Metallic Janus and Patchy Particles
Particle & Particle Systems Characterization, 2012 The concepts of Janus and patchy particles are relatively new in nanoscience. Much effort has been made during recent years to devise and fabricate asymmetric particles with multiple compositions and functionalities due to their interesting properties ...

Multifunctional Photonic Janus Particles
Journal of the American Chemical Society, 2022 Photonic Janus particles with a sphere fused to a cone are created from the phase separation of dendronized brush block copolymers (den-BBCP) and poly(4-vinylpyridine)-r-polystyrene (P4VP-r-PS) during the solvent evaporation of oil-in-water emulsions ...

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

Morphing metal-polymer janus particles.
Advanced Materials, 2022 The direct deformation and shape recovery of micron-sized polystyrene particles via nanoimprint lithography is reported. The recovery of the programmed PS particles can be utilized to create a range of smart Janus particles with contrasting properties in

Janus molecularly imprinted polymer particles
Chem. Commun., 2014 By combining the specific molecular recognition capability of MIPs and the asymmetric structure of Janus particles, the Janus MIP particles which were synthesized via a wax-water Pickering emulsion showed attractive capabilities as self-propelled ...

Thermotaxis of Janus particles. [PDF]
Eur Phys J E Soft Matter, 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

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 ...
