Structure formation in binary colloids.
A theoretical study of the structure formation observed very recently [W. D. Ristenpart, I. A. Aksay, and D. A. Saville, Phys. Rev. Lett. 90, 128303 (2003)] in binary colloids is presented. In our model solely the dipole-dipole interaction of the particles is considered, electrohydrodynamic effects are excluded. Based on molecular dynamics simulations and analytic calculations we show that the ...
متن کاملLattice Boltzmann for Colloids in Binary Fluids
The implementation of solid colloidal particles suspended in a binary fluid mixture via the lattice Boltzmann method is described. To represent colloids in a binary mixture, boundary conditions for mass and momentum at the solid-fluid interface are extended to include a conserved compositional order parameter. The parallelisation of the fluid-particle problem is addressed, and its scaling inves...
متن کاملSpontaneous Formation of Eutectic Crystal Structures in Binary and Ternary Charged Colloids due to Depletion Attraction
Crystallization of colloids has extensively been studied for past few decades as models to study phase transition in general. Recently, complex crystal structures in multi-component colloids, including alloy and eutectic structures, have attracted considerable attention. However, the fabrication of 2D area-filling colloidal eutectics has not been reported till date. Here, we report formation of...
متن کاملStructure formation in a binary monolayer of dipolar particles.
We propose an experimental technique for an easy to control realization of a binary dipolar monolayer where the two components have oppositely oriented dipole moments constrained perpendicular to the plane of motion without the application of an external field. The experimental setup ensures that hydrodynamic effects do not play a crucial role in the structure formation, the particles move dete...
متن کاملFormation, photodissociation and structure of chromium/phosphorus binary cluster ions
Chromium/phosphorus binary cluster ions, [Cr(n)P(m)](+/-), produced by laser (532nm) ablation on a tablet of well-mixed chromium and red phosphorus powder, were studied with a home-built tandem time-of-flight (TOF) mass spectrometer. The clusters thus formed are mostly rich in phosphorus. There is an odd-even oscillation in the intensity of the [CrP(m)](+) series, i.e. the mass peaks of even m ...
