Learn about the realization of the kilogram at the National Metrology Institute of Japan (NMIJ) with the X-ray crystal density method. This is a great opportunity to learn about this topic from Dr. Naoki Kuramoto, who significantly contributed to the determination of the Planck constant in the new definition of the kilogram by measuring the volume of 28Si-enriched spheres.
