The fate of nitrogen during core-mantle separation on Earth
Abstract. Nitrogen, the most dominant constituent of Earth's atmosphere, is critical for the habitability and existence of life on our planet. However, its distribution between Earth's major reservoirs, which must be largely influenced by the accretion and differentiation processes during its formative years, is poorly known.
Nitrogen separation from air by pressure swing adsorption
