Electrode structuring for production of magnetite nanoparticles in water. 水中のマグネタイト微粒子の量産化に向けた電極の設計

admWL

High-throughput production of magnetite nanoparticles prepared by the monopolar arrangement of iron electrodes in water. Based on the works done by a doctoral student from Institut Teknologi Sepuluh Nopember (ITS, Indonesia) and two doctoral students from Tokyo University of Agriculture and Technology (Japan) /doi.org/10.1016/j.ces.2019.02.027 (Chemical Engineering Science, 2019) ◆ナノ粒子製造のための環境に優しいプロセスを提案した。◆水と鉄板以外に化学薬品は必要ない。◆合成ナノ粒子は電気触媒として有望。 *Environmentally friendly process for nanoparticles.*No chemicals… Continue reading Electrode structuring for production of magnetite nanoparticles in water. 水中のマグネタイト微粒子の量産化に向けた電極の設計
