Amphiphilic Bowl-Shaped Janus Particles Prepared via Thiol–Ene Click Reaction for Effective Oil–Water Separation [PDF]
Nanomaterials, 2023 Janus particles for oil–water separation have attracted widespread attention in recent years. Herein, we prepared a bowl-shaped Janus particle that could rapidly separate oil and water through a thiol–ene click reaction and selective etching.

Arrested-motility states in populations of shape-anisotropic active Janus particles. [PDF]
Sci Adv, 2022 The emergence of large-scale collective phenomena from simple interactions between individual units is a hallmark of active matter systems. Active colloids with alignment-dominated interparticle interactions tend to develop orientational order and form ...

Synthesis of Janus Polydiacetylene Sensor Particles with Thermochromism and Solvatochromism Properties [PDF]
Small StructuresThe first report is presented on the fabrication of anisotropic Janus polydiacetylene (PDA) microparticles with dual colorimetric properties. Spherical proto‐PDA particles are initially created by drying an emulsion containing 10,12‐pentacosadiynoic acid

Phase diagram of Janus Particles [PDF]
Physical Review Letters, 2009 We deeply investigate a simple model representative of the recently synthesized Janus particles, i.e. colloidal spherical particles whose surface is divided into two areas of different chemical composition.

Electrostatic Interactions between Janus Particles [PDF]
The Journal of Chemical Physics, 2012 In this paper we study the electrostatic properties of `Janus' spheres with unequal charge densities on both hemispheres. We introduce a method to compare primitive-model Monte Carlo simulations of the ionic double layer with predictions of (mean-field ...

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

Inferring non-equilibrium interactions from tracer response near confined active Janus particles. [PDF]
Sci Adv, 2021 Activity-induced osmotic flows near surfaces play a key role in determining non-equilibrium interactions with active particles. Chemically active Janus particles sustain non-equilibrium spatial variations in the chemical composition of the suspending ...
