fe3+ complexes with DFA+, Fe2+ does not and that, upon reduction of the complexed ferric ion, the resultant Fe(II)-DFA+ complex dissociates suggesting that …

Investigation of Charge Transfer in Metal-Organic Frameworks for Electrochemical Applications
… coupled to diffusion of counter ions to balance electroneutrality. While the apparent diffusion coefficient (Dapp) has been employed to describe the overall charge transfer efficiency, independent elucidation of electron and ion diffusion is crucial for providing insights into the mechanism of …

Investigating the role of dithiophosphate in the flotation of base metal sulfides
… the adsorption of the other in order to maintain electroneutrality. It is proposed that these observations provide supporting evidence for the classical Leja-Schulman penetration theory on the respective role of frothers and collectors in flotation. This theory proposes that during bubble-particle …

Ionic separation in electrodialysis : analyses of boundary layer, cationic partitioning, and overlimiting current
Electrodialysis performance strongly depends on the boundary layer near ion exchange membranes. The thickness of the boundary layer has not been clearly evaluated due to its substantial fluctuation around the spacer geometry. In this study, the boundary layer thickness was defined with three …
