Thermotaxis of Janus particles [PDF]

open access: yesThe European Physical Journal E, 2021
Abstract The interactions of autonomous microswimmers play an important role for the formation of collective states of motile active matter. We study them in detail for the common microswimmer-design of two-faced Janus spheres with hemispheres made from different materials. Their chemical and physical surface properties

The concept of a miniature all-optical space switch based on the photonic hook effect

open access: yesКомпьютерная оптика, 2021
We propose and discuss main properties of a new concept of an all-optical dielectric two-channel wavelength-selective switch based on the photonic hook effect. A prototype of such a de-vice based on dielectric microstructures with broken symmetry of both

Spontaneous Agglomeration of Fluorinated Janus Particles and Its Effect on the Adsorption Behavior of Oil-Air Surfaces

open access: yesFrontiers in Chemistry, 2021
Based on the Pickering emulsion template method, two types of Janus particles with different relative amphiphilic areas for stabilizing non-aqueous foam were synthesized.

Janus particles with tunable patch symmetry and their assembly into chiral colloidal clusters

open access: yesNature Communications, 2023
Janus particles, which have an attractive patch on the otherwise repulsive surface, have been commonly employed for anisotropic colloidal assembly. While current methods of particle synthesis allow for control over the patch size, they are generally ...

Plant protein nanogel–based patchy Janus particles with tunable anisotropy for perishable food preservation

open access: yesFood Frontiers, 2023
Janus particles with anisotropic surfaces possess considerable potential for biological functionalization. However, little is known about the effect of surface anisotropy of Janus particles on the shelf life of perishable food.

Active Janus particles in a complex plasma

open access: yesPhysical Review Research, 2020
Active Janus particles suspended in a plasma were studied experimentally. The Janus particles were micron-size plastic microspheres, one half of which was coated with a thin layer of platinum. They were suspended in the plasma sheath of a radio-frequency

Amphiphilic Bowl-Shaped Janus Particles Prepared via Thiol–Ene Click Reaction for Effective Oil–Water Separation

open access: yesNanomaterials, 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.

Electrophoresis of active Janus particles [PDF]

open access: yesThe 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.

On the Elastic Description of a Spherical Janus Particle

open access: yesReviews on Advanced Materials Science, 2018
The elastic problem of a spherical core-shell particle with a truncated core is solved within the isotropic classical theory of elasticity. A transition to a Janus particle consisting of two unequal spherical segments with lattice mismatch is ...
