Pioneers in extremely small sub-nanoparticle synthesis seeking novel materials that fire the imagination
Nanoparticles are employed extensively in the field of engineering as one of the most important
nanotechnology
materials, and there is fierce global competition in research and development. To date, however, the
properties of sub-nanoparticles have not been fully characterized, which means progress in establishing
methods of the synthesis has been hindered. Of special note is that there is as yet no universal method
of assembling and blending the more than 90 metallic elements contained in the periodic table of
elements
with a predetermined number of dissimilar metallic atoms.
This project was established to create sub-nano metal particles in which the number of atoms is controllable,
and sub-nano-hetero metal particles made from the precise blending of dissimilar elements at the atomic
level with the goal of creating new next-generation functional materials.
Specifically, we are synthesizing sub-nanoparticles made through the precise formulation of similar
or dissimilar elements with predetermined numbers of atoms utilizing precision polymers (dendrimers)
with regular geometrical structures. We call this an "Atom Hybrid", and aim to create sub-nanoparticles
that have innovative next-generation functions. Clarifying the chemical and electromagnetic properties
of new sub-nanoparticles and positioning new materials will allow us to explore new chemical science.
