Tracing the diffusion of carbon isotopes using atomic-scale vibrational spectroscopy

A team of researchers affiliated with multiple institutions in Japan has developed a technique for tracing the diffusion of carbon isotopes using atomic-scale vibrational spectroscopy. In their paper published in the journal Nature, the group describes how they used isotopic imaging of 12C carbon atoms embedded in 13C graphene to monitor self-diffusion. Jordan Hachtel, with Oak Ridge National Laboratory, has published an outline of recent research involving attempts to detect isotopes with high ...
