開発の事例:微粒子の合成と構造化 Examples of Tecnologies: Synthesis & Structuring of Nanoparticles (2018-2019)

浮遊する微粒子(ナノ粒子)の構造化と集積化について、従来まで考証されていなかった粒子群の輸送に対する「駆動力のバランス」の視点からの技術手法を開発した。We have developed techniques for synthesis and structuring suspended particulates (nanoparticles), based on the viewpoint of "balance of driving force" for the transportation.
