Emulsion Interfacial Synthesis of Asymmetric Janus Particles

We report a facile nonaqueous emulsion synthesis of colloidal halide perovskite quantum dots by controlled addition of a demulsifier into an emulsion of precursors. The size of resulting CH3NH3PbBr3 quantum dots can be tuned from 2 to 8 nm by varying the amount of demulsifier. Moreover, this emulsion synthesis also allows the purification of these quantum dots by precipitation from the colloidal solution and obtains solid-state powder which can be redissolved for thin film coating and device fabrication. The photoluminescence quantum yields of the quantum dots is generally in the range of 80–92%, and can be well-preserved after purification (∼80%). Green light-emitting diodes fabricated comprising a spin-cast layer of the colloidal CH3NH3PbBr3 quantum dots exhibited maximum current efficiency of 4.5 cd/A, power efficiency of 3.5 lm/W, and external quantum efficiency of 1.1%. This provides an alternative route toward high efficient solution-processed perovskite-based light-emitting diodes. In addition, the emulsion synthesis is versatile and can be extended for the fabrication of inorganic halide perovskite colloidal CsPbBr3 nanocrystals.

N2 - A previously reported oil emulsion technique for the synthesis of large, porous zirconia particles has been modified to overcome problems of nonreproducibility, formation of non-spherical or broken particles, and low yield of chromatographically useful particles. The improved technique described here uses a concentrated sol and an in-line mixer to successfully solve these problems. The results indicate that the stirring rate used to maintain the emulsion during drying has a strong effect on the final particle size.

Since the foundation on 1950, Nihon Emulsion continues manufacturing and building up the synthesis technology of nonionic surfactants over 60 years. Also, continues searching how to contribute to society through the surfactants.
Our unique surfactant "AMITER" and "PYROTER" are both amino acid derivative and widely used for cosmetics use.
For ever and a day, we engaged in research and development for request and demand.

The screen-printing method uses long-established technology that has been applied to numerous fields such as PCB and textile manufacturing. By leveraging our unique aqueous emulsion synthesis technology and a wealth of photoreaction technologies, GOO Chemical has developed materials for making screen masks that are critical in realizing screen-printing.
We aim to develop even higher performance and better quality screen masks making materials in order to realize the production of a series of high performance products using screen-printing.

We have proposed a simple method to synthesize asymmetric Janus polymer particles at an emulsion interface. Morphological evolution of the particles with polymerization and their dependence on some key variables reveal that both cross-linking degree of the particles and interfacial tension difference play key roles in achieving the asymmetric shapes. By selective growth of functional materials onto the desired sides, composition and microstructure of the Janus particles can be controlled. The representative PS/PAM Janus particles are amphiphilic and can be used as solid surfactants to stabilize emulsions, which preferentially orientate at the interface.
