"Advanced Research Infrastructure for Materials and Nanotechnology Project (ARIM)" by MEXT#1) was started on April 2021 in order to provide the latest user facilities and create industrial innovations. The institute of scientific and industrial research (ISIR) and research center for ultra-high voltage electron microscopy (UHVEM) participated in the MEXT project, and “Advanced Research Infrastructure for Materials and Nanotechnology Open Facilities in Osaka University” was established in Osaka University. We totally support domestic nanotechnological researchers by providing three platforms; (1) Characterization & analysis, (2) Nanofabrication, and (3) Molecular & material synthesis. Each platform consists of several facilities of other domestic universities and institutes and the facilities in the platform also cooperate among them. "Advanced Research Infrastructure for Materials and Nanotechnology Open Facilities in Osaka University" contributes to creations of novel nano-materials and nano-devices though the supports concerning combinations of various materials such as metal, oxide, organic and bio, or different research fields. We also cooperate with regional companies/universities/institutes on the project, and bring up future nanotech key persons. Advanced Research Infrastructure for Materials and Nanotechnology Open Facilities in Osaka University” will play the role of a center of regional industrial innovation. #1) the Ministry of Education, Culture, Sports, Science and Technology (MEXT)
