Peng Ni is working with Anat Shahar on kinetic copper isotope fractionation during diffusion processes. In terrestrial processes such as tektite formation and planetary processes such as volcanic eruption on lunar surface, copper behaves as a moderately volatile element and can be lost into the vapor phase during evaporation. Its isotopes are fractionated in this process and part of the fractionation could be due to copper diffusion. His primary goal is to experimentally investigate this process.
