Janus Particles at Liquid−Liquid Interfaces

, 2016
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).

Synthesis of anisotropic Janus composite particles based on polystyrene/urushiol- lanthanum chelate polymer.

PLoS ONE
To expand the potential applications of raw lacquer, snowman-like polystyrene (PS)-urushiol lanthanum (ULa) Janus composite particles were synthesized by emulsion swelling-assisted protrusion from PS/ULa core-shell composite microspheres.

Advances in Janus Nanoparticles

CHIMIA, 2013
The design and synthesis of Janus nanoparticles has attracted great scientific interest in recent years. Novel optical, electronic, magnetic, and superficial properties emerge from their dimensions and unique morphology at the nanoscale ...

Emulsion stabilization with Janus particles

, 2015
Emulsions are dispersions of droplets of one fluid within a second, immiscible fluid and have a wide range of applications from foodstuffs to pharmaceuticals to personal care products and agrochemicals.

Self-assembly of active amphiphilic Janus particles

New Journal of Physics, 2017
In this article, we study the phenomenology of a two dimensional dilute suspension of active amphiphilic Janus particles. We analyze how the morphology of the aggregates emerging from their self-assembly depends on the strength and the direction of the ...

Non-Gaussian statistics for the motion of self-propelled Janus particles: Experiment versus theory [PDF]

, 2013
Spherical Janus particles are one of the most prominent examples for active Brownian objects. Here, we study the diffusiophoretic motion of such microswimmers in experiment and in theory.

Temperature-driven motion of metallic Janus microparticles under nanosecond pulsed laser exposure

JPhys Photonics
Despite extensive studies on the active motion of Janus particles, the interplay between material-dependent energy deposition and pulsed laser illumination remains elusive.

Effect of charge distribution on the electrostatic adsorption of Janus nanoparticles onto charged surface

AIP Advances, 2017
We carried out coarse-grained molecular dynamics simulations to study the electrostatic adsorption of Janus nanoparticles which consist of oppositely charged hemispheres onto charged surfaces.

Janus Particles with Varying Configurations for Emulsion Stabilization

, 2019
Analogous to molecular surfactants, amphiphilic Janus particles can function as surface active agents to stabilize emulsions. For molecular surfactants, the shape and amphiphilicity, described by packing parameters and hydrophilic–lipophilic balance (HLB)

Complex plasma with active Janus particles

, 2023
A two-dimensional complex plasma containing active Janus particles was studied experimentally. A single layer of micrometer-sized plastic microspheres was suspended in the plasma sheath of a radio-frequency (rf) discharge in argon at low pressure.
