Electrostatic Potentials at Solid/Liquid Interfaces*
This review deals with electrostatic potentials within solid/electrolyte interfaces. The electrostatic potentials of several planes are defined and discussed: the inner surface potential affecting the state of charged surface species due to interactions with potential determining ions (Ψ0), the potential affecting the state of associated counterions (Ψβ), the potential at the onset of diffuse l...
متن کاملFast Surface Particle Repulsion
A fast algorithm for simulating particle repulsion on surfaces is described. Particles are distributed across a surface and made to repel. Calculating pairwise repulsion between n particles costs O(n2) in general, but if the energy potential drops off very rapidly, repulsion can be simulated in O(n) time. This is accomplished using a simple grid data structure with spherical range queries. Part...
متن کاملElectrostatic Repulsion Governs TDP-43 C-terminal Domain Aggregation
TDP-43 is a protein with multiple crucial functions in RNA processing and mRNA-protein (mRNP) particle formation, two processes that are strongly implicated in amyotrophic lateral sclerosis (ALS) and frontotemporal lobar dementia (FTLD) [1]. The recently published structural characterization by Lim, Wei, Lu, and Song [2] of the complete (residues 262–414) C-terminal domain (CTD) of TDP-43 and t...
متن کاملControlling Nonpolar Colloidal Asphaltene Aggregation by Electrostatic Repulsion
While aromatic chemicals are applied to petroleum oil systems to thermodynamically prevent asphaltene precipitation, amphiphilic dispersants can truncate the precipitation process and create stable suspensions of asphaltene colloids in the submicrometer size range. Bulk sedimentation and dynamic light scattering have shown that stabilizing dispersants inhibit colloidal asphaltene aggregation at...
متن کاملInteractions and stress relaxation in monolayers of soft nanoparticles at fluid-fluid interfaces.
Nanoparticles with grafted layers of ligand molecules behave as soft colloids when they adsorb at fluid-fluid interfaces. The ligand brush can deform and reconfigure, adopting a lens-shaped configuration at the interface. This behavior strongly affects the interactions between soft nanoparticles at fluid-fluid interfaces, which have proven challenging to probe experimentally. We measure the sur...
