Dipolophoresis of Janus nanoparticles in a microchannel
ELECTROPHORESIS, 2013A nonlinear dipolophoretic analysis is applied to analytically explain the counterintuitive experimental results of Gangwal et al. [16, 17] that an uncharged micro/nanosize dielectric Janus particle is attracted to the wall of a microchannel when exposed to an AC‐uniform electric field in the direction parallel to the no‐slip boundaries.

Thermophoresis of Janus nanoparticles in liquids
Physical Review EIn this work, we investigate the thermophoresis of Janus nanoparticles in liquids through molecular dynamics simulations. Thermophoretic forces acting on cylindrical Janus nanoparticles are calculated through MD simulations by varying the particle size, the heterogenous surface energies, and the mean temperature of the fluid.

Janus Nanoparticles by Interfacial Engineering
Advanced Functional Materials, 2007AbstractNanosized Janus particles were prepared by ligand exchange reactions of a Langmuir monolayer of hydrophobic alkanethiolate‐passivated gold nanoparticles at relatively high surface pressures with hydrophilic thiol derivatives injected into the water subphase. The ligand intercalation between adjacent particles led to impeded interfacial mobility

Synthesis and Applications of Polymeric Janus Nanoparticles
2017Research into Janus particles has received great attention over the past decade. In his Nobel lecture in 1991, Pierre-Gilles de Gennes suggested that asymmetric colloidal particles with different chemical compositions on the two lobes could have a special behaviour at interfaces, and named them “Janus grains.1 Due to their asymmetry, Janus particles ...

Optical manipulation of Janus nanoparticles
CLEO: 2015, 2015We explore optical forces and torques acting on Janus nanoparticles in a plane electromagnetic wave. We find rotationally stable points and propose a scheme for all-optical manipulation of orientation and position of Janus nanoparticles.

Polymer Single Crystal Templated Janus Nanoparticles
Macromolecular Rapid Communications, 2010AbstractTop‐selective surface modification has been widely used for the synthesis of Janus nanoparticles (NPs). Herein we demonstrate that polymer single crystals can serve as generic substrates to immobilize NPs and the resultant NPs are Janus in nature.

Tilting and Tumbling of Janus Nanoparticles at Sheared Interfaces
ACS Nano, 2016We investigate the response of a single Janus nanoparticle adsorbed at an oil-water interface to imposed shear flows using molecular dynamics simulations. We consider particles of different geometry, including spheres, cylinders, and discs, and tune their degree of amphiphilicity by controlling the affinity of their two sides to the fluid phases.

Amphiphilic Janus Twin Single‐Chain Nanoparticles
Chemistry – A European Journal, 2018AbstractIn these years, synthesis and self‐assembly of nanoparticles with various sizes, geometries and compositions have aroused great interest due to their scientific significance and potential applications. The nanoparticles with asymmetric structures are able to self‐assemble into hierarchical structures for constructing functional materials.

Self-Assembly of Triblock Janus Nanoparticle in Nanotube
Journal of Chemical Theory and Computation, 2012We have performed molecular simulations to investigate morphologies and the phase diagram of the self-assembled triblock Janus nanoparticle confined to nanotubes. The triblock Janus nanoparticle is decorated with two hydrophobic caps at the north and south poles with a tunable area, separated by an electrically charged middle band.
