Pickering Janus Emulsions Stabilized with Gold Nanoparticles

Langmuir, 2021
We report a modified approach to the batch scale preparation of completely engulfed core-shell emulsions or partially engulfed Janus emulsions with colorful optical properties, containing water, olive oil, and silicone oil. The in situ reduction of gold chloride, forming gold nanoparticles (AuNPs) at the olive oil interface in the absence or presence ...

Magnetic-mesoporous Janus nanoparticles

Chem. Commun., 2011
Novel multifunctional magnetic-mesoporous Janus particles with controlled aspect ratio were developed by a simple one-step synthesis approach. Due to their superior magnetic properties and well-defined pore structures, these particles will be important in drug delivery, molecule targeting, cellular imaging, and as building blocks for the assembly of ...

Janus Nanoparticles: Preparation, Characterization, and Applications

Chemistry – An Asian Journal, 2013
AbstractIn chemical functionalization of colloidal particles, the functional moieties are generally distributed rather homogeneously on the particle surface. Recently, a variety of synthetic protocols have been developed in which particle functionalization may be carried out in a spatially controlled fashion, leading to the production of structurally ...

Adhesion Force Studies of Janus Nanoparticles

Langmuir, 2007
Janus nanoparticles represent a unique nanoscale analogue to the conventional surfactant molecules, exhibiting hydrophobic characters on one side and hydrophilic characters on the other. Yet, direct visualization of the asymmetric surface structures of the particles remains a challenge.

Segmental Janus nanoparticles of polymer composites

Chemical Communications, 2019
We demonstrate a facile yet robust “plasma etching and grafting” strategy to prepare Janus nanoparticles coated with binary polymer brushes on two different sides. The ratio of two types of polymers can be tailored by tuning the plasma etching power.

Sonochemical Synthesis of Magnetic Janus Nanoparticles

Langmuir, 2010
The sonochemical synthesis of nanosized surface-dissymmetrical (Janus) particles is described. The Janus particles were composed of silica and polystyrene, with the polystyrene portion loaded with nanosized magnetite particles. It is shown that the Janus particles can be used to form kinetically stable oil-in-water emulsions that can be spontaneously ...

Janus Nanoparticle Coupled Double‐Network Hydrogel

Macromolecular Rapid Communications, 2022
AbstractFor double network (DN) hydrogels, their performance can be tuned by adjusting the interaction between their two networks. A novel DN hydrogel toughening approach is proposed by employing Janus nanoparticles (JNs) as crosslinkers to gain a conjoined‐network hydrogel.

Synthesis and interfacial activity of PMMA/PtBMA Janus and homogeneous nanoparticles at water/oil interfaces [PDF]

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2018
Polymethylmethacrylate/poly-tert-butylmethacrylate Janus nanoparticles were synthesized by the electrohydrodynamic co-jetting method. The Janus character of these nanoparticles was visualized through super-resolution imaging with Structured Illumination ...
