Title: Masafumi Nakaya: Inventor of a Nanoparticle Production Method.
Introduction
Masafumi Nakaya is an inventor associated with Tokyo, Japan. His patent work includes a method for producing cubic-crystal lithium manganese oxide (LiMnO₂) nanoparticles.
Latest Patents
Nakaya’s listed patent, “Cubic Crystal Alkali Metal Manganate Nanoparticle Production Method and Cubic Crystal LiMnO₂ Nanoparticles Produced Using Same,” describes producing nanoparticles by combining an organic solvent, manganese oxide nanoparticles, and lithium amide in a reaction vessel, then heating the mixture in an inert atmosphere. The resulting particles are washed and recovered.
The method preferably uses wurtzite-type manganese oxide nanoparticles. This approach can produce LiMnO₂ nanoparticles with particle sizes substantially similar to those of the manganese oxide starting material. Controlling the reaction temperature can also produce nanoparticles with a hollow structure. Nakaya is listed with 1 patent.
Career Highlights
Nakaya’s listed affiliations include Stanley Electric Corporation and Tohoku University.
Collaborations
His listed coworkers include Takuya Kazama and Wataru Tamura.
Conclusion
Masafumi Nakaya’s patent work focuses on producing cubic-crystal LiMnO₂ nanoparticles, with process conditions that can influence particle size and structure.
