Attraction between Like Charged Surfaces Mediated by Uniformly Charged Spherical Colloids in a Salt Solution
Like-charged macromolecules repel in electrolyte solutions that contain small (i.e. point-like) monovalent coand counterions. Yet, if the mobile ions of one species are spatially extended instead of being point-like, the interaction may turn attractive. This effect can be captured within the mean-field Poisson-Boltzmann framework if the charge distribution within the spatially extended ions is ...
متن کاملChain stiffness and attachment-dependent attraction between polyelectrolyte-grafted colloids.
We report here the effects of chain stiffness and surface attachment on the effective interactions between polyelectrolyte-grafted colloidal particles in monovalent salt obtained using Monte Carlo simulations. Our approach involves computation of the distance-dependent potential of mean force between two polyelectrolyte-grafted colloidal particles treated at a coarse-grained resolution. Two cha...
متن کاملResolving a Mysterious Particle Attraction in Colloids MODELING COLLOIDS EXPLAINING UNEXPECTED ATTRACTION TOWARD A THEORETICAL MODEL FOR IMPROVED MATERIALS
igh school students are taught that, when two electrically charged objects are brought together, a positively charged object will be attracted to a negatively charged object, while two objects with the same charge will repel one another. However, in some everyday materials, it turns out that particles with the same charge can be attracted to one another. Jianzhong Wu, a postdoctoral researcher ...
متن کاملLong-range Attraction between Like-charged Colloids: Simulations and Microgravity Experiments
Deionized dilute charged colloidal systems exhibit gas-liquid and gas-solid coexistence and re-entrant transitions depending on suspensions parameters such as volume fraction, charge density and ionic strength. These observations constitute evidence for the existence of long-range attraction between like-charged colloids. Monte Carlo (MC) simulations using Sogami-Ise pair-potential, which has a...
متن کاملStudy on Colloidal Model of Petroleum Residues through the Attraction Potential between Colloids
The samples of DaGang atmospheric residue (DG-AR), Middle East atmospheric residue (ME-AR), TaHe atmospheric residue (TH-AR), and their thermal reaction samples were chosen for study. All the samples were fractioned into six components separately, including saturates plus light aromatics, heavy aromatics, light resins, middle resins, heavy resins, and asphaltenes. The dielectric permittivity of...
