Multiscale Simulation Method for Self-Organization of Colloidal Nanoparticles during Drying

Multiscale simulation method for self-organization of nanoparticles in dense suspension

This paper presents a multiscale simulation method for self-organization of nanoparticles in a dense suspension. The method consists of a solid–liquid two-phase model, in which the flow of solvent and the motion of nanoparticles are treated by an Euler–Lagrange hybrid scheme with a dual time stepping. The method also includes various multiscale forces whose characteristic length and time scales...

Self-lubricating nanoparticles: self-organization into 3D-superlattices during a fast drying process.

Fluorinated tetraethylene glycol-stabilized Au nanoparticles (FTEG-AuNPs) were well-dispersed in general polar organic solvents, such as methanol (MeOH) and THF. The cast film of FTEG-AuNPs on a TEM grid and a glass substrate was found to form a highly ordered 3D-superlattice assembly, whereas tetraethylene glycol-stabilized AuNPs (TEG-AuNPs) provide an amorphous AuNP aggregation. These data in...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Drying-mediated assembly of colloidal nanoparticles into large-scale microchannels.

Large-scale highly ordered microchannels were spontaneously and rapidly created by simply drying the colloidal nanoparticle suspension on a rigid substrate. Interestingly, free evaporation of colloidal suspension yielded radially aligned microchannels, while constrained evaporation that was rendered by the use of confined geometries composed of either two nearly parallel plates or a slide place...
