Tohoku Univ. Technology：Amorphous nanoparticles, production method and dispersion: T16-087
Easy production of well-dispersed amorphous nanoparticles at low temperature
Liquid quenching method and atomization method are known as conventional methods of producing amorphous particles. However, the amorphous particle size obtained by these methods is relatively large and it has been difficult to obtain nanometer order amorphous nanoparticles, including amorphous tissue. Although chemical and arc plasma discharge methods are known to produce metal nanoparticles, the application of those methods are not easy due to the formation of secondary particles and segregation. Furthermore, it is also difficult to obtain large quantities of nanoparticles. This invention is able to provide amorphous nanoparticles, its production method with excellent dispersibility at relatively low temperatures, and amorphous nanoparticle dispersions. This invention includes the process of obtaining a dispersion with a solid-state metal comprising an alloy and a reducing dispersant, and the process of irradiating the dispersion with ultrasound in order to obtain amorphous nanoparticles containing an amorphous structure from the solid-state metal.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
