Active geology—and the large-scale chemistry it can drive—requires significant amounts of heat. Dwarf planets near the far edges of the Solar System, like Pluto and other Kuiper Belt objects, formed ...

Hydrogen is in great demand due to its promising role as a sustainable resource in the energy transition. Researchers have made an important breakthrough in the efficient and cost-effective provision ...

Deuterium, a heavier but less abundant version of the hydrogen atom, has many practical applications. Unfortunately, producing deuterium and using it to protect silicon-based semiconductors requires a ...

The physicochemical and biological properties of hydrogen-bonded systems are significantly affected by nuclear quantum effects including zero-point energies of vibrational modes, proton delocalization ...

Deuterium is a stable isotope of hydrogen, which, unlike “normal” hydrogen atoms, or protium, also contains a neutron. The isotope deuterium has one proton, one neutron and one electron. One out of ...

As part of the Hydrogen Isotopes 1,2,3H Research Training Group, a team from Leipzig University and TU Dresden has made a significant advancement in the effective and economical provision of isotopes, ...

The IAEA is launching a new 5-year Coordinated Research Project (CRP) to assemble, validate and distribute fundamental data relevant for nuclear fusion energy development. The CRP is expected to ...
