Capture of heavy hydrogen isotopes in a metal-organic framework with active Cu(I) sites. [PDF]
Nat Commun, 2017 The production of pure deuterium and the removal of tritium from nuclear waste are the key challenges in separation of light isotopes. Presently, the technological methods are extremely energy- and cost-intensive.

Transport of hydrogen isotopes through interlayer spacing in van der Waals crystals [PDF]
Nature Nanotechnology, 2018 Atoms start behaving as waves rather than classical particles if confined in spaces commensurate with their de Broglie wavelength. At room temperature this length is only about one ångström even for the lightest atom, hydrogen.

Triple Oxygen Isotope Paleoaltimetry of Crystalline Rocks
Frontiers in Earth Science, 2021 Triple oxygen isotopes of hydrothermally altered minerals from crystalline rocks can be used to determine past elevations of mountain ranges. This method uses all three isotopes of oxygen (16O, 17O, and 18O) to create arrays that can be extrapolated back
