Amphiphilic Janus Particles Confined in Symmetrical and Janus-Like Slits. [PDF]
ACS Omega, 2023 We use Monte Carlo simulations to investigate the behavior of Janus spheres composed of attractive and repulsive parts confined between two parallel solid surfaces. The slits with identical and competing walls are studied. The adsorption isotherms of Janus particles are determined, and the impact of the density in the pore on the morphology is ...

Janus particles at liquid−liquid interfaces
Langmuir, 2006 Following recent theoretical predictions, we report on the first experiments on the interfacial activity of so-called Janus nanoparticles (i.e., bifacial particles consisting of a gold and an iron oxide moiety).

Janus balance of amphiphilic colloidal particles
The Journal of Chemical Physics, 2007 We introduce the notion of "Janus balance" (J), defined as the dimensionless ratio of work to transfer an amphiphilic colloidal particle (a "Janus particle") from the oil-water interface into the oil phase, normalized by the work ...

Entropy Production in a System of Janus Particles. [PDF]
Entropy (Basel)Entropy production is a key descriptor of out-of-equilibrium behavior in active matter systems, providing insights into both single-particle dynamics and emergent collective phenomena. It helps determine transport coefficients and phoretic velocities and serves as a crucial tool for understanding collective phenomena such as structural transitions ...

Electrophoresis of active Janus particles [PDF]
The Journal of Chemical Physics, 2019 We theoretically consider the dynamics of a self-propelled active Janus motor moving in an external electric field. The external field can manipulate the route of a Janus particle and force it to move toward the desired targets. To investigate the trajectory of this active motor, we use a perturbative scheme.

Polarization of active Janus particles [PDF]
Physical Review E, 2014 We study the collective motion of Janus particles in a temperature or concentration gradient. Because of the torque exerted by an external or self-generated field, the particles align their axis on this gradient. In a swarm of self-driven particles, this polarization enhances the interactiondriven confinement.
