Title: Masayuki Ueda: Innovator in Fine Metal Particles

Introduction

Masayuki Ueda is a distinguished inventor based in Tsukuba, Japan. He has made significant contributions to the field of materials science, particularly in the development of fine metal particles and fine metal oxide particles. With a total of four patents to his name, Ueda's work has the potential to impact various industries.

Latest Patents

Ueda's latest patents focus on a process for producing fine metal particles and fine metal oxide particles in dry powder form. This innovative process allows for the creation of extremely fine particles that maintain a good dispersion state without coagulation, even when not stored in a dispersion solvent. The method involves dispersing fine metal particles or fine oxide metal particles with a surface oxidation film in an organic solvent. The particles are then covered with agent molecules that contain functional groups capable of forming coordinative bonds with metal. After removing the dispersion solvent and washing the particles with a polar solvent, the excess covering agent molecules are eliminated without damaging the protective layer. Finally, the polar solvent is evaporated, resulting in a stable dry powder.
