The World Research Unit (B-1) at Nagoya University “Reaction Infography (R-ing)” has been started at Research Center for Materials Science, Nagoya University, since April 2019. The R-ing unit aims to prepare the new concept of reaction infography by collaborative researches on reaction imaging (ultrafast spectroscopy, operando imaging, chemical imaging etc.), informatics (data mining, unsupervised learning etc.), and materials science. In this unit, we discuss new collaborative works across different research fields and create new science for future developments in materials science.
