We study the irreversible aggregation of films of patchy spherical colloids with directional and selective interactions. We report a crossover of the interfacial roughening from the Kardar-Parisi-Zhang (KPZ) to the KPZ with quenched disorder (KPZQ) universality class when the difference between the strong and weak bonds is sufficiently large. We calculate the critical exponents and identify the crossover between the two regimes.

Kinetic interfaces of patchy particles

New evidence is presented that the tricritical point, observed in systems of particles with flexible patches, is in thetricritical directed percolation universality class, and that the critical regime is inThe Kardar-Parisi-Zhang with quenched disorder universalityclass.

Effect of the number of patches on the growth of networks of patchy colloids on substrates

We investigate numerically the irreversible aggregation of patchy spherical colloids on a flat substrate. We consider n-patch particles and characterise the dependence of the irreversible aggregation

Relaxation dynamics of functionalized colloids on attractive substrates.

Particle-based simulations are performed to study the post-relaxation dynamics of functionalized (patchy) colloids adsorbed on an attractive substrate. Kinetically arrested structures that depend on

Nonequilibrium self-organization of colloidal particles on substrates: adsorption, relaxation, and annealing

The self-organization of functionalized colloids (also known as patchy colloids) on attractive substrates is discussed and the use of annealing cycles to overcome kinetic barriers and drive the relaxation towards the targeted structures is explored.

Large-scale kinetic roughening behavior of coffee-ring fronts.

We have studied the kinetic roughening behavior of the fronts of coffee-ring aggregates via extensive numerical simulations of the off-lattice model considered for this context [Dias et al., Soft

Interaction anisotropy and the KPZ to KPZQ transition in particle deposition at the edges of drying drops.

The numerical results corroborate experimental observations and suggest that the deposition transition can stem from interparticle interaction anisotropy, and possible extensions of the model to other systems are discussed.

Effect of anisotropy on the formation of active particle films.

Active colloids belong to a class of nonequilibrium systems where energy uptake, conversion, and dissipation occur at the level of individual colloidal particles, which can lead to particles'

Physico-chemical foundations of particle-laden fluid interfaces

The study of particle-laden interfaces deserves attention to provide a comprehensive explanation on the complex relaxation mechanisms involved in the stabilization of fluid interfaces.

Crossover from three- to six-fold symmetry of colloidal aggregates in circular traps.

This work considers a suspension of spherical particles interacting through an isotropic repulsive potential and a three-fold symmetric attractive interaction, confined in circular potential traps in 2d and finds that, due to the competition between the interparticle and the external potentials, the particles self-organize into structures with three- or six-fold symmetry, depending on the width of the traps.



Phase diagram of patchy colloids: towards empty liquids.

Theoretical results suggest that the reduction of the number of bonded nearest neighbors offers the possibility of generating liquid states with temperature T lower than the liquid-gas critical temperature with a vanishing occupied packing fraction (phi), a case which can not be realized with spherically interacting particles.

Nonequilibrium growth of patchy-colloid networks on substrates

Patchy colloids with highly directional interactions are ideal building blocks to control the local arrangements resulting from their spontaneous self-organization. Here we propose their use,

Mixtures of functionalized colloids on substrates.

Two mechanisms of mass transport are compared: diffusion and advection and an optimal fraction is found that maximizes the density of the aggregate in the diffusive case and for advective transport.

Criticality of colloids with distinct interaction patches: the limits of linear chains, hyperbranched polymers, and dimers.

There is no critical point when in(AA) vanishes despite the fact that AA bonds alone cannot drive condensation, yielding three different types of condensation.

How patchy can one get and still condense? The role of dissimilar patches in the interactions of colloidal particles

We investigate the influence of strong directional, or bonding, interactions on the phase diagram of complex fluids, and in particular on the liquid–vapour critical point. To this end we revisit a

Precursors of order in aggregates of patchy particles.

By calculating the probability distribution functions of various rotational invariants, this work can identify the precursors of orientation order in amorphous phase and suggest a significant correlation between rotational order in the studied liquids with the corresponding crystalline phases.

Percolation of colloids with distinct interaction sites.

We generalize the Flory-Stockmayer theory of percolation to a model of associating (patchy) colloids, which consists of hard spherical particles, having on their surfaces f short-ranged-attractive

Recent progress on patchy colloids and their self-assembly

Recent progress which has been made in the synthesis and self-assembly of patchy colloids is reviewed and future directions as well as unresolved challenges are discussed.

Properties of patchy colloidal particles close to a surface: a Monte Carlo and density functional study.

This work investigates the behavior of a patchy particle model close to a hard-wall via Monte Carlo simulation and density functional theory (DFT), and finds that the density profile near the wall crosses over from a typical high-temperature adsorption profile to a low-tem temperature desorption one, for the isochore close to coexistence.

Equilibrium self-assembly of colloids with distinct interaction sites: thermodynamics, percolation, and cluster distribution functions.

There is fairly good agreement between theoretical and numerical results both for the thermodynamic (number of bonds and phase coexistence) and the connectivity properties of the model (cluster size distributions and percolation locus).
